SUMMARY: Director Brower has asked that issue of
California American Water’s (Cal-Am) unaccounted-for-water losses be presented
to the Board for discussion.
Unaccounted-for-water losses are defined as the difference between the
quantity of water recorded at production meters and the quantity of water
recorded at the users’ meters or estimated as reasonable use.
Unaccounted-for-water uses include unknown leakage, stolen water, unreported
fire department usage, unreported street sweeping, unrecorded construction
water, and customer meters that under register the amount of water delivered. The District’s unaccounted-for-water use
standard is seven percent, calculated as the amount of unaccounted-for-water
use in acre-feet divided by the total amount of water produced in acre-feet. In Water Year (WY) 2009, Cal-Am reported
total well production to serve customers in its main system of 13,099 acre-feet
and total “point of delivery” of 11,519 acre-feet (Exhibit 20-A). Accordingly, Cal-Am’s
unaccounted-for-water uses in its main system in WY 2009 were 1,580 acre-feet
or 12.1 percent of total production.
As adopted, State
Water Resources Control Board (SWRCB) Order WR 2009-0060 requires Cal-Am to
reduce its system losses by five percent, i.e., from 12 percent to seven
percent, in WY 2010. When applied to
Cal-Am’s new base diversion from
RECOMMENDATION: The Board should receive the information presented at the November 16 Board meeting concerning Cal-Am’s current unaccounted-for-water use and provide direction to staff regarding further actions.
