Redwood Falls, MN
- Replacement of old overhead infrastructure with new underground infrastructure,
to increase reliability and improve aesthetics
- Eliminated public safety concern of old transformer platform structures
- Responsibility and involvement throughout the project, from initial planning and design
to construction administration and contract closeout
- Development of a multi-year plan for staged construction of the improvements
- Coordination with private communications utilities including joint use of excavations
Electric distribution lines in the downtown alleys of Redwood Falls, MN consisted of large overhead structures which included transformers mounted on platforms. 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. In addition, these improvements would improve the overall attractiveness of the area.
The 11 block project was split into two phases to allow for completion over two construction seasons. In addition to burying the overhead primary circuitry, most of the overhead secondary circuitry associated with the conversion area was converted to underground.
DGR Engineering developed a full design for the new underground circuitry, including equipment and cable sizing, equipment locations, line routes, and material lists. Bidding and contract documents for construction of the improvements were developed, which included detailed design drawings, staking sheets, and technical specifications. The completed project resulted in a safer and more aesthetically pleasing downtown area that was also up to current standards for infrastructure and reliability.
- Electrical Power
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.

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.
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.
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.
