Title
Facility Water System Treatment and Filter Installation Project
History
The Public Works Department currently maintains closed-loop water HVAC systems at eight (8) facilities: Sportsplex, Police, Village Hall, Franklin Loebe Center, Rec Admin, Civic Center, the Main Pumping Station (MPS), and Orland Park Health and Fitness Center (OPHFC). In these systems, chilled water is generated and then piped throughout a building to other air handling units serving individual spaces or floors. It should be noted that the chiller at the OPHFC will be removed and replaced by a different type of HVAC system in 2025.
To date, a preventative water treatment program for the water-cooled chillers has never been implemented, which has led to system inefficiencies and frequent repairs. Water treatment is important for hot and cold closed-loop systems to prevent corrosion, protect against scale formation, and ensure efficient operation. Untreated systems can lead to water and energy waste, equipment degradation, and increased operational costs. To address these issues, a facility water treatment program and filter installation project is planned for 2025.
Accordingly, Public Works requested a proposal from Midwest Mechanical Group, Inc. (“Midwest Mechanical”), who participate in the Omnia Partners cooperative program (Contract #02-91), to complete Facility Water System Treatment and Filter Installation Project in 2025. The scope of work includes quarterly water tests and treatments of hot and chilled water loops for 2025, an annual summary of the water treatment program including a summary of results and recommendations for future savings, and the installation of side stream filters at SportsPlex, Police Station, Rec Admin and the MPS. A summary of the proposal submitted by Midwest Mechanical, which is based on Omnia Partners Contract #02-91, is provided below:
