RESOLUTION ESTABLISHING THE SELF -
CERTIFIED WATER CONSERVATION
STANDARD FOR THE CITY OF BAKERSFIELD'S
DOMESTIC WATER SYSTEM.
WHEREAS, on May 5, 2015, the State Water Resources Control Board (State
Water Board) adopted Board Resolution No. 2015 -0032 and an Emergency
Regulation to address specific provisions of Governor Brown's Executive Order
that included a mandatory 25% statewide reduction in potable urban water use
between June 2015 and February 2016; and
WHEREAS, to implement the Executive Order, the Emergency Regulation
placed each urban water supplier in a conservation tier, ranging between 8%
and 36 %, and City's Domestic Water System was given a conservation standard
of 36 %; and
WHEREAS, on May 9, 2016, Governor Brown issued another Executive
Order calling on the State Water Board to adjust emergency water conservation
regulations through the end of January 2017 in recognition of differing water
supply conditions across the state; and
WHEREAS, on May 18th, the State Water Board adopted a revised
statewide water conservation approach requiring locally developed
conservation standards based upon each agency's specific circumstances;
and
WHEREAS, urban water suppliers self- certify the level of available water
supplies they have by assuming three additional dry years, and the level of
conservation necessary to assure adequate supply over that time; and
WHEREAS, suppliers that would face a shortage after a third dry year are
required to comply with a conservation standard equal to the amount of that
shortage; and
WHEREAS, the calculation worksheet attached as Exhibit "A" to this
Resolution establishes that the City's Domestic Water System will have a 9%
conservation standard.

Notes on Step 2'.
1. It is assumed based on current hydrology for 2016. City will have 37,200 of of water in storage on Sept. 30, 2016.
2. On Sept. 30, 2012 there were approximately 19,700 of of water in storage.
3. It is assumed that there will be a 10% evaporation rate on the additional 17,500 of of water stored in Isabella over the
three year period (from Sept. 30, 2016 until Sept. 30, 2019)
4. It is assumed that in WY 18 -19 an additional 3,500 of will need to be withdrawn from storage to supplement treated
surface water supplies to the City of Bakersfield Domestic Water system via either the NW treatment plant or the NW Feeder.
Stag 3: Calculate Conservation Standard
Total Potable Water Demand - From Step 1 42,779 of
Total Potable Water Supply in Year 3 - From Step 2 39,000 of
Supply Shortfall in Year 3 (negative amount indicates a surplus) 3,779 of
Conservation Standard with Self- Certification of Supply Reliability
(Shortfall in Year 3) /(Total Potable Water Demand) 9%
