In 1964 Whitman and Howard, an Engineering and Architectural Firm, was hired by the newly established Sewer Commission to design a complete sewerage system for the Town of Trumbull. The study was necessary; as sanitary sewers did not exist within the town. All sewage was disposed by individual means such as septic tanks and leaching fields. Due to growing population densities in some areas and poor soil conditions in others, the town was experiencing many difficulties with failing individual systems.

In 1967 a master plan for a town-wide sewer system was completed. The first construction was completed in 1973 and provided sanitary sewer service to neighborhoods in the Main Street, Church Hill Road/White Plains Road sections with extensions that enabled sewers to service all of our commercial and industrial zones.
