Client:

Marshall Municipal Utilities

Key Features:

  • 8 kV underground distribution system
  • Multi-year, multi-phase project
  • Increased system reliability through additional circuits and reduced exposure

Key Experience:

  • Responsibility and involvement in all phases of the project, from the initial study work to design and bidding and observation of the final construction.
  • Coordination with multiple entities including City, County, and State authorities and other utilities.
  • Addition of padmount capacitor banks to the system to replace overhead capacitor banks that were removed.

Electrical Distribution Conversion

The project included full services for the conversion of the utility’s distribution circuitry from overhead to underground.  The conversion was completed in several project phases as part of a multi-year process.  The project also included the construction of several new circuits that were integrated to new substations being built in the same timeframe.  DGR services for the project included the reliability study work, preliminary planning, permitting, engineering design, material procurement assistance, construction administration, and resident project observation.

Site Development

DGR Engineering (DGR) worked with the City and the project architect for all aspects of the project including topographic survey, site design, construction survey, construction observation and administration.

Sioux City, Iowa

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.

Wastewater Treatment Facility

MBBR technology was chosen based on cost, operational flexibility and most importantly, limited land availability.

Sanborn, IA

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.

Distribution Conversion

Due to concerns with the age and condition of the structures, along with safety clearances to energized equipment and conductors, a project was undertaken to replace the old infrastructure with new underground lines and associated padmount equipment.
