Projects

Miragrand Well Project
Construction of a new groundwater production well to be housed within an approximate 750 square-foot building and associated discharge pipeline to connect the well to the Three Valleys Municipal Water District (TVMWD) Miramar Treatment Plant located at 1021 E. Miramar Avenue. The purpose of the project is for TVMWD to produce approximately 700 to 800 acre-feet per year (AFY) of groundwater for the purpose of increasing local water supplies and improving overall water supply reliability.

Regional Drought Contingency Plan
Although California experienced record-level storms in 2023, we must prepare for the next water shortage as drought conditions caused by hot, dry weather are estimated to continue into the future – now is the time to plan before severe drought impacts return.
To combat these issues, Three Valleys is embarking on the preparation of a Water Resources Master Plan and Drought Contingency Plan (WRMP and DCP) that will help to address regional water supply reliability challenges by identifying and prioritizing projects and actions to be included in a roadmap for enhancing the region’s water supply portfolio.
Estimated Planning Completion Date: December 2024
