Do You Need a Septic System Filter?


Do You Need a Septic System Filter?

Septic systems are private, self-contained waste treatment systems. They are often used to treat household waste for rural homes when city or county sewer lines are not available. The system incorporates a holding tank and leach field to process the waste. As the waste breaks down, solids remain in the tank while the greywater or effluent is discharged into a leach field where it is absorbed by the surrounding soil.

Septic Tanks 101

A septic tank filter is designed to protect the absorption or leach field of a septic system. The most basic type of wastewater effluent filter is a basic tee and filter design that is installed at the septic tank outlet. The installation is most often handled by a plumbing professional.

The primary function of a septic tank filter is to provide additional filtration and treatment before the effluent/wastewater reaches the leach or drain field. The filter reduces the chance that solid materials will enter the drain field, which will diminish its draining capacity and potentially lead to future repairs or problems.

Where Do Filters Come In?

Although most large solids and grease remain in the tank as floating scum or settle to the sludge layer at the bottom, smaller particles remain suspended in the middle layer that can work their way into the leach field. This can lead to premature clogging of the leach field system resulting in its repair or replacement.

A septic system filter catches and reduces the amount of these smaller particles preventing them from entering and damaging the drain field and extends its life as a result.

To reduce or prevent the chance of septic absorption failure, install a septic effluent or greywater filter to the septic tank tee. Common installation involves connecting the effluent filter within the tank system. However, another option is to install the septic filter outside the tank in a separate chamber that's close to the septic tank. The outside chamber must be installed close to the septic tank, upstream from the drain field.

The answer to the question "Do I need a septic tank filter?" is two-sided. No, you can get by without one and yes, it is wise to install one. Your septic will function normally without an effluent or wastewater filter. However, if your intentions are to reduce premature repair and replacement of the leach field, then you should definitely install an effluent/wastewater filter.
