Welcome to Sun Valley General Improvement District

The District owns and maintains an estimated 100 miles of water mains, 120 miles of sewer mains, two sewer vaults, several pressure reducing vaults and pumping stations, and nine water storage water tanks. Since its inception, all service connections have been metered. In the early 1990s the District converted to an automated metering system.


On April 8, 2021 the District approved to increase the residential, commercial and bulk single use water consumption rate by 2.5% per year for each of the next three years to coincide with the planned similar increases by TMWA. These increases have been adopted and approved by the District Board of Trustees and will go into effect beginning June 1, 2021. For more information view the District’s Tariff for full details.
