Water Services




The Mountain House Community Services District (MHCSD) uses the latest technology to treat and deliver fresh, clean water for its residents. The MHCSD has taken extra measures to ensure water conservation. For example, irrigation computers will detect rainfall and will water landscaping accordingly in order to conserve water.

Mountain House’s water comes from the Clifton Court Forebay along the Delta and is delivered by the Byron-Bethany Irrigation District (BBID). The water is then stored in the Mountain House water tank where it is treated and pumped into the community for distribution.

There are a variety of regulations that pertain to water conservation. A few are listed below. For the full ordinance click here.
