Fiscal Year 2020-2021 Non-Potable Water Connections Project
Document Type
MND - Mitigated Negative Declaration
Document Description
Initial Study & Mitigated Negative Declaration, and Notice of Intent to Adopt The project consists of the construction and operation of approximately 12 miles of non-potable water (NPW) pipeline segments and connections to provide irrigation water for seven local golf courses, one community church, and one sports and entertainment venue. These end users currently use on-site pumped groundwater or CVWD-supplied potable water for irrigation; there are no connections to canal water at this time. Under the proposed project, those water sources would shift to Blended Recycled Water provided from CVWD’s existing Water Reclamation Plant No. 10 (WRP10) facility, located at 43000 Cook Street in Palm Desert. WRP10 is equipped with a tertiary treatment design capacity of 15 million gallons per day (mgd). During the winter months, when current demand for recycled water is less than the available supply, a portion of the recycled water (tertiary water) is disposed through on-site percolation/evaporation ponds, which would be eliminated as more NPW users are connected to the NPW distribution system. The NPW pipeline would be installed in 200-foot-long segments, to limit project construction activities and associated disturbance to surrounding land uses. The project corridor is not included on any lists of hazardous materials sites compiled pursuant to Government Code Section 65962.5.
