Projects - Water Pump Stations
Some
of our Pump Station projects include:
|
|
City of Coquitlam
David Avenue Pump Station
 The
North East Coquitlam area will ultimately sustain a population of
approximately 42,000 people. A series of water distribution system
improvements are required to ultimately supply these demands. The David
avenue pump station forms an integral component of the new supply system
with a capacity of 355l/s, the David Avenue pump station will supply the
equivalent of a 30,000 population.
The station was designed for a 1:465 year seismic event and required
extensive retaining structures. Four vertical turbine pumps with a
capacity of 128l/s @ 106m head were designed to meet the ultimate
demand. Variable speed drives were required to meet the interim demands
and address the high interim system operating pressures, until
additional distribution piping upgrades are completed. The station
static discharge pressure of 210m required 300# flange ratings and
review of all mechanical component design operating pressures.
Station features
included, a 7.0m high pump bay with overhead crane, separate standby
generator room, with a 500kw generator and automatic transfer switch. A
separate motor control room was provided and the station is controlled
with a Modicon PLC and Modbus network. The station communicates with the
City works yard via a Unitec RTU and Johnson 900MHz radio.

Township of Langley East Aldergrove
Pump Station |
 Water
is supplied to the East Aldergrove area of Langley from a series of
groundwater wells, which are treated at the Water treatment plant and
pumped into the surrounding distribution system. In the late 1970’s the
East Aldergrove reservoir was constructed as a 30m high prestressed
circular tank, with common inlet and outlet piping. As a result of this
arrangement only the top one third of the storage volume can be
effectively utilized, without significant HGL drop within the zone.
The East Aldergove booster pump station was designed to draw out of the
existing 1.4MIgal reservoir and boost pressure in the zone, to supply an
ultimate population of approximately 15,000 people while maximizing the
storage volume of the reservoir.
The pump station was designed with four (4) 60 HP duty pumps , and One
standby each rated at 156l/s @ 22m TDH. Peak hour and fire flow
requirements are met through the combination of the four duty pumps,
while a small jockey pump provides low flows.
Architecturally the station consists of concrete block walls, pitch
tapered glulam beams, 4 x 4 tongue and groove wood planking under metal
clad roofing.

City of
Abbotsford Old Yale Boost Pump Station |
The
Old Yale Booster Pump Station, supplies water to the western
portions of the City of Abbotsford, via a new 600mm DI watermain
along the Fraser Highway.
This
expansion includes two additional 200hp VTP pumps and room for a
third spare. An upgrade was undertaken the previous year to add a
single 200hp pump and with the completion of this expansion a total
of three new 200hp VTP pumps will provide fire and domestic
protection to an ultimate population of approximately 20,000 people.
