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.

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.

  • 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.

How Big of a Septic Tank Do I Need?

The size and kind of tank required for a new septic system are the two most important considerations to make before beginning the installation process. Private sewage disposal is becoming increasingly popular in the United States, with 33 percent of newly constructed residences choosing for on-site wastewater treatment as part of their construction. Septic tank systems, in conjunction with a soil absorption system, or a drain field, are the least costly way of treating residential wastewater currently available on the market.

  • The typical size of a home septic tank is from 750 gallons to 1,250 gallons in capacity.
  • The system is made up of two major components: the tank and the drain, often known as the soil absorption field or drain field.
  • Oil, grease, and soap residue combine to form the scum layer on the surface of the water.
  • With each filling of the tank, the effluent drains out of the tank and into the drain field, where it is absorbed by the earth.
  • Septic tanks are commonly utilized in residential construction and can be classified into three categories.
  • Polyethylene and fiberglass are one-piece products that are significantly lighter than steel.
  • In order to determine whether or not you need a septic tank system, check with your local building department to see what laws and requirements apply to onsite wastewater treatment.
  • The square footage of the property, the number of bedrooms, and the number of people who will be living there are all important considerations.
  • Septic tanks for one and two bedroom homes 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 recommended.
  • The figures listed above are only estimates.
  • Before acquiring a septic tank system, speak with a professional plumbing contractor who is licensed in your region about the many septic tank alternatives that are available to you.

Tank Types Express Septic Service

Septic tanks should be cleaned every 3 to 5 years, depending on the size of the household and how much water is used. When the septic tank is pump out on a regular basis, it will help to reduce the buildup of scum and sludge layers in the tank. Ideally, the scum layer should not be more than 24 inches thick. If the material is deeper than 24 inches, it will flow down the outflow pipe and into the drainfield, plugging up the drainfield and resulting in drainfield failure. In order to get your septic tank cleaned, you must first locate the main compartment2nd compartment lid of the septic tank and remove it.

The position of a septic tank lid and the number of lids on a tank varies depending on the year it was placed and the manufacturer.

If you prefer not to find and excavate the Septic Tank lids yourself, or if you are unsure of where the lids are placed, Express Septic Service may assist you with this task.

When looking at an as-built, keep in mind that it will only show the overall placement of the sewage system components, not the actual location of the septic tanks.

Septic Diagrams:

1000 Gallon Septic Tanks: This tank design, which was in use from around 1976 to present, will have one main lid and two smaller baffle covers on either end of the tank, as seen in the diagram below.

Two Compartment

From late 1976 until the present, a septic tank layout of 1125-1200 gallons was erected. It is possible for this tank to have two main 24′′ lids or two main lids and two little baffle lids at both ends of the tank right above the inlet and output baffles, depending on the manufacturer. If there are risers to the surface of the tank, you will be searching for two lids that look like this. If the tank is not risered, you will discover concrete lids with a diameter of 2-24″, as seen in the figure below.

Holding Tank

As an alternative to the traditional on-site sewage system, it is a good option. A holding tank is not the same thing as a septic tank. A holding tank is used to retain household waste and prevents any of its contents from leaking into a drainfield, whereas a septic tank is used to enable waste water to flow into a drain field. Concrete, fiberglass, and polyethylene can all be used to construct holding tanks. Depending on the location, holding tanks can be constructed above or below ground. Holding tanks must be pumped on a regular basis, depending on the amount of water and waste water used, as well as the size of the tank.

Most holding tanks are fitted with alarms that will ring when they are almost full, signaling the need for a pump to be installed as soon as possible. In the event that a holding tank is not properly pumped, waste water will back up into the home or spill onto the ground.

Pump Tank

Some homes may be equipped with a pump tank or a pump basin in addition to a septic tank. Typically, pump tanks are located underground near the septic tank; however, depending on the year the system was established, risers to the surface may be present, allowing for simple access to examine and repair the effluent pump for maintenance or if the pump has stopped operating. Before the effluent is pumped to the drainfield region, it is collected in a pump tank or basin from a septic tank or ATU (Alternative Treatment Unit).

See also:  How Does Septic Tank Not Overflow? (Correct answer)

It is necessary to configure the control floats such that a certain volume of effluent is discharged to the drainfield.

The pump then works to bring the level of wastewater back down until it reaches that of the off float setting.

When the alarm goes off, there is enough reserve storage in the pump tank to allow the homeowner to consume only a little amount of water until the problem with the system can be resolved and the alert turned off.

Aerobic Treatment Unit (ATU)

Several types of pump tanks and basins are used in conjunction with septic tanks in some households. In most cases, pump tanks are located underground near the septic tank; however, depending on the year the system was established, risers to the surface may be present, allowing for simple access to examine and repair the effluent pump for maintenance or if the pump has stopped functioning. Prior to pumping wastewater to the drainfield region, the effluent from a septic tank or ATU (Alternative Treatment Unit) is collected in a pump tank or basin.

It is necessary to adjust the control floats in order to send a certain volume of effluent to the drainfield.

The pump tank is also equipped with an alarm box, which is normally positioned in the basement, garage, or side of the house and which sounds when any of the components in the pump tank experience a problem or failure.

Restaurant Grease Trap

Almost every food service facility that serves food and washes dishes, including restaurants, cafés, coffee shops, delicatessens and bakeries (among others), will have an interior grease trap located near the sinks to collect grease from the sinks. They are available in sizes ranging from 20 to 50 gallons. Fatty acids, oils, and grease (FOG) are prevented from entering your drain pipe by a grease trap, which is a chambered compartment.

Grease flows into the trap, enabling the grease to solidify and float to the top of the trap while weighted solids fall to the bottom of the trap, allowing the liquid to flow out via the drain pipes and into the septic tank or into the city sewage.

Grease Tank Interceptor Service

A grease interceptor is a huge tank that may be situated outside of the structure on the ground level. They can range in size from a few hundred gallons to several thousand gallons. You will need two tanks if you have an exterior tank. The first tank will be a grease trap (tank), which will hold grease until it is removed. The garbage from the restrooms will be disposed of in a tank that is specifically dedicated for this purpose; if the facility is on sewer, the waste will be disposed of in the city sewage.

In addition to a simple cleaning rooter service utilizing an electric snake, we also provide hydro-jetting, which uses high pressure water to break away hardened grease and keep the drain from backing up.

This sort of mid-seam styleconcrete septic tankallows the pipe from the home to be routed to either of the tank’s side or center intake locations. The same choice is available for the tank’s outlet drainage pipe, which may be extended out to the leach field from either the tank’s side or middle outlet drainage pipe.

If you have any questions regarding the broad selection of sizes and styles of one and two-compartment septic tanks and accessories that we produce at our state-of-the-art plant, please contact one of our knowledgeable septic specialists at A.J Foss.

Frequently Asked Questions

  • Systems that are more traditional in nature include Concrete Chamber Systems (for anaerobic systems), Mound Septic Systems (an above-ground septic system with a drain field mound), Sand Mound or Sand Filter Septic System, Gravity Septic System (needs a gradual slope), and others.

What is the average cost of a 1250 gallon precast concrete septic tank?

Answer:In terms of septic tank prices, the typical retail price for a 1,250-gallon system is $1250 on the open market. The most important factors that influence the average price of residential septic tanks are the size of the house and the amount of water used per day (or the consistency of the flow of wastewater), which influences the gallons capacity of water flow dependent on the amount of water consumed. A five- or six-bedroom house will require at least a 1,500 gallon tank, if not a bigger tank; in contrast, a two- or three-bedroom house will require a smaller tank and, as a result, cheaper tank pricing.

What affects the average price of septic system installation by professional installers?

When it comes to septic tank expenses, a 1,250-gallon system will run you around $1250 on average at the retail level. Question: Home size and daily water consumption (or consistent flow of wastewater) are the most important factors that influence the average price for residential septic tanks. The size of the house and daily water consumption (or consistent flow of wastewater) have an impact on the gallons of water flow capacity based on water consumption. A five- or six-bedroom house will require at least a 1,500 gallon tank, if not a bigger tank; in contrast, a two- or three-bedroom house will require a smaller tank and, as a result, reduced tank costs.

  • Choosing the right septic tank (for example, precast concrete vs lighter fiberglass tanks)
  • A drainage field or absorption field of a certain size (which might have an impact on labor expenses)
  • It is necessary to consider the presence of adjacent water sources (which may need the conversion of traditional septic system designs to alternative systems). Norweco Singlair Wastewater Treatment Systems, for example, are aerobic systems that employ aerobic microorganisms to treat waste water.

Soil testing to establish the soil conditions is an additional cost of installation issue to take into consideration. Get in touch with skilled specialists to acquire reliable pricing estimates for your unique tank requirements.

What is the most common septic tank size?

In New Hampshire, the septic tank with a capacity of 1250 gallons is used. Among septic designers, it is the tank that is most frequently specified and used. It is the smallest tank permitted by the New Hampshire Department of Environmental Services, and it may accommodate a dwelling with up to four bedrooms.

Extra bedrooms would require an additional 250 gallons per bedroom. As a result, a septic tank of 1500 gallons would be required for a five-bedroom house.

Can you drive over a 1250 gallon size septic tank?

When it comes to driving cars or heavy machinery over a tank, the design rating is what decides whether you can. A.J. Foss makes three different types of septic tank installations: H-10 is designed for pedestrian activity and has a live load of 300 pounds per square foot plus a burial depth of 3 feet. HD is intended for burial depths up to 5 feet. The H-20 rating is for vehicular drive-over traffic up to a maximum burial depth of 6′ in the ground.

Is it ideal for high water table areas?

Answer:Our regular 1,250-gallon septic tank is constructed in two parts, with the seam running along the centre of the tank. Because the seam is located at the very top of the septic tank, our 1250 gallon monolithic septic tank is perfect for use in areas with a high water table or near bodies of water. Because the liquid sits underneath the cover, there is no risk of anything leaking in or out.

How much does a 1250 gallon concrete septic tank weigh?

In response to your question, our 1,250-gallon concrete septic tanks weigh about 11,500 pounds. Based on the specifications, wall thickness, floortop thickness, and rebar reinforcement used by different precast manufacturers, weights might vary somewhat.

How many bedrooms does a 1250 gallon septic tank support?

According to the state of New Hampshire, a 1250 gallon tank can maintain a four-bedroom house. Since the regulations were updated in 2012, it is the smallest tank size that may be specified on new designs for the first time.

  • A 1250 gallon septic tank is utilized in systems with up to four bedrooms. The most often encountered tank size in New Hampshire
  • The smallest tank we propose for use as a septic tank is the following: It is shipped pre-assembled to make installation as simple as possible

Why are steel tanks or plastic tanks generally not recommended?

Because it is durable, practical, and long-lasting, precast concrete continues to be the most popular material for septic tanks and systems. Plastic tanks and fiberglass tanks, which are made of lighter materials than concrete and appear to be a more cost-effective choice, might be damaged during the installation process. In the case of structural damage to a plastic or fiberglass septic tank, the tank may need to be completely replaced. Septic tanks made of plastic are only recommended for use with alternative sewage systems, such as Norweco Singulair aerobic septic systems, which use oxygen-loving bacteria in conjunction with an aerator to break down solid waste and produce cleaner wastewater effluent that can be discharged to a drain field.

a little about the author: The Andrew J. Foss, Inc. precast concrete firm was founded by my father in 1963 when he was just 19 years old. My precast education began at a very young age for myself. Everything I know about producing high-quality precast concrete goods, from septic tanks to concrete headwalls, was passed down to me by him. He also taught me that in order to be successful in business, you must provide a superior product and treat your customers the way you would like to be treated yourself.

Together with my brother Matthew, I am now the sole owner of our family-owned precast concrete firm, and we have used all we’ve learned from our father to launch the next generation of our family-owned precast concrete company.

Searchable platform for building codes

In other building occupancies, the liquid capacity of septic tanks must comply with Table H 201.1 (1) and Table H 201.1 (4), which are determined by the number of bedrooms or apartment units in dwelling occupancies and the estimated waste / sewagedesign flow rate or the number of plumbing fixture units as determined from Table 702.1of this code, whichever is greater. It is required that the capacity of any one’s septic tank and its drainage systems be restricted to the soil structure classification in Table H 201.1(2), as well as to the specifications in Table H 201.1.

In the case of SI units, the following is correct: 1 square foot equals 0.0929 m2, 1 gallon per day equals 3.785 liters per day Notes:1 Sizing sewage disposal systems in accordance with predicted waste and sewage flow rates must be performed as follows: a. waste/sewage flow rates of up to 1500 gallons per day (5678 L/day) are possible. Waste / sewage flow exceeding 1500 gallons per day (5678 L/day) Equals septic tank size (b) Flow 1.5 = septic tank size Flow 0.75 times 1125 equals the size of a septic tank (c) The secondary system must be designed to handle the entire flow rate per 24 hours.

Because of the large number of variables that must be taken into consideration, it is not possible to define absolute figures for waste / sewage flow rates for all circumstances.
