up to 24 million gallons per day (MGD)
thanks to the four 250-horsepower vertical
turbine pumps. Figure 1 shows two of the
four pumps installed, and adjacent to the
pumps is the erected framework for the
new chemical storage building.
The RWPS is designed to utilize
water from the Tertiary Treatment facility
and the Membranes and Ozone Facility.
Water is chemically disinfected before it is
delivered to its final point of use. Sodium
hypochlorite is stored in two 10,000 gallon,
12-foot diameter reinforced fiberglass
polyester tanks, Figure 2.
Water is conveyed underground via
two 36-inch diameter discharge pipes. The
flow is delivered to the FWRC East and
West campus processes and to reclaimed
water customers, Figure 3.

This most recent investment by
CCWRD in its existing reuse water
facility is a perfect example of the ongoing
dedication and commitment being shown
by more and more water and wastewater
agencies to conserve and maximize the use
of available water supplies. Construction
on the pump station is scheduled to be
completed early 2021 and should be in
operation by late spring.
Reclaimed water offers vast potential
for maximizing the use of available water
supplies due its versatility to be used in
different ways. This has been effectively
demonstrated in Las Vegas, as well as
other communities in the Southwestern
United States that are developing strong
reuse programs and finding creative
ideas to meet increasingly higher
water demands in their communities.
Southern Nevada is one of the driest
places in the United States, and with
its population of 2.1 million residents
expected to continue growing, the
region is poised to continue its legacy as
a forward-looking community in water
conservation and reuse.S
