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.
