Wastewater Treatment

The Wadsworth Wastewater Treatment Plant employees' goal is to maintain or improve the quality of the receiving stream by insuring a quality effluent through smart operations. Even with records amounts of precipitation in 2011, the plant performed quite well in meeting the limits of its NPDES permit. Access the NPDES application (PDF) or the NPDES fact sheet (PDF).

In 2011 the wastewater treatment plant released over one billion, four hundred seventy million gallons of treated effluent to the plant receiving stream, River Styx. Over the course of the year, the plant operated at an average of 80.6% design capacity (average daily flows of 4.04 millions of gallons a day vs. 5 millions of gallons a day design). Snow melt and rains put the plant at 112% of capacity in March and heavy rains had the plant operating at 114% capacity in May.

Rules & Regulations

All employees in the plant are required to be licensed operators by the end of 2012, and 3 of the 4 operators have already completed that requirement. Other staff includes Wastewater Division Superintendent John Clark and lab technician Penny Schwanger. View the sewer rules and regulations (PDF).

Phosphorus

Under the plant's current permit, phosphorus may be released in the effluent at no more than 1 milligrams per liter. In 2011, design was completed by Burgess and Niple for the new chemical feed system facilitates increased phosphorus removal from the plant effluent. The project was bid and contract awarded to Workman Industrial services of Kent, Ohio.

Phosphorus is a nutrient found in wastewater that can cause excess algae growth in streams. If remained unchecked, these blooms can cause odors and consume dissolved oxygen during decomposition. In a worst case scenario, human health can be impacted as demonstrated by the situation at Grand Lake St. Marys. While chemical addition is a proven and reliable method of removing the phosphorus, plant operators are experimenting with plant process' to remove the phosphorus biologically.

Pretreatment

The City monitors water pollution control; and, in doing so, requires manufacturing and other facilities to complete a Pretreatment Survey Questionnaire.

Fats, Oils, & Grease

Interceptors shall be provided when, in the opinion of the Director of Public Service, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts or any flammable wastes, sand or other harmful ingredients.

The City of Wadsworth has adopted the updated Rules and Regulations of the Medina County Department of Sanitary Engineering, Chapter 6, Section 6.5, Fats, Oils and Grease, as the standard for grease and oil interceptor requirements. Food Service establishments are required to complete a survey regarding their compliance with these regulations.
