The Rancho California Water District has contracted for a decision-making tool regarding operational and groundwater management decisions for the Temecula Valley Groundwater Basin.The RCWD board voted 7-0 on December 10 to approve a $185,000 contract with EKI Environment & Water, Inc., which is headquartered in Daly City. EKI completed a previous assessment phase, so a sole-source contract rather than a bid process was warranted.The initial agreement with EKI was approved by the RCWD board in April 2024. The project was structured into two phases, with Phase 1 being the development of a prototype decision-making tool and Phase 2 being the completion of a fully functional application. The decision-making tool allows RCWD staff to interact directly with the groundwater flow model
