As the county's primary water wholesaler, the water district makes sure there is enough clean, safe water for homes and businesses. To finance this monumental task, the water district collects revenue, primarily from property taxes, well owners, agricultural water customers and water retailers, such as San Jose Water Company.
Most county residents do not pay a bill directly to the Santa Clara Valley Water District, instead they pay their local water retailers. The cost local residents pay the retailers, however, is affected by the cost to the district of supplying that water.
The water district’s major costs include operations, debt service, capital improvements to the treatment and delivery system, and water purchases from outside the county.
To avoid large charge increases in any year, the water district develops 10-year projections so that charges can be increased gradually when needed.
