Subject: Discussion Regarding Donner View Hydro Pneumatic Pump Station
Rebuild
1. WHY THIS MATTER IS BEFORE THE BOARD
The Water Department proposes to replace the existing Donner View Hydro
Pneumatic Pump Station system. The new building and pumping system will be
located at the same site. The work would be scheduled during summer of 2013 and be
completed by spring of 2014.
2. HISTORY
The Water Department periodicity replaces pumping stations as they come to the end
of their useful life. Stockholm Booster Station replacement was completed in
September 2010. Funds are now available to move forward with another station.
Donner View Hydro Pneumatic Station was built in 1972. The building and pumping
system are at the end of their useful life and need to be replaced. Since the late
1970's, other public agencies have also used the building for radio and phone
equipment which impacts the ability to make improvements.
3. NEW INFORMATION
The proposed new pump station will consist of a block building with two rooms; one
room for the new pumping equipment and the other room for the radio equipment. The
new pumping system will utilize variable frequency drive units (VFD) with high
efficiency pumps and motors replacing system single speed pumps and hydro
pneumatic. The new pumping system will be upsized from 500 gpm to 1500 gpm to
meet the current fire flow demands in the area. The electrical service will be upgraded
from overhead to underground and sized to accommodate the larger pump capacity.
Staff is working on pump system specifications, as well as building, piping, and
electrical system design. Once completed, the bid process will start. The project will
largely be completed with District labor. The foundation, concrete, block work, and
roofing system will be outsourced. Design work is schedule for March, required bidding
in April and dirt work will begin in May or June. Final completion of the project is spring
of 2014.
4. FISCAL IMPACT
The Water Department has allocated $325,000 for this project. The Donner View
Hydro Station Rebuild was not included in FY12 or FY13 Budgets. The planned
funding source is the Water Department Capital Replacement Fund and the
Conservation Budget's wire to water fund.
