ST. CHARLES – The city's west side wastewater treatment plant is nearing capacity.
At their Aug. 5 City Council meeting, aldermen approved a $2.6 million engineering contract with Trotter and Associates, Inc. to design a bigger treatment plant. The plant currently functions at 700,000 gallons a day and is reaching capacity to serve existing customers and future development.
The expansion will increase capacity to 1.05 million gallons a day, which will accommodate future growth and ease the demand being placed on the current facility, said Tim Wilson, the environmental services manager for the city's public works department.
Wilson said the project will require an upgrade of the biological wastewater treatment process to address recently promulgated and pending environmental regulations.
"The regulatory demands that will be addressed within this section include: nutrient removal, phosphorus removal, suspended solids effluent requirements, bio-solids stabilization and several other regulated treatment capabilities," he said.
The design of the expanded facility is expected to be completed by April 2020. The project will be funded through the Illinois Environmental Protection Agency's low interest loan program and Trotter and Associates will prepare a low interest loan application as part of its work.
