About this service

When planning for a septic project, remember that you are paying for both the equipment and the labor. The tank itself is just one part; you also have to pay for the excavation, piping, and drain field installation. The total amount is typically influenced by the depth of the water table and the materials used for the tank. Getting a professional site assessment is necessary to understand your specific needs. Exact pricing confirmed free on the call.

Summer often means more houseguests and increased water usage, which puts extra demand on your septic tank. With more showers and laundry loads, it is easier for a tank to reach capacity. If you have guests coming over, consider a pump-out beforehand to avoid an inconvenient backup during your family gatherings.

Frequently asked in Nashville-Davidson metropolitan government (balance)

What is the purpose of a septic tank?

A septic tank is a crucial component of an on-site sewage treatment system. Its main purpose is to collect all household wastewater, where solids settle to the bottom and scum floats to the top. Bacteria in the tank begin to break down the organic matter. The liquid effluent then flows to a drain field for further treatment before returning to the environment.

What is the average cost of a septic tank?

How long do septic tanks usually last?

With regular maintenance, including timely pumping and inspections, a septic tank system can last for 20 to 30 years, and sometimes even longer. Proper care is essential to prevent premature failures and costly repairs. Neglecting maintenance can significantly shorten the lifespan of your system, so staying on top of it is key.

How often do septic tanks need to be emptied?

Septic tanks generally require pumping every 3 to 5 years. However, this interval can change based on the number of people in your household and your overall water usage. For residents in Nashville, it's advisable to consult with a professional to determine the most appropriate pumping schedule for your specific needs to ensure optimal performance.
