How it is Calculated

Under the City’s water rights, Azusa is allowed to pump a certain amount of water from the Main San Gabriel Basin. When the customers of Azusa use more than that amount of water rights, Azusa Light & Water must purchase additional water from Main San Gabriel Basin Watermaster.

The cost of this additional water is passed along to customers as the Replacement Water Cost Adjustment Factor, or R.W.C.A.F. This is determined once a year and the R.W.C.A.F. may be adjusted up or down according to a formula.
