Zoeller Pump’s Turbine STEP (Septic Tank Effluent Pump) System is designed for use in a septic tank as an alternative to a separate pump tank. With a turbine effluent pump, float system, and effluent filter set packaged in a polyethylene vault, it is ideal for use on new construction or repair sites when gravity flow is not an option and higher total dynamic head is required. The system is also useful in low pressure pipe applications, sand filters, and other high head applications. Each can be equipped with a control panel for use in either demand dose or timed dose applications.
