City of Sycamore – Well 7 Radium Improvements Project

By Mark Dupree • November 25, 2024
In 2019, Trotter and Associates was engaged by the City of Sycamore to complete a Water Master Plan, which identified the need for improved radium removal. The plan outlined several options to meet this need; ultimately, the City moved forward with using a hydrous manganese oxide (HMO) filtration system. This filter will be integrated into the existing water system at the City’s Well 7 site, which is installed within a new structure. In addition to the filter, this structure will also house the new chlorine feed, chemical feed/mixing, and electrical system, which are being replaced as part of the project. With the filter being delivered to the site in early July, construction of the project is on track to allow the facility to be operable by the Fall of 2024.

Algonquin Biosolids Handling Improvements Project

By Mark Dupree • July 30, 2024
The Village of Algonquin teamed with Trotter and Associates to upgrade the sludge dewatering process at their Wastewater Treatment Facility. This project is currently in the design phase, which includes replacing the Villages aging belt filter press with two decanter centrifuges. To support this operation, new sludge feed pumps, conveyor, polymer feed system, and a non-potable water filtration system will be installed. The new centrifuge system provides the Village with a reliable, redundant, and self-contained dewatering process, which will improve the overall operation of the facility.
