Septic Tank Effluent Filters

Septic tanks are designed to retain solids that accumulate over time. Some of these solids are byproducts of the waste treatment process, while others are materials that may not be capable of being processed, such as human hair. The solids must be retained in the septic tank and not released to the drain field. Excessive discharge of solids to the drain field can cause it to plug and lose efficiency in the treatment process and the dispersal of the effluent. If the problem persists, the drain field may need to be replaced.

Septic tank effluent filters are an inexpensive way of preventing solids from being discharged into the septic field. They are usually installed at the septic tank outlet, where solids that may be discharged from the tank are collected. A filter may not be necessary if the septic tank is maintained correctly, including frequent inspection for solid accumulation and removal.

If you are considering using a septic tank effluent filter, check with your local public health authority to determine their installation and use requirements. Some authorities may require certification to NSF/ANSI 46: Evaluation of Components and Devices Used in Wastewater Treatment Systems.
