The Norweco spray irrigation system provides an alternative for dispersal of treated wastewater from a residential treatment system. It consists of any Norweco wastewater treatment system with the Service Pro WASP control center. Disinfection is achieved with Blue Crystal disinfecting tablets or an AT 1500 UV disinfection system. Treated effluent flows into a pump chamber followed by a pressurized spray irrigation unit or units. It can be used as a disposal option that can also effectively reclaim treated wastewater for irrigation purposes, according to the company. 800-667-9326; www.norweco.com.
