Memorandum
To: Board of Directors
From: Neil Kaufman
Date: January 3, 2008
Subject: Construction of the District Pipeline Replacement—2008 Projects
1. WHY THIS MATTER IS BEFORE THE BOARD
The District is proposing construction of the 2008 Pipeline Replacement Project. The Water
Department has prepared Bid Documents for construction of the following contracts.
• District Pipeline Replacement—2008—Contract A
• District Pipeline Replacement—2008— Contract B
• District Pipeline Replacement—2008—Contract C
Approval from the Board of Directors is necessary for two issues related to this project;
1) Approval of the plans and specifications for the project
2) Authorization to advertise for Bids
2. HISTORY
In 2005 and 2006, the Water Department made some presentations regarding the condition of
existing water pipelines and the need to pursue a pipeline replacement program. This pipeline
replacement program is part of the District's Objective No. 1 — Provide an adequate, reliable, and
high quality water supply and distribution system to meet current and future needs and
Objective No. 5 — Manage the District in an environmentally sound manner. Specific goals under
these objectives are Goal No. 1.4 — Provide effective and efficient maintenance and replacement
programs, Goal No. 5.4 — The District will conduct its business in an environmentally lawful
manner and Goal No. 5.6 — The District will seek to minimize any negative impact of its
operations on the environment.
The District subsequently issued a COP in 2006 and dedicated a portion of those funds for the
pipeline replacement program. Pipeline construction projects have been undertaken during 2006 and
2007 as part of this program. At the September 19, 2007 Board Meeting, Ed Taylor made a
presentation regarding planned Water Department Capital Expenditures for 2008. This presentation
included a discussion of the planned pipeline replacement projects.
The planned 2008 pipeline construction covers about 17,500 feet of pipeline. These pipeline
alignments are shown on Figure 1. The overall replacement program for 2008 has been broken into
three separate contracts for bidding purposes. Contract A covers work in Tahoe Donner. Contract B
covers work in Sierra Meadows and Ponderosa Palisades area. Contract C covers work in the
Glenshire area.

3. NEW INFORMATION
The Bid Documents for the pipeline replacement contracts are essentially complete and ready for
advertising. The current project schedule is given below:
October 3, 2007—Board Approval of Inland Ecosystems Contract
December 5, 2007—Board Approval of CEQA Initial Study
December 19, 2007—Public Hearing on CEQA Initial Study
January 9, 2008—Adoption of Final CEQA Document
January 9, 2008—Board Authorization to Begin Advertising for Bids
February 20, 2008—Bid Opening
March 5, 2008—Award of Contract
May 1, 2008—Begin Construction
The Water Department currently has about 12,400 customers. Of that total, about 650 are equipped
with meters that are read periodically. Therefore, the Water Department does not have proper tools to
track how much water is lost due to leaking and failing pipelines. However, the Water Department
does track total water supply production in a daily basis. After two years of projects in the current
pipeline replacement program, the District is starting to realize a reduction in the amount of water lost
due to leakage.
The attached graph shows total well production for the past five years. Attention should be paid to the
brown line showing well production for the year 2007. As the graph shows, total well production in
October and November 2007 is lower than that in January-March 2007 with a reduction of about
600,000 gallons per day. This compares to the years of 2003-2006 where the January-March and
October-November values are essentially the same.
4. SOURCE OF FUNDING
The majority of funding for the construction will be the COP issued in 2006. There is some pipeline
upsizing involved in the project so there will also be a contribution from Facility Fees. A more detailed
breakdown of proposed funding sources will be presented along with the Bid Opening results
5. RECOMMENDATION:
I recommend that the Board:
1) Approve of the plans and specifications for the following projects:
• District Pipeline Replacement—2008—Contract A,
• District Pipeline Replacement—2008—Contract B
• District Pipeline Replacement—2008—Contract C
2) Authorize staff to b gin advertising for Bids with a Bid Opening Date of February 20,
