Marshall Municipal Utilities
- 8 kV underground distribution system
- Multi-year, multi-phase project
- Increased system reliability through additional circuits and reduced exposure
- 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.
- Electrical Power
DGR engineers helped L&O Power Cooperative improve communications on its electric transmission system using existing transmission lines, fiber and underground fiber line.

Treatment Plant & Well Exploration
DGR Engineering worked closely with OCRWS to design a new Water Treatment Plant to target iron and manganese removal from a shallow groundwater source near the site.
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.

Street & Utility Improvements
Morningside Avenue was reconstructed totaling approximately 1,300 linear feet. The project included new sanitary sewer, water main, storm sewer, fiber conduits, decorative street lighting, and 9-inch concrete paving with colored concrete sidewalks.
Sioux City, IA
Wastewater Treatment Facility
The new plant, rated for 5.3 million gallons per day (MGD) peak day, doubles the capacity of its predecessor.
Planning started with site plan design for the new facility to offer maximum exposure to traffic on Highway 75.
