A septic system contains an underground septic tank made of plastic, concrete, fiberglass, or other material to treat and dispose of sewage. This system is designed to provide an individualized wastewater treatment option for commercial and residential areas.
How far should a septic tank be from a drainage system?
- Drainfields, soakbeds, soil absorption systems above high water tables need to have a minimum distance from a septic tank of about 4 or 5 feet to 10 feet or more.
What are three factors you should consider when installing a septic tank?
Here are factors to consider before you install a septic tank.
- Authorization. You must have a permit to install a septic tank on your property.
- Type. With the advancement of technology, you have diverse types of septic tanks to consider.
- Soil Type.
How far should a septic tank be from a house?
Most importantly, a septic tank must be at least seven metres from a house, defined as a ‘habitable property’. Septic tanks are built underground and release wastewater slowly into the surrounding environment. For this reason, they must be a set distance away from a home.
What are the new rules on septic tanks?
According to new regulations passed in 2015, if your septic tank discharges to surface water such as a ditch, stream, canal or river, you will have to upgrade your system to a sewage treatment plant or install a soakaway system by 1 January 2020.
What to know about having a septic tank?
The septic tank is a buried, watertight container typically made of concrete, fiberglass, or polyethylene. It holds the wastewater long enough to allow solids to settle out (form- ing sludge) and oil and grease to float to the surface (as scum). It also allows partial decomposition of the solid materials.
Where should a septic tank be placed?
Northwest is the best direction for installing a septic tank. It doesn’t matter if your house is east or west-facing, as the direction of your house does not take into account the position of the septic tank. Therefore, septic tank location as per Vastu must always be in the northwest part of your home.
How do I decide where to put my septic tank?
Ideally, a septic tank should be placed on level ground. If possible, the tank should be placed on high ground in order to avoid flooding and seeping. It will be important that you look around and avoid steep slopes or areas of dense tree roots that can damage your entire system.
Why do I smell my septic tank when it rains?
Raining often causes atmospheric pressure changes, which can lead to the air becoming heavy. As such, the methane gases typically found in the septic tank don’t flow through the vent as they normally would. Instead, they stay low to the ground, causing a foul smell similar to rotten eggs.
Is planning permission required for septic tank?
The short answer is yes. You will need planning permission from a local authority in order to have a septic tank installed, no matter if it’s at your own home or on a business site.
Can I build a deck over my septic tank?
You should never build a deck over a septic field; doing so will prevent the natural draining and dissipation of the effluent. This can ruin the septic system, not to mention releasing foul smells into the air all around your deck. The dissipating effluent can also rot the deck from underneath.
Are septic tanks still legal?
Septic Tanks Explained… Septic tanks cannot discharge to surface water drains, rivers, canals, ditches, streams or any other type of waterway. you are required to upgrade or replace your septic tank treatment system to a full sewage treatment plant by 2020, or when you sell a property, if it’s prior to this date.
What are the do’s and don’ts of a septic tank?
DON’T flush material that will not easily decompose, such as hair, diapers, cigarette butts, matches, or feminine hygiene products. DO conserve water to avoid overloading the system. They kill the bacteria needed to decompose wastes in the septic tank and drain field. DO use substitutes for household hazardous waste.
Does heavy rain affect septic tank?
It is common to have a septic back up after or even during a heavy rain. Significant rainfall can quickly flood the ground around the soil absorption area (drainfield) leaving it saturated, making it impossible for water to flow out of your septic system.
How do septic tanks look?
Septic tanks are typically rectangular in shape and measure approximately 5 feet by 8 feet. In most cases, septic tank components including the lid, are buried between 4 inches and 4 feet underground. You can use a metal probe to locate its edges and mark the perimeter.
How long do septic tanks last?
A septic system’s lifespan should be anywhere from 15 to 40 years. How long the system lasts depends on a number of factors, including construction material, soil acidity, water table, maintenance practices, and several others.
Does shower water go into septic tank?
From your house to the tank: Most, but not all, septic systems operate via gravity to the septic tank. Each time a toilet is flushed, water is turned on or you take a shower, the water and waste flows via gravity through the plumbing system in your house and ends up in the septic tank.

Regulations Governing Septic Tank Design
Using the New York State wastewater treatment standard for individual household septic systems (Appendix 75-A), this document illustrates how state regulations govern the design and installation of both conventional tank and leach field septic systems and alternative septic system designs, such as raised septic systems, septic mound systems, intermittent sand filter systems, and evaportion-transpiration septic systems, among other things.
Date of Inception:12/01/1990 Appendix 75-A.6 – Appendices
(a) General information about Septic Tank Design
(1)The capacity of a septic tank must be determined by the number of bedrooms in the family. An extension attic will be treated as if it were a second bedroom in the house. Table 3 outlines the minimum septic tank capacity as well as the minimum liquid surface areas that must be met.
Table 3: Minimum Septic Tank CapacitiesProperties Based on Number of Bedrooms
|Number of Bedrooms||Septic Tank Size (Gallons)||Minimum Liquid Surface Area (Sq.Ft.)|
|1, 2, or 3||1000||27|
Notes to the Table Above
When there are more than six bedrooms, the septic tank capacity requirements should be determined by multiplying the number of bedrooms by 250 gallons and seven square feet of surface area for each additional bedroom. The use of a trash grinder will be treated as if it were an additional bedroom when evaluating the size of the tank. A comprehensive chart of septic tank size requirements, as well as techniques for estimating septic tank size, may be found on a separate page, SEPTIC TANK SIZE (2) Septic tank lids must be easily accessible at all times.
Extending collars must not be brought flush with the ground surface unless the cover can be fastened in place to prevent tampering with the installation.
(b) Design and Installation of Septic Tanks
The following is applicable to all septic tanks, regardless of their construction material. I A liquid depth of at least 30 inches is required. a tank’s design volume must be determined by measuring the depth of the tank to the maximum of 60 inches The addition of deeper tanks allows for more sludge storage, but no credit will be granted toward the design volume. (6feet) is the minimum distance between the intake and outflow of the system. All tanks must have a minimum surface area requirement for the specific design volume provided in Table 3 for the relevant design volume.
tanks must be waterproof, made of durable materials that are not susceptible to corrosion, decay, frost damage or cracking, and must not be vulnerable to corrosion, decay, frost damage, or cracking.
tanks with a liquid depth of 48 inches or more are required to have a topopening with a minimum length of 20 inches measured from its widest point to its smallest dimension to facilitate access into the tank.
(v) Tanks should be equipped with baffles, sanitary tees, or other measures at the inlet and outlet to prevent the passage of floating solids and to limit the disturbance of settled sludge and floating scum caused by sewage entering and exiting the tank.
In tanks with a liquid depth of less than 40 inches, inlet and outlet baffles must extend a minimum of 12 inches and 14 inches, respectively, below the liquid level; in tanks with a liquid depth of 40 inches or greater, inlet and outlet baffles must extend a minimum of 16 and 18 inches, respectively, below the liquid level.
- Baffles must be made of a long-lasting material that is resistant to corrosion, deterioration, and cracking, among other things.
- Tank systems with many chambers and tanks must be built to allow for the venting of tankgases as well.
- This will ensure that the leveling and bearing are correct.
- (viii) Between the inverts of the inlet and outflow pipes, there must be a minimum elevation difference of two inches.
- When a waste grinder may be reasonably predicted at the time of construction or in the future, an extra 250 gallons of capacity and seven square feet of surface area are required.
Additionally, a gas deflection baffle or other approved outlet modification, as well as a dual compartment tank or two tanks connected in series, must be installed.
(2) Design Specifications for Multi-compartment septic tanks or tanks in series.
In all tanks with an interior length of ten feet or more, dual compartments are recommended, and in all tanks with an interior length of less than ten feet, dual compartments are necessary. On the intake side of the first compartment or tank, 60 to 75% of the overall design capacity must be accounted for. (iii) The baffle dividing the compartments must be at least six inches above the invert of the outflow pipe and extend from the bottom of the tank. A four-inch vertical slot at least 18 inches wide, a six-inch elbow, or two 4-inch elbows positioned below the liquid level and one-third the distance between the invert of the outlet and the bottom of the tank should link each compartment.
A single pipe with a minimum diameter of four inches should be used to link tanks that are connected in series.
(3) Design Specifications for Concrete septic tanks
For septic tank construction, the concrete used must have a minimum compressive strength of 2,500 pounds per square inch (psi) after 28 days of curing. A maximum compressive strength of 3,000 pounds per square inch (psi) is suggested as a minimum. Wall thickness for concrete septic tanks must be at least three inches unless the design has been verified by a New York licensed professional engineer as meeting all applicable standards for thin-wall construction. All walls, both at the bottom and at the top, must be reinforced to provide support for 300 psi.
Joints below the liquid level must be examined for water tightness before backfilling.
(4) Design Specifications for Fiberglass and Polyethylene Septic Tanks
Septic tanks made of fiberglass or polyethylene (plastic) must also comply with the following extra requirements: In regions where the groundwater level can rise to the level of the bottom of the septic tank, fiberglass or polyethylene septic tanks are not permitted to be placed. For Fiberglass or polyethylene septic tanks, special attention must be given throughout the installation process, bedding the tank, and backfilling the tank in order to avoid damage to the tank walls. The installation instructions provided by the manufacturer must be followed.
Because of its size, the tank may be transported to the site in pieces.
(5) Design Specifications for Steel Septic Tanks
Steel septic tanks must be labeled to indicate that they are protected against corrosion in accordance with Underwriters Laboratories, Inc. Standard UL-70 or a similar standard.
(6) Design specifications for Aerobic Septic Septic Tanks or Aerobic Treatment Units (ATUs)
It is possible for a homeowner to choose to construct an aerobic unit rather than a septic tank under the following circumstances: In accordance with NSF Standard 40 or an equivalent, the aerobic treatment unit should be labeled to indicate that it complies with the specifications for a Class I unit as defined in the National Sanitation Foundation (NSF) Standard 40. (ii) The rated capacity of the aerobic treatment units must be equal to or greater than the design flow, as indicated by Table 1 of the specifications.
Aerobic treatment units that do not come with a service contract that includes, at the very least, semiannual inspections and annual pumping for a period of three years or more are not permitted to be sold.

Understanding Your Septic System
Knowing the basics of septic systems, whether you’re installing or living with one, is beneficial when making decisions about your home. If you follow these procedures, you will be able to extend the life of your system, learn what to do if something goes wrong, and analyze your alternatives if you ever need to expand your system due to a home renovation project. This type of sewage treatment system, which is utilized by one in every five households in the United States and almost half of all households in the South, cleans wastewater equally as well as municipal systems in cities.
When it comes to septic systems, the average life expectancy is 25 to 30 years.
How septic systems work
All septic systems are composed of two major components: a tank in which particles settle to the bottom and a drainfield (also known as a leachfield) in which water dissipates after passing through it. Detailed information regarding the sort of system you have should have been included in the documents you got when you purchased your home. If the specifics have become hazy due to the passage of time, get out those old documents and do some research. It’s possible that your local health department or state environmental agency has backup data as well.
According to typical septic systems, gravity moves wastewater from the home into the septic tank, which then transports it to a drainage field. The septic tank is a large underground container that is often built of concrete, polyethylene, or glass fiber. Water collects there for a long enough period of time for the components to separate. Every few years, a septic pumping firm will come in and remove the greases and oils that have risen to the surface as scum, as well as the solids that have sunk to the bottom as sludge, and transport them to an approved disposal location.
A system of perforated pipes or drain tiles is installed in trenches or on a gravel bed one to three feet below the surface of the ground.
As water trickles out of the pipes, the soil and its microorganisms function as natural filters, removing impurities from the water as it passes through them.
However, it isn’t a possibility for every single lot.
It will only work if there is adequate of well-draining soil above the water table to support it.
You’ll need an alternative system if your soil type, property size, or proximity to a wetland prevents you from using a conventional system. An alternative system is one that includes an improved septic tank, drainfield, or both. These systems are more expensive to install than simple systems, however the cost varies greatly based on your location, your local environmental standards, and the technology you require to be installed. Here are a few examples of the most prevalent kinds. Treatment alternatives are number one.
- It is possible to get away with a smaller drainfield—one that is built on a site that does not drain well—or with a site that is adjacent to a lake or stream, in which case you must adhere to tougher environmental regulations.
- They break down materials considerably more quickly than the anaerobic bacteria found in traditional septic tanks, resulting in cleaner water being discharged into the drainage field.
- It is possible to use an aerobic unit to replace or supplement a septic tank, or to function in conjunction with one.
- Filtering water is accomplished by the use of a huge underground or above-ground box that is filled with sand.
- After that, the water trickles through the sand before draining into the drainfield below.
- It also serves as an alternative to drainfields by enabling fluids to drain into the earth under the surface.
- Alternatives to Drainfields Alternate treatment systems fall into two categories: those that treat the drainfield end of the process and those that treat the process itself.
- These systems aid in the safe dispersion of water in areas where soil conditions are poor or when there is insufficient open space for a normal drainfield.
- It is utilized in situations where the soil is thin or contains excessive clay, or where the water table is very high.
- Water trickles out over a vast area in controlled dosages from a pump chamber in drip irrigation, which costs between $2,500 and $15,000, depending on the size of the drainfield.
Because the plumbing is just 6 to 8 inches belowground, you may need to filter the water first, maybe with an aerobic unit, due to the shallow depth of the pipes. In addition, you’ll need a filter and frequent maintenance to keep the system from becoming clogged.

The possibility of future difficulties is reduced if the original soil, bedding materials, depth to groundwater, backfill materials, and prospective stress loads are properly evaluated in the first place. When installing a tank, make sure to follow any manufacturer-specific installation instructions that may be included.
- Verify that the tank(s) are at the proper height and orientation in relation to the design.
- When connecting the stub-out to the tank, the collecting pipe should have a slope of between 1 and 2 percent (or 1/8 to 1/4 inch drop per foot of run) to ensure proper drainage.
- Note that in systems that rely solely on gravity flow, the height of the soil treatment area serves as the regulating elevation, which is particularly essential.
- If there are any preceding components that send effluent to a dosing tank by gravity flow, the height of the dosing tank intake is determined by the elevation of those components; it must be set deep enough.
- Tanks should be kept as shallow as feasible in order to reduce soil pressure, limit potential groundwater intrusion, and make maintenance operations more efficient.

Alerts about Septic Tanks+ A quantifiable, predictable and avoidable factor in tank movement after installation is tank movement during installation. The possibility of future difficulties is reduced if the original soil, bedding materials, depth to groundwater, backfill materials, and possible stress loads are properly evaluated. Any manufacturer-specific installation instructions should be followed when installing a tank. The tank’s placement should be staked out in order to adequately prepare the ground for the excavation. Verify that the tank(s) is(are) at the proper height and orientation with respect to the plan. It is the installer’s responsibility to address elevation standards that must be satisfied for gravity flow with the responsible party if the plumber’s stub-out is not his or her responsibility. Between one and two percent (i.e., an eighth- and a quarter-inch drop per foot of run) should be the slope of the collecting pipe from the stub-out to the tank. Because the height of succeeding components that receive effluent by gravity flow is regulated by the elevation of a septic tank outflow, the outlet must be positioned high enough to allow for this to happen. Note that in systems that rely solely on gravity flow, the height of the soil treatment area serves as the regulating elevation, which is particularly significant. It is important to determine all other elevations in relation to the elevation of the soil treatment area in order to avoid installing the system too deeply. If there are any preceding components that send effluent to a dosing tank by gravity flow, the height of the dosing tank intake is determined by the elevation of those components
- It must be set sufficiently deep. It is crucial to evaluate the complete treatment train since every tank may have many inlets with varying regulating altitudes. Tanks should be kept as shallow as feasible in order to reduce soil pressure, limit potential groundwater intrusion, and make management tasks easier. It is possible that water will be present in the excavation in locations where groundwater levels are high. This indicates the necessity to dewater the excavation. These precautions may only be necessary during the installation process, but they may also be required as a permanent element of the system on rare occasions. It should be noted that the requirement for dewatering indicates that the safety risk on the site has greatly increased. OSHA norms and regulations must be followed, as well as all necessary measures and safeguards. When it comes to dewatering, there are a range of options available.
Before installing a level tank, the excavation must be level (with bedding material, if necessary) and clear of any big rocks or debris, which must be removed prior to installing the tank. It is critical that the base of all tanks be stabilized with adequate bedding before the tank may be used. Natural dirt can sometimes be used as a good bedding material in certain circumstances. This is something that the installer should confirm with the local authorities. To ensure that the bottom of the hole remains relatively undisturbed, it is critical to avoid overexcavating native soil while using it as bedding in order to retain relatively undisturbed conditions at the bottom of the hole.
- It may be essential to add clean granular material to reestablish the proper height when this occurs.
- It does not matter what type of material was used to build the tank; the bedding material for all tanks should be devoid of clods, big pebbles, frozen materials, and garbage, among other things.
- Material requirements for bedding nonconcrete tanks should be obtained from the manufacturer in advance of usage.
- It is possible to regulate the migration of penalties in two ways: either by purposefully allowing vacant areas to fill during the installation process or by using steps to prevent fines from migrating after the installation is complete.
- Alternatively, washed rock that has been graded so that any vacuum areas are filled with smaller particles can be utilized to fill in the gaps.
- Indicate the type of bedding material used as well as the depth of bedding.
- Some scenarios may need the installation of a concrete pad in order to successfully hold the grade and establish a solid foundation.
A concrete tank with a clean bottom can form a bond with wet concrete, reducing the amount of buoyancy it has in the water.
It is possible that putting a tank with a nonlevel bottom on a dry concrete surface will result in pressure points that will cause the tank’s bottom to shatter.
Guarantee that the tank’s structural integrity is not compromised once it has been installed in the excavation to ensure that no damage or movement has taken place.
This is necessary in order to ensure that the inlet and outflow are at the proper relative elevations with respect to one another.
It is vital to adhere to OSHA safety regulations.

Septic System Permitting
Before installing a level tank, the excavation must be level (with bedding material, if necessary) and clear of any big rocks or debris, which must be removed prior to installation. Every tank’s base must be properly stabilized with adequate bedding, and this is of critical importance. Occasionally, naturally existing dirt can be used as a bedding material in certain circumstances. Local restrictions on this should be checked by the installation. To ensure that the bottom of the hole remains reasonably undisturbed, it is critical to avoid overexcavating native soil while using it as bedding in order to prevent the soil from becoming too compacted.
- It may be essential to add clean granular material to reestablish the proper height when this happens.
- It does not matter what type of material was used to create the tank; the bedding material for all tanks should be devoid of clods, big pebbles, frozen materials, and garbage, among other things.
- Material requirements for bedding nonconcrete tanks should be obtained from the manufacturer or from the supplier.
- It is possible to regulate the migration of penalties in two ways: either by purposefully allowing vacant areas to fill during the installation process or by employing steps to prevent fines from migrating after the installation is complete.
- Alternately, graded washed rock that has been filled with finer particles to fill in the voids might be utilized instead.
- The bedding material and depth should be specified in this section.
- In rare cases, the use of a concrete pad may be required in order to successfully maintain the grade and establish a solid foundation.
Having a clean bottom on a concrete tank might help it to bond with the wet concrete and reduce its buoyancy to a certain extent Despite the fact that the bottom of concrete tanks is often level, it is not guaranteed to be completely level.
Always double-check to ensure that the tank has been properly positioned in the excavation with respect to the inlet and outflow pipes.
Examine whether or not the tank is horizontal in the excavation using a laser or a level.
It is important to remember that personnel must be in a safe posture when tanks are being filled.

What size of septic tank do I need?
Probably one of the last things on your mind when you are constructing a new house is the location of your septic system. After all, shopping for tanks isn’t nearly as entertaining as shopping for cabinetry, appliances, and floor coverings. Although you would never brag about it, your guests will be aware if you do not have the proper septic tank placed in your home or business.
septic tanks for new home construction
The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size. Of course, all of this is dependent on the number of people who live in the house as well as the amount of water and waste that will be disposed of through the plumbing system.
For the most accurate assessment of your septic tank needs, you should speak with an experienced and trustworthy sewer business representative. They can assist you in planning the intricacies of your septic system, including which sort of septic system will be most beneficial to you.
planning your drainfield
Here are some helpful hints for deciding where to locate your drainfield when you’re designing it.
- Vehicles should not be allowed on or around the drainfield. Planting trees or anything else with deep roots along the bed of the drain field is not recommended. The roots jam the pipes on a regular basis. Downspouts and sump pumps should not be discharged into the septic system. Do not tamper with or change natural drainage features without first researching and evaluating the consequences of your actions on the drainage field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other materials. Create easy access to your septic tank cover by placing it near the entrance. Easy maintenance and inspection are made possible as a result. To aid with evaporation and erosion prevention, plant grass in the area.
a home addition may mean a new septic tank
Do not make any big additions or renovations to your house or company until you have had the size of your septic system assessed. If you want to build a house addition that is more than 10% of your total floor space, increases the number of rooms, or necessitates the installation of new plumbing, you will almost certainly need to expand your septic tank.

common septic questions
Here are some of the most frequently asked questions by our septic customers.
How do I determine the size of my septic tank?
If you have a rectangular tank, multiply the inner height by the length to get the overall height of the tank. In order to find out how many gallons your septic tank contains, divide the number by.1337.1337
How many bedrooms does a 500-gallon septic tank support?
The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size.
How deep in the ground is a septic tank?
Your septic system is normally buried between four inches and four feet underground, depending on the climate.
Aeration Septic – The Top Five Items to Keep Out of Your Septic System
Despite the fact that there are several alternative ways to dispose of trash within the home, some people just opt to use their toilet or garbage disposal for materials that do not belong in these pieces of equipment – which may put their septic system at risk. There are certain things that a toilet is supposed to handle and rid of, such as body waste, particular paper products, and the occasional spider that gets tangled in toilet paper, but there are other items that people flush that can cause far more harm than good.
You might believe that “if it flushes, it’s alright,” but this isn’t always the case, even when it comes to goods that are advertised as safe to flush as a form of disposal.
What is a septic system?
As previously stated, a septic system installed within a home serves as a waste disposal system, processing and eliminating wastewater generated within the residence. For those who have an anaerobic or aerobic septic system in their house, this implies that they are not reliant on the city or town’s sewage system to transport and treat their waste water. As with all other systems and components of the home, a septic tank system is composed of several moving parts and features, all of which must be properly maintained in order to perform at peak performance.
The most reliable approach to determine whether or not your septic system is completely operational is to hire the services of a septic tank inspector, who can (and will) supply you with a thorough septic tank inspection report following each visit to your property.
The more you understand about your system and how it should operate, the less likely it is that you will suffer difficulties such as braking, clogging, or backups into your house.
While there are a variety of items that might create problems when they are flushed down the toilet or placed through the trash disposal, some of the most prevalent are items that people do not think twice about flushing or putting through the garbage disposal.
Here’s a list of the top five things you should avoid introducing into your home’s septic system:
- Coffee grounds: While coffee grounds are not flushed, they frequently make their way into a garbage disposal and, ultimately, into the septic tank. Because of their texture, bacteria have a tough time breaking them down, which can put your septic system in risk over time as they accumulate. One excellent comparison is to think of these grounds as if they were gravel, despite the fact that they are far smaller. In the long run, the number of coffee grounds that do not decompose will contribute to an increase in the amount of solids (or sludge) present in the system, which might cause it to malfunction. Strong disinfectants, such as bleach: Because a properly functioning septic system relies on beneficial bacteria to break down waste, introducing these sorts of chemicals into the system in excessive quantities can be detrimental to the system. The weekly cleanings and the introduction of these chemicals into the toilet bowl insert in tiny amounts per flush are both perfectly acceptable practices
- Nevertheless, the use of excessive amounts is not encouraged. A decrease in the quantity of bacteria present in the holding and treatment tanks, which is a “living system,” might lead to an increase in the amount of solid waste accumulating in the system, which may necessitate more regular visits from a septic services specialist. Contrary to popular belief, condoms, disposable diapers, flushable wipes, and tampons are not as safe to flush as you may assume. Due to the fact that rubber does not degrade within the system, flushing condoms may put a septic system at risk of failure. Although the materials that are used to manufacture disposable diapers and tampons are termed biodegradable, this does not imply that they are beneficial to the general health of the system. However, while they will ultimately fail within the system, it may take a long time for them to do so, resulting in these objects remaining in the system for extended periods of time and causing further problems. Is it one of these other problems? These huge things have the potential to block pipes or become caught around the motor of a septic system, leading it to fail. A septic motor is a high-priced device that will normally cost upwards of $600 to repair or replace. Is taking this chance worth it? Grease and oil derived from the cooking process: Despite the fact that it may appear simple to simply drop these items down the drain while cleaning pots and pans, they may cause more harm than good. Although some oil and grease can unavoidably enter a septic system, an excessive amount of this will undoubtedly cause difficulties over time, especially in older homes with older septic systems. What is the explanation behind this? Over time, these materials have a tendency to harden and solidify, making it more difficult to break them down. The particles may also become attached to the sides of the pipes and walls of the septic tank, as well as to the moving mechanisms within it, causing backups, blockages, and overflow – or even a breakdown of the aerator or any other affected sections. Medications: Additionally, drugs have the potential to kill the bacteria that must be present in a septic system when they are flushed, and in some cases, they do so. This does not just apply to unused tablets
- Liquid drugs should never be flushed down the toilet too. Many of these prescriptions contain high amounts of antibiotics, and when these pills are flushed down the toilet, the chemicals in these medications will disrupt the delicate balance that must exist in the tank. Another item to take into consideration? If there is a problem with your septic tank – such as an undiscovered leak – these chemicals will be released into the environment as well, and this is harmful.
There are options for disposing of all of these products that are not limited to the sink or toilet, and homeowners should consider taking advantage of these options. Even if it means that trash bags will fill up quickly or that an empty jar will be required to collect grease, making these decisions will save you time, worry, and most likely a significant amount of money in the long run. Septic system maintenance is neither difficult nor prohibitively expensive as long as you follow the recommendations of septic service professionals.
For those who have not complied with recommendations and may have introduced items such as these into their system?
Don’t be afraid to ask about the various septic system treatment options available to those who need to reintroduce good bacteria into their systems while also eliminating some of the known issues.
Avoid Putting These Items Into Your Septic System
Residents of residential properties with septic systems must exercise caution while flushing toilet paper or other toilet paper down the toilet. Eventually, anything you flush down the toilet or down the drain will wind up in the septic tank, and not everything will be suited for the tank. Here are some objects that should never be dumped into your septic system, as well as instructions on how to properly dispose of them. Products for Feminine Hygiene Place the trash in the garbage can. A septic tank is safe to flush down with toilet paper that has been intended to decompose fast in a septic tank; nevertheless, this is about the only paper product that should be flushed down a toilet that is connected to a septic system.
- Tampons and some wet wipes are appropriate for municipal water systems and will flow through pipes, but they will cause difficulties in a septic tank because they contain chemicals that are toxic to bacteria.
- Using more of these goods, the available capacity in your tank will decline until you are forced to have your tank pumped out completely.
- The number of times you’ll need a service depends on how many individuals are flushing these things, but even if only one person is flushing these items, your tank’s service period will be reduced.
- If people are uncomfortable with the idea of seeing items in the garbage when they use the restroom, you may purchase a tiny covered trash bin for the room that keeps its contents hidden from view.
- Coffee grounds are a type of soil that is rich in nutrients.
- For two reasons, coffee grinds should never be allowed to enter your septic tank.
- When this occurs, the entire system stops to function as it is intended to do.
The bacteria survive best in a pH range between 6.5 and 7.5, with a preference for pH values between 6.5 and 7.
This is more acidic than the microorganisms in a tank are capable of withstanding.
Although the liquid in the tank will not be transformed into anything like a cup of coffee, the chemicals that drain from the grounds will acidify the tank in the same way that tap water does when coffee is brewed in a coffee pot.
If you flush coffee grounds down the toilet on a daily basis, they will build and make the tank too acidic for the bacteria to survive.
Useless coffee grounds are best disposed of in a compost pile, which you can simply create if you don’t already have one.
To compost coffee grounds if you don’t already do so, simply toss them in a heap and they’ll begin to decompose on their own as nature takes its course.
Ticks, which may transmit a variety of deadly diseases, should not be flushed down the toilet or into a septic tank – but not because it is harmful to the tank.
Ticks do not drown while submerged in water, therefore flushing them down your home’s plumbing and into your septic tank will not result in their death.
If the creature resurfaces after a period of time, it will still be alive and will be able to reproduce, make its way to your yard, and attack animals or people once more.
Ticks are poisonous to alcohol and will die if they come into contact with it, therefore most people have a bottle of rubbing alcohol in their home.
Even with the finest maintenance, a septic system will require service from time to time. Contact Walters Environmental Services if you need to have your septic tank pumped out.
Procedures and Criteria for Installing a New Septic System – Malheur County Oregon
What is the purpose of requiring permits? The permitting procedure guarantees that septic systems are installed and maintained in a manner that protects both human health and the surrounding environment. On-site programs are administered by the DEQ in some counties; in other counties, the County government acts as an agent on behalf of the Department of Environmental Quality (DEQ). The Onsite Program is overseen by the Environmental Health Department of Malheur County, which is part of the Oregon Department of Public Health.
- A Construction-Installation Permit is often required to establish a septic system for a single-family residence or for a system with an anticipated sewage flow of less than 2,500 gallons per day, depending on the circumstances.
- If the building and installation process takes longer than expected, it may be possible to renew or restart the contract for an extra price.
- There are two phases to this process.
- It is necessary to do a Site Evaluation in order to identify which kind and size of system is most appropriate for your property.
- The second step is obtaining a permission.
- What are the fees associated with obtaining a permit?
Step 1:The Site Evaluation
Criteria for Site Evaluation In many cases, the appropriateness of a proposed septic system site is decided by the kind and depth of the soil as well as the depth to the water table. Some other elements to consider include the size of the land, its slope, the position of the system in relation to streams, wells, cuts and fills, and whether or not sewage service is accessible on the property. In addition, there must be adequate space available for a complete system replacement in the event that the system fails.
- Process for Evaluating a Site 1.
- There must be a tax lot map, a comprehensive sketch of the planned development, and driving instructions to the land included in the submission.
- The Site Evaluation information package contains detailed information on the specific criteria for test pits.
- Following receipt of your completed application, an Onsite Specialist will visit your property to conduct a Site Evaluation of the property.
- In most cases, we will respond to completed Site Evaluation applications within three (3) weeks of receiving them; however, during the summer months, this may take up to five (5) weeks.
- You will obtain a Site Evaluation Report that defines the allowed area, the kind and size of the septic system that is necessary, as well as any specific criteria that may be applicable.
In addition, the Site Evaluation Report will provide you with information on how to apply for a site evaluation report review as well as how to ask for a variance from any regulation or standard, among other things.
Step 2:The Permit
Criteria for obtaining a permit Before you may submit an application for a Construction-Installation permit, you must first get a satisfactory Site Evaluation Report. Application for a permit can be received at the Environmental Health Office, or applications can be downloaded from the website listed below. Process for obtaining a permit1. To avoid a delay, ensure that the application is completely completed, including the signature of the owner or legally authorized agent, and that it is sent with the appropriate fees.
Detail designs and specifications for the system’s installation are included in this section.
The Department of Buildings will issue a Construction-Installation Permit within 20 days of receiving a fully submitted application.
Any modifications must be approved by the county’s onsite agent before they may be implemented.
All equipment must be installed and operated in accordance with the manufacturer’s guidelines.
Some complicated systems, such as sand filter systems, necessitate inspections at several phases of development, and the permit specifies the inspection criteria for each stage.
This document must be signed by the installer, who is confirming that the system was installed in accordance with the DEQ guidelines.
You may proceed with the installation when a satisfactory inspection has been completed. You will get a Certificate of Satisfactory Completion (CSC) in the mail upon completion of the course. You may begin utilizing the septic system immediately after receiving the CSC.
