The Glenbard Wastewater Authority is currently in the process of rehabilitating and upgrading its primary clarification, sludge pumping, and gravity thickening operations. In late 2024, the 2025 Primary Clarifier Rehabilitation project was bid to replace infrastructure that was reaching the end of its service life, as well as to provide better operational controls for the Authority.

This project includes the removal and replacement of both 110-foot clarifier mechanisms and sludge pumping equipment. The new pumps will be on VFD’s to better manage solids within the process and will have the option to be directly fed to the anaerobic digesters.

In addition, the existing gravity thickener will have its equipment removed and replaced. The Authority elected to include launder covers on both clarifiers for odor mitigation and the removal and replacement of the gravity thickener dome with a new flat cover. The project also includes upgrades to the existing electrical equipment and SCADA system and the replacement of diversion structure gates. Construction is underway and is anticipated to be completed in early 2026.
