Quail Valley Sub-Area 4 Project

The Quail Valley community is situated within the service area of the Eastern Municipal Water District (District). Quail Valley has experienced ongoing failures of private septic system that pose a threat to public health and water quality, both within the community and downstream in Canyon Lake. As a vital water source, residential area, and recreational destination, Canyon Lake serves the public in multiple capacities. In response to these challenges, the District and other key stakeholders—including Riverside County, the California Department of Public Health, the Elsinore Valley Municipal Water District, the City of Canyon Lake, and the City of Menifee—have collaboratively explored long-term solutions. The goal of this multi-agency effort is to implement a comprehensive, community-wide sewer collection system that would protect water resources, improve public health, and enhance the overall quality of life for Quail Valley residents. The proposed project seeks to establish a robust and comprehensive wastewater collection and conveyance system that provides consistent and reliable service to all Quail Valley Subarea 4 residences consistent with all established District standards, while also safeguarding public health, public water resources, and enhancing the overall well-being of the Quail Valley and Canyon Lake communities. The proposed project would construct approximately 10 miles of 8-inch and 12-inch polyvinyl chloride gravity main pipe, approximately 1.1 miles of force mains, 247 manholes, 37 connector pipes, one regional lift station, and four smaller lift stations (LS-2, LS-3, LS-4, and LS-5). The regional lift station (LS-1) would convey the majority of wastewater flows originating from Subarea 4. To connect Subarea 4 to the regional lift station, 37 connector pipes would be installed to link streets, thereby facilitating gravity flows. To accomplish this, connector pipes would be required to traverse private properties. Gravity flows cannot be fully achieved in the northwest portion of Subarea 4 due to varied topography. To adjust to this, lift stations LS-2 through LS-5 would pump wastewater via a shared force main to Collection Manhole 2, located at the intersection of La Bertha Lane and Mountain View Place, before ultimately discharging to LS-1. From LS-1, flows would be pumped to Collection Manhole 1 located at the intersection of Wells Place and Goetz Road. Collection Manhole 1 would connect to sewer infrastructure in Goetz Road. Construction is planned to be carried out in eight phases, to be implemented over an approximately 20-year period.
