The City of St. Charles is nearing completion of phase one of the Well No. 8 Water Treatment Plant (WTP) Rehabilitation Project, which includes upgrades to piping, valves, and treatment systems—specifically ion exchange and HMO filtration processes that support radium removal and hardness control. These improvements build on the City’s already high-performing water system and help maintain consistent water quality. Phase two will begin this fall and will include installation and commissioning of the Well No. 14 pump, replacement of the pump at Well No. 8, and electrical and other minor facility upgrades to WTP No. 8. Once complete, these enhancements will increase the available water supply, improve operational flexibility, and strengthen long-term system reliability for the community. 

Construction of a new municipal water well within the City of St. Charles’s outer pressure zone has begun. Municipal Well and Pump is halfway through drilling the 1,300-foot deep well into the Galesville Aquifer. This project is part of a broader effort to strengthen the City’s water supply system, which includes improvements to the existing water treatment facility and construction of a raw water main between the two facilities. The Trotter team supported the City through well siting, securing EPA funding, designing flow-balancing solutions for the treatment plant, assisting with bidding, and overseeing well-drilling operations. Once complete, the new well will increase available water supply and allow the City to fully utilize the treatment plant’s design capacity. 

The Village of Algonquin’s Water Treatment Plants No. 1 and No. 2 Aerators and Roof Replacement project is nearing completion. With the new aerators operational, the Village will more effectively oxidize contaminants, enabling the facility to continue providing high-quality water to the community.  The new aerators also enhanced the facilities' capabilities and minimized objectionable odors. WTP No. 1 is a vital facility and cannot be taken out of service. This required careful planning and communication among the team to ensure uninterrupted operations. Close coordination between the Village of Algonquin, Trotter and Associates, and Keno and Sons Construction Company enabled the project to be successfully sequenced and completed within budget.

Trotter and Associates, Inc. has delivered a comprehensive series of municipal infrastructure upgrades in Woodstock, IL, over a multi-year period.

The Janak and Weck subdivisions, located in the Village of Algonquin, are older subdivisions within the municipality. The Village is looking to provide residents with long-term sustainable solutions to update its existing aging water and sewer infrastructure. To achieve this goal, the Trotter team is preparing a feasibility study that outlines the best options for improving the infrastructure in these subdivisions. One of the main components will be assessing whether to rehabilitate the existing rear-yard sanitary sewers or to replace the sewers within the right-of-way in front of the properties. Once the study is completed, the Village will have the data needed to make an informed decision that results in the most cost-effective, sustainable infrastructure plan for this area.
