Previously, Trotter and Associates completed a Wastewater Facility Master Plan for the Village of Roselle’s Joseph L Devlin Wastewater Treatment Facility. The plan identified four essential projects: Plant Expansion and Phosphate Removal, Grit Removal Rehabilitation, Secondary Clarifier Replacement, and UV Disinfection Conversion.

Each project identified above is interrelated and will allow the facility to meet new regulations, support Village growth, and upgrade aging infrastructure. To provide the village with the best financial and operational benefit, these projects were combined into one WWTF Plant Expansion and Nutrient Removal Upgrades project.

With preliminary engineering complete, the Trotter team is working on the final design documents for the project. This phase is expected to be wrapped up in the first quarter of 2026, with bidding and construction to follow.
