G. Distribution System Loss
IRWD’s system distribution loss program began in the 1980’s. It has evolved into a robust, well- recognized program that is effective at maintaining very low levels of system loss. IRWD’s average real loss since 2020 is lower than its standard of 20 gallons per connection per day. The program includes active leak detection, regular meter testing and replacement. IRWD staff respond promptly and repair water leaks in a timely manner with minimal impact to customers. Generally, leaks are stopped within hours of being located or reported. The results of IRWD’s water loss audits, are reported in Section 4 and copies of the audits from FY 20-21 to FY 24-25 can be found at https://wuedata.water.ca.gov/awwa_plans.
