Septic System

A septic system treats domestic wastewater. The primary goal of a septic system is to prevent groundwater pollution.

A septic system consists of three main components: wastewater pipe, septic tank, and drainfields.

A septic system is planned, built and maintained by a septic engineer.

The wastewater pipe feeds into the inlet of the septic tank.

Water from toilets, sinks, showers, and dishwater flows through the wastewater pipe as it exits a house.

A septic tank contains a biological wastewater reclamation process. Wastewater from the wastewater pipe feeds into the septic tank inlet. Water is separated from the waste then the separated water flows into the drainfields through the septic tank outlet.

The drainfields are perforated pipes that restrict the flow of water into soil. The water is filtered as it passes through the soil.

The filtered water can then be reclaimed by the environment.

There are different types of drainfields for different environments. The necessary type is determined using a percolation test.

Drainfields failures are devastating. They are usually caused by grease or solids clogging the drainfields pipes. They can be prevented by installing effluent filters on the outlet of each septic tank.

Effluent filters can be installed on the outlet of a septic tank to prevent solids from entering the drainfields.

These prices include site evaluation, percolation test, and application/permit fees.

A cluster septic system with 20 connections can cost around $25,000.

A normal septic tank (1 connection) can cost around $10,000.
