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

The Coachella Valley Water District is advancing the Water Reclamation Plant No. 4 Non-Potable Water Improvements Project to expand non-potable recycled water production for irrigation purposes, with a long-term goal of reaching 10 million gallons per day across three phased expansions. Phase 1, currently at 60% design, will deliver 1 MGD of treated water through new distribution pipelines to three major agricultural customers south of the plant, with final design expected in early 2026, construction bidding in spring 2026, and completion targeted by the end of 2027. Phase 2, scheduled from 2028 to 2030, will increase capacity to 2.5 MGD by expanding tertiary treatment infrastructure and adding distribution lines to serve nearby customers. Phase 3, envisioned between 2031 and 2045, will depend on post-Phase 2 demand analysis and may scale production up to the full 10 MGD target, contingent on funding availability and regulatory approvals, including a pending Wastewater Change Petition. The project is located at WRP 4 in Thermal, California, ZIP 92274, and must comply with Title 22 of the California Code of Regulations for recycled water quality, as well as federal and state environmental laws including the Clean Water Act, CEQA, RCRA, and DOT regulations. Environmental evaluations have been completed under CEQA, assessing impacts on air quality, water quality, hazardous materials, biological resources, and transportation, with findings categorized as no impact, less than significant, or significant and unavoidable. All construction activities must adhere to stormwater pollution prevention plans developed by qualified practitioners, and hazardous waste packaging, labeling, and storage must meet RCRA and California Hazardous Waste Control Act requirements. The Coachella Valley Water District serves as the lead agency and contracting authority, with William Patterson as the primary point of contact for oversight and environmental compliance. No contract value, pricing structure, or procurement award criteria are specified, as the documentation reflects an environmental planning and permitting stage rather than a competitively awarded contract. Payments, invoicing, and accounting codes are not detailed, and no formal contract clauses, representations, or certifications from offerors are included. The project is classified as a forecast initiative with no assigned solicitation number, and submission of proposals is not part of the current process, which remains focused on regulatory review and public comment through September 2025.
