Municipal Water Authority of Aliquippa – Water Filtration Plant

LSSE provided surveying, design, permitting, bidding, and construction phase services for a 5.76 MGD water filtration plant. LSSE led the design team in completing all Mechanical, HVAC, Structural, Civil, Environmental, and Electrical design for the water filtration plant. The design scope of work included pilot testing, raw water analysis, design, permitting, bidding, and construction-phase services for an iron- and manganese-removal pressure filtration process to treat raw water from the existing MWAA groundwater well field. The proposed water filtration plant replaces the existing MWAA water softening plant, originally constructed in 1941.

The design includes the construction of a new above-ground raw water storage tank for chemical injection (chlorine and sodium permanganate) to physically oxidize iron and manganese. The filtration process is comprised of a continuous regeneration catalytic oxidation greensand pressure filtration system designed for the removal of iron and manganese. The filtration process also includes pumping systems to convey water through the filtration plant, with discharge of treated water to the clear well. In addition to iron and manganese removal filtration equipment, the new water filtration plant includes a laboratory, bathrooms, operation staff locker rooms, and plant/distribution control systems.

Construction of the new water filtration plant addresses MWAA’s Pennsylvania Department of Environmental Protection (PaDEP) Administrative Order and allows MWAA to continue to provide regulatory-compliant potable water to a regional customer base that includes the City of Aliquippa and contiguous portions of Hopewell, Raccoon, and Potter Townships.
