Detroit Water and Sewerage Department

DWSD Pumping Unit Replacements

Detroit, MI

This project studied the pumping capacity needed for the projected future demand at the Detroit Water and Sewerage Department’s (DWSD) pumping stations. Also with consideration to future demand, this project provided the design of new high and low lift pumps, as well as motors and valves, including all required structural modifications. Benesch was responsible for the heating, ventilating, A/C and plumbing mechanical design; the new electrical service entrance switchgear and pump starter design; and structural design. The design also replaced the steam heating piping and condensate returns, ventilation and A/C in the high and low lift buildings; the plant’s incoming 4.8 KV electrical switchgear; pump drives; electrical power cables; duct banks; structural verification of equipment slabs to handle new pump, motor and transformer loads; and the complete structural redesign of the steel beam supported floors in the low lift station to support the new pump motors and shafts. Because of the implemented changes, DWSD’s facilities are now equipped to handle anticipated rising demand at the pump stations.

Project highlights

  • Design of new pumps, motors, valves for pump stations
  • Anticipate rising demand at pump stations through design
