Perris Valley Regional Water Reclamation Facility DAS Hydrocyclone Pilot

The Eastern Municipal Water District is advancing a pilot project at the Perris Valley Regional Water Reclamation Facility to address operational constraints caused by ongoing rehabilitation work. The project will install temporary hydrocyclone skids and ancillary equipment designed to enhance activated sludge settleability through densified activated sludge technology, thereby improving the efficiency of the secondary treatment system. This intervention aims to maintain wastewater treatment capacity during facility shutdowns by reducing hydraulic and biological loading pressures, ensuring uninterrupted service throughout the rehabilitation phase. The initiative is specifically targeted at preserving system performance and preventing bottlenecks that could arise from reduced operational capability during critical maintenance periods. The primary beneficiaries are EMWD ratepayers, who will continue to receive reliable wastewater treatment services without degradation in quality or volume. The project is forecasted with a posted date of June 10, 2026, and is located in Perris, California, with Martha Vilchis, Water Resources Specialist Assistant I, serving as the point of contact for inquiries.
