4.7 BOOSTER STATIONS
Water is conveyed from the lower supply pressure zones to the higher pressure zones via a series
of booster pump stations (
Table 4.4
). There are a total of 12 booster stations in the City and
Table 4.4
lists of their ground elevation, source and destination pressure zones, total pump
capacities, and additional station information.
4.8 PRESSURE REDUCING VALVES
Some pressure zones are served from higher pressure zones through pressure reducing valves
(PRVs), which are summarized on
Table 4.5
. PRVs constructed at pressure zone intersections,
allow the conveyance of water from higher pressure zones to the lower pressure zones in the City.
Additionally, some PRVs provide a source of emergency supply to lower pressure zones in the
case of booster station failure or other operational issue. The City currently operates 16 pressure
reducing valves throughout its water system.
