water; and
WHEREAS, the District is an urban supplier of water providing water to over 3,000 customers; and
WHEREAS, the Plan is periodically reviewed at least once every five years, and the Truckee Donner
Public Utility District last reviewed and made amendments or changes to its plan on June 1, 2011; and
WHEREAS, the District has prepared and circulated for public review a draft Revised Urban Water
Management Plan 2010, Section 7, and a properly noticed public hearing regarding said Plan was held
by the Truckee Donner Public Utility District on September 10, 2014; and
• WHEREAS, provided that the Plan is adopted on September 10, 2014 after the public review and
hearing, it will take effect on October 10, 2014 and be filed with the California Department of Water
Resources within thirty days of adoption; and
NOW, THEREFORE, BE IT RESOLVED by the Board of Directors of the Truckee Donner Public Utility
District as follows:
1. That the above recitations are true and correct.

The effective management of water supply shortages is an important responsibility of

natural disasters, or other adverse conditions. Therefore, it is necessary to have an
1110 effective management program to mitigate water supply shortages.

Section 7—Water Shortage Contingency Plan
As described in Section 5, the District is using groundwater as its sole source of supply. •
The Martis Valley Groundwater Basin has a storage volume of about 484,000 acre-feet
(AF) and is able support annual withdrawals of at least 24,000 acre-feet per year (AFY)
Based upon current withdrawals of about 7,175 AFY, there is over 65 years worth of water
supply available even if there was zero recharge of the groundwater basin. A three year
minimum supply of 24,000 AFY has been assumed.
The most likely cause of a water supply shortage would be th �I, ailure of a major water
supply facility such as a well, pump station or transmission pi• ='tn. Such an occurrence
could be caused by a number of factors including earth 3, fire or major equipment
failure. As a result, water supply shortages are expecte ,1b-�,:I` ewhat short in duration

(days or possibly weeks), but may occur without any we�fg. istrict s water system
consists of five major components: control valve '�t"°� ipns, groui er wells, pipelines,
pump stations and storage tanks. In May 200 , District comps '"' a Vulnerability
Assessment that identified the number of c , shiers that would be impacted by major
failure of a given facility. In conjunction with Vulnerab l ty Assessor ,`jithe District

development oi" ,,41/ i�, i s new metered rate structure. This new rate structure became
effective in Januaf 010. One of the major objectives in developing this new rate
structure was to cloely match the District's variable revenue stream with its variable
expenses and to match its fixed revenue stream with its fixed expenses. Currently, about
85 percent of the Water Department's expenses are fixed and do not vary with the amount
of water sold to customers. The remaining 15 percent of expenses is for the costs of
pumping and treatment and will vary with customer usage.
In the event that a Stage 45 conservation requirement (50 percent reduction in water
usage) was imposed for a significant length of time (a number of months), the District
II
Page 7-5

Section 7—Water Shortage Contingency Plan
would expect to see a revenue reduction of about 7.5 percent. However, there should be •
a corresponding reduction in expenses associated with less water being treated and
pumped to customers. Any remaining differences between revenue and expenses would
likely be covered through the use of reserves. The District would then have to evaluate
its overall financial situation during the next annual budget cycle. At that time, the District
would review whether rate adjustments were necessary to ensure the financial stability of
the Water Department.
The District does not expect any significant impact on expen Lures associated with a
drought-related water shortage. In the event of a major ,i {�i,l 1'supply facility failure,
unforeseen expenses can be expected. District staff and/9 r,, „ tside contractors may be
required to work overtime and weekends to repair the da , ' e ill.cility, install a temporary
facility or adjust system operations in order to m'a ain r service to District
customers. Similar to a drought-related water sho„' 11! e, it is expe6 that the immediate
