Conserving Water

As we enter our 4th year of the drought many customers are concerned about our water supply and what they can do to help. The Sun Valley General Improvement District buys water wholesale from the Truckee Meadows Water Association (TWMA) who owns and operates the only water treatment plants in the Truckee Meadows. TMWA also operates several groundwater wells in the region to offset the surface water use from the Truckee River. TMWA is assuring us that they are prepared to meet the demands of all water users by utilizing its drought storage located in Donner and Independence Lakes. TWMA is also asking that all its customers including the Sun Valley District to reduce water use by 10%. For water saving tips to meet this goal, please visit our Customer Information/Conservation tab.
