What affects the price

About this service

The price for a new septic installation depends on several key factors. The primary drivers are the number of bedrooms in your home, which determines the tank size, and the results of your soil percolation test. If the ground requires a specialized treatment system, the total will be on the higher end of the spectrum. Costs typically sit in a broad range depending on these site 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 Lexington-Fayette

What is the purpose of a septic tank?

A septic tank serves as the primary treatment unit for wastewater from homes not connected to a municipal sewer system. It holds wastewater long enough to allow solids to settle into sludge and grease to rise as scum. The liquid effluent then moves to a drain field for further treatment in the soil. This is essential for rural and semi-rural areas of Lexington-Fayette.

What is the average cost of a septic tank?

How long do septic tanks usually last?

With proper maintenance, a septic tank system can last 20 to 30 years, or even longer. Regular pumping and avoiding harsh chemicals are crucial for longevity. The tank itself is quite durable. However, drain field problems can sometimes occur sooner if the system is overloaded or neglected. This is important for the unique terrain of Kentucky.
