172nd Street 2 MG
Reservoir and
Booster Pump Station
Gilbert,
Arizona
As part of the 2
Million Gallon Reservoir and Dual Zone Booster
Pump Station project, an existing irrigation
well at Baseline Road and 172nd Street was
analyzed for water quality and capacity. A
cost benefit analysis was performed to determine
the practicality of rehabilitating the existing
well versus constructing a new well. As a
result of this analysis, the structurally
degrading existing well was abandoned and
a new well was drilled onsite to provide a
quality water source. The 2-million gallon,
cast-in-place, "hopper bottom" reservoir
receives water either from the new well or
directly from the Town's water system. System
fill can be programmed to occur at night during
low demand periods and pumped back into the
system during demand peaks. The booster station
has a firm pumping capacity of 4,000 gpm,
divided between two pressure zones. It includes
five vertical turbine pumps - three with variable
frequency drives, surge protection, and a
tablet chlorination disinfection system. A
diesel generator provides emergency power
in the event of power loss.
