Frequently asked in Nashville-Davidson metropolitan government (balance)

What is the purpose of a septic tank?

A septic tank is a primary component of an on-site wastewater treatment system, crucial for many homes in and around Nashville not connected to the city sewer. It receives all wastewater, allowing solids to settle and fats to float. Naturally occurring bacteria then begin to decompose the organic waste, treating the liquid effluent before it moves to the drain field.

What is the average cost of a septic tank?

The cost for a septic tank in the Nashville area is determined by its size, construction material, and the complexity of installation. Factors such as soil composition and the necessary excavation depth on your property will also affect the overall price. For an accurate estimate tailored to your needs, it's best to request a quote.

How long do septic tanks usually last?

When properly maintained, a septic tank can provide reliable service for 20 to 30 years, and sometimes even longer. Regular pumping and avoiding the introduction of harmful substances are key to maximizing its lifespan. Protecting the tank from extreme weather conditions also contributes to its longevity in Tennessee's climate.

How often do septic tanks need to be emptied?

Generally, septic tanks should be pumped every 3 to 5 years. The specific frequency for your Nashville home will depend on the number of occupants and your household's water usage. Signs like slow drains or sewage odors might indicate a need for more frequent pumping.
