Water Department Overview

The Morongo Band of Mission Indians Water Department under the direction the of Reservation Services Administrator’s office has the responsibility to provide a safe, reliable, and potable water supply to the reservation residents and commercial Enterprises. This department also maintains, operates, and provides non-potable water to residents where it is available within the residential areas.  The Tribe under the direction of the US Environmental Protection Agency conforms to the Safe Drinking Water Act and all regulatory rules. Also, our departments oversees the operations staff at the Tribal Wastewater reclamation facility and the domestic water system located at Tukwet Canyon Golf Club in Beaumont. A water conservation plan was developed and initiated in 2007 to help maintain and ensure that our most precious natural resource is protected for future generations.  


The Morongo Water Department is one of several departments serving the reservation area and Enterprise facilities. The department has 5 full time water system operators, 1 field supervisor, and the department manager, all of which are State Certified operators. The water system is controlled and operated utilizing the most advanced SCADA (Supervisory Control and Data Acquisition) system allowing operators to view and operate the system from any location in real time. Our water supply consists of groundwater production wells utilizing high efficient pumps and motors while maximizing efficient pumping rates to off-set high peak electrical demand time periods.

This mode of operation will save the Tribe $100-$150,000 each year in reduced energy costs savings. The Tribal water infrastructure consists of over 35 miles of potable water mains, 6 production wells, 5 disinfection stations, 15 pressure reducing stations, and 4 storage reservoirs.

Water Conservation & Resources

 The Morongo Band of Mission Indians recognizes the need for water conservation. This vital natural resource is the key to our future and has become an integral planning and operational component. Our department and the tribal Environmental Protection Department initiated a water conservation plan in 2007/08 to promote and educate Tribal residents and employee’s the value to conserve through mailers, information booths, conservation kits and technical advice. Normal daily usage (60-70%) occurs outside the home with only a fraction of usage occurring inside. As part of our plan we recommend California native plants (www.cnps.org), drip irrigation, and smart timers.

Water Quality

The Water Department has a primary responsibility to assure that the water that arrives at your tap meets or exceeds current water quality standards set forth by the Environmental Protection Agency. We sample over 100 constituents each year utilizing a State of California Certified Laboratory located in Riverside, CA.

Specifications & Standards

The Morongo Band of Mission Indians Water Department updated its construction specifications and standards for the construction of water facilities and conveyance systems in 2008, 2010 and a new revision in early 2016. These standards are developed to insure water infrastructure projects are built to current industry standards.
