February 2015 – For its innovative and complex design to modify and expand the City of Belleville Water Reclamation Facility, TWM has received the 2015 Engineering Excellence Honor Award in Waste and Storm Water from the American Council of Engineering Companies – Illinois. The Honor Award signifies the top project in the category on the state level, demonstrating exceptional engineering that meets the needs of the client and benefits the public welfare.
For this project, TWM collaborated with the City of Belleville to develop a Long-Term Control Plan for Combined Sewer Overflows (CSO), as required by the Illinois and U.S. EPA. The first, and largest, phase of this plan included an expansion of and modifications to the existing Water Reclamation Facility. The primary purpose was to improve water quality by addressing and reducing the City’s CSO issues. Throughout the project, TWM used green technologies for energy efficiency and to reduce the environmental impact of the City’s effluent to the greatest extent possible.
The firm also implemented cost-saving measures to minimize the user charge increase. Through innovative thinking, TWM engineers re-purposed existing components, such as converting existing sludge lagoons to CSO management basins, instead of resorting to all new construction, thus reducing the overall impact on sewer rates.
The final design increases treatment capacity by more than 50% from 8.0 to 12.4 million gallons per day to support growth and development in Belleville.
In addition to winning the state award, the firm will receive a National Recognition Award at the ACEC Engineering Excellence Awards Gala in Washington, DC in April. There it also will have the opportunity to compete for a top award on the national level.
