meet small demands. The main pumps will be controlled by variable frequency drives
(VFD) to provide constant pressure to the system.

Automatic filtration will also be included on the skid, downstream of the pumps. This filter
will prevent debris from entering the irrigation systems and help avoid clogging sprinklers
or valves. The automatic filtration system will backwash debris from the filter screen.
Typically, this water is discharged back into the storage reservoir, away from the intake
screen.

Raw Water Pumping Stations:

Willow Creek Pump Station (Phase One)-
The Willow Creek pump station will be located within Willow Creek Park adjacent to one
of the three conceptualized new storage reservoirs in the flood drainage basin. The
water storage capacity of the ponds at this location is approximately 8.4 acre-feet.
.Based on the preliminary hydraulic model, the pump station at this location will provide
approximately 1,511 GPM at a discharge pressure of 90 PSI.

West Well Pump Station (Phase One) -
The West Well pump station will be located at the Escondido Park site adjacent to the
existing well water source. The water storage capacity of the pond at this location is
approximately 6.99 acre-feet. .Based on the preliminary hydraulic model, the pump
station at this location will provide approximately 1,234 GPM at a discharge pressure of
90 PSI.

Ballfield Pump Station (Phase Two) -
The Ballfield pump station will be located at the site of the existing ballfield pumping
station at Fifth Street adjacent to a new storage reservoir to be constructed on City of
Lamar property at this location. The water storage capacity of the pond at this location is
approximately 42.62 acre-feet. .Based on the preliminary hydraulic model, the pump
station at this location will provide approximately 7,714 GPM at a discharge pressure of
90 PSI.

South Hill Pump Station (Phase Three)-
The South Hill pump station will be located at the existing storage ponds at the south
end of the City. According to Dannie MacMillan, the water storage capacity of the
existing ponds at this location is approximately (9 million gallons). .Based on the
preliminary hydraulic model, the pump station at this location will provide approximately
3,024 GPM at a discharge pressure of 90 PSI.

West Pump Station (Phase Four) -
The West pump station will be located at a property owned by the City of Lamar to the
west of Fourteenth Street, and adjacent to the Fort Bent Canal. A new storage reservoir
will be constructed on City of Lamar property at this location. The water storage capacity
of the pond at this location is approximately 19.6 acre-feet. .Based on the preliminary
hydraulic model, the pump station at this location will provide approximately 3,548 GPM
at a discharge pressure of 90 PSI.
