Kent is a mid-sized city and the 6th-largest in Washington, home to roughly 126,952 residents. Kent's drinking water comes largely from the same regional sources that serve Washington: Cascade snowpack, Columbia River, Yakima River, and groundwater.
As elsewhere in Washington, the central challenge is drought. Snowpack-dependent supplies and the Yakima Basin's irrigation needs drive long-term planning despite a wet reputation.
Washington reuses an estimated 10% of its treated wastewater and maintains developing reuse programs; Kent tracks abnormally dry to moderate drought conditions on the U.S. Drought Monitor scale.

Drought
Much of the American West is in a multi-decade dry period that researchers describe as the most severe in over a millennium, reshaping how communities plan for water.
ExploreAgricultural Demand
Agriculture accounts for the majority of consumptive water use in the West, making farm efficiency and water markets central to any supply solution.
ExplorePotable Reuse
Advanced purification turns treated wastewater into water that meets or exceeds drinking-water standards — increasingly essential in water-stressed regions.
ExploreSnowpack Decline
Mountain snow is the West's largest reservoir. As warming shifts snow to rain and melts it earlier, the timing and reliability of water supply are unraveling.
