Wastewater Treatment Case Studies
Hulls Cove Sanitary Sewer Extension—Bar Harbor, Maine
The National Park Service contracted with the Town of Bar Harbor to construct a sewer main from the Town’s Hulls Cove sewer collection system to the Acadia National Park Entrance. Aquarion designed the extension and managed its construction. The extension involved the blasting and excavation of approximately 1,000 cubic yards of ledge and the installation of over 1,500 feet of eight-inch diameter heat-traced, insulated, ductile iron pipe, sixteen pre-cast manholes, and an automatic control system for the heated pipe. Despite the complexity and scope of the work, Aquarion completed the project on time and four percent under budget.


Commercial Street Pump Station Upgrade Design and Construction, Bath, Maine
1999-2001 (Site Design and Construction)

AQUARION was contracted by the City of Bath, Maine to develop a comprehensive plan to improving wastewater pumping capabilities at the City’s largest pump station and reducing the largest source of CSO events within the City. Various alternatives were developed and evaluated. The selected alternative was to increase the pumping capacities at the Commercial Street Pump Station utilizing different pumps sized for normal design flows and wet weather flows, extending the existing force main to bypass re-pumping the wastewater at the Front Street Pump Station, and down-sizing the Front Street Pump Station.

After regulatory acceptance of the program, AQUARION completed the design of the upgrades to the Commercial Street and Front Street pump stations. The Commercial Street Pump Station was upgraded to 8,100 gpm. The project entailed the construction of a brick and masonry addition to the structure, installation of two centrifugal dry weather pumps and two centrifugal wet weather pumps, PLC controls integrated into the City’s WWTP PLC package, back-up power generation, miscellaneous piping and monitoring modifications, and a number of structural, heating and ventilation improvements to address building code and safety deficiencies. The force main extension consisted of the installation of 1,500 linear feet of 24-inch ductile iron force main, and the reconstruction of the road way and sidewalks in the impacted area. The Front Street Pump Station was converted to a two pump application utilizing self-priming pumps with flood suction lines. The Front Street Pump Station upgrade also entailed building, heating and ventilation modifications for code and safety improvements.

AQUARION assisted in the preparation of successful Maine SRF loan funding as well an Economic Development Initiative Grant for the project. AQUARION is currently providing construction phase engineering services
