2023 Water Use Efficiency

King County Water District No. 20 adopted the Saving Water Partnership Regional Conservation and Water Use Efficiency Goal is to Keep the total average annual retail water used by Saving Water Partnership members under 110 million gallon per day through 2028 regardless of forecasted population growth, this is achieved through reducing per capita use.

Water District No. 20 is one of a group of 19 total utilities that purchase wholesale water from Seattle Public Utilities and is part of the Saving Water Partnership Regional Water Conservation Program administered by Seattle Public Utilities. Water District No. 20 has set a distribution system leakage threshold of less than 10% for annual water loss. The goal is achieved through the annual water main leak detection program and meter replacement programs. Ratepayers are notified if meter readings indicate excessive usage or possible leaks detected through meter readings and/or the leak detection program. The 3-year average for the District is 6.6% System Leakage.
