The Pumping Division operates the low lift (raw water - pictured at right) and high lift (finished water
- pictured below) pumping units. The six low lift pumps, with a daily rated capacity of 130 million gallons, take water from the intake system and pump it to the treatment plant. Eight high lift pumps,
with a daily rated capacity of 142 million gallons, pump the finished treated water to the distribution system. Water plant operators, working rotating shifts on a weekly basis, provide around the
clock supervision. The master mechanics maintain and repair the pumping units, hydraulic and electric controls, instruments, electric switch gear, standby engines, heating plant, pipe systems, buildings
and grounds.
The division operates and maintains four booster pumping stations with seven pumps, two 4.9 million gallon storage tanks, one 5 million gallon storage tank and one 7.5 million gallon storage tank.
All equipment is remotely controlled over leased telephone lines to maintain pressure in the distribution system. The Division also provides pumping to the Northwest Water Commission, and remotely
controls an in-line booster station with three booster pumps and control valves at the Northwest Water Commission reservoir located in Des Plaines.
