Eastern Municipal Water District – Temecula Valley Regional Water Reclamation Facility

Project Synopsis
CPM Partners provided services to Eastern Municipal Water District (EMWD) for the Temecula Valley Regional Water Reclamation Facility 23 MGD Expansion. This project is EMWD’s smallest of five reclamation plants; however, its capacity is the second largest.

Project Synopsis
The Temecula Valley Regional Water Reclamation Facility 23 MGD Expansion (TVRWRF) project provides an additional five million gallons per day (MGD) of treatment capacity, expanding the total permitted treatment capacity from 18 to 23 MGD of annual average flow. The construction involves an additional wastewater treatment process for preliminary treatment; primary treatment and fine screening; secondary treatment using a membrane bioreactor process (MBR); chlorine disinfection (Plant 3A); a rotary drum thickener; and additional modifications to existing facilities. To accommodate the facilities footprint, EMWD has pro-actively initiated a pre-negotiation with GE ZeeWeed for water treatment and reuse membrane bioreactor technology. This system was installed in a designated area located on the northwest corner of the facility that will accompany a solar grid to provide an alternative energy supply. The MBR will be the first treatment technology of its kind for the District. The intent of the MBR is not only to address the need for a small footprint, but also to use the new system as a pilot program to identify the advantages and disadvantages of the system. The experience from maintaining the MBR system will allow the District to determine if they would use the MBR technology for other future upgrades to the facility in lieu of the traditional treatment techniques that are currently being utilized at the TVRWRF.

Services Provided
