Water Reclamation Plant No. 4 Non-Potable Water Improvements Project

Water Reclamation Plant No. 4 Non-Potable Water Improvements Project

The WRP 4 NPW Improvements Project would construct tertiary treatment facilities within the existing WRP 4 plant site to enable production of up to 10 MGD of non-potable recycled water for irrigation. CVWD has developed three phases to achieve 10 MGD production and distribution. Phase 1 would include construction and operation of a 1-MGD packaged cloth disk filtration system and an ultraviolet (UV) disinfection treatment plant as part of an overall treatment facility incorporating infrastructure expandable to 2.5 MGD. CVWD would construct a new reservoir serving as a regulatory structure within WRP 4 and repurpose an existing irrigation pipeline to deliver a blend of recycled water and canal water to customers located south of WRP 4. Phase 2 would incorporate additional equipment at WRP 4 to treat up to 2.5 MGD of tertiary treated recycled water, with onsite infrastructure expandable to 10 MGD, and construction of new distribution pipelines to deliver 2.5 MGD of recycled water. Phase 3 would increase treatment capacity at WRP 4 to up to 10 MGD. Similar to Phase 2, new recycled water delivery pipelines would be constructed to accommodate delivery of 10 MGD to agricultural customers.
