DONNER
Public Utility District
Memorandum
To: Board of Directors
From: Jessica Wilson
Date: April 18, 2007
Subject: Construction of the Storage Tank Rehabilitation-2007 Project
1. Why this matter is before the board:
Approval from the Board of Directors is necessary for two issues related to the Storage Tank
Rehabilitation—2007 project;
1) Approval of the specifications for the project
2) Authorization to advertise for Bids
2. History:
The District's system has 31 steel storage tanks that require periodic cleaning and maintenance. The
tanks are protected from rust and corrosion by their interior and exterior coatings, which typically have a
life span of 20 to 25 years. Many of the tanks were constructed in the early 1970s and their coatings
have passed their serviceable life span. To address this issue, the Water Department has begun an in-
house program to overcoat and patch the exterior coatings of the tanks. The District does not have the
equipment for nor personnel experienced in recoating the interior of the tanks. Therefore, the Water
Department proposes to employ an experienced coatings contractor to recoat one or two tanks a year,
beginning with the oldest and/or most deteriorated tanks.
3. New information:
Sierra Meadows Tank and Donner Trails Tank No. 1 are the highest priority tanks to recoat at this time,
based on their condition, age, and significance to the system. The Water Department's 2007 budget
allocated $100,000 for storage tank maintenance, which should be the approximate cost to recoat the
two tanks.
The specifications are complete and ready to be advertised. The current project schedule is given
below:
April 18, 2007—Board Authorization to Begin Advertising for Bids and Receive Bids
May 16, 2007—Bid Opening
May 23, 2007—Award of Contract
August 6, 2007—Begin Construction
4. Recommendation:
I recommend that the Board:
1) Approve the specifications for the Storage Tank Rehabilitation-2007 project.
2) Authorize staff to begin advertising for Bids and receive Bids with a Bid Opening Date of
May 16, 2007.
