According to recommendations by the United States Environmental Protection Agency, as well as the Department of Housing and Urban Development, a septic tank should be at least 50 feet away from a well that is used for drinking water.
- The health and safety regulations in most states require that any containers for waste, including septic tanks, should be at least fifty feet away from any well. However, the drain field for the septic tank will need to be one hundred feet away.
How far should a septic tank be from a water source?
The distance between the septic tank and borewell is 15 ft and the dimension of the septic tank is 11X6X7 ft.
How far should the soak pit be from the septic tank?
The ideal distance between them should be 30 m i.e. 100 ft. If you provide septic tank very near to the borewell, the aquifer i.e. ground water is likely to get contaminated by the waste water from the soak pit.
Can high water table affect septic system?
A high water table on the property around your septic tank can hinder the drain field’s ability to absorb and filter the wastewater. This may cause the drain field to be too heavily saturated, which might lead to a septic system backup.
How high should the water level be in a septic tank?
A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).
How far is distribution box from septic tank?
The D-box is normally not very deep, often between 6″ and two feet to the top of the box. You may also see a pattern of parallel depressions, typically about 5 feet apart, that mark the individual drainfield leach lines. The D-box will at or near end of the drainfield area that is closest to the septic tank.
How close to a septic tank can I build a deck?
It is usually not a good idea to build a deck near or on top of a septic tank. Most zoning ordinances will require that you maintain at least a 5′ setback from an underground septic system.
Is soak pit necessary for septic tank?
Need for Soak Pit The primary treatment unit can be a septic tank, a biogas settler, anaerobic baffled reactor, twin-pits etc. For this partial treatment, most of the wastewater management system needs a soak pit.
How do I calculate the size of my septic tank and soak pit?
Step- One
- No of persons per family = 6 nos.
- Water supply = 200 lits/day.
- Sewage generation = 85 % of water supply.
- Detention period = 24 Hours.
- Cleaning period = One year.
- Length = 4 x Breath, Height = 1.5 meter.
- Sludge Deposit = 40 lit/person/year.
- Minimum freeboard = 300mm.
How far should a soak pit be from the house?
Soakage devices must be at least 2m from boundaries, buildings, wastewater pipes or manholes. a) Drill a 100mm or 150mm diameter hole to at least the expected depth of the soak pit. If groundwater is encountered then this shall be taken as the maximum depth of the soak pit.
What is considered a high water table?
High water tables are often above the level of basement floors or crawlspaces. This almost always causes flooding in these areas. The denser the soil is, the slower the movement of the water (percolation) of the water through the soil occurs.
How do I lower my water table in my yard?
You can use a water well to lower the groundwater table elevation by pumping water from the ground. Continuously pump a groundwater well to lower the water table. Install a groundwater well or use an existing well on your property for the project.
How do you know if your water table is high?
A telltale sign of a high water table is if your neighbors experience similar flooding issues or if your home is near a water source such as a lake, river, or marsh.
How do you know your septic tank is full?
A septic tank is considered “overfull” when the water level is at the very top of the tank. If the septic system’s absorption field stops accepting the water, it sits in the outflow pipe and backs up, overfilling the tank.
Can you put too much water in a septic tank?
Excessive water is a major cause of system failure. Too much water from laundry, dishwasher, toilets, baths, and showers may not allow enough time for sludge and scum to separate. The less water used, the less water entering the septic system, resulting in less risk of system failure.
Can a septic tank never be pumped?
What Are the Consequences of Not Pumping Your Tank? If the tank is not pumped, the solids will build up in the tank and the holding capacity of the tank will be diminished. Eventually, the solids will reach the pipe that feeds into the drain field, causing a clog. Waste water backing up into the house.
Septic Systems and High Water Tables — Water Quality
Septic systems and high water tables are two issues that need to be addressed. Authored by Tom Scherer, Irrigation and Water Resources Specialist, and Home Septic Systems. The North Dakota State University Extension Service Local ground water levels have been elevated as a result of above-average rainfall last autumn, which has resulted in many residential septic systems being waterlogged or temporarily flooding. This causes drains in the house to flow slowly and toilets not to flush correctly.
One of the most important parts of a septic system is the tank, which collects and biologically breaks down solid waste; the other is the drainfield, which serves to offer extra biological treatment while also infiltrating wastewater into the earth.
Any circumstance that blocks or slows the passage of water through the septic system has the potential to produce complications.
This will result in the tank being overflowing and filling with groundwater rather than waste water from the home.
- It is at this point that the waste water from the house is unable to pass freely through the septic system.
- Because of the high water table circumstances that might arise, you may need to treat your septic tank as a holding tank and have it professionally cleaned and pumped on a regular basis.
- A tank that has had more than half its contents removed may attempt to float out of the earth, resulting in damage to the tank’s inlet and outlet pipes.
- Raw sewage on the ground (or in the snow) can be a health danger since it can be trampled by children and dogs, and it can also flow into a watercourse, causing contamination.
- Some tips to assist your septic system in dealing with a high water table are as follows: 1.Reduce the amount of water used in the residence.
- Water that is introduced to the septic system at the rate of one drop every 15 seconds might build up to a significant amount of extra water.
- Avoid draining water from a basement sump pump into the septic system.
It is not permissible to allow water to drain into the drainfield area from roof gutters or the sump pump.
Laundry services are available at laundromats.
Only run the dishwasher when it is completely full.
Always keep in mind that the drainfield was created to infiltrate the quantity of water that would ordinarily be released from the home.
If your domestic plumbing does not function properly after the water table has dropped, it is possible that the drainfield or septic tank has been damaged.
As a result of the shifting, the input and outflow pipes from the septic tank may get partially clogged.
In addition, particles from the tank might clog the inlet and outflow pipes, causing them to get clogged. Request that a qualified and licensed septic tank pumper or septic system installation inspect and evaluate the problem.
Tips For Combating A High Water Table For Your Septic System – Learning About Septic System Care and Usage
Blog For those who are contemplating the construction of an addition to an existing home on a parcel of property where the city sewage system will not reach, a septic system installation should be considered. Septic tanks are a practical option, but they have their own set of problems that must be taken into account. When purchasing a home with a high water table, for example, you must evaluate how the high water table may effect your plumbing system. This article will go over some of the fundamentals you should know about high water tables and their impact on septic system performance.
- Septic systems must have the ability to leak waste water from the septic tank to the drain field in order to function properly.
- As a result, the water table, which refers to the uppermost layer of water under the ground surface, must be sufficiently low in order for the soil in the region to filter the waste water.
- This might cause the drain field to become too saturated, which could result in a septic system blockage.
- The presence of a high water table on your land will not automatically prevent you from constructing a septic tank on it.
- Begin by selecting a tank that is one or two sizes larger than you anticipate you will want during high demand periods.
- In addition, coordinate with your septic tank contractor to plan regular tank pumping.
- If you regularly have your tank pumped once every five years, you might want to consider having it done every two or three years rather than once every five.
- This aids in the filtration of toxins and the cleaning of wastewater before it reaches the drain field or the ocean.
- You can see from the information provided here that a high water table may provide a difficulty for your new septic system, but it does not rule out the possibility of installing one.
Glanborough Pumping provides services such as septic systems, which you can learn more about here. 29th of April, 2016 –
Can I Install a Septic Tank if my Property has a High Water Table?
Water sources protected by septic systems are used by homeowners who reside outside the service area of municipally treated water systems to provide for their needs. When it comes to the operation and maintenance of a standard septic system, rising water tables provide major issues.
The Relationship between a Septic System and the Water Table
When water seeps through the earth’s surface, it forms two layers. The uppermost layer is composed primarily of water, with minor amounts of soil, rock, and air. The second stratum is comprised of groundwater. Because the groundwater layer is so densely packed with water, there are no air gaps like there are in the upper layer. The water table refers to the top plane of groundwater that is above the surface of the earth. Depending on where you live, the depth of your water table can range from a few feet to several thousand feet below the surface of the earth.
Underground septic systems are generally comprised of two components: a tank and a drain field.
As a result of groundwater infiltrating a drainfield, the amount of discarded household water that the drain field can accept is reduced.
Solutions to High Water Tables
Like all septic systems, it is critical for homeowners to anticipate and plan for typical usage requirements, such as those for laundry, bathing, toilet use, and kitchen use, and to ensure that an expert properly designs, installs, inspects, and maintains the system to accommodate the necessary capacity. Additionally, homeowners with high water tables may find that it is sufficient to just have the septic tank commercially pumped more regularly than once a year. This alleviates the problem of volume while also preventing tainted water from coming above ground in dangerous ways or from channeling via pipes back into the home’s plumbing system.
Recirculating Sand Fill (RSF)
Recirculating Sand Fill systems are a viable option for treating pathogens in water before it reaches the drain field, as opposed to traditional methods. They are regarded to be cost-effective, and they require minimum upkeep and upkeep. RSF systems make use of a septic tank, a sand filter, and drain fields to dispose of waste. Wastewater is transferred from the septic tank to a recirculating tank, where it is passed through a sand filter up to five times before being discharged into the drain field for ultimate treatment and disposal.
Reduce Water Use to Reduce Risk
All homes who have septic systems may take efforts to ensure that their influence on the surrounding environment is as minimal and responsible as it possibly can be. First and foremost, it is critical to limit water use. If you want to save money on water, consider doing your washing at a Laundromat, lowering the number of daily showers or baths, and only running the dishwasher when it is completely full. Control and take care of leaks that may be increasing the quantity of water that is being sent to the septic system without your knowledge.
Last but not least, pay close attention to the water that enters your system.
For example, water should not be allowed to run straight into the septic system from a basement sump pump. Gutter, ditch, and other drainage systems should not be allowed to run into the area surrounding your drainage field.
How Much Distance Should Be Between My Septic Tank and My Well?
EPA and the Department of Housing and Urban Development suggest that a septic tank be located at least 50 feet away from a well that is used to provide drinking water. This is also a requirement for loans sponsored by the Federal Housing Administration, or FHA, however exceptions can be made in certain circumstances. The Code of Maryland Regulationsrequires specified spacing between septic components and wells, which we discuss in further detail in the next section.
Recommended Distances Between WellsSeptic Components
As a result of local rules or soil conditions, local authorities may mandate greater distances between a well and a septic component than those suggested by the Environmental Protection Agency. When property limitations or elevation changes are involved, components can be brought closer together in other circumstances. The following are the regulations for distances between wells and septic components in the state of Maryland for wells that are intended for water distribution: d) 100 feet from identifiable sources of contamination and designated subsurface sewage disposal areas if the proposed well will utilize an unconfined aquifer as a water supply source; e) 50 feet from identifiable sources of contamination and designated subsurface sewage disposal areas if the proposed well will utilize a confined aquifer as a water supply source; and f) 50 feet from any sewage gravity or force main, except as provided in B(3) of this regulation.
The Maryland Department of the Environment’s Regulation of Water Supply, Sewage Disposal, and Solid Waste, Chapter 04: Well Construction, is the source for this information.
Possible Contaminants from Septic Systems
When a well is located too close to a septic system or other source of wastewater, a range of pollutants, such as the following, might infiltrate your well water:
- Salmonella and E. coli are examples of bactria. Viruses, such as norovirus or hepatitis A
- Bacteria
- And parasites detergents and soaps that include phosphorus. Chemicals derived from paint, drain cleaners, and other common home items
- Heavy metals, iron, and copper are examples of such materials.
These pollutants, when present in large quantities, can cause illnesses or disorders. If you have reason to believe that your well has been polluted, it is critical that you have your water tested as quickly as possible. If a problem is discovered, water treatment techniques such as chlorination, reverse osmosis, activated charcoal filtration, or ultraviolet light purification may be able to restore your water to a safe drinking temperature. If this is not the case, it may be essential to make repairs to the well or septic system.

When Do You Need an Alternative Septic System?
The functionality of your home’s plumbing system is dependent on the efficiency of your septic system. Septic systems are responsible for collecting, storing, and treating waste in places where there is no access to a municipal sewage system. A standard septic system is comprised of two parts: a tank and a drain field (or field). In addition to holding trash, the tank also allows for the separation of solids from liquids. Water that has been treated is discharged into the drain field through a network of perforated pipes.
- While a traditional septic system is the most frequent type of septic system seen in residential settings, not all properties are excellent candidates for a system built in this manner.
- Water Tables that are extremely high In some regions, the water table can shift dramatically.
- In places with a high water table, the soil has already reached its maximum saturation point.
- Due to a high water table in the drain field, the saturation level of the soil in the drain field might become too high, making it hard for the soil to absorb the wastewater that is being discharged from the septic tank.
- A sand filtration system is the most prevalent form of filtration system that is employed.
- The sand will assist in the removal of any contaminants, resulting in cleaner water as it enters the drainage field.
- Soil with a shallow depth When it comes to septic systems, the depth of the soil on your land might influence which kind is most appropriate for your home.
If the topsoil levels on your land are very low, you may not be able to completely bury your septic tank in order to prevent flooding.
Homeowners with little soil depth can benefit from low-pressure pipe septic systems, which are a suitable septic option for them.
As an alternative to continuously releasing wastewater into the drain field, the pumping chamber is designed to release wastewater according to a predetermined schedule.
Soil that is impermeable It is not only soil depth that may have an impact on drain field performance; the kind of soil on your property can also have an impact on the efficacy of your septic system and should be taken into consideration.
A tight crust forms on the surface of clay-rich soils, which inhibits water from penetrating the soil.
These septic systems are distinguished by the presence of a drain field that is located above ground level.
The last stage is to cover the entire region with permeable sand, which will enable for adequate wastewater treatment to take place.
Regular cleaning and repair of your septic system are essential, regardless of the type of system that serves your property. Get in touch with Pete’s Outflow Technicians immediately to arrange for a septic tank and line cleaning for your system.
Septic Systems and Surface Water
1. Bathrooms and Kitchens | Wastewater from toilets, sinks, showers, and other appliances contains harmful bacteria, viruses, and nutrients that could contaminate nearby surface water sources. You can help reduce the amount of nutrients in your wastewater by limiting use of the garbage disposal and using phosphate-free detergents. Avoid flushing other chemicals or medications down the drain or toilet since they could also contaminate surface water sources. | |
2. Septic Tank | Wastewater generated in your home exits through a drainage pipe and into a septic tank. The septic tank is a buried, water-tight container that holds wastewater for separation and treatment. The solids settle to the bottom (sludge) and fats, oil and grease float to the top (scum). Microorganisms act to break down the sludge and destroy some of the contaminants in the wastewater. Your septic tank should be serviced and pumped on a regular basis to make sure it’s working properly. | Learn more about how your septic system works. |
3. Drainfield | The drainfield is a shallow, covered trench made in the soil in your yard. Partially treated wastewater from the septic tank flows out through the drainfield, filters down through the soil and enters the groundwater. If the drainfield is overloaded with too much liquid or clogged with solids, it will flood and cause sewage to surface in your yard or back up into your home. | Learn more about maintaining your drainfield. |
4. Wastewater Treatment in Soil | Filtering wastewater through the soil removes most bacteria and viruses (also known as pathogens) and some nutrients. While soil can treat many contaminants, it cannot remove all of them (e.g., medicines, cleaning products, other potentially harmful chemicals). If untreated wastewater surfaces in the yard, wastewater may contaminate the streams, lakes, or coastal waters near your home. Avoid putting chemicals or medications down the drain or toilet since they could end up in surface waters too. | Learn more about sources of and solutions to nutrient pollution.Learn more about preventing eutrophication. |
5. Water Table | The water table is where you first hit water if you dig a hole into the ground. | |
6. Groundwater | The water below the water table is called groundwater. Groundwater flowing underneath a drainfield captures any remaining contaminants released from the septic system. A stream, lake, or coastal water is at greater risk of becoming contaminated if it is in the path of groundwater flow beneath the septic system. | Learn more about getting up to speed with protecting groundwater. |
7. Nutrients in Surface Water (Nitrogen, Phosphorus) | When there are too many nutrients in surface water, they act as a fertilizer for fast-growing bacteria and algae. This rapid growth can cause algal blooms that can reduce water quality, kill aquatic animals and plants, and form toxins in the water. This process is called eutrophication. Harmful algal blooms (HABs) in lakes and streams can be toxic to humans and animals.Phosphorus: Depending on your soil type, phosphorus from wastewater can be absorbed and retained in the soil. Unabsorbed phosphorus can travel in groundwater toward a waterbody and become a source of contamination. Freshwater is more vulnerable to phosphorus pollution.Nitrogen: Some nitrogen may be removed as wastewater flows through the septic system and soil. But the remaining nitrogen can enter the underlying groundwater and flow towards a surface water body. If there are many septic systems in a small area, the nitrogen flowing through groundwater could overload a waterbody, causing eutrophication. Saltwater is more vulnerable to nitrogen pollution. | Learn more about harmful algal blooms and cyanobacteria. |
8. Setback Distance | Most states or local governments require a specific horizontal distance (or setback) between a septic system and surface water bodies. If the soil where you live is sandy, or porous, you may want to place your septic system farther away than the minimum required distance. Contamination is less likely the farther away your septic system is from a body of water. | Consult your local health department about required setback distances in your area. |
9. Streams, Lakes and Coastal Waters | Groundwater and surface water runoff flows into streams, lakes, and coastal waters. If this water contains contaminants, they can make their way into surface waters, causing eutrophication (see7). It’s important to keep surface waters healthy to use for recreation, fishing, and as a drinking water source. | Learn more about the environmental problem of nutrient pollution.Learn more about the effects of nutrient pollution. |
Septic Systems and Drinking Water
1. Bathrooms and Kitchens | Water from toilets, sinks, showers, and other appliances is called wastewater and can be harmful to human health. Wastewater contains harmful bacteria, viruses, and nutrients that could make you sick if it comes in contact with your drinking water well. Make sure the wastewater is properly treated by your septic system and that your drinking water well is located at the appropriate distance (set back) from your and your neighbor’s system. Avoid flushing other chemicals or medications down the drain or toilet since they could also contaminate your drinking water well. | |
2. Septic Tank | Wastewater generated in your home exits through a drainage pipe and into a septic tank. The septic tank is a buried, water-tight container that holds wastewater for separation and treatment. The solids settle to the bottom (sludge) and fats, oil and grease float to the top (scum). Microorganisms act to break down the sludge and destroy some of the contaminants in the wastewater. Your septic tank should be serviced and pumped on a regular basis to make sure it’s working properly. | Learn more about how your septic system works. |
3. Drainfield | The drainfield is a shallow, covered trench made in the soil in your yard. Partially treated wastewater from the septic tank flows out through the drainfield, filters down through the soil and enters the groundwater. If the drainfield is overloaded with too much liquid or clogged with solids, it will flood and cause sewage to surface in your yard or back up into your home. | |
4. Wastewater Treatment in Soil | Filtering wastewater through the soil removes most bacteria and viruses (also known as pathogens) and some nutrients. While soil can treat many contaminants, it cannot remove all of them (e.g., medicines, some cleaning products, other potentially harmful chemicals). If untreated wastewater surfaces in the yard, wastewater may contaminate your drinking water through an unsecured well cap or cracks in the well casing. It’s important to avoid flushing medication and chemicals into your wastewater since it could contaminate your drinking water. | |
5. Water Table | The water table is found where you first hit water if you dig a hole into the ground. | |
6. Groundwater | The water below the water table is called groundwater. Groundwater flowing underneath a drainfield captures any remaining contaminants released from the septic system. A drinking water well is at greater risk of becoming contaminated if it is in the path of groundwater flow beneath a septic system. | |
7. Drinking Water Well | A drinking water well is drilled or dug into the groundwater so water can be pumped to the surface. Deep wells located farther away from a septic system and not in the path of the groundwater flow from the septic system are least likely to be contaminated. Drinking water wells should be regularly tested to ensure your home’s water is safe to drink. | Learn about private water wells. |
8. Setback Distance | Most states or local governments require a specific horizontal distance (or setback) between a septic system and a drinking water well. If the soil where you live is sandy, or porous, you may want to place your well farther away than the minimum required distance. Contamination is less likely the farther apart a well is from a septic system. | Consult your local health department about required setback distances in your area. |
9. Could my well be affected? | Your septic system could contaminate your drinking water well or a nearby well under certain conditions. Remember to test the drinking water from your well regularly and take corrective action as needed.The contamination risk to your well is LOWER: |
- The greater the distance between the well and the septic system
- The greater the depth of the well and whether it is on bedrock or below a specified layer of silt or clay
- And the greater the distance between the well and the septic system If your septic system is pumped and maintained on a regular basis, you can avoid this.
The following factors increase the danger of pollution to your well:
- The well is at a shallow depth and in permeable soil
- It is downgradient of the septic system (i.e., groundwater flows from the septic system towards the well)
- There are many homes on septic systems near the well
- Or the well and/or septic system have been poorly constructed or maintained (i.e., contaminants can enter a cracked drinking well casing from groundwater or surface water).
Learn other ways to keep your private well safe from possible sources of contamination. |
Septic System Design for High Water Table
Designing a Septic System for a High Water Table LES LIE: Richard in North Dakota is on the phone, and he’s having a septic problem. It’s a terrible sounding phrase. Please explain what is going on. I’m not going to sugarcoat it. TOM: Hello there, Richard. When the water table rises to a dangerously high level, as it usually does around this time of year and continues through the end of May, the septic tank just overflows and my leach shield becomes clogged. TOM: Oh, my God. RICHARD: And I’m not sure what the best method would be to – I was thinking of putting a back-water valve in, but I’m not sure how to place it correctly so that it would really work.
- Because you can’t possibly be the only person who has this problem.
- We’ve talked to another neighbor, and it appears like we’re the only ones in the neighborhood that are experiencing this problem.
- And all of the area in our immediate vicinity is agricultural.
- TOM: As a result, when the water table is low, the septic field is in good working order.
- RICHARD: That’s correct.
- You know, it’s likely that things have always been this way.
- RICHARD: No, I don’t think so.
In order to prevent this from happening, I walk into the basement and insert a plug into the floor drain, after which I insert a plug into the shower.
As a result, you just do not utilize the downstairs.
If you take any of those out, the water will flood out.
And it’s done purposefully; there’s a certain amount of engineering involved in determining the exact strata that will be included into the mound itself.
But, you know, it kind of looks like rolling fields when it’s finished, but it actually raises the elevation.
However, it appears to me that you do not have a great deal of alternatives in this situation.
My opinion is that you will have no choice but to use a mounded system or some form of constructed system.
I was thinking about doing something similar to that, except instead of merely a mound, I was planning on building a retaining wall that was four feet high.
TOM: In addition, new systems are constantly being introduced to the market that employ some form of open or aerobic treatment system that is exposed to the elements in an open configuration.
However, when dealing with a high water table, a mounded system is almost always the best answer to the problem.
Thank you for confirming my worst fears, at least for now.
Sorry for being the bearer of terrible news, but this is the only way to put an end to this situation once and for all.
Having a system that only works half the year means you’ll probably be locked in that location for the foreseeable future. RICHARD: That’s right. And then they really stated that the refinery was the reason why it was so inexpensive to produce. TOM: That’s right. Alright. Best of luck.
How a Septic System Works – and Common Problems
This Article Discusses Septic Tanks are a type of septic tank that is used to dispose of waste. Field Sizing and System MaintenanceProblems with the Leach FieldSystem Performance Questions and comments are welcome. See Also: Septic System Frequently Asked Questions Articles on SEPTIC SYSTEM may be found here. In locations where there are no municipal sewage systems, each residence is responsible for treating its own sewage on its own property, which is known as a “on-site sewage disposal system,” or septic system, more popularly.
One of the most commonly seen types of leach field is composed of a series of perforated distribution pipes, each of which is placed in a gravel-filled absorption trench.
SEPTIC TANK
The wastewater is collected in the septic tank once it has been discharged from the residence. Septic tanks are normally between 1,000 and 2,000 gallons in capacity and are composed of concrete, strong plastic, or metal, depending on the model. Highly durable concrete tanks, which should endure for 40 years or more provided they are not damaged, are the most common. Many contemporary tanks are designed with two chambers in order to maximize efficiency. Household wastewater is collected in the septic tank, where it is separated and begins to degrade before being discharged into the leach field.
- In the tank, oil and grease float to the top of the tank, where they are known as scum, while solid waste falls to the bottom, where they are known as sludge.
- Bacteria and other microorganisms feed on the sediments at the bottom of the tank, causing them to decompose in an anaerobic (without oxygen) process that begins at the bottom of the tank.
- Solids and grease must be pushed out of the system on a regular basis in order for it to continue to function effectively.
- Each gallon added to the tank results in one gallon being discharged to the leach field, leach pit, or other similar treatment facility.
A large amount of water delivered too rapidly to the tank may discharge untreated effluent, along with oil and particulates, into the leach field, where it may block the field and cause a backup.
Leach Field
When used properly, a leach field (also known as a “drain field”) is a series of perforated pipes that are typically buried in gravel trenches 18 to 36 inches below grade — deep enough to avoid freezing, but close enough to the surface that air can reach the bacteria that further purify the effluent (see illustration below). As little as 6 inches might separate you from the ground surface, depending on your soil type and municipal regulations. It is customary to cover the perforated pipes with approximately two inches of gravel and a layer of topsoil that is 18 to 24 inches in depth.
- Grass is often sown above the ground.
- The leach field is comprised of rows of perforated pipes in gravel trenches that are used to spread wastewater over a vast area in order to further purify it.
- A bacteria-rich slime mat forms where the gravel meets the soil, and it is responsible for the majority of the water purification work.
- Despite the fact that wastewater freezes at a far lower temperature than pure water, freezing is still a hazard in cold areas.
- The leftover pathogens are converted into essential plant nutrients by these organisms, while sand, gravel, and soil filter out any solids that remain.
- If the system is operating effectively, the filtered wastewater will return to the aquifer as naturally clean water that is suitable for human consumption at this stage.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
- Special systems may also be necessary in regions where there are flood plains, bodies of water, or other ecologically sensitive areas to protect against flooding.
SIZING THE LEACH FIELD
Using perforated pipes put in gravel-filled trenches, the drain field is sized to accommodate the number of beds in the house. In order for the system to function successfully, the leach field must be appropriately sized for the soil type and amount of wastewater, which is normally determined by the number of bedrooms in the house. In order for the liquid to seep into the soil, it must be permeable enough to do so. As a result, the denser the soil, the larger the leach field that is necessary.
- Better to have surplus capacity in your system than to have it cut too close to the bone.
- Septic tank backup into your house, pooling on the surface of the earth, or polluting local groundwater are all possibilities if the ground is incapable of absorbing the liquid.
- Dense clay soils will not absorb the liquid at a sufficient rate, resulting in a backlog.
- If the soil is mostly composed of coarse sand and gravel, it might drain at such a rapid rate that untreated sewage can poison the aquifer or damage surrounding bodies of water.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
These systems sometimes cost twice or three times as much as a regular system and require significantly more upkeep. Near flood plains, bodies of water, and other ecologically sensitive places, special systems may also be necessary to protect people and property.
SEPTIC SYSTEM CAREMAINTENANCE REQUIRED
If you take good care of your system, you will be rewarded with years of trouble-free operation. Pumping the septic tank on a regular basis is necessary to remove the particles (sludge) and grease layer (scum) that have built up in the tank. The solids will ultimately overflow and spill into the leach field, decreasing its efficacy and diminishing its lifespan if this is not done. The rehabilitation of a clogged leach field is difficult, if not impossible; thus, constant pumping is essential!
- Cooking fats, grease, and particles may also wash into the leach field if the tank is too small for the amount of water being used or if the tank is overcrowded on a regular basis.
- Extra water from excessive residential consumption or yard drainage can overwhelm the system, transporting oil and particles into the leach field and causing it to overflow.
- In addition, don’t try to complete a week’s worth of laundry for a family of five in a single day.
- To minimize overburdening the system, the following measures should be taken:
- Distribute your washing loads and other high-water-use activities across the week
- And In the kitchen and bathroom, use low-flow appliances, faucets, and fixtures. Toilets, in general, are the source of the greatest amount of water use. Water should be diverted away from the leach field from the yard, gutters, and basement sump pumps.
In addition, refrain from flushing sediments, strong chemicals, and just about anything else down the toilet or sink other than biological waste and white toilet paper. Avoid using garbage disposals in the kitchen. If you really must have one, keep it for small non-meat bits only. Avoid flushing chemicals or paints down the toilet since many chemicals can destroy beneficial microorganisms or cause water contamination in the surrounding area. Avoid flushing the following down the toilet:
- Grease, fats, and animal scraps
- Paints, thinners, chemicals, and pharmaceuticals
- And a variety of other materials sanitary napkins, tampons, and other supplies Paper towels and disposable diapers are examples of such products. Egg shells, coffee grounds, and nut shells are all good options. Antibacterial soaps and antibiotics are available.
It is preferable to put grass over the leach field and to refrain from driving or parking in the vicinity. Excessive weight placed on top of the drain field might compress the earth, diminishing its efficiency as a drain field. Drain pipes can also become clogged by trees and plants with invasive roots. In order to prevent damage to the leach field, the following measures should be taken:
- Heavy machinery should not be driven, parked, or stored on top of the leach field (or septic tank). Placement of a deck, patio, pool, or any other sort of construction over the leach field is prohibited. Remove any large trees or other plants with deep roots from the leach field. Grass is the most effective groundcover.
Even with careful use and routine maintenance, however, leach fields are not guaranteed to survive indefinitely. It is inevitable that the soil will get saturated with dissolved elements from the wastewater, and that the soil will be unable to absorb any more incoming water. The presence of an odorous wet area over the leach field, as well as plumbing backups in the house, are frequently the first indicators that something is wrong. Many municipalities mandate septic system designs to incorporate a second “reserve drain field” in the case that the first field fails.
A well constructed and maintained system should last for at least 20 to 30 years, if not longer than that. After a few tears, the initial field will naturally heal and may be used once again when the situation calls for it to be. More information on Septic System Maintenance may be found here.
SEPTIC SYSTEM PERFORMANCE PROBLEMS
Poor original design, abuse, or physical damage, such as driving heavy trucks over the leach field, are the root causes of the majority of septic system issues. The following are examples of common situations that might cause a septic system to operate poorly: Plumbing in the home. obstructed or insufficient plumbing vents, a blockage between the home and the septic tank, or an insufficient pitch in the sewer line leading from the house are all possible causes. Sewage tank to leach field connection Septic tank and leach field blockage caused by a closed or damaged tank outlet, a plugged line leading to the leach field caused by tree roots, or a blockage caused by sediments that overflowed from the tank Piping in the leach field.
- Most of the time, tree roots do not make their way through the gravel bed and into the perforated pipe.
- Reduced flows, achieved through the use of flow restrictors and low-flow faucets and fixtures, may be beneficial.
- Because of the seasonal high water table, the soil around the trenches might get saturated, reducing the soil’s ability to absorb wastewater.
- This may frequently be remedied by adding subsurface drains or curtain drains to intercept the water flow into the leach field region and to lower the water table in the immediate area around the drainage system.

4 Things to Do When Your Septic Tank Is Flooded
If your neighborhood has recently been flooded or has been subjected to strong rains, you may discover that your toilet isn’t flushing properly and that your drains are draining more slowly than usual. It is possible that raw sewage will back up into your tub and sink drains. Drains that are slow or clogged may signal that the water table has risen over the level of your septic field and septic tank. If you believe that your septic system has been flooded, there are four things you should do immediately.
- Check the level of groundwater in your area.
- Septic tanks are typically located a few feet below the surface of the earth.
- If you are aware of the location of your septic tank and drainfield, you should check the water level in the area to ensure that flooding is not a concern.
- When there isn’t any evident standing water in the area, use a probe to check the water level or an auger to dig deep into the earth to find out how much water is there.
- If your tests reveal that the water level is higher than the top of the septic tank, you should immediately cease utilizing the tank.
- 2.
- Until the Ground Becomes Dry When you believe that your septic system has been flooded, contact a septic pumping specialist immediately; however, you must wait until the earth has become less soggy before having your tank drained.
- If a septic tank is pumped out when the earth is saturated, it may potentially float out of its location.
- Following a decrease in the water table level, it is necessary to pump your system as quickly as feasible.
- 3.
- Approximately 70 gallons of water are flushed down the toilet per person every day in the average home.
The first step is to check for leaks in all of your fixtures. An inoperable toilet flapper or fill mechanism can leak up to 200 gallons per day, creating a backup of water that your flooded septic system doesn’t have room for. Other suggestions for keeping water out of the drains are as follows:
- Prepare meals that don’t require cooking, such as sandwiches. Disposable flatware, such as paper plates and paper cups, should be used. Showers are preferable to baths because they are shorter. Save the rinse water and put it to good use on the plants. Only flush the toilet when absolutely essential
If your clothes washing machine drains into your main sewage line, it can cause a significant amount of water to be discharged into your septic system. Wash your garments at the laundry until the water table begins to fall below the surface. In the event that you must use the washing machine, wash only modest loads and wait a few hours between each load of laundry. 4. Make modifications to your septic system to make it more efficient. After your septic tank has been drained and your house drainage system has been restored to working order, you should make certain modifications to your system in order to minimize flooding problems in the future.
During a septic emergency, the backflow preventer prevents waste water from entering your home or building.
Also, check to be that your yard’s storm drainage does not overflow into your septic field and storage tank area.

Tips For Installing A Septic System Despite A High Water Table – Tidying Up Your Workspace
If your house was constructed outside the boundaries of the city sewage system, you will be required to have a septic tank installed in order to use the plumbing. Septic systems provide a full waste management system that is contained within your property, but they are not without their own set of difficulties. If your property, for example, has a high water table, there are several things you should be aware of. What is the impact of a high water table on my septic system? Underground septic systems are comprised of a big tank and a drain field that is connected to it.
- During the functioning of your septic system, the drain field must be able to absorb and filter the waste water in order to function effectively.
- Because a high water table can actually interfere with the ability of the top soil layer to collect and process waste water, it is important to keep your water table under control.
- Is it still possible to have a septic system if the water table is high?
- To the contrary, if you speak with a septic system specialist about your worries, he or she will be able to assist you in making adjustments to your plan to account for the potential water table issues.
- For example, if you enjoy entertaining, consider how many people you regularly invite over to your home.
- Additionally, you’ll want to make certain that the tank is large enough, and you’ll want the system pumped more regularly than the manufacturer’s recommended.
- This will limit the likelihood of anything leaking into the drain field and causing oversaturation of the soil.
- If you want to filter out the majority of the impurities, you might consider installing a recirculating sand fill unit in your system.
- This type of equipment will filter waste water through sand numerous times in an attempt to remove pollutants and particles.

Strander’s Sanitary FAQ
Septic systems are believed to be on-site systems that are meant to dispose of biological sanitary waste in a safe and proper manner. Even though “gray water,” such as laundry waste, is a component of the waste system, it does not always result in what is referred to as “biological” waste. We will discuss the issue of “gray water” waste and how it affects the design of a septic system in this section.
How Do Septic Systems Work?
Essentially, a septic system serves as a “holding tank” in which natural bacterial action decomposes human waste products into environmentally acceptable components, with water as the primary end-component, mixed with some other components that are not readily consumed by the bacterial action, gases, and undigested solids as minor end-components. With the exception of the undigested solids, the final products are released into the on-site environmental environment.
Where Are The Septic System Components Located?
The septic tank, which is usually made of concrete or steel, is buried in the ground at a distance of at least 10 feet from the house. The top of the tank is usually about one foot below the surface of the soil, allowing it to be opened for inspection and pumping on a regular schedule. If you are unsure of the location of the tank, the first step is to identify the point at which the house sewer pipe exits the house. If you live in a house with a basement, here is where the pipe enters the house from the outside.
- If the pipe exit can be discovered, the tank generally begins around 10 feet from the home exterior wall and in line with the house sewer pipe.
- For a few bucks, you can pick up a metal rod with a diameter of around 1/8 inch from most hardware stores.
- The distribution box is significantly smaller than the septic tank and is normally situated approximately 20 feet from the home.
- Again, you can probe the soil carefully to identify the distribution box with a narrow metal rod.
- The pipes in the trenches have holes in them to allow the liquid to be equally dispersed inside the trench.
- Above the stone is a soil filter (usually one or two layers of what is called untreated building paper) (usually one or two layers of what is called untreated building paper).
- Equally important is WHERE THE COMPONENTS SHOULD NOT BE.
- In some areas, the well is not allowed to be down-slope from the leach field.
- Normally, no part of the system should be within 10 feet of a property line.
In some areas and in unusual conditions, minimum distances may be greater than those noted here. In addition, no part of the system should be under a porch or driveway and you should not drive heavy vehicles (including automobiles) over the system lest the system be damaged.
Care and Maintenance of A Septic System
Conventional septic systems are not without their own set of problems. Pumping out the undigested solids (sludge) that accumulate at the bottom of the septic tank should be done every 2 to 3 years, depending on the amount of usage and size of the tank. It is inevitable that sludge will accumulate in the leach field over time and cause the field to collapse if it is not cleared on a regular basis. Using excessive amounts of common home chemicals such as drain cleansers, laundry detergent, and bleach may be harmful to a well-designed system since they can clog the system.
Fatty foods and oil used in the kitchen should be avoided.
Why Septic Systems Fail
The sewage system may back up and overflow into the home or puddle on the surface of the ground if the liquid effluent does not have time to soak into the soil around the leach field before it becomes stagnant. Several different factors might be contributing to this issue. Poor soil conditions; faulty design or installation are examples of this. A leaching system installed in inappropriate soil, a system that is too small for the house it serves, or a system that has been incorrectly designed can all result in premature failure of the system.
- Clogging of the soil It is very likely that the soil will become blocked very rapidly if sludge or scum is allowed to escape into the distribution box and then onto the leach field.
- This problem can be caused by septic tank baffles that have been damaged, allowing sludge or scum to seep into the surrounding area.
- 3.
- This situation may need the reinstallation of the system at a more advanced level.
- 4.
- In most cases, the plants must be removed and the roots must be removed from the pipes.
- You should be aware of the system’s position and direct traffic in order to avoid causing harm to the system.
How Long Should A Septic System Last?
A standard septic system, such as the one detailed here, may be expected to survive for around 30 years before needing replacement. Other systems persist far longer than others, and some systems fail considerably more quickly than others for a variety of causes, including those listed above. Other factors might also have an impact on the lifespan of a septic system. For example, a system that had been giving excellent service to a prior owner for many years may suddenly stop working shortly after you purchase the property.
If the previous owners were a working couple with no children, it is likely that the system was not extensively utilized; if your family is a large one, the additional load may be enough to push a mediocre system over the edge and cause it to malfunction.
What is Gray Water?
In most cases, gray water comes from a laundry system, but it can also come from a sump pump, foundation footing drains, roof runoff, and sometimes shower drains, as well as other sources. This water typically does not include any human waste products and hence does not require digestion in the same way that human waste does. The criteria for disposing of this sort of water are less strict than those for disposing of human waste. If you have a limited amount of available space on your property, it may be feasible to separate the gray trash from the human waste and reduce the size of the system required to regulate the human waste to save costs.
What are the Signs of a Failing System?
The backup of sewage into the residence is one indication that the system is malfunctioning. Backup, on the other hand, can simply be the consequence of a blockage somewhere between the home and the septic tank, as was the case in this case (this is relatively easy to fix). Another symptom of failure might be the stench of sewage emanating from outside the house. The presence of this scent after a significant amount of water has been poured into the system – many showers or several loads of laundry (if the laundry waste discharges into the septic system), for example – may be an indicator that the leach field is not functioning properly.
- If water and garbage are being pushed to or near ground level, this might give the surface a “spongy” sensation.
- The source of this odor, on the other hand, may be the plumbing vent.
- If you see any of these indicators, a dye test may be performed to validate your concerns.
- After then, a substantial volume of water is flushed through the system.
- It would be a very strong indicator that the system had failed if the dye could be visible on the surface.
I Plan on Repairing, Installing or Replacing a System. What Should I Expect?
When it comes to installing a new system or repairing or replacing an old one, there are two key considerations. It is first and foremost a financial burden, and second, the inconvenience of maybe being unable to utilize the present system while a new system is being built. When it comes to new building, the second aspect is typically not a significant concern. The cost of repair or replacement will, of course, vary depending on what has to be repaired or replaced. If the repair does not include the leach field, the cost may be significant, but it is not likely to be prohibitively expensive in comparison.
It is estimated that this sort of repair will cost in the neighborhood of several hundred dollars.
You should budget an additional $2000 to $3000 for a typical home if a new leach field is required and there is enough space to accommodate the installation.
Where a new leach field cannot be constructed because there is insufficient space, the present field, including the congested soil, must be demolished and a fully new system constructed. Such an undertaking can easily cost in excess of $10,000.
Alternative (Other Types of) Systems?
In the last section, we covered a conventional system that was put in the soil that already existed on the site. When the site circumstances do not permit the installation of this sort of system, there are other options available to consider. A “mound” system, for example, may be used when groundwater or percolation rates are insufficient or inappropriate for the situation. A mound system is one in which a suitable soil is put on top of an unsuitable soil. Following that, a typical system is placed in the mound.
- There may be an option to install one or more cesspools, also known as seepage pits, if there isn’t enough space for a normal leach field to be constructed.
- For these systems, once again, there are special needs to meet.
- This indicates that the bacteria are able to function without the presence of oxygen.
- There are also hybrid systems, which employ a combination of anerobic and aerobic parts to get the desired results.

Application Rate / Flow Rate (gallons per day) equals the required area (in square feet) (gallons per day per square foot) Now that we know the number of square feet of absorption field that will be required, we can divide that amount by the width of each trench to get the number of feet of trench that will be needed.
- Let’s have a look at an example computation to understand how it all works.
- There has been a failure in the leach field, and a new one must be erected.
- What is the size of the absorption field that will be required?
- According to the data above, the application rate is 0.5 gallons per day per square foot, with a percolation rate of 32 minutes per inch, and the percolation rate is 32 minutes per inch.
- You will require a total of 900 square feet of absorption space.
- A lateral is a trench that is no longer than 60 feet in length.
- It is preferable to have the laterals the same length wherever possible, thus your design professional may specify eight laterals, each of which is 60 feet long, when the property conditions allow.
It is necessary to dig ten trenches, which are known as laterals. Additionally, you should provide for the possibility of future development in addition to the requisite space for the leach field (50 percent expansion area is required in New York State).
What Are the Components of a Private Spectic System?
Everything that is most evident is the stuff that we see every day: the sinks, toilets, and pipes found in a typical home, for example. What is not apparent are the things that are underground; the items that are underground, as well as the earth itself, have a significant influence on the way a septic system functions and functions well. The septic tank, a distribution box, and a leach field are the three main components of the system, respectively. Bacterial action occurs in the septic tank, where the end products are mostly water, gases, and undigested material, which is referred to as sludge, which sinks to the bottom of the tank and scum, which floats to the top of the tank, respectively.
- By using the plumbing vent system, the gases that are produced may be released into the atmosphere.
- These perforated pipes then transport the liquid to a vast area of soil surface known as a leach field or absorption field, where it may be absorbed.
- The sludge that accumulates at the bottom of the tank must be drained out and properly disposed of on a regular basis.
- This sort of system is the subject of the following discussion.
If my Family is Growing and I add a New Bedroom, What Should I Expect?
Septic systems are designed to handle the disposal of biological waste generated in the home. The amount of garbage that must be managed is determined by a variety of factors. The number of people who live in the house, as well as their way of life, are among the considerations. After many years of research and development, it has been discovered that the number of bedrooms in a house is a significant guideline in deciding the size and functionality of a septic system. As a rule, the number of bedrooms is proportional to the number of people who generate trash and, consequently, the amount of rubbish that must be managed.
Failure of the septic system may occur if the system’s capacity cannot keep up with the rising demand for services.
The following parts are mostly concerned with the proper size of a septic system in order for it to accomplish its intended function.
Although you may not require all of this information, it may be useful in making your selections.
