With a long history of migration based upon season and climate, we appreciate the importance of water to all life. To this day, all tribal operations and enterprises prioritize water conservation and water quality.

  • To treat potable water at Cache Creek Casino Resort (CCCR), the Tribe employs a state-of-the-art Electrodialysis Reversal system, which is among the most advanced treatment technologies employed in the industry and generates clean water while reducing salts.
  • CCCR wastewater is treated to a tertiary level using a membrane bioreactor technology, which generates water that is safe for human contact. Over 80 million gallons are recycled annually to flush toilets at CCCR and to irrigate Golf Club turf, creating a valuable resource from what would otherwise be a waste product.
  • To protect Cache Creek and its riparian habitat, the Tribe has partnered with the Cache Creek Conservancy, local students, and the U.S. Fish & Wildlife Services to eradicate invasive species such as tamarisk and arundo, which can adversely affect stream flow and natural habitat, and to replace them with native plants.
  • The Tribe has completed two restoration and bank stabilization projecta along Cache Creek in order to prevent further erosion, and create new riparian habitat for fish and wildlife.
  • To reduce water use on its lands, the Tribe uses native landscaping and drip irrigation. On crops that require flood irrigation, the runoff is captured and pumped back to the fields.
  • To reduce water onsumption on its properties, many buildings have been retrofit with low-flow fixtures, and new buildings are designed with water conservation measures. 
  • To improve water quality, stormwater from the CCCR property is channeled through oil-water separators before making its way to a detention basin located on agricultural land across the highway, where it can then be repurposed for farm irrigation. 
  • To reduce waste and conserve water, the olive juice and wash-water generated at the Tribe’s Séka Hills Olive Mill is collected and used to irrigate farmland. 
  • The Tribal Water Well Ordinance establishes a permitting process that protects groundwater quality by prescribing best practices for all well work conducted on tribal lands.
  • All tribal wells are either properly maintained and utilized or properly abandoned, so that they do not become potential conduits for groundwater contamination.
  • The Tribe serves on the board of the Yolo Subbasin Groundwater Agency, which is responsible for ensuring the sustainable use of groundwater throughout Yolo County.
