Parkway Wastewater Treatment Facility

Stiver Engineering completed the engineering and contract administration of the 10 MGD facility for the Washington Suburban Sanitary Commission in Washington, D.C. Improvements included rebuilding the trickling filters and the addition of sludge handling equipment. Sludge was incinerated using two fluidized bed furnaces, and additional effluent quality was achieved by the use of mechanical filters to remove those solids that might settle.
