Eastern Municipal Water District (District) currently owns and operates the Temecula Valley Recycled Water Pipeline (TVRWP). The TVRWP conveys recycled water from the District's Temecula Valley Regional Water Reclamation Facility (TVRWRF) and Rancho California Water District's (RCWD) Santa Rosa Water Reclamation Facility to EMWD's Reach 4 Recycled Water Pipeline. The Reach 4 Recycled Water Pipeline conveys recycled water to EMWD's storage facility at the Sun City (SCRWRF) or to Lake Elsinore as make up water, and to Temescal Wash for discharge.
The District is in the final planning stages of expanding the TVRWRF from 18-million gallons per day (MGD) to 23 MGD capacity. The project is proposing to construct an additional recycled water pipeline which would parallel the existing 36-inch diameter segment of the TVRWP. The proposed project would provide adequate capacity to convey increased flows from the TVRWRF, at the same hydraulic conditions as at present. Five alternative alignments were considered for the new pipeline. The preferred alignment (Alternative 1B) is approximately 3.1 miles (16,500 linear feet) in length from teh TVRWRF to the connection point within the existing 48-inch recycled water pipeline, approximately 1,350 feet southeast of the intersection of Adams Avenue and Fig Street in the City of Temecula.
The proposed project also intends to make some improvements to the recycled water booster station at the SCRWRF to accommodate the increased flows in the Reach 4 Recycled Water Pipeline. The improvements wouldinclude installation of at least three additional pumping units; installation and relocation of associated electrical hardware; upsizing the existing 36-inch suction and discharge header piping system; and additional sound wall construction to meet area noise requirements.
