Bartlett Street Pump Station
Portland, Connecticut

THE CHALLENGE: Originally constructed in 1950, the Bartlett Street Pump Station served a high service zone in combination with a one million gallon storage tank. The controls for the pump station were outdated, operating space was cramped and minimal, the building envelope was in need of renovation, and driven by the frequency of main breaks in the pressure zone, controls for hydraulic surge had to be incorporated. THE SOLUTION: In consultation with the staff of the Portland Water Division, Nathan L. Jacobson & Associates, Inc. made a study of alternatives, including renovating and refurbishing the existing pump station and constructing a new pump station. Refurbishing the existing pump station would have required constructing temporary pumping facilities, making construction of a new pump station a more expensive, but competitive alternative. In preliminary studies, Nathan L. Jacobson & Associates, Inc. provided opinions of probable construction costs for the alternatives. With preliminary study information, the Portland Water Division decided that construction of a new pump station would best serve their current and future needs and obtained Commission approvals for funding the project.

Construction contract documents were prepared for a pump station housing two 300 gpm vertical multistage pumps with pump control valves, surge relief valve, and flow metering. Pump controls were integrated with a supervisory control and data acquisition system and included new level sensing equipment and security improvements at the High Street storage tank. The building envelope selected was masonry cavity wall construction with a wood frame roof. A propane gas fired heater with underground fuel storage provides efficient environment control in concert with a ventilation system. The construction contract documents also included demolition of the existing pump station after completion of its replacement. Nathan L. Jacobson & Associates, Inc. prepared the contract documents and provided construction administration and start-up services. After 7 months of construction, the project was completed in 2002 at a cost of approximately $300,000.
