DISCUSSION
Background
The City has over 180 miles of pipeline providing potable water to the community. These
pipelines are connected to water storage tanks around the City. The City’s water storage is
provided in 11 tanks and two reservoirs in various locations. The tanks range in size from
40,000 gallons to 7.5 million gallons. The two reservoirs are a combination of above -grade steel
tanks and underground concrete reservoirs with a total combined storage capacity of
approximately 26 million gallons. Regular maintenance of water storage tanks is important for
economic, environmental, and health reasons.
This project will install a new Pressure Regulating Valve (PRV) at the northeast corner of the
Terrace Hill tank site. The PRV will be connected to the existing 16-inch diameter pipe fro m the
High-Pressure Zone in Bishop Street. A new 16-inch pipe will be constructed to connect the
PRV to the Terrace Hill Zone, traversing Bishop Street and tying into the existing 16 -inch
diameter pipe line in Boulevard del Campo. This project will improve water quality in this zone
by providing connectivity.
