Septic Sewer System

To remain effective, aerobic treatment unit components need regular maintenance. Poorly maintained systems may not produce water as clean as desired.

For the best care for an aerobic treatment unit, follow the manufacturer's recommendations. Use these general guidelines as a basis for maintaining your system. They are divided into practices provided by a maintenance contractor, and those performed by the homeowner.

To select an aerobic unit, first determine the amount of daily waste­water flow from the home or small business. Then choose a Class I aerobic unit that can handle the amount of flow.

The Texas Natural Resource Conservation Commission maintains a list of Class I aerobic treatment units approved for sale in Texas.

The approved units are listed by company, model number, their rated treatment capacity and whether or not they require a trash tank in the treatment system.
