An underground concrete structure known as a septic tank works to treat liquid waste materials. Underground construction is used to build septic tanks. The depth of septic tanks in Reno NV is determined by several factors when installing the tank.

Depth of a Septic Tank

Septic tank parts, including the lid, are typically buried 4 inches to 4 feet underground. To find its boundaries and label the circumference, use a metal probe. If you cannot locate the lid by probing, you should be able to find it by shallowly excavating along the tank’s edge with a shovel.

Factors Determining The Septic Tank Depth

1. Sewer Line Depth

The depth at which the lowest sewer line exits the building that the septic tank serves is known as the sewer line depth. The tank will be lower than the building’s outgoing waste pipe since we use gravity to transport sewage from the house to the septic tank.

A deep septic tank is not the best option if the water table is high. For better absorption, you may require to use more soil. A high water table leads to mound formation, similar to an above-ground drain field.

3. Site Conditions

The spot where the contractor discovered site conditions acceptable for burying the septic tank determines the depth. The site conditions include shape, rocks, and impediments. The tank may be situated at a different location if a site has bedrock or boulders near the surface.

4. Tank Type

The tank type helps to decide the tank depth. Many septic tanks are designed to retain up to two to three feet of earth on top. Therefore, if the tanks are positioned deeper, the manufacturer’s guarantee will be spoiled.

5. Soil Type

The depth of a septic tank depends on the soil’s composition. High water tables are regular in areas with a lot of clay. Hiring a professional to identify the soil type is a better decision because they recommend a septic tank depth based on that information.

6. Sewage Ejector Pump Or Grinder Pump System
