 Boyle's
design capabilities for pump stations entail civil, electrical, mechanical,
and structural engineering; instrumentation and controls; and architecture. Often, we’re responsible for all such disciplines in a single project,
as was the case for the multiple-award-winning Foothills and River Mountains
pump stations in Las Vegas, Nevada.
Large,
140+ MGD Pumping Stations in Southern Nevada
 The
Foothills Pumping Station is a 150-MGD facility that contains
seven 2500-horsepower centrifugal pumping units, while River
Mountains is a pumping station with five 3500-horsepower pumps
capable of delivering a combined total of 140 MGD.

New
Pump Station Meets Demand of Growing District  Boyle
designed the 980-2 Pump Station for Otay Water District (OWD)
in San Diego County. The new pump station, with five 600-horsepower,
5,000-gpm vertical turbine pumps, supplements the District’s
potable water system and helps meet the needs of an area where
demands have recently grown by 11 percent.
The maximum static lift for the 980-2 Pump
Station is 374 feet. (Boyle’s design provided for a
sixth pump to serve as a standby in the event that any one
pump is temporarily shut down for repair or maintenance.)
The 980-2 Pump Station is housed in an 80-foot-by-80-foot
building on a one-acre site adjacent to the 30-MG Eastlake
Greens Reservoir.  A surge analysis was performed during the
design of the 980-2 Pump Station; the accumulated data helped
to determine the effect of transient conditions due to a
power outage and additionally determine the facilities required
to mitigate any resulting adverse pressures.
The Otay Water District (OWD) is a publicly
owned utility whose service area encompasses 129 square miles
in southeastern San Diego County. District facilities serve
the water and/or sewer needs of approximately 143,000 people.

Water
Supply and Distribution
Both pumping stations have an intake
forebay with a capacity of more than 2 MG, pump discharge
piping with associated hydraulically actuated cones valves,
a surge-protection system, an innovative cooling system,
and a SCADA system that allows for remote-control operation.
