Water Pollution Control The Water Pollution Control Center (WPCC) was established in1960 to meet the community’s expanding need for safe wastewater treatment.
The treatment facilities were upgraded and expanded in 1972 to provide for separate pumping of domestic and industrial wastes, grit removal, pretreatment of Industrial wastes, primary settling, activated sludge secondary treatment, and chlorine disinfection of the treated effluent. Provisions for thickening, digestion, and mechanical dewatering of the sludge with disposal to an on-site monofill were also included. The design average flow was 5.25 MGD.
The influent waste stream consists of a combination of domestic and industrial sewage. The two major industrial contributors are Noveon and Ford. Industrial flow for 2003 is estimated to be 24.6% of the plant’s total flow. The Avon Lake Water Pollution Control Center also serves northern sections of Avon. Future plans call for flow from Lorain County Rural Wastewater District (LORCO), which includes Eaton and Carlisle Townships and surrounding property, to be piped north to the Avon Lake WPCC facility. Expansion and improvements will be required to accommodate additional flows from the county and solids from the Avon Lake water plant as the demand for quality water and wastewater treatment increases. A study is now underway to determine the present and future needs of Avon Lake’s Water Pollution Control Center and to develop a master plan for achieving them.

The original plant consisted of a barminutor, raw sewage pumping, grit removal, pre-aeration, primary settling, and chlorination before final discharge to Lake Erie. Design average flow through the plant was 3.4 million gallons per day. 
In 1983, the diaphragm plate and frame filter press was completed for sludge dewatering prior to disposal on-site and in 1995 an ultraviolet light (UV) disinfection system replaced chlorine. The current plant design is rated at 6.5 MGD average daily flow with a maximum storm flow of 12 MGD. In 2003, the plant received an average of 4.7 MGD or 73% of the design flow. During periods of wet weather, the plant has taken up to 12.5 million gallons of wastewater without upset, which represented 250% of average daily flow.
