The Stockton East Water District (SEWD) manages groundwater and provides surface water for both agricultural and urban uses.

By providing surface water for agricultural irrigation, the District supports San Joaquin County’s agricultural industry, which is the area’s leading economic activity.

Through efforts to provide treated surface water for urban delivery to the 325,000 residents within the City of Stockton, seawater intrusion has ceased and declining groundwater levels under the city have been reversed.
