DWSD Electrical Energy Audit

Detroit, MI

The Detroit Water and Sewerage Department (DWSD) needed an Energy Management Plan that provided cost-effective energy savings.

Benesch performed energy audits to determine the existing energy usage and costs for DWSD at their five water treatment plants, 21 booster stations, 11 wastewater pumping stations and wastewater treatment plant.

The team investigated peak load reduction, planned for energy efficient combinations of pumping units and developed an understanding of pump use relative to electric rates. The team also conducted generator use evaluations for peak shaving to reduce utility demand charges; reviewed and appraised energy conservation measures; and developed standard specifications to incorporate energy-efficient equipment.

As a result of these evaluations, Benesch was able to target areas in which the DWSD could implement cost-conscious, energy saving measures that would improve future operations.


Project highlights

  • Energy audits at water treatment plans, booster stations, pumping stations
  • Evaluation to identify energy-saving areas to reduce costs
