Hurricane Ike Lift Station Rehabilitation
As a result of Hurricane Ike, the City of Galveston’s existing Lift Station No. 1 suffered considerable equipment and controls damage resulting in total operational failure. As one of the largest stations within Galveston’s sanitary sewer collection system, the failure of this facility threatened the public health, safety, and welfare of the citizens it served, as it directly contributed to a build-up of untreated sewage. In addition, its failure has resulted in nearly two years of bypass pumping operations by the City of Galveston to maintain essential wastewater conveyance and treatment services for its residents.
LAN designed the lift station rehabilitation to ensure its future of continuous operation with uninterrupted service. Design improvements included: a refurbished wet well; reconfiguration of the lift station from wet-pit/dry-pit to submersible wet-pit operation with variable frequency drives; piping, valves, and fittings; a new automatic coarse screen and associated screenings discharge screw compactor; and a new permanently-affixed, diesel-fueled generator with automatic transfer switch.
The project also included a pre-engineered enclosure to house all electrical and controls components associated with the station, which is designed to withstand Category 5 hurricane wind loads and is located above the 500-year floodplain.
