Cardinal Engineering Associates - 55 years of excellence

Cardinal Engineering was retained by the City of Middletown, Connecticut, to prepare final construction plans and specifications and to provide contract administration and resident engineering services for 13 combined sewer separation projects with a total cost of over $ 25 Million.

The existing sewage and stormwater collection system in the City's Central Business District consisted of combined sewers with an average age of over 100 years. Due to the deteriorated condition of the existing sewers, groundwater infiltration into the system was excessive. In addition, the combined sewers also carried runoff from both roadway and roof drainage systems. The purpose of these projects was to eliminate the combined sewer overflows by designing a separate storm sewer system.

The project involved the construction of 30,000 linear feet of storm sewers to eliminate combined sewer overflows into the Connecticut River. This project also included the rehabilitation of a storm water pump station and construction of a new 60" storm sewer interceptor to serve the north end of the City.
