North Fayette County Municipal Authority’s plant treats water from the Youghiogheny River and is comprised of the following unit processes: raw water river intake, chemical pretreatment; rapid mix; flocculation and settling via Claricones; mixed media filters; disinfection via chlorine; pH adjustment; corrosion control; fluoridation; two clearwells; and finished water pumps. The plant was in need of various improvements to continue reliable treatment and service for the next 10 to 20 years. Our study focused on process, structural, civil, electrical, and instrumentation and controls improvements and prepared recommendations based on a risk assessment that accounts for severity of failure and probability of failure. We identified 25 improvements to ensure reliable plant operations during the study including a pump replacement, filter upgrade, new backwash storage tank, and reservoir upgrades.
