CURRENT PROJECTS
The second phase of improvements to Batavia’s Wastewater Treatment Facility was broken into two sub-phases: Phase 2A Rehabilitation and Phase 2B Expansion. IHC began construction for Phase 2A on September 18 th , 2023, and will continue through 2026. This project includes intensive offsite utility replacement and realignment, bike path realignment, demolition of several large structures within the Facility, replacement of the excess flow facilities, construction of new Headworks including screening, grit removal, and odor control, construction of a new primary clarifier diversion structure, four 68’-diameter primary clarifiers, and a Primary Clarifier Control Building, construction of three new duplex raw sewage pump stations, rehabilitation of the three final clarifiers, construction of a new UV disinfection building, and replacement of the WAS thickening systems.
The Village of Fox Lake engaged Trotter and Associates, Inc. to design and construct a new roadway for the Lakefront Park redevelopment initiative. Valued at approximately $1.4 million, this undertaking will serve as the primary means of access for the residents and businesses along Nippersink Road, adjacent to Lakefront Park. The project also includes new water main improvements installed to bring municipal water to the residents and businesses and updates to the stormwater utilities within the area. Construction began in June 2023, and the roadway opened to the public in November, achieving Substantial Completion. The project has reached Final Completion, with the overall cost being about $20,000 under budget.
Trotter and Associates is continuing to assist the City of Woodstock with the management of their Water Main Replacement Program. This $3.4 million project will provide a significant upgrade to a half mile of the Pleasant Street corridor. The existing 6-inch aging water main is being upgraded to an 8-inch, including replacing all lead water services from the main to the house. Additionally, to improve drainage of this area approximately 2,600 feet of storm sewer is being installed. Upon completion of the utility installation, the entire section of the roadway will be rehabilitated, with a mix of full reconstruction and traditional mill and overlay.
Trotter and Associates is continuing to assist the City of Woodstock with the management of their Enhanced Streets Program. The TAI team worked closely with City Staff to develop the scope of work for the 2024 improvements, which included reviewing pavement condition data, pavement cores, and considerations for the upcoming improvements to the Route 47 corridor. In 2024, over 6 miles of local residential, arterial, and light industrial streets will be improved. These improvements include both cement-stabilized reconstruction and the traditional mill and overlay. Additionally, various curb, sidewalk, and utility improvements are being completed. This project is on track to be finished in the fall of 2024.
Trotter and Associates was retained by the Village of Glendale Heights for engineering led design-build services for their Mill Pond Lift Station. Work included the replacement of the station’s pumping and electrical systems and the rehabilitation of the existing wet well. With the project directly adjacent to Klein Creek, the team had to complete extensive permitting and monitoring of construction activities to ensure the watershed wasn’t impacted as a result of the project. The station was recently returned to service, and the project is anticipated to be completed in the early fall of 2024.
The Village owns and operates two wastewater treatment plants and has evaluated their options for upgrading each plant or consolidating their two plants to meet more stringent effluent limits. The Village recently partnered with Trotter & Associates to design the improvements. The Plant Consolidation Project consists of expanding and upgrading nearly every unit process at the North WWTP, constructing a 28 MGD Pump Station at the AJL WWTP property (including screening and grit removal), decommissioning the AJL WWTP, and constructing roughly two miles of dual 20" force main. The expanded North WWTP will feature the construction of a new screening facility, new excess flow clarifiers, expanded aeration basins with biological nutrient removal, an eighth final clarifier, a new advanced treatment building, and a new Administration and Maintenance building.
Trotter and Associates are working with the Village of Roselle to design and implement improvements at their J. Botterman Sewage Treatment Plant. The project includes replacing the existing screening equipment within the Headworks Building, converting the existing oxidation ditch biological process to an AlternatIR Carrousel process for biological nutrient removal, and rehabilitating the Final Clarifiers. The project is in the final design phase, and construction is expected to begin in 2025.
Trotter and Associates is working with the Village of Glendale Heights to upgrade and rehabilitate two pumping stations, with a substantial completion date anticipated in Fall 2024. Both stations receive water from the DuPage Water Commission. The Burdette West Pumping Station Rehabilitation involves removing and replacing the station envelope, process systems, electrical equipment, and site piping. The Brandon Court Booster Station is an inline pressure boosting station on the community’s north side, which increases pressure from the DWC supply to system pressure. Rehabilitation includes the replacement of the four pumps, valves, electric and control systems, and chlorination equipment.
