Does homeowners insurance cover septic tank collapse?

Yes, your septic tank is considered part of your home and would be covered by the dwelling coverage portion of your home insurance in the event that it is suddenly damaged.

Can you repair a plastic septic tank?

Plastic septic tanks are easier to carry and install than concrete tanks. Luckily, plastic-welding the septic tank will fix the crack and prevent the crack from growing. Depending on local building ordinances, you may be able to repair the tank yourself saving you hundreds of dollars.

How do plastic septic tanks work?

Septic tanks work by allowing waste to separate into three layers: solids, effluent and scum (see illustration above). The scum, composed of waste that’s lighter than water, floats on top. The middle layer of effluent exits the tank and travels through underground perforated pipes into the drainage field.

Design parameters for a septic tank include the following: Septic tank design specifications are discussed in this model septic design regulation, which includes requirements for septic tank size, septic tank cover access, septic tank characteristics, steel septic tanks, tanks for aerobic septic systems, and other related details. Septic tanks are used to collect and treat wastewater.

For this topic, we also have anARTICLE INDEX available, or you may check the top or bottom of the page.

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
4 1,250 34
5 1,500 40
6 1,750 47

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 coversshall always be accessible.

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.

  1. Baffles must be made of a long-lasting material that is resistant to corrosion, deterioration, and cracking, among other things.
  2. Tank systems with many chambers and tanks must be built to allow for the venting of tankgases as well.
  3. This will ensure that the leveling and bearing are correct.
  4. (viii) Between the inverts of the inlet and outflow pipes, there must be a minimum elevation difference of two inches.
  5. 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

Additionally, septic tanks made of fiberglass or polyethylene (plastic) must comply with the following specifications: I Fiberglass or polyethylene septic tanks should not be constructed in regions where the groundwater level can rise to the level of the bottom of the septic tank. The installation, bedding, and backfilling of Fiberglass or polyethylene septic tanks must be done with extreme caution in order to avoid damage to the tank walls and other components. The installation instructions provided by the manufacturer must be followed to the letter.

If the tank is transported to the site in pieces due to its size, all joints must be sealed with watertight gaskets and all joints must be inspected for water tightness after installation and before backfilling is completed.

(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.

Septic Tanks – Fibreglass Versus Plastic

Fibreglass is rigid and does not bend. The main problem with many plastic tanks is that they are not sturdy enough, and if the groundwater level is greater than the tank’s base when it is emptied, the tank will deform and become unfit for function. Because groundwater pressures can be quite high, some distort even when completely full. As they bend, always inwards, the volume of the device is substantially decreased, rendering it unable to function correctly. Lids are no longer a good fit. In addition, drain connections snap off, forcing drain spigots to bend downward, causing the drains to lose their gradient and the system to “back-up.” Both chambers can overflow into each other when the internal baffle walls become disconnected from the walls of the other chamber.

  • In the photograph below, you can see the deformation that can occur when low-quality plastic systems are put in moist ground conditions.
  • In this yard, there were 50 old septic tanks that had been scrapped.
  • MDPE was never meant to be used for subterranean installations, yet it is quite inexpensive to purchase and install.
  • By immersing the septic tank in a pool, you will not be able to determine its strength.
  • Groundwater is unable to do so because it is trapped by the weight and density of the earth above it, resulting in a huge rise in pressure.
  • Because concrete is not watertight, groundwater works its way through the concrete and bends the tank regardless of how well it is constructed.
  • The only safe approach to install a plastic septic tank, according to our expertise, is to construct a watertight chamber for the tank to be placed in.
  • Any other technique of installing a plastic septic tank runs the danger of distorting it, but this operation is quite costly.

This premium one-piece fibreglass structure comes with a 25-year guarantee and is built to last. The Class 1Crystal Septic Tankoption may be erected with a gravel backfill, even in places with high groundwater levels, without the risk of deformation or cracking, according to the manufacturer.

Plastic Sewage Treatment Plant Tanks

The EN12566-3 Tank Strength Test is only required for the CRUSH strength and is not required for any other strength. When the tank is subjected to this test, it is weighted on top with increasing weight until it collapses. This test does not accurately simulate the impacts of groundwater since groundwater exerts pressure from all directions, including from the tank’s base and the tank’s sidewalls. Although there is an EN12566-3 test for groundwater pressure resistance – the WET PIT TEST – unfortunately, this test is OPTIONAL, and many manufacturers, particularly those who are unsure about their tanks, prefer to forego this crucial test!

The tank is covered in gravel and water is pushed into the gravel to simulate groundwater pressures.

Some tank manufacturers claim that their tank has passed a wet pit test even if it has only been partially submerged in water throughout the testing process.

This does not meet our standards, in our opinion.

  • Is the tank in possession of an EN12566-3 Wet Pit Certificate? What was the depth of the water surrounding the tank? How long was the tank subjected to testing?

Because you have no way of knowing what your groundwater will do to the tank, don’t buy their wastewater treatment plant if they refuse to inform you. In order to serve as an example, the VORTEX sewage treatment facility has been awarded the Wet Pit Certificate. Over a three-week period, it was immersed in groundwater to a level above the entrance pipe (the water level was just 300mm below ground level).

» Septic Tanks

Engineered below-ground septic tank solutions are a specialty of Premier Plastics Inc., which has 25 years of experience in the design and installation of these systems. The resistance to compression buckling or pressure from the outside in is a critical design factor of poly septic tanks for below-ground use. In contrast to above-ground tanks, where the pressure is applied from the outside in, underground tanks apply pressure from the inside out. The tensile strength of the material is the most important design consideration.

Below-ground tanks are available in a variety of shapes and sizes.

This is something that no other tank design can boast.

  • Pre-plumbed connectors for 4″ sewage pipe are provided at the inlet and output points. There are also two room dividing walls that may be used if necessary. During the installation procedure, there is no requirement for water ballast. Polyethylene septic tanks are formed in a single piece and are completely waterproof right out of the factory
  • They are also quite durable. Various forms of riser pipe can be accommodated through the access apertures.

Take the time to read the Installation Instructions and to return the warranty card that was included with each tank.

THE BASICS

Traditionally installed septic systems are composed of two major components: the tank itself and a soil absorption system. Tanks are waterproof containers that can retain wastewater discharged from the home for up to 48 hours, providing enough time for the scum and sludge to settle out of the wastewater. It is the responsibility of the homeowner to ensure that the septic tank is properly maintained and that the effluent is not released into the environment. Septic systems are required for the treatment of sewage in regions where there is no connection to major sewage pipelines provided by the local government or private organizations.

“SEPTIC” REFERS TO THE ANAEROBIC BACTERIAL ENVIRONMENT THAT DEVELOPS IN THE TANK AND DECOMPOSES OR MINERALIZES THE WASTE THROWN INTO IT!

THE TANKS

In most cases, a tank is made up of one or more concrete or plastic sections with capacities ranging between 1,000 and 2,000 gallons each. On one end, the tank is linked to the input sewage pipe, and on the other, the tank’s exit, it is connected to a septic drain field. In most cases, these sewage pipe connections are built with a plastic T-shaped pipe made of PVC plastic (with older tanks, the connection may be concrete). Tanks are often divided into two sections by manhole-like coverings that serve as access points.

Water enters the tank through the first chamber, where solids settle and scum float, allowing solids to settle and scum float.

Following its passage through the separating wall, the liquid component enters the second chamber, where it undergoes additional settling.

CONCRETE SEPTIC TANK:

The trench system is comprised of shallow, flat excavations that are typically 1-5 feet deep and 1-3 feet broad, with a maximum depth of 1 meter. The excavated space is often filled with a porous media, such as gravel, that is 6 inches or more in depth. The following step involves the placement in each trench of a layer of perforated distribution pipes, which is followed by a semi-permeable barrier (typically construction paper or straw), and lastly the system is filled with soil.

A three-step bacterial respiration process that happens in the absence of oxygen is referred to as anaerobic process. Effluent is defined as the cleared, partially treated liquid that exits a septic tank after it has been partially treated. Large particles have been separated using a variety of methods, including settling, flotation to coagulate in a grease and scum layer, and filtering. Effluent is discharged from the tank and into the absorption/treatment system, where it is further treated.

Septage is a combination of solid wastes, scum, sludge, and liquids that is pumped out of septic tanks and into the environment.

Sludge is solid waste that has accumulated at the bottom of a septic tank. Sludge is a kind of organic waste that is semi-solid. Sources:

Concrete Septic Tanks Are Probably The Best Option — Build With a Bang

Concrete Septic Tank with a Capacity of 1000 Gallon When it comes to septic systems, whether you’re in the market for a new system or just need a replacement tank, you’ve arrived to the perfect location. As part of our recent investigation into different types of septic systems that are available for your house, we decided that it would be a good idea to also investigate the many types of septic tanks now available on the market. The following are the three most common types of septic tanks that are easily accessible for installation: When constructed properly and maintained on a regular basis, the majority of concrete septic tanks may endure for up to 40 years.

  1. Waste flow, home size, square footage, number of bedrooms, number of bathrooms, and a few other factors are taken into consideration in septic tank size recommendations and charts.
  2. Septic tanks are available in a variety of sizes, and you can even obtain tanks that are smaller than 1000 gallons; however, we recommend that you go with a tank that is at least 1000 square feet in size.
  3. Consult with a licensed expert before purchasing or installing any equipment if you’re going to install a new septic tank or septic system for the first time.
  4. ” A few of states are now requiring 1000 gallon tanks as the minimum size requirement.

The popularity of the concrete septic tank can be attributed to its strength, weight, and longevity. For more precise information on durability, concrete septic tanks that are correctly constructed have a lesser probability of breaking, cracking, or floating.

Check out these 6 septic systems available for your home.

When constructed properly and maintained on a regular basis, the majority of concrete septic tanks may endure for up to 40 years.” No matter which option you choose, keep in mind that a home’s septic system should be cleaned, examined for leaks, and professionally maintained every 3-6 months in order to keep it healthy and running correctly for the owner. There are a variety of tables and suggestions for septic tank sizes based on waste flow, home size, square footage, number of bedrooms, number of bathrooms, and even a few additional considerations.

  1. You may purchase septic tanks in a variety of sizes, including tanks that are less than 1000 gallons; however, we recommend that you stick with a tank that is at least 1000 square feet in size.
  2. If you’re going to install a new septic tank or septic system, make sure to contact with a licensed professional before purchasing or installing any of the equipment.
  3. ” A few of states now mandate 1000 gallon tanks as the bare minimum size requirement.
  4. In addition to its strength, weight, and durability, the concrete septic tank is quite popular.

Heavy Duty Options

Many tanks are also available in “high duty” configurations, which generally have a reinforced top and bottom. Purchasing the heavy-duty version may be a wise decision in the case that a vehicle, agricultural equipment, or other large piece of heavy machinery passes over the tank area.

Installation Requirements

There are also “high duty” versions of several tanks that often contain a reinforced top. Purchasing the high-duty version may be a wise decision in the case that a vehicle, agricultural equipment, or other large piece of heavy machinery passes over the tank.

Lifespan and Durability

The method by which the concrete septic tank was constructed will have an impact on its long-term function. High-quality concrete, adequate water sealing, and the use of structural steel goods such as mesh and rebar will provide additional support, strength, and structural integrity to the structure. Keep in mind that concrete septic tanks are more prone to cracking and leaking than their plastic and fiberglass equivalents when exposed to exceptionally cold temperatures and pressures. Most concrete septic tanks have a lifespan of up to 40 years if they are constructed properly and serviced on a regular basis.

1000 Gallon Concrete Septic Tank

Septic tanks of 1000 gallon capacity or larger are the most typical size for household usage, as they can readily fit most 0-3 bedroom dwellings. Size Weight: The weight of each concrete tank is different. Some of the most common 1000 gallon concrete precast tanks are around 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs.

Others are approximately 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Here are some examples of Jensen Precast projects completed in various cities around the United States. Approximately 9 1/2 feet in depth, however this varies according on the distributor, state, and local statutes.

1250 Gallon Concrete Septic Tank

Generally speaking, a 1250 gallon tank is a good choice for mid-size homes with 3-4 bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. 1250 gallon concrete precast tanks are typically 5′ 9″ x 8′ 6″ x 5’8″ in size, with some of the more common models being 5′ 9″ x 8′ 6″ and others measuring 5′ 8″. The typical weight of a 1250 gallon concrete tank is 11,000 lbs, however this might vary depending on the distributor.

Inlet Baffles

When installing a septic tank, an inlet baffle should be put on the inlet part closest to the point at which the sewer tank joins from the house structure to the tank. Due to the fact that it prevents scum and oils from blocking the entrance pipe, the inlet baffle is critical to the overall health and effectiveness of the septic system. The intake baffle is a bottle neck that is especially designed to do the following:

  • In order to prevent the breakdown process from being disrupted, it is necessary to slow the effluent entering the septic tank. A fast rate of inflow of effluent might cause problems by mistakenly combining the settled solid waste with oils, scum, and effluent. Make sure no sewage gases are allowed to enter the sewer line. These gases have the potential to infiltrate back into a home or structure, generating a foul odor.

Outlet Baffles

Every septic tank should be equipped with an exit baffle that is connected to the discharge line. The outlet baffle functions as a bottle neck in the same way as the inlet baffle, but in the opposite direction. It is meant to:

  • It is recommended that every septic tank have an output baffle connected to the outflow pipe. This baffle operates as a bottle neck, and it functions in a similar manner as the inlet baffle, but in the opposite direction.

All effluent from the septic tank must be clear of solid waste before it may be discharged. Other than that, the solids and oils will pollute the drain field/leach field and result in backups and pollutants entering the surrounding environment. Ensure that your baffles are correctly built and that they are not in need of repair by consulting with a licensed septic technician before doing anything else. Septic tanks made of fiberglass or polyethylene (polyethelyene) are also a suitable option, especially if your location has specialized environmental requirements.

Mobility

There must be no solid waste in any of the wastewater discharged from the septic tank. Otherwise, the sediments and oils will pollute the drain field/leach field, resulting in backups and the release of pollutants into the atmosphere. Ensure that your baffles are correctly installed and that they are not in need of repair by consulting with a licensed septic technician before doing anything else!

Alternatively, fiberglass and polyethylene (polyethelyene) septic tanks are a viable option, particularly in certain local circumstances. septic tank made of heavy-duty polyethylene material

Cost Effectiveness

If you’re seeking for a less expensive alternative to concrete, fiberglass and polyethylene (polyethylene) are excellent choices. The majority of fiberglass and plastic septic tanks are thousands of dollars less expensive than concrete septic systems.

Durability

When compared to a concrete septic tank, both plastic and fiberglass septic tanks have a lower likelihood of breaking. Furthermore, because fiberglass and plastic are nonporous materials, there is typically no problem with tree or bush roots growing into the tank and generating leaks as a result of root damage. Having said that, due to the tank’s smaller profile and lighter material composition, caution must be used during installation because heavy gear might easily harm it. Tanks made of fiberglass or plastic can be destroyed in the same way as concrete tanks can if too much weight is placed on the surface above them.

Despite the fact that plastic and fiberglass tanks are quite resilient, they can nonetheless leak under specific circumstances.

The size of the lot, the position of the tank, the amount of ground water, and the weather can all influence the selection.

Float

Plastic and fiberglass have a number of advantages, but they can also be troublesome. Yes, the lightweight character of these materials makes them perfect for installation, but same lightweight nature also results in a high level of buoyancy in the final product. It is possible that during a storm, a plastic or fiberglass tank can get dislodged from its couplings, causing considerable damage to the septic system and the homeowner’s property, with repair costs in the hundreds of dollars. A simple solution is to place a concrete slab on top of the tank to help weigh it down.

If you reside in an area with a high groundwater table, consult with a specialist to ensure that the higher water table will not cause harm to your fiberglass or plastic tank.

Precast Concrete Septic Tanks vs. Plastic Septic Tanks

When it comes to selecting a septic tank for your property, there are several alternatives to consider. First and foremost, you want to be sure that the tank you choose has the appropriate capacity for your home. After that, you’ll want to be certain that you select a tank that will give years of dependable service for you and your family members.

A precast concrete septic tank is the most suitable option. Precast septic tanks provide several advantages over other types of tanks, such as plastic, steel, or fiberglass. Because of this, concrete septic tanks are required in a large number of cities and municipalities.

The Benefits Of A Precast Septic Tank

  • The tanks weigh a great deal. While this may be considered a disadvantage by some, we feel it is one of the most significant advantages of using carbon fiber over other materials. Because of the weight of the precast concrete septic tank, it will never “float” to the surface, which is something that certain lesser weight tanks may accomplish in certain scenarios. Precast concrete septic tanks have a specific gravity of 2.40, which makes them more resistant to buoyant forces than other septic tank materials. HDPE has a specific gravity of 0.97, which is very high. For anchoring structures composed of more buoyant materials, further labor-intensive and time-consuming on-site preparation is required. When selecting a septic tank for your property, it is important to consider the following factors: Precast septic tanks do not rust, which is a major concern. Steel tanks, as well as portions of some plastic and fiberglass tanks, are extremely susceptible to corrosion and failure. Unlike traditional concrete, precast concrete gradually gains strength over time. Other materials, such as steel or high-density polyethylene (HDPE), can degrade and lose their strength. The contents of precast concrete storage tanks may be pumped out without the risk of the tank collapsing. The process of installation is basic and uncomplicated. Shea Concrete offers a staff of tank installers that have completed hundreds of tank installations in the past. We are well-versed in site preparation and are capable of overcoming virtually any installation challenge. In addition, we have vehicles that are fitted with hoists and can even crane a tank over a house when necessary
  • Concrete, along with water, is the most widely utilized building material on the planet. This natural substance is non-toxic, ecologically safe, and comprised entirely of natural materials, making it an excellent choice for septic tanks. Concrete is employed in a variety of applications throughout the country and has no negative impact on the quality of groundwater or surface water. During the installation process, plastic tanks are susceptible to damage. In most cases, the installation process is to blame for tank failures
  • Precast concrete tanks can be made watertight if they are manufactured in accordance with the National Precast Concrete Association’s “Septic Tank Manufacturing” Best Practices Manual and/or ASTM C 1227, “Standard Specification for Precast Concrete Septic Tanks.” In accordance with these industry standards, which Shea Concrete adheres to, the required processes to be followed during the fabrication of waterproof tanks are specified. It is never acceptable to drive an automobile over a plastic storage tank. This may set restrictions on the location of the tank and leaching area on your land.

Why A Concrete Septic Tank?

Concrete septic tanks are preferable than fiberglass or plastic septic tanks because they are waterproof and heavy duty, making them the preferred storage vessel for on-site sewage storage and treatment over the other materials. In the United States, there are over 40 million septic systems in operation. Septic systems rely on the soil surrounding the septic tank, which is the major component in a septic system, to filter the wastewater discharged from the tank. Concrete septic tanks are also well-known for the following characteristics, in addition to the advantages described above:

  • 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.
