Ocean View Regional Wastewater Pumping Station. Sussex County, Delaware.
The project included an innovative review of the County’s existing system which eliminated the construction of approximately 9,000 LF of force main by maximizing the use of existing infrastructure to the County’s Wastewater Treatment Plant. The project included three 215 horsepower submersible pumps, a valve vault for pump check service valves/surge relief valves, monorail for pump removal, 500 kW emergency generator, maintenance building housing electrical/control room, maintenance area, generator room, architectural treatments, variable frequency drives, and odor control facilities. The project included the excavation and construction of a 40 by 60 foot wet well at a 33 foot depth within close proximity to residential dwellings. The project received an award from the Delaware Chapter of the Association of Builders and Contractors.
