Septic Tank Installation Guidelines – Ensuring Proper Placement And Function

A septic tank system is an essential part of any home. To protect groundwater from contamination, the system must be properly installed and maintained.

During installation, it is important to adhere to local regulations and follow the manufacturer’s guidelines. This will ensure that the septic tank functions as intended and remains watertight. Make sure to check out Septic Tank Services Near Me.

Ideally, the septic tank should be situated on high ground. This helps to prevent water seepage and minimize the risk of flooding. It is also important to consider the orientation of the septic system when selecting a location for the tank and drain field. If a septic tank is installed at an inappropriate angle, it may be subject to excessive rainfall and flooding of the drain field, which will lead to wastewater seepage and contamination of the surrounding soil.

A professional septic tank installer will complete a site assessment and ensure that the size and design of the septic system are appropriate for the property. This process includes conducting a percolation test, which involves digging a hole in the soil and measuring the rate at which the water drains from the hole to determine the soil’s ability to absorb wastewater. This information is used to design and size the septic tank, ensuring that it is not overloaded.

If you’re installing your septic tank, the manufacturer should provide a detailed manual that will guide you through the process. The manual will include a step-by-step guide and advise you of all the health and safety measures that should be taken.

To find the septic tank, look for surface clues in your yard, such as a depression in the soil or lush green patches of grass. It is also a good idea to leave a physical marker, such as a brick or large rock, near the septic tank to help you locate it in the future.

Lastly, review any inspection reports from the previous homeowner if you’re looking for information about your home’s septic tank and drain field. These reports typically contain the tank’s location and a diagram or map of the tank’s location and connections to the house.

Once you’ve found your septic tank, it is important to maintain proper maintenance of the system. Avoid dumping waste in the drain field, including cigarette butts, coffee grounds, egg shells, cat box litter, sanitary napkins, cotton swabs, and discarded medication. It’s also a good idea to get your septic tank pumped regularly.

Drainage Field

The drain field, sometimes called the leach field, is a crucial element of your home’s septic system. It is the part of your septic system that treats wastewater by filtering, chemical reactions, and decomposition by soil microorganisms before it is released back into the environment. It is the last step of septic tank treatment and a large part of why homeowners choose a septic system over other methods of waste disposal.

To ensure a well-functioning septic tank, it’s important that you properly install the drain field. This means ensuring the drain field is sized to correctly treat the volume of effluent that is produced daily. This is determined by several factors including the size and use of your home, the type of septic system you have, the soil’s percolation rate, and more.

If you’re not sure how to size and install your septic tank drain field, it’s highly recommended that you work with a professional. Choosing a septic installation company that has experience and is familiar with local regulations and requirements will help you get the most out of your septic system for years to come.

Once your septic tank is installed and connected to the drain field, you’ll need to backfill the area around it. It’s important to follow the manufacturer’s guidelines for this process, as improper backfilling can damage your septic system. Generally, you’ll need to use a mix of gravel or crushed rock and soil. If you’re not certain what the best backfill mixture is for your septic tank, contact your installer for advice.

In addition, you should never plant anything with deep roots near your septic tank. This is because the tank may have leaks or cracks and planting anything with roots could cause them to grow into these areas and worsen the problem. It’s also not a good idea to drive cars or other heavy vehicles over the drain field, as this can damage it and put your family at risk of exposure to harmful toxins.


When installing a septic system, the right bedding is an important factor to ensure proper function and prevent issues with clogging. The bedding is the layer of soil around the tank that absorbs and holds wastewater. The bedding must be free of clods, rocks, and other debris to avoid settling that can damage the septic tank or drain field.

The right soil type must be selected as well. A percolation test is essential to determine the soil’s ability to absorb and treat waste. This information is crucial to the design and size of the septic system.

Once the location is chosen and the necessary permits are obtained, excavation can begin. A hole that is twice to three times the size of the septic tank will need to be dug. The location should be on well-drained soil, away from water sources, and wells, and within the recommended distance from the home depending on your area’s regulations. Homeowners should also refrain from placing structures such as sheds or patios over the drainage field as this can restrict airflow and disrupt the natural sewage treatment process.

Once excavated, the septic tank will be lowered into the hole and the necessary pipes will be run from the house to the septic tank and the absorption field. During this time, it is essential to check for any cracks in the tank and verify that the tank is watertight.

To do this, the septic tank must be filled with water and any loss of water over 24 hours should be measured. The septic tank must also be tested to ensure that it is insulated.

After the tank is installed, a riser should be placed over the inlet and outlet pipes to allow for future access and inspection. It is recommended that you choose a professional who has certifications to help ensure that your septic system is designed and installed properly.

Once a septic tank is installed, it should be properly backfilled and graded to slope away from the tank to reduce groundwater seepage and erosion. The backfill should be tamped in lifts of uniform depth increments to eliminate any voids that can lead to settling and the need for future repairs or replacement.


The septic tank system provides homeowners with the opportunity to safeguard their water sources and provide wastewater treatment right on their property. With a properly installed and maintained septic system, homeowners can avoid costly repairs and maintenance costs while enjoying the benefits of efficient waste management. However, installing a septic system is not something that homeowners should try on their own. A septic tank installation requires professional knowledge of local regulations, state and federal requirements, and the best practices for excavation and bedding procedures.

Once the septic tank is in place and the plumbing connection is made, the drain field must be connected to it. This process involves digging a large area and filling it with gravel or another porous material. The drain field then needs to be covered with soil and grass to blend in with the surrounding landscape.

It is important to ensure that the inlet and outlet tees are properly configured. This is because these tees allow wastewater to flow into and out of the septic tank without any solids entering the absorption field, which can quickly clog it.

To prevent this, the inlet and outlet tees should be set several inches below the top of the scum layer. This allows hydraulic pressure to force the wastewater up into the septic tank and out through the inlet tee each time it is flushed.

The septic tank should also be located as far away from any homes or structures on the property as possible. This will help to keep the system functioning properly and reduce the amount of time that it must be pumped. The tank should also be as high off the ground as possible to minimize surface flooding and to provide a safe working environment.

Homeowners should map out the septic tank and other system components or mark them with permanent stakes to make it easy to access them when performing home maintenance and yard work. This will help to prevent accidentally damaging the septic tank or other components when using vehicles or machinery such as a mower. It is also a good idea to avoid parking or driving heavy equipment or vehicles over the drain field, as this can compact the soil and cause damage.
