Key Features:

  • 10 MW Diesel Generation Plant
  • Five 2,000 kW, 13.8 kV generator sets
  • Combined generation plant and substation project

Key Experience:

  • The Responsibility and involvement in all phases of the project, from project feasibility to final testing and checkout.
  • Designing both a generation plant and a substation into one project, in order that certain facilities could be shared and construction efficiencies could be realized.
  • Design of a fully automated generation control system and interface with the City’s SCADA system.

Generating Plant

The project included full services for the construction of a new generation plant and substation.  Cost savings for the Owner were achieved by combining a substation project and a generation plant project, in order that shared facilities could be constructed.

DGR services for this project included project feasibility, environmental permitting, engineering design, material procurement, and construction administration.

Sanitary Sewer Rehabilitation

The project was bid and came in under budget. Manhole lids were raised to provide better access in some areas, and rehabilitation of the sewer system was completed to give another 50 years of life to the City’s much-needed infrastructure.

Floodplain Analysis

DGR employed a Geographic Information System (GIS) in conjunction with the U.S. Army Corps of Engineers to first determine the 100-year flood elevations and delineate the floodway boundaries.
