Document Description
The Coachella Valley Water District (CVWD) proposes to construct a replacement well (Well T-6A) and destroy an existing well (Well T-6) located at the Dos Palmas Reserve. The Dos Palmas Reserve is a federally designated oasis managed by the Bureau of Land Management (BLM). Well T-6A and land is owned by San Diego County Water Authority. Project construction is anticipated to begin in or around December 2025 and last approximately 30 calendar days.
Construction of Well T-6A will consist of mobilization, drilling an exploration borehole to 120 feet below ground surface, performing a geophysical survey, placing a 50 foot conductor casing and sanitary seal, reaming the borehole, furnish and install 8-inch diameter PVC well casing and screen, furnish and install 20 feet of 8-inch diameter low carbon steel for the upper portion of the well, placing a filter pack around the casing and screen, installing a bentonite transition and concrete annular seal and developing the well, and installing a well head and concrete pad. All drilling fluids, drill cutting, and development water on site will be contained and will not reach the surrounding habitat during construction.
Destruction of Well T-6 will include obtaining a well destruction permit, mobilization to the site including site preparation to reach the well, destroying the well per county standards. Upon destruction of Well T-6, a Well Completion Report will be prepared and submitted to the California Department of Water Resources and Riverside County.
