FROM: FINANCE
SUBJECT: OVERVIEW OF 1991 WATER STATUS
RECOMMENDATION:
Receive and file.
DISCUSSION:
With the onset of 1991 the State of California entered into its
fifth consecutive year of drought conditions. These conditions
prompted the Metropolitan Water District (MWD) to implement strict
mandatory water conservation guidelines. The following is a summary
of the actions undertaken during 1991 by The City of Tustin to meet
conservation guidelines set by MWD:
■ March 1 - MWD notified the City of Tustin that our
purchased water allotment would be reduced by 30% and a
penalty of $350 (in addition to the $263 cost of water) an
acre foot would be assessed, for water used over the
allotment. In addition a $99 credit would be given for each
acre foot used under the 1989-90 base year allotment. This
mandatory program went into effect February 1, 1991 which
caused the City to be assessed $7,643.60 in penalties.
■ March - 31% monthly conservation rate obtained.
■ April 1 - City of Tustin Emergency Ordinance 1063 public
hearing and first reading, implementing a 15% mandatory Water
Conservation Program. The program established a tiered rate
structure which penalizes those individuals that exceed the
"allowable water usage" and also set up a variance process.
■ April 15 - Mailed letters to all water customers to inform
them of the mandatory Water Conservation Program along with
their past consumption history.
■ April - 16% monthly conservation rate obtained.
■ May - 17% monthly conservation rate obtained.

■ June 22 - First billing mailed that contained penalties for
excessive usage. Prior to this day staff had approved over
1,000 requests for variances.
■ June - 17% monthly conservation rate obtained.
■ July - 31% monthly conservation rate obtained.
■ August 24 and 25 - Participated in the MWD/ Mc Donalds
Retrofit Kit Distribution Program. The City purchased 500
showerheads for customer replacement program.
■ August - 25% monthly conservation rate obtained.
■ September - 19% monthly conservation rate obtained.
■ October 1 - MWD notified the City that all incentive
credits have been eliminated and the penalty was increased to
$444 (in addition to the $263 cost of water) for each acre
foot used over the allotment.
■ October 21 - Due to the continued conservation rates
obtained, Council authorized staff to continue the summer
water allotments through the winter period.
■ October - 10% monthly conservation rate obtained.
■ November - Mailed out postcards to all 13,000 water
customers to congratulate them for maintaining conservation
goals and to inform them of higher allotment usage for winter
periods.
■ November - Did not meet conservation goal and exceeded
base year usage by 30.
■ December - MWD informed the City of a proposed purchased
water rate increase of $61 an acre foot (total cost of $324)
effective July 1, 1992.
■ December - 764 students in service area were educated on
the importance of water conservation through the MWD education
programs. The program will continue through January and City
staff will assist MWD.
■ December - Returned 300 of the shower heads due to lack of
program participation.
■ December - 19% monthly conservation rate obtained.

The overall annual conservation rate obtained was 15.5%. The
conservation efforts of the water service customers, coupled with
the added groundwater production provided by the Nitrate Removal
plant, allowed the City to receive credits in the amount of
$126,729 for 1991. Attachment I and II detail the conservation
efforts by month for the year. Additionally, Attachment III
graphically depicts water conservation target information. Staff
has reviewed and approved over 3,000 requests for variance, which
are approximately 23% of all water accounts.
The water supply outlook for 1992 still remains uncertain. At this
point, MWD will continue with all restrictions (attachment IV).
Staff will continue to monitor the water supply and will report any
changes or modifications that may be needed to update the City's
conservation effort.

IMPORTED WATER SUPPLY OUTLOOK FOR 1992
JANUARY 8, 1992
Early January rains in Southern California have raised the hopes of many that relief is at
hand from the drought. The fact is that, as of January 8th, the situation remains very
serious. The amounts of precipitation in the Sacramento River watershed were less
significant than the amounts in Southern California. The estimated shortage of
Metropolitan imported water for 1992 remains at about 35%, compared to the 30%
called for in Stage V of the Incremental Interruption and Conservation Plan. There is
only about a 30% chance that sufficient additional rainfall will occur to just meet 100%
of the needs of 1992, without supplying any relief in the critical carryover storage
situation.
Precipitation in the Sacramento River watershed to January 8, 1992 is about 60% of
normal -to -date. The precipitation season is about 40% passed. It is estimated that
about 90% of normal precipitation will be needed to meet the minimum 80% runoff
level. For the rest of the precipitation season, the amounts needed to meet the total
season 90% precipitation level would be 110% of normal. Even for the short, rainy
period from January 1 to January 8, precipitation was only 108% of normal for that
period. Oroville Reservoir, storage for the State Water Project, now contains about
30,000 acre-feet less than the 1.3 million acre-feet it held on December 1st.
The reservoirs on the Colorado River typically contain very large amounts of carry-over
storage, which is used to augment seasonal run-off, when necessary. On November 30,
1991, the reservoirs affecting the supply available for Metropolitan contained 68% of
their full capacity of 51 million acre-feet. The year 1991 yielded poor runoff on the
Colorado River. Storage had declined 2.3 million acre-feet since November 30, 1990.
From the Colorado River in 1992, Metropolitan has been authorized to divert a full
aqueduct (about 1.2 million acre-feet).
