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 Jacksonville

What is the purpose of a septic tank?

A septic tank is the initial stage of wastewater treatment for homes not connected to a municipal sewer system. It receives all household wastewater, allowing solids to settle as sludge and lighter materials to rise as scum. Bacteria present in the tank begin to decompose the waste. The liquid effluent then flows to a drain field for further filtration in the soil, protecting Jacksonville's water sources.

What is the average cost of a septic tank?

How long do septic tanks usually last?

When maintained properly, a septic tank system in the Jacksonville area can last between 20 to 30 years, and sometimes even longer. Regular pumping and avoiding the disposal of non-biodegradable items are crucial for longevity. Neglecting maintenance can significantly shorten the lifespan of your system. Understanding these needs is key.

How often do septic tanks need to be emptied?

For homes in Jacksonville, it's generally recommended to have your septic tank pumped every 3 to 5 years. This frequency depends on the number of people in your household and your water usage. Using a garbage disposal might require more frequent pumping. Regular pumping prevents solids from building up and damaging the drain field.
