Memorandum
To: Board of Directors
From: Neil Kaufman
Date: February 25, 2004
Subject: Construction of the District Pipeline Replacement-2005 Project
1. Why this matter is before the board:
District Staff has prepared a set of Bid Documents for construction of the District Pipeline
Replacement-2005 Project.
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:
The purpose of this project is to continue the District's ongoing efforts to replace existing
pipelines in poor condition.
3. New information:
There are two major components to this project.
1) Replacement of about 4,500 of leaking pipelines in the Tahoe Donner subdivision.
Funds for this project were included in the Water Department's 2005 budget for this
project. The planned funding source is rate monies.
2) Replacement of about 1,600 feet of pipeline in Richards Boulevard. There is an existing
14" steel pipeline located on Richards Boulevard that was installed in 1973. This pipe is
currently functions at a pressure of 40-50 psi. With the construction of Richards Pump
Station the pressure in this pipeline would be increased to about 225 psi. When the
Richards Pump Station was first operated in December 2004 this pipeline experienced a
number of failures and it unable to function at this higher pressure. As a result,
replacement of this pipe is necessary.
This 1,600 foot segment of pipe is the "missing link" that is preventing the District from
converting the Donner Lake area off the Lake Intake to a groundwater supply. This pipe
on Richards Boulevard is scheduled to begin construction on May 2, 2005. Once this
pipe is completed the District will have fulfilled all of the requirements of the Department
of Health Services compliance order covering the Donner Lake area.
4. Recommendation:
I recommend that the Board:
1) Approve of the plans and specifications for the project.
2) Authorize staff to begin advertising for Bids with a Bid Opening Date of March 30,
2005.
