Drinking Water

MSWD is proud to serve some of the best-tasting drinking water in the world, drawn from the Mission Creek Subbasin aquifer, and is committed to responsible stewardship of that water. Additionally, the District complies with regulations that require the annual publication of a Consumer Confidence Report on water quality. It provides source water analysis, performance on water quality standards and other information regarding the quality of your water supply. The 2007 Water Quality Report, sent to each customer by July 2007, is also available for download here.

Hot Water

The many spa resorts in Desert Hot Springs draw thier natural hot mineral waters from their own wells in the Desert Hot Springs Subbasin aquifer. The water in this aquifer seeps down through fissures deep into the earth, where it is heated and rises back up through those fissures as superheated steam, warming the water held in the hot water aquifer. MSWD is often asked for maps of the hot water zone and so we have supplied them here. Please note that these maps are 20 to 30 years old, so spas listed on them may no longer exist and exact boundaries and temperature readings may no longer be accurate. At this time, MSWD does not draw any water from the hot water aquifer and these maps are provided for information requests only.
