Memorandum
To: Board of Directors
From: Peter Holzmeister
Date: May 13, 2005
Subject: Workshop on Urban Water Management Plan Section on Water
Sortage Contingency Plan
Why this matter is before the board: At a recent meeting, Neil Kaufman
presented a draft Urban Water Management Plan to the board. He stated that
there is one section in the document in particular that deserves a special review
by the board and suggested that it come back as a workshop item. That is the
purpose of this item.
History: As already stated, Neil Kaufman has prepared a draft Urban Water
Management Plan as required by state law. He recently made a brief
presentation to the board on the draft document and specifically directed our
attention to Section 7 entitled Water Shortage Contingency Plan and to the
proposed ordinance found in Appendix C. Copies of Section 7 and the proposed
ordinance are attached for your convenience.
New Information: There is no new information. We simply want at this time to
discuss this Section with the directors in a workshop setting.
Recommendation: This is a workshop. No action required.

SECTION 7
WATER SHORTAGE CONTINGENCY PLAN
Law
F 10632. The plan shall provide an urban water shortage contingency analysis which includes each of the
following elements which are within the authority of the urban water supplier:
(a) Stages of action to be undertaken by the urban water supplier in response to water supply
shortages, including up to a 50 percent reduction in water supply, and an outline of specific water
supply conditions which are applicable to each stage.
(b) An estimate of the minimum water supply available during each of the next three water years
based on the driest three year historic sequence for the agency's water supply.
(c) Actions to be undertaken by the urban water supplier to prepare for, and implement during, a
catastrophic interruption of water supplies including, but not limited to, a regional power outage,
an earthquake,or other disaster.
(d) Additional, mandatory prohibitions against specific water use practices during water shortages,
including,but not limited to,prohibiting the use of potable water for street cleaning.
(e) Consumption reduction methods in the most restrictive stages. Each urban water supplier may use
any type of consumption reduction methods in its water shortage contingency analysis that would
reduce water use, are appropriate for its area, and have the ability to achieve a water use reduction
consistent with up to a 50 percent reduction in water supply.
(f) Penalties or charges for excessive use, where applicable.
(g) An analysis of the impacts of each of the actions and conditions described in subdivisions (a) to
(f), inclusive, on the revenues and expenditures of the urban water supplier, and proposed
measures to overcome those impacts, such as the development of reserves and rate adjustments.
(h) A draft water shortage contingency resolution or ordinance.
(i) A mechanism for determining actual reductions in water use pursuant to the urban water shortage
contingency analysis.
The effective management of water supply shortages is an important responsibility of water
agencies. Shortages may be caused by failures of major water supply facilities, natural disasters,
or other adverse conditions. Therefore, it is necessary to have an effective management program
to mitigate water supply shortages.
As described in Section 5, by the Summer of 2005, the District should be using groundwater as
its sole source of supply. The Martis Valley Groundwater Basin has a volume of about 484,000
acre-feet (AF). Based upon current withdrawals, there is over 20 years worth of water supply
available even if there was zero recharge of the groundwater basin. Consequently, the most
likely cause of a water supply shortage would be the failure of a major water supply facility such
as a well, pump station or transmission pipeline. As a result, water supply shortages are
expected to be somewhat short in duration (days or possibly weeks), but may occur without any
warning.
The District's water system consists of five major components: control valve stations,
,Y
groundwater wells, pipelines, pump stations and storage tanks. In May 2004, the District
Page 7-1
- Section 7-Water Shortage Contingency Plan
completed a Vulnerability Assessment that identified that number of customers that would be
impacted by major failure of a given facility. In conjunction with the Vulnerability Assessment,
the District has been updating its Emergency Response Plan which identifies actions to be taken
in the event of a major failure of a given facility.
WATER CONSERVATION PROGRAM
Depending upon the type of failure, the location and the number of customers affected, it would
be necessary for the District to implement some form of water conservation— either voluntary or
' mandatory. Table 7-1 identifies the various stages of water conservation measures that would be
implemented.
Table 7-1. Water Conservation Stages
Stage Water Conservation Requirement Compliance Level
1 10%Reduction in Usage Voluntary
2 30%Reduction in Usage Mandatory
3 50%Reduction in Usage Mandatory
Stage T Water Conservation
Stage I would apply during periods requiring a reduction of 10 percent in water usage. This
would be achieved through voluntary measures. All new water connections would be prohibited
within the area affected. The withdrawal of water for construction purposes would also be
prohibited.
Stage 2 Water Conservation
Stage 2 would apply during periods requiring a reduction of 30 percent in water usage. All
outdoor water usage would be prohibited. Penalties and fines would be imposed for violations of
the water conservation program.
Stage 3 Water Conservation
Stage 3 would apply during periods requiring a reduction of 50 percent in water usage. If
necessary, mandatory rationing and temporary outages would be implemented by the District.
Penalties and fines would be imposed for violations of the water conservation program.
PROPOSED WATER CONSERVATION ORDINANCE
#' Attached in Appendix C is an ordinance adopting a water conservation program that was passed
by the District's Board of Directors as part of development of this Urban Water Management
Plan. This ordinance outlines three stages of water alerts that describe different required
conservation savings. These conservation savings range from voluntary compliance with
reasonable conservation efforts in Stage 1 to a mandatory 50 percent reduction in Stage 3.
This Ordinance also authorizes the General Manager of the District to implement these measures
immediately upon occurrence of an event requiring such conservation measures. A public
meeting of the Board of Directors would then be scheduled as soon a possible to inform the
Board and the public of the emergency, the actions taken by the District and the expected
duration until the problem can be corrected.
