Department of Watershed Management Efforts to Reduce Water Loss
Released: April 2017 Download the Full Report here Download the Highlights Page here We undertook this audit of the Department of Watershed Management’s efforts to reduce water loss to determine whether it has complied with state-mandated annual water loss initiatives and to evaluate the efforts compared with industry benchmarks. |
|
We found:
- Water loss from the city system averaged 9.9 billion gallons per year between 2013 and 2015
- Real losses—physical losses from the distribution system—increased 17% from 2013 to 2015
- Apparent loss—water that is unaccounted for due to error or unauthorized consumption—decreased 30% from 2013 to 2015
- The department has implemented most of its consultant's recommendations to reduce apparent losses and to improve data validity
- Aging infrastructure is the primary driver of real loss
- An active leak control program, as recommended by the department's consultant, could reduce real losses
