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, on July 21, 2017 the District staff publicly advertised a Request for Bids for
the Cla-Val Hydraulic Control Valve Maintenance Parts and Materials. A public bid
opening was held on July 28, 2017, in which 3 bids were received. The table below
provides a breakdown of the bids received for the entire inventory of parts and
materials identified.

and
2) Authorize the General Manager to execute a purchase agreement with Western
Nevada Supply in the amount of $21,975 plus tax, plus a 10% contingency of $2,198,
