HONORABLE CHAIRPERSON AND MEMBERS OF THE AZUSA UTILITY
BOARD
MANNY ROBLEDO, DIRECTOR OF UTILITIES��

SUBJECT: ANNUAL ADJUSTMENT OF REPLACEMENT WATER COST
ADJUSTMENT FACTOR
BACKGROUND:
The Replacement Water Cost Adjustment Factor (RWCAF) water rate schedule authorizes the
recovery of replacement water costs incurred by Azusa Light & Water pursuant to the delivery of
potable water to its customers from the Main San Gabriel Valley Water Basin. Effective July 1,
2019, the Replacement Water Cost Adjustment Factor (RWCAF) will be decreased from
$0.5467 to $0.5318 per hundred cubic feet of water (CCF). The RWCAF is based on actual
replacement water charges and assessments paid to the Main San Gabriel Basin Watermaster
(Watermaster) and the San Gabriel Valley Municipal Water District (SGVMWD) and a
projection of such charges through June 30, 2020. The RWCAF requires an annual calculation to
be performed and the Director of Utilities to inform the Utility Board of any adjustments.
RECOMMENDATION:
Staff recommends the Utility Board take the following action:
1)Receive and file this information report.
ANALYSIS:
ALW is part of an adjudicated basin under the administration of a court appointed Watermaster.
The rules of the adjudication give the Watermaster the authority to assess each acre foot of water
produced in the basin a Resource Development Assessment (RDA) for the purpose of purchasing
supplemental water. On May 1, 2019, the Watermaster Board approved a change in the RDA
from $105 per acre foot in the current fiscal year to $140 per acre foot in FY 2019-20 for all
water agencies in the Basin. The RDA of $140 per acre foot will be included in the RWCAF
formula effective July 1, 2019 and will impact ALW assessments by an estimated $3,048,717.

Annual Update of RWCAF

SGVMWD is responsible for importing and transmitting state water allocated to its members –
Azusa, Monterey Park, Alhambra, and Sierra Madre. State water imported by the district satisfies
about 40% of ALW’s demand. The March 2016 Water Rate Study performed for ALW by NBS,
established a baseline Water Replacement cost for Replacement Water of $795,500. Based on
the district rate of $200 per acre foot for FY 2019-20, this amounts to a baseline delivered water
volume of 3,978 AF. Based on SGVMWD’s rate for water delivered by Watermaster, ALW’s
cost to replace water pumped from the Basin is estimated to be $732,800 for FY 2019-20.
By this memorandum, Staff is providing notice to the Utility Board, as required by the Water
Rate Schedule, that the RWCAF was re-calculated and the new rate will be adjusted to $0.5318
for FY 2019-20 from the rate of $0.5467 set previously in January 2019. The RWCAF will be
decreased to $0.5318 effective July 1, 2019 and will be applied to all water bills beginning the
first billing cycle of the new fiscal year.
Accordingly, ALW’s lower RWCAF will provide estimated total Replacement Water cost of
$3,781,517 ($1,884,975 for City of Azusa production and $1,896,542 for Azusa Valley Water
Company production). Calculations were based on FY 2019-20 projected water sales of
7,110,560 CCF.
FISCAL IMPACT:
The RWCAF is design to offset the costs of water supply against forecasted sales; therefore, the
pass-through transaction will not have any anticipated fiscal impact.
