The $1.36 million Village of Algonquin Braewood Lift Station Rehabilitation project is complete. Delivered in collaboration with the Village of Algonquin and Dahme Mechanical Industries, Inc., the project was completed on schedule and within 1.4% of the original construction contract amount. Following a 2022 condition assessment by Trotter and Associates, Inc. (TAI), improvements were identified to increase lift station and force main capacity. The force main replacement was completed in 2024, followed by lift station rehabilitation and system integration. Improvements included upsized pumps, VFDs, and piping; replacement of the grinder, flow meter, and odor-control equipment; electrical and HVAC upgrades; and connection to the new 16-inch force main. Station capacity increased from 1,500 GPM to 5,000 GPM, supporting future Village development.

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.

The City of Woodstock is continuing to enhance its aging infrastructure through its Gould Street Water Main Replacement project. Once complete, the project will have replaced and upsized a quarter mile of water main from 4” to 8”, which reinforces the system's operation and longevity. Various storm and sanitary sewer point repairs were also completed to ensure all underground improvements within the roadway were completed before resurfacing and reconstruction of the various roadways.

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.

Trotter and Associates, Inc. (TAI) continues its partnership with the DuPage County Department of Stormwater Management on the rehabilitation of the West Lobe Pump Station at the Elmhurst Quarry Flood Control Facility. This critical infrastructure serves as a flood control system by storing excess flow during major rain events and later pumping stormwater back to Salt Creek once conditions recede.  Independent Mechanical Industries, Inc., and their subcontractors are on schedule for the West Lobe Pump Station to be returned to service this fall. Over the last several months, the team completed installation of four 500-hp pumps and rehabilitation of the discharge piping supports along the 100-foot quarry highwall. Additionally, the pump station’s electrical system was upgraded with a 2,500-amp switchboard and VFDs to provide a long-term reliable electrical system for the facility.
