IWS was awarded a contract by the Tule River Indian Tribe to complete construction of the Wastewater Treatment Facility at the Tribes property in Porterville, CA. The Tribe in  conjunction with US Indian Health Services had a design completed for the overall system.

In addition to the installation of the packaged Ovivo® microBLOX™ MBR, the project included connection to the residential conveyance service line and  purchase and installation of a 96” diameter by 28ft deep duplex influent lift  station. The lift station conveys influent, via pipeline installed by IWS to a  75,000 GPD package MBR wastewater treatment plant and two 12,000 gallon equalization tanks.

The wastewater treatment facility and controls, installed by IWS, then conveys the treated water to an effluent discharge systems, WAS  pumps  and  dewatering  containers. The  treated  water  is ultimately  conveyed  to  a  300,000  gallon effluent storage tank prior to disinfection and dispersal.
