How often pump septic tank?

Inspect and Pump Frequently The average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years.

Who designs septic systems?

Specialist #2: Septic System Designer Second, a design is completed by either a registered sanitarian or professional engineer, which is based on the information gathered during the site evaluation. Some designers are also site evaluators.

Can you design your own septic system?

To save homeowners the cost of hiring a professional septic designer and excavator, you can build a septic tank system yourself. The installation of new septic systems is expensive even if you build your own DIY septic tank and drainage systems by hand.

How do you build a septic tank drain field?

There should be at least 100 feet of drain field for a 1,000-gallon septic tank. This can be accomplished by making four trenches 25 feet long or two trenches 50 feet long. The trenches should be at a slight downward slant of no more than 1/4 inch per 8 feet of pipe.

What is the size of septic tank for 25 users?

Septic tank size for 25 users:- For 25 users, minimum/ standard size of septic tank could be 3.6m × 1.4m × 1.3m (12ft × 4.5ft × 4.25ft) in respect to their Length, breadth and depth.

What is minimum capacity of septic tank?

Septic tank shall have minimum width of 750 mm, minimum depth of one metre below water level and a minimum liquid capacity of 1 000 litres.

What is standard size of septic tank?

Length of septic tank (L) should be taken as 9feet 9 inches or 9.75 feet. Breadth of septic tank (B) should be taken as 6 feet 3 inches or 6.25 feet. The standard height (D) of septic tank should be taken as 5 feet 9 inches or 5.75 feet.

How to Care for Your Septic System

The size and kind of tank required are the two most important considerations when establishing a new septic system. It is becoming increasingly popular in the United States to have onsite wastewater treatment for newly constructed residences; 33 percent of newly constructed homes have this option. It is the least expensive approach available for treating residential wastewater when paired with a soil absorption system or a drain field, which is why septic tank systems are so popular. Septic tank sizes are mostly determined by the size of the house and the number of people that will be residing in the residence.

Introduction to Septic Tanks Typically, a septic tank is a self-contained container that is used to store wastewater from a house or other building.

Solid waste settles to the bottom of the tank after entering it, forming a layer known as the sludge layer as a result of this settling.

This stratum is composed of wastewater, often known as effluent.

  • Septic tanks are available in a variety of configurations.
  • Septic tanks made of concrete; septic tanks made of polyethylene/plastic; and septic tanks made of fiberglass.
  • Polyethylene and fiberglass are one-piece items that are significantly lighter in weight than steel and aluminum.
  • Obtaining information from your local building department about onsite wastewater treatment laws and requirements prior to acquiring a septic tank system is highly recommended before making any purchases.
  • The square footage of the property, the number of bedrooms, and the number of people who will be residing there are all important considerations to consider.
  • Septic tanks for one and two bedroom residences that are less than 1,500 square feet and 1,000 gallon septic tanks for three bedroom homes that are less than 2,500 square feet are required.
  • Unless otherwise specified, the figures shown above are estimates.
  • A competent plumbing contractor licensed in your region should be consulted before purchasing a septic tank system to examine the many septic tank alternatives available.

  • Inspect and pump your drainfield on a regular basis
  • Conserve water
  • Dispose of waste properly
  • And keep your drainfield in good condition.

Inspect and Pump Frequently

Inspection of the ordinary residential septic system should be performed by a septic service specialist at least once every three years. Household septic tanks are normally pumped every three to five years, depending on how often they are used. Alternative systems that use electrical float switches, pumps, or mechanical components should be examined more frequently, typically once a year, to ensure that they are in proper working order. Because alternative systems contain mechanical components, it is essential to have a service contract.

  • The size of the household
  • The total amount of wastewater produced
  • The amount of solids present in wastewater
  • The size of the septic tank

Service provider coming? Here is what you need to know.

When you contact a septic service provider, he or she will inspect your septic tank for leaks as well as the scum and sludge layers that have built up over time. Maintain detailed records of any maintenance work conducted on your septic system. Because of the T-shaped outlet on the side of your tank, sludge and scum will not be able to escape from the tank and travel to the drainfield region. A pumping is required when the bottom of the scum layer or the top of the sludge layer is within six inches of the bottom of the outlet, or if the top of the sludge layer is within 12 inches of the bottom of the outlet.

In the service report for your system, the service provider should mention the completion of repairs as well as the condition of the tank.

An online septic finder from the National Onsite Wastewater Recycling Association (NOWRA) makes it simple to identify service specialists in your region.

Use Water Efficiently

In a normal single-family house, the average indoor water consumption is about 70 gallons per person, per day, on average. A single leaking or running toilet can waste as much as 200 gallons of water each day, depending on the situation. The septic system is responsible for disposing of all of the water that a residence sends down its pipes. The more water that is conserved in a household, the less water that enters the sewage system. A septic system that is operated efficiently will operate more efficiently and will have a lower chance of failure.

  • Toilets with a high level of efficiency. The usage of toilets accounts for 25 to 30% of total home water use. Many older homes have toilets with reservoirs that hold 3.5 to 5 gallons of water, but contemporary, high-efficiency toilets consume 1.6 gallons or less of water for each flush. Changing out your old toilets for high-efficiency versions is a simple approach to lessen the amount of household water that gets into your septic system. Aerators for faucets and high-efficiency showerheads are also available. Reduce water use and the volume of water entering your septic system by using faucet aerators, high-efficiency showerheads, and shower flow restriction devices. Machines for washing clothes. Water and energy are wasted when little loads of laundry are washed on the large-load cycle of your washing machine. By selecting the appropriate load size, you may limit the amount of water wasted. If you are unable to specify a load size, only complete loads of washing should be performed. Washing machine use should be spread throughout the week if at all possible. Doing all of your household laundry in one day may appear to be a time-saving strategy
  • Nevertheless, it can cause damage to your septic system by denying your septic tank adequate time to handle waste and may even cause your drainfield to overflow. Machines that have earned theENERGY STARlabel consume 35 percent less energy and 50 percent less water than ordinary ones, according to the Environmental Protection Agency. Other Energy Star appliances can save you a lot of money on your energy and water bills.

Properly Dispose of Waste

Everything that goes down your drains, whether it’s flushed down the toilet, ground up in the trash disposal, or poured down the sink, shower, or bath, ends up in your septic system, which is where it belongs. What you flush down the toilet has an impact on how effectively your septic system functions.

Toilets aren’t trash cans!

Your septic system is not a garbage disposal system. A simple rule of thumb is to never flush anything other than human waste and toilet paper down the toilet. Never flush a toilet:

  • Cooking grease or oil
  • Wipes that are not flushable, such as baby wipes or other wet wipes
  • Photographic solutions
  • Feminine hygiene items Condoms
  • Medical supplies such as dental floss and disposable diapers, cigarette butts and coffee grounds, cat litter and paper towels, pharmaceuticals, and household chemicals such as gasoline and oil, insecticides, antifreeze, and paint or paint thinners

Toilet Paper Needs to Be Flushed!

Check out this video, which demonstrates why the only item you should flush down your toilet are toilet paper rolls.

Think at the sink!

Toilet Paper Must Be Flushed! To understand why the only item you should flush down your toilet is toilet paper, watch this video.

  • If you have a clogged drain, avoid using chemical drain openers. To prevent this from happening, use hot water or a drain snake
  • Never dump cooking oil or grease down the sink or toilet. It is never a good idea to flush oil-based paints, solvents, or huge quantities of harmful cleansers down the toilet. Even latex paint waste should be kept to a bare minimum. Disposal of rubbish should be avoided or limited to a minimum. Fats, grease, and particles will be considerably reduced in your septic tank, reducing the likelihood of your drainfield being clogged.

Own a recreational vehicle (RV), boat or mobile home?

If you have ever spent any time in an RV or boat, you are undoubtedly familiar with the issue of aromas emanating from sewage holding tanks.

  • The National Small Flows Clearinghouse’s Septic System Care hotline, which may be reached toll-free at 800-624-8301, has a factsheet on safe wastewater disposal for RV, boat, and mobile home owners and operators.

Maintain Your Drainfield

It is critical that you maintain the integrity of your drainfield, which is a component of your septic system that filters impurities from the liquid that emerges from your septic tank once it has been installed. Here are some things you should do to keep it in good condition:

  • Parking: Do not park or drive on your drainfield at any time. Plan your tree plantings so that their roots do not grow into your drainfield or septic system. An experienced septic service provider can recommend the appropriate distance for your septic tank and surrounding landscaping, based on your specific situation. Locating Your Drainfield: Keep any roof drains, sump pumps, and other rainfall drainage systems away from the drainfield area. Excess water causes the wastewater treatment process to slow down or halt completely.

Septic Tank Installation and Pricing

To process and dispose of waste, a septic system has an underground septic tank constructed of plastic, concrete, fiberglass, or other material that is located beneath the earth. Designed to provide a customized wastewater treatment solution for business and residential locations, this system may be installed anywhere. Although it is possible to construct a septic tank on your own, we recommend that you hire a professional to do it owing to the amount of skill and specific equipment required.

Who Needs a Septic Tank?

For the most part, in densely populated areas of the nation, a home’s plumbing system is directly connected to the municipal sewer system. Because municipal sewer lines are not readily available in more rural regions, sewage must be treated in a septic tank. If you’re moving into a newly constructed house or onto land that doesn’t already have a septic tank, you’ll be responsible for putting in a septic system on your own.

How to Prepare for Your Septic Tank Installation

Here are a few pointers to keep in mind to make sure your septic tank installation goes as smoothly as possible.

Receive Multiple Estimates

Receiving quotations from licensed septic tank installers and reading reviews about each firm using trustworthy, third-party customer evaluations should be done before any excavation or signing of any paperwork is done. Examine your options for a contractor and make sure they have the appropriate insurance and license, as well as the ability to include critical preparations such as excavation and drain field testing in their quotation.

Test the Soil and Obtain a Permit

For septic systems to function properly, permeable soil surrounding the tank must absorb and naturally handle liquid waste, ensuring that it does not pollute runoff water or seep into the groundwater. The drain or leach field is the name given to this region. Before establishing a septic tank, you are required by law to do a percolation test, sometimes known as a “perc” test. This test indicates that the soil fits the specifications established by the city and the local health agency. In most cases, suitable levels of permeable materials, such as sand or gravel, are necessary in a soil’s composition.

Note: If you wish to install a septic tank on your property, you must first ensure that the ground passes the percolation test. Prior to acquiring the land that you want to utilize for residential purposes, we recommend that you obtain a soil test.

Plan for Excavation

Excavation of the vast quantity of land required for a septic tank necessitates the use of heavy machinery. If you are presently residing on the property, be careful to account for landscaping fees to repair any damage that may have occurred during the excavation process. Plan the excavation for your new home at a period when it will have the least influence on the construction process if you are constructing a new home. Typically, this occurs before to the paving of roads and walkways, but after the basic structure of the home has been constructed and erected.

The Cost of Installing a Septic Tank

There are a few installation charges and additional expenditures connected with constructing a new septic system, ranging from a percolation test to emptying the septic tank and everything in between.

Percolation Test

A percolation test can range in price from $250 to $1,000, depending on the area of the property and the soil characteristics that are being tested. Ordinarily, specialists will only excavate a small number of holes in the intended leach field region; however, if a land study is required to identify where to excavate, the cost of your test may rise.

Building Permit Application

A permit will be required if you want to install a septic tank on your property. State-by-state variations in permit prices exist, however they are normally priced around $200 and must be renewed every few years on average.

Excavation and Installation

It is necessary to get a permission in order to construct a septic tank on your site. State-by-state variations in permit prices exist, although they are normally priced around $200 and must be renewed every few years at the very least.

Types of Septic Tank Systems

Septic system that is used in the traditional sense Traditionally, a septic system relies on gravity to transport waste from the home into the septic tank. Solid trash settles at the bottom of the sewage treatment plant, while liquid sewage rises to the top. Whenever the amount of liquid sewage increases over the outflow pipe, the liquid waste is discharged into the drain field, where it continues to disintegrate. This type of traditional septic system is generally the most economical, with an average cost of roughly $3,000 on the market today.

Drain fields for alternative systems require less land than conventional systems and discharge cleaner effluent.

Septic system that has been engineered A poorly developed soil or a property placed on an uphill slope need the installation of an engineered septic system, which is the most difficult to install.

It is necessary to pump the liquid waste onto a leach field, rather than depending on gravity to drain it, in order to ensure that it is equally dispersed across the land. The average cost of these systems is roughly $8,000.

Types of Septic Tanks

  • Concrete septic tanks are long-lasting and rust-proof, but they are difficult to repair if they are damaged. It is possible that concrete tanks will cost up to $2,000 depending on their size. Plastic —While plastic tanks are cost-effective, they are also susceptible to damage. They are around $1,200 in price. Fiberglass —While fiberglass septic tanks are more durable than their plastic counterparts, they are susceptible to shifting or displacement if the water table rises to an excessive level. Depending on the model, these tanks may cost up to $2,000

Using Your Septic Tank

It is important to maintain the area around your new septic tank’s drain field and to frequently check your tank using the lids included with it. Never use a trash disposal in conjunction with your septic tank since it might cause the system to clog. Additionally, avoid driving over the land where your septic tank is located or putting heavy gear on top of your septic tank or drain field to prevent damage. Most of the time, after five years of septic system use, you’ll need to arrange a cleaning and pumping of the system.

5 Tips For Building and Installing a Septic Tank

It is necessary to establish a septic tank or sewage treatment plant for every dwelling or development that does not have access to public sewers. Septic tanks, also known as off-mains drainage solutions, are a very effective method of dealing with the sewage and wastewater generated by developments that do not have a main sewer connection to the city. Because your septic system is a crucial component of your infrastructure, it is important that you construct your septic system appropriately in order to assure trouble-free operation over the long term.

1 – Septic system design

It is always important to start with a basic design when embarking on a project of any kind. This means that when you get on the job site, you will have a clear understanding of what has to be done. A septic system is made up of two major components. The tank and the percolation area or discharge area are two separate areas. Septic systems are typically designed based on the number of people who will be living in the house. Please feel free to consult the code of practice for more detailed information on septic tank sizing.

  • For the vast majority of septic systems, this is the recommended method of waste disposal.
  • The design of a soakaway is influenced by the soil conditions present on the property.
  • Here is where you can find detailed instructions on how to design your soakaway based on a quick test of your soil on the job site.
  • The installation of a sewage treatment plant, on the other hand, is almost always required in this situation since a sewage treatment plant achieves a far better level of treatment than a septic tank does.

As soon as you have determined whether you need to install a sewage treatment plant or a septic tank, as well as whether or not you need to install a percolation area or a direct discharge, you can begin work on the project site.

2 – Choosing the right septic tank or sewage treatment plant

The selection of the most appropriate septic tank or sewage treatment plant is an important phase in the process. You will have already decided whether you will be installing a soakaway or percolation area or whether you will be using a direct discharge system at this point. If you have a soakaway or percolation area, it may be possible to install a septic tank as an alternative. Septic tanks are typically made of concrete or plastic, depending on their size. Concrete tanks are extremely durable, but they require access for a truck-mounted crane in order to be installed.

  1. Septic tanks erected nowadays are often made of reinforced plastic and are as sturdy as their concrete counterparts in terms of strength.
  2. If you are purchasing a certified septic tank, you must ensure that it complies with the SR66 and EN12566-1 standards before purchasing.
  3. Modern technologies have resulted in the development of some very low-cost sewage treatment plants that are currently available on the market.
  4. Please go to our other blog article for further information on septic tank expenses.

3 – Installation

It is critical to select the most appropriate septic tank or sewage treatment plant for the job. The decision on whether to build a soakaway or percolation area, or whether to have a direct discharge, should have been made by this point. Septic tanks may be an alternative if you have a soakaway or percolation area, although they are not always required. Septic tanks are often made of concrete or plastic, depending on the manufacturer. Concrete tanks are extremely durable, but they require access for a truck-mounted crane in order to be installed properly.

Septic tanks erected nowadays are often made of reinforced plastic and are as sturdy as their concrete counterparts in terms of durability.

The SR66 and EN12566-1 criteria must be met by the septic tank that you are purchasing if you want it to be considered certified.

Nowadays, thanks to technological advancements, there are a number of low-cost sewage treatment facilities on the market.

If you are establishing a sewage treatment facility, you must ensure that it is certified to the SR66 and EN12566-3 requirements before proceeding. Please see our other blog article for more information on septic tank expenses.

4 – Ventilation

When installing a septic tank or sewage treatment plant, it is common to overlook the importance of proper ventilation in the process. On-site smell problems might be caused by inadequate ventilation. If the percolation trenches are not vented at the ends, it is critical that there is either a vent on the wastewater treatment plant or that there is a soil vent stack at the house where they are located. Please see this link for more information on preventing septic tank odors and venting septic tanks.

5 – Maintenance and operation access

Considering future maintenance should be taken into mind while building your sewage treatment facility. Any lids on the tank should not be buried under a thick layer of soil. In the future, access will be required for septic tank emptying, as well as for inspection and tests to ensure that the system is operating effectively. Because septic tank emptying companies typically only have 30m-long hoses for emptying tanks, the tank should be within 30m of a driveway to ensure that it is not clogged.

You should not underestimate the importance of your home’s sewage system.

This will ensure that your system is properly maintained.

How to Build a DIY Septic Tank System

You may install a septic tank system yourself to save money on the costs of hiring a professional septic designer and digger, which can add up quickly. Even if you design your own DIY septic tank and drainage system from scratch, the cost of installing a new septic system is high. Although it is possible to save money by installing your own septic tank system, it is not recommended.

Costs of a DIY Septic System

You may install a septic tank system on your own to save money on the costs of hiring a professional septic designer and digger. A new septic system is expensive, even if you build your own DIY septic tank and drainage system from scratch with your own hands. Even yet, constructing a septic tank system yourself can save you money. Read on for more information.

Before You Start Digging

Before you begin the actual building work, it is generally a good idea to do a thorough assessment of the situation. Get yourself a scale map of your home and property before you get your shovel out and start digging about in the dirt. The backyard, below the garage, or any side of the house that is near to a roadway are the greatest places to install a household septic system. The position of the septic system must be determined before any digging can begin. This is a very important phase in the process.

When installing a tank, it is vital that it is done right the first time.

The Site Evaluation

In most jurisdictions, the old perc test has been replaced by a site evaluation as a means of demonstrating to your local health authority the treatment characteristics of your property’s infrastructure.

DIY Perc Testing

In the past, the perc test was performed by simply dumping a pail of water into a tiny hole in the ground and then timed how quickly the water soaked into the soil with a stop-watch. The site inspection is carried out at the bottom of a 6-foot-deep trench. Unlike the perc test, which only measures the absorption speed of a small section of the property, the site evaluation measures the absorption speed of a much larger region over the soil face.

Soil Classification

The Soil Conservation Classification System of the United States Department of Agriculture is the soil classification system that is utilized in practically all states in the United States today. As you continue to examine down into the earth, you will see that most soil testing pits include three or more different types of soil.

Drainfield Trench Size

This does not affect the size of the drainfield, which is independent of the number of bathrooms or fixtures on the property. Almost all health departments employ the following methods to determine the flow rate:

  • An individual’s residence’s total number of bedrooms The amount of persons that are present in the residence
  • Water use on a daily basis

The volume of sewage that must be discharged into the drainfield is determined by the flow rate. Once you have determined the kind of soil under your prospective drainfield, use the table shown here to calculate the drainfield area necessary for your house size, and you will have the drainfield size you require.

Size of The Septic Tank

The size of a septic tank construction is decided by the number of people living in the home or on the land for which it is being built. Consult the metric standards for the area in which the construction is to take place before proceeding. This is the most accurate method of determining the amount of septic tank you should use when constructing your own septic tank system. The size of your DIY septic system will also decide how frequently you will need to have your DIY septic system pumped by a professional septic pumping service, which will be determined by the size of your septic system.

Creating the Drawings

Before we can begin construction on our septic system, we must first develop the necessary designs to fulfill the requirements of your local health authority. Your DIY septic system designs may need to be more detailed than you think they need be, depending on your state’s requirements. All structures, pathways, property borders, retaining walls, and the position of the original test holes, on the other hand, must be clearly depicted.

Drainfield Layout

Your drainfield plan will necessitate the construction of a minimum of two ditches of similar size. The division of the water flow into two, three, or more lines is accomplished by using a distribution box, also known as a D-box, to divide the flow. It is used in the distribution box to distribute water through pipes that include flow control valves in the form of eccentric plugs that distribute the water evenly across several drain lines.

The effluent must flow downhill from the tank outlet, through the distribution box, and down the individual trenches before being disposed of. These ditches should be dead leveled in order for the water to run out onto the ground beneath each trench.

Apply for a Building Permit

Now that you have the drawing, you should submit your ideas to the local health department’s office for consideration. You will be required to complete an application form as well as pay the applicable permission cost. Following that, you will need to wait for the designs to be examined and authorized by the board of directors before moving on to the final construction phase of the project.

Building a Septic Tank System

To begin the construction process, the first step is to sketch up a rough schematic of the septic system. You’ll utilize this layout to put your construction designs into action on the ground. It is necessary to project the layout and position of all of the different components of the septic design onto the site.

Excavation of the Septic Tank System

When it comes to digging the site in order to prepare for the construction of the septic tank and drain lines, it is important to pay close attention to elevation in order to get the best possible results. The health inspector will need to inspect the job one more time after you have finished all of the excavation before you can begin backfilling. Once you have finished all of the excavating, you will need to schedule another appointment with him for a final inspection of the job before you can begin backfilling.

Backfilling the Septic Tank System

During the building process, all of the tanks, pipelines, and vaults should be backfilled around the perimeter. Your local authority may mandate that all tanks be subjected to vacuum testing, pressure testing, or water testing. Aside from that, an increasing number of counties are demanding leak testing of the tank these days. Consequently, the final backfilling of the concrete tanks can be delayed until after the final inspection to check for leaks has been completed. The final backfilling should not be completed until after the final health department inspection has been completed.

Septic System Basics

When a household isn’t connected to a public sewage system, it normally relies on septic systems to treat and dispose of wastewater. Sewage treatment systems require a substantial financial commitment. The correct maintenance and upkeep of a well-designed, installed, and maintained system will provide years of dependable and low-cost service. The failure of a system can become a source of pollution and public health concern, resulting in property damage, ground and surfacewater pollution (such as contamination of well water used by you and your neighbors), and the spread of disease.

Aside from that, if you are planning to sell your property, your septic system has to be in good functioning order.

Septic systems are available in a variety of configurations to accommodate a wide range of soil and site conditions.

A conventional septic tank system is composed of three major components:

  • This is known as the Septic Tank. In order to remove particles from wastewater, store and partially decompose as much solid material as possible, while allowing the liquid (or effluent) to flow to the drainfield, a septic tank must be installed. more
  • The Drainage System After the particles have settled in the septic tank, the liquid wastewater (also known as effluent) is released to the drainfield, which is also known as an absorption or leach field, or both. more
  • The Soil is a very important factor. The soil under the drainfield is responsible for the ultimate treatment and disposal of the septic tank effluent once it has been treated. Following the passage of wastewater into the soil, organisms in the soil remediate the effluent before it percolates downward and outward, eventually entering ground or surface water sources. A drainfield’s efficacy is also affected by the kind of soil
  • For example, clay soils may be too tight to allow much wastewater to run through, while gravelly soil may be too coarse to give much treatment.
  • Septic System Inspection Done at Home In order to aid you in examining your system, a VideoField Guide and Checklist may be available at the bottom of the homepage.

Homeowners and residents have a significant impact on the functioning of their septic systems. Overloading the system with more water than it is capable of handling might result in system failure. A septic system can also be damaged by the improper disposal of chemicals or excess organic waste, such as that produced by a trash disposal. The following maintenance suggestions might assist you in ensuring that your system provides long-term, effective treatment of domestic waste.

Inspect and Pump Frequently

The most critical step in keeping your septic tank in good working order is to eliminate sludge and scum build-up before it may flow into the drainfield. The frequency with which your tank has to be pumped is determined by the size of the tank, the number of people in your family, the quantity of water utilized, and the amount of solids (from humans, garbage disposal, and any other waste) that enter the tank’s drainage system. Tanks should be pumped out on average every 3 to 5 years, depending on usage.

  • In order to keep your septic tank in good condition, you must remove sludge and scum buildup before it may wash into your drainfield. Depending on the size of your tank, the number of people in your family, how much water is utilized and how much solid waste (from humans, garbage disposals or any other sources) is entering the system, you may need to have your tank pumped on a regular basis. Pumping tanks every 3 to 5 years is a good rule of thumb. Please visit the following links for further information.

Use Water Efficiently

System failure is frequently caused by an excessive amount of water. The soil beneath the septic system must be able to absorb all of the water that is used in the residence. Too much water from the washing machine, dishwasher, toilets, bathtubs, and showers may not provide enough time for sludge and scum to separate properly in the drain. The less water that is consumed, the less water that enters the septic system, reducing the likelihood of system failure. For further information on water conservation, visit:

Minimize Solid Waste Disposal

What you flush down the toilet can have a significant influence on the performance of your septic system.

Many things do not breakdown properly, and as a result, they accumulate in your septic tank. If you have the option of disposing of it in another manner, do so rather than introducing it into your system.

Keep Chemicals Out of Your System

A significant influence on your septic system may be had by what you flush down the drain. Because many things do not breakdown properly, they accumulate in your septic tank and cause it to overflow. If you have the option of disposing of it in another manner, do so rather than introducing it into your body.

Septic System Additives

It is not essential to add a stimulant or an enhancer to a septic tank in order to assist it in functioning or “to restore bacterial equilibrium.” The naturally occurring bacteria required for the proper operation of the septic system are already present in human excrement. Septic systems, like automobiles, are designed to offer long-term, effective treatment of residential waste if they are properly run and maintained on a regular basis. The majority of systems that fail prematurely, on the other hand, are the result of poor maintenance.

  • In order to aid in the function of a septic tank or “restore bacterial equilibrium,” it is not essential to add a stimulant or an enhancer to it. The naturally existing bacteria required for the proper operation of the septic system may be found in human feces already. When properly run and maintained, septic systems, like automobiles, are meant to offer long-term, efficient treatment of residential waste. While some systems collapse early, the vast majority of them are caused by poor maintenance. Please call a competent septic specialist if you see any of the following indicators or believe that your septic system is experiencing issues.

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.

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

Vehicles should not be allowed on or near the drainfield. Planting trees or anything else with deep roots near the drain field’s bed is not recommended. Clogged pipes are frequently caused by the roots of plants; Downspouts and sump pumps should not be drained into the septic system; and If you want to tamper with or change natural drainage characteristics, do so after researching and evaluating the impact on the drain field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other similar materials.

Easy maintenance and inspection are made possible as a result of this; To aid with evaporation and erosion prevention, plant grass in the soil.

  • For a home addition that will result in increased use of your septic system, your local health department will require a letter from you that has been signed and authorized by a representative of your local health department confirming that your new septic system is capable of accommodating the increase in wastewater. It is not recommended that you replace your septic system without the assistance of a certified and competent contractor.

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.

Septic Systems

  • Approval for construction
  • Approval for operation
  • Approval for septic system
Many changes to systems require Approval for Construction

Preliminary approval for construction must be obtained prior to converting a structure from seasonal to full-time occupancy, prior to increasing the load on an existing septic system, and/or prior to commencing any additions to a structure. Preliminary approval must also be obtained prior to replacing or expanding a structure, subject to the requirements of RSA 485-A:38, II-a.

An inspector will determine whether the system meets requirements

A New Hampshire Department of Environmental Services inspector will inspect and assess the newly constructed septic system to confirm that it has been installed in line with the objective of the authorized design. An electronic Approval for Septic System Operation will be completed once the inspector has decided that the system complies with all relevant regulations. A digital copy of the approval will be kept on file with the New Hampshire Department of Environmental Services. Inspectors from different regions

Guidance and permit applications for septic systems

In the case of any structure from which wastewater will be discharged on site and to which a water supply is or will be connected, a septic system will be required to be installed. If your septic system is properly planned, implemented, and maintained, it should provide you with many years of trouble-free service. The New Hampshire Department of Environmental Services (NHDES) provides instructions for filing applications, which can also be completed online through e-permitting. Locate the relevant applications.

Archive Records

Considering that the Subsurface Systems Act was enacted only in 1967, there are no records in existence if the building was built before 1967. The majority of the septic systems constructed within 1,000 feet of a surface water during the period 1967 to 1971 are included in the state records. The catalog of these records may not necessarily contain all of the information. From 1967 until 1986, the state’s records were exclusively comprised of paper documents.

The municipality in which the structure is located may keep paper or electronic records of the structure’s history. From 1986 until the present, state records have been kept on paper with some computerized records thrown in. Make a request for an archive by filling out the form below.

Suggested Septic Design Drawing Requirements

Design Requirement Recommendations for the PDF Version Document Each and every item referred to in this document must be in compliance with 410 IAC 6-8.3. The requirements of 410 IAC 6-8.3 for septic system design do not list the components that must be included, but they do state that “plans of sufficient clarity so that it can be verified that the design of the residential on-site sewage system complies with the provisions of this rule” must be included. In order to achieve this goal, a very comprehensive septic design must be implemented.

  1. An excellent design will incorporate the most appropriate layout, system functioning, and cost considerations.
  2. Erroneous designs can result in improper installations, code breaches, and the need for costly remediation.
  3. This presents a significant problem for the health department.
  4. When it comes to septic design, accurate horizontal measurements are critical, but exact vertical measures (elevations) are essential.
  5. Making system grade elevations from third-party contour lines (for example, GIS or USGS maps, or topographic surveys performed by someone else) results in incorrect data and should not be permitted.
  6. Who has the ability to develop a system?
  7. These individuals may include, but are not limited to, septic installers, excavators, septic designers, builders, and engineers, among other professions.

It is recommended that the health department, as well as a designer with a laser level, be present when the borings are carried out.

2.The health department establishes the regulations for septic systems.

4.The design has been submitted to the health department for consideration.

6.Once approved, the plans are stamped with the words APPROVED and the date of approval by the health department.

The version (date) of plans that have been authorized must be specified on the permit card.

The number of bedrooms and the number of similar bedrooms (including residential outbuildings with plumbing) c.

Depths of trenches, both maximum and minimum (where applicable) e.Tillage depths for mound systems that have been proposed (if applicable) Prerequisites for a perimeter drain or an interceptor (if applicable) b.

The date of conception, as well as the date of revision and a description 2.The design drawing must be drawn to scale (1′′=20′ or 1′′=30′ is preferable).

If the design is still readable at a reduced size, it may be appropriate to utilize it.

3.Name and location of all components of the planned septic system, as well as their characteristics (brand and size of tanks (including effluent filter), pipe size and specifications, locations and lengths, pump type, and so on) 3.

6.Any water wells on the site and all wells within 75 feet of the planned system are to be considered.

When soil loading rates reach.75, well separation distances are doubled, unless the danger can be mitigated on-site via proper planning and engineering.

9.An already-existing tank (s).


A north arrow and a scale are included.

Future expansions, swimming pools, and outbuildings are being considered (if known) Cross section of trench, bed, or mound revealing depths and elevations of materials as well as the materials themselves.

14.The slope’s inclination (noted with arrow) 15.The location of public utilities (if known and when applicable) 16.Determination of the location of the reserve area (when applicable) The position and height of the temporary Bench Marks (which are normally set to 100.00′ unless local restrictions specify that USGS elevations must be used) 18.


When it is expected that a 100-year floodplain elevation would encroach on the site of a planned system, the health department must require floodplain elevations to be included in the design.

A lasting method must be used to designate the beginning and end of each trench, as well as the sand mound corners and gravel bed of the planned absorption field.


A sufficient number of grade and invert elevations to demonstrate drain depth, an appropriate slope, and the ability for water to flow freely by gravity to an adequate exit.

22.When it is believed that a 100-year floodplain elevation would encroach on the site of a planned system, the health department shall require floodplain elevations to be included in the design.

C.Details on the Dosing Tank: 1.The manufacturer, the size, and the kind of tank (shallow or standard) gallons per square inch 2.Specify the force main, the timetable, and the interior tank diameter.

The distance from the floor to the pump off in inches (pump must stay submerged for cooling) b.

Measure the distance between the “on” and “off” pumps in inches (multiplied by gallons per inch showsamount ofdose) d.

Display the distance and volume between the alarm being activated and the tank intake.

Inlet and outflow tank elevations are measured.

Route and height of the planned effluent force main leaving the tank are shown in Figure 8.

This elevation is required in order to demonstrate that the effluent force main will drain (back to the tank or forward to the field OR is proposed at frost layer).

15.Junction box location and configuration Protection measures must be put in place to prevent siphoning of liquid into or out of the dosing tank (when using a typical dosing tank with an electrical pump).

There must be a pump “in stock” or easily available from a local source in order for the design to be feasible.
