City plans to install UV system to replace its chlorine disinfection system
RJN Group Inc. (RJN), headquartered in Wheaton, Ill., recently was awarded a $1.3 million design-build project for the city of Collinsville, Ill. The project, which includes designing and installing a UV disinfection system, is Collinsville’s first project using the design-build project delivery method.
The UV disinfection process is the next phase of the Collinsville Wastewater Treatment Plant expansion project. The treatment plant currently uses a chlorination disinfection system for the secondary treatment of the wastewater. The city has decided to eliminate the chlorination disinfection system and replace it with the UV disinfection system.
UV disinfection is a physical process rather than a chemical process, which eliminates the need to generate, handle, transport or store toxic, hazardous or corrosive chemicals. Other benefits to using this system include fewer harmful residual effects to human or aquatic life, user-friendliness and a smaller footprint.
The city accepted RJN’s value proposition based on consideration of the core design-build principals: reduced owner’s risk, schedule acceleration and better value for the ratepayers.
Design-build simplifies project delivery via a single contract between the city and the design-build team. RJN will lead the design-build team and provide the design services and project management. Korte & Luitjohan Contractors will provide the construction services. By utilizing the design-build method, the project delivery is anticipated to be 10 months faster than conventional project delivery of design-bid-build, and result in a significant cost savings. Work on the project has begun and substantial completion is scheduled for late summer 2011.
