To: Board of Directors
From: Brian Wright
Date: July 19, 2017
Subject: Consideration for the Approval of the Procurement with Cla-Val
Hydraulic Control Valve Replacement and Repair Inventory
1. WHY THIS MATTER IS BEFORE THE BOARD
District Code requires that all procurements exceeding $15,000 in total cost be
approved by the Board.
2. HISTORY
The TDPUD water utility distribution system includes more than 200 miles of pipeline,
13 wells, and 32 pump stations delivering safe and reliable potable water to more than
12,000 service connections, across 46 pressure zones. In order to maintain reliable
water pressure across each of these zones, the utility distribution system is equipped
with pressure regulating valves (PRV) and pump control valves (PCV). These valves
are hydraulically actuated pressure and flow control valves strategically placed at
critical points in the distribution system to maintain manageable pressures across the
wide range of elevations and within pump stations to manage rapidly changing
pressure and flow during pump start-up and shut -down. The majority of the District's
inventory of more than 115 distribution system PRVs and pump control PCVs are
manufactured by Cla-Val, with original installation dates going back to the late 1970's.
In addition to periodic adjustments, these control valves require regularly scheduled
maintenance which may include the repair or replacement of the various control
assemblies. In most circumstances, the individual control components can be
cleaned and repaired with only the replacement of minor components. However, in
some instances, the entire control assemblies or valve bodies are found to have
reached an age or level of deterioration that requires complete replacement. The
District's water operations staff conduct an annual control valve inspection and
maintenance program to evaluate valve conditions and identify the necessary
inventory of replacement parts and materials.
3. NEW INFORMATION
The District's water operations staff has created an inventory of replacement parts and
materials for the water system control valves to be serviced in the 2017 control valve
maintenance program. In an effort to facilitate a fair and competitive procurement
process, District staff provided a parts and materials inventory to the manufacturer
and two regional distributors with a a request for price quote. The table below
provides a breakdown of the price quotes received for the entire inventory of parts and
matenais iaentitiea.

Costa Mesa, CA
$ 29,710,00
Ferguson Waterworks

Staff has reviewed the price quotes provided by the individual vendors, and after
applying the District's 5% local preference credit, has determined Ferguson
Waterworks as the vendor providing the lowest competitive price.
4. FISCAL IMPACT
Sufficient funds exist within the Water General Fund for this procurement.
5. RECOMMENDATION
Staff recomendations are to:
1) Approve the procurement of control valve maintenance parts and materials;
and
2) Authorize the General Manager to execute a
Ferguson Waterworks in the amount of $21,585 plus tax,
$2,159, for an amount not to exceed $23,744 plus tax.
