Westland Reservoir and Booster Pump Station

The project entails constructing the initial phase of a 2.5 mg steel reservoir, including its foundation and accessories, as well as a three-zone booster facility. The scope encompasses various elements such as site preparation, infrastructure, retaining walls, perimeter walls, access gates, roads, drainage improvements, and landscaping. It also involves the installation of a reservoir fill pipeline, overflow pipeline, discharge pipeline, cathodic protection, painting, and level controls.

Additionally, the project encompasses the construction of three new booster pump stations, each serving a different zone. This includes the installation of pumps, motors, variable frequency drives (VFD), hydropneumatic tanks, discharge and suction piping, isolation and pump control valves, and associated electrical and control components. A gas chlorination system, enclosure, cylinders, pumps, valves, safety components, sprinkler system, analyzers, and related accessories will also be incorporated. New electrical infrastructure, instrumentation, and programming are part of the project scope, including primary and secondary electrical services, a pre-engineered electrical building, motor control centers, programmable logic controllers (PLC), remote telemetry units (RTU), antennas, and PLC programming.

Temporary improvements to Westland Road were planned, involving clearing, grubbing, landscaping, grading, drainage enhancements, and surface treatment using ABC material. Finally, the project includes the installation of three new 24-inch ductile iron water transmission mains to serve each zone, comprising pipe wrap, isolation valves, bedding, backfill, and restrained joints.
