The Village of Addison is implementing a major project to separate combined sewers in the Home Addition area, which is the largest remaining combined sewer tributary in the community. The project includes separating the area's existing combined sewer system, which currently manages both wastewater and stormwater runoff, into separate sanitary and storm sewer systems. About three miles of new storm sewer, ranging from twelve to sixty inches in diameter, will be installed and directed to Salt Creek through an existing 84-inch relief storm sewer. To connect to the existing 20-foot-deep relief sewer, two custom-made junction chambers (10-foot by 12-foot and 8-foot by 10-foot) have been installed. Another key part of the project is building a stormwater detention facility at Cherokee Park, which is the lowest point of the drainage basin and the area most vulnerable to flooding. Since June of 2025, the contractor has completed approximately two and a half miles of storm sewer installation. The remaining sewer work and excavation of the detention pond are expected to be finished in the coming months. Along with storm sewer upgrades, lead water services found during construction are being replaced. So far, 65 lead water services have been taken out of the Village's water system. Once finished, the Village’s sanitary sewer system will experience significantly lower flows during wet weather. This decrease in flows will help prevent basement backups, street flooding, and combined sewer overflow discharges previously suffered by the Village. The project will also lessen the volume of stormwater runoff treated at the AJL Wastewater Treatment Plant. It remains on schedule and is expected to be completed by summer 2026. 

Phase 2 of the Village of Fox Lake's Lead Service Line Replacement Program is nearing completion. This program aligns with the 2024 updates to the EPA's Lead and Copper rules, which require water providers to begin replacing lead and galvanized water service lines. The original water system in the project areas dates back to 1929, when lead water services were common. To comply with regulations, all lead and galvanized water services are being replaced from the water main to the customer's meter inside the house. Both phases of this program are funded through the IEPA's Public Water Supply Loan Program, in which the Village has received principal forgiveness for the entire $5.1 million loan. To date, the program has replaced approximately 350 water services, and Phase 2 is expected to be completed by June 2026. 

The $42.6 Million Phase 2A Rehabilitation project at the City of Batavia's WWTF is nearing completion, several months ahead of schedule and with less than 0.5% in change orders. After completing off-site utility and roadway replacement, bike path realignment, replacement of the process flow disinfection system, and rehabilitation of the final clarifiers, wastewater was completely transferred over to the brand-new Headworks and Primary Clarifiers in October 2025. This project’s success is a result of the outstanding dedication and collaboration of the General Contractor IHC, the City of Batavia Public Works staff, and our Trotter project representatives. We sincerely thank everyone for making this achievement possible!

The City of Saint Charles has completed Sequence #1 of the Ohio Avenue and Kautz Road Raw Water Main Installation Project, advancing critical water infrastructure improvements. The work included installing a new raw water main between Well No. 8 and the future Well No. 14, along with other key infrastructure components and roadway restoration. Most of the water main was installed using horizontal directional drilling to minimize surface impacts and limit disruption, and hydrants were installed by open-cutting. Trotter and Associates supported the City by securing EPA funding, designing the water main alignment, assisting with the bidding process, and observing construction in cooperation with City staff. 

Trotter and Associates, Inc. provided start-to-finish engineering services to the Village of Fox Lake for their 2025 Motor Fuel Tax (MFT) Roadway Improvement Project, delivering support from initial conceptual design through final construction closeout. The project rehabilitated over one mile of Village roads using a strategic mix of reconstruction and resurfacing techniques. The team’s expertise allowed the Village to make the most of its MFT funds while meeting critical infrastructure needs. By utilizing full-depth pavement reclamation with cement in conjunction with conventional milling and resurfacing operations, the Village successfully addressed underlying subgrade deficiencies in critical areas while extending roadway rehabilitation across multiple streets throughout the community, within the established project budget. Trotter and Associates, Inc.'s comprehensive approach ensured efficient project delivery, regulatory compliance, and optimal utilization of available funding resources for this essential infrastructure investment.
