Construction of the City of Woodstock's 2025 Enhanced Street Program, which improves 8.4 miles of roadway, began last month. These improvements include both resurfacing and reconstruction of local residential/commercial streets, as well as higher traffic volume collector and arterial streets. During the design phase, TAI engineers performed a comprehensive evaluation using pavement cores, PCI ratings, and in-person field assessments to determine the most cost-effective and appropriate improvement for each roadway segment. To maximize value and minimize disruption, cement-stabilized full-depth reclamation (FDR) was selected as the reconstruction method for qualifying streets. FDR recycles the existing aggregate and subgrade materials by blending them with Portland cement and water, creating a strong, stable base ready for paving, without the need to haul in new aggregate. This sustainable approach not only reduces cost and environmental impact but also significantly minimizes disruption to residents. We’re proud to partner with the City of Woodstock in delivering efficient solutions for our municipal clients and their residents.

Trotter and Associates, Inc., along with Manusos General Contracting, Inc., recently completed the Well 7 Radium Improvements Project for the City of Sycamore. This project was guided by the City’s 2019 Water Master Plan, also developed by Trotter, and focused on upgrading radium removal from the municipal water supply. Upgrades included the construction of a new treatment facility equipped with a hydrous manganese oxide (HMO) filtration system. The facility features dedicated rooms for HMO chemical mixing and feed systems, chlorine dosing, and electrical controls. The system was brought online earlier this spring and is now fully operational, significantly improving the City’s water treatment capabilities to continue to provide safe, high-quality drinking water.
Phase I Improvements at the City of Woodstock’s South Wastewater Treatment Plant are progressing on schedule, with the chemical phosphorus removal system expected to come online this fall, marking the first significant milestone of the project. The strong performance of Manusos General Contracting and their team of subcontractors has been key to staying on track. Manusos has led structural concrete work and continues to manage overall construction efforts. RV Builders completed the construction of the ground face masonry block building shell, while Dahme Mechanical Industries installed under-slab plumbing and process piping. Associated Electrical Contractors has completed under-slab electrical work, and Jim Burke Excavating handled earthwork and installation of underground site utilities, including preparation for the new ring road. Upcoming work will focus on the chemical building systems, rehabilitation of the aerobic digesters, and improvements to the oxidation ditch. The project remains on track for final completion in summer 2026. Trotter and Associates, Inc. is proud to support the City of Woodstock with engineering solutions that advance water quality and infrastructure reliability for the community.

The City of Crystal Lake has engaged Trotter and Associates, Inc. (TAI) to undertake a significant rehabilitation project at Wastewater Treatment Plants (WWTP) Nos. 2 and 3. This project aims to enhance the efficiency and effectiveness of the wastewater treatment processes in alignment with the City’s Wastewater Master Plan and recent Phosphorus Removal Studies. The project scope for WWTP2 will involve replacing four raw sewage pumps and the primary clarifier cross collectors, rehabilitating the secondary clarifier, and converting the tertiary filtration process from sand filters to cloth media disc filters. Similarly, the work on WWTP 3 will include rehabilitating both secondary clarifiers and converting the tertiary filtration process. These upgrades are crucial for improving the overall performance of the wastewater treatment facilities and ensuring compliance with environmental regulations. Trotter and Associates, Inc. is currently in the early stages of design, with construction expected to begin in early 2027.

The Village of Barrington Hills has kicked off its 2025 Road Program, which includes HMA resurfacing along three miles of roadway and patching and striping on five miles of various roadways within the Village. With the initial removal completed, crews have begun placing reflective crack control fabric along the milled roadway. Utilization of this fabric on resurfacing projects reduces reflective cracking from the underlying pavement. It acts as a moisture barrier, all of which assist in extending the service life of the roadway. The final HMA surface placement along Spring Creek Road and Buckley Road, patching of various streets, and striping are expected to be completed in the coming months.

The Village of Algonquin, Trotter and Associates, Inc., and Manusos General Contracting are excited to be moving into the construction phase of the WWTF Biosolids Handling Improvements project. With anticipated long lead times for equipment, the project team is working diligently to process submittals to ensure installation of the two decanter centrifuges can begin in the Spring of 2026 as planned. Upon completion of the project, the Village will have met its goal of upgrading the sludge dewatering operation to maintain processing current demands and allow for future development.
