- Widening US Highway 75
- New Trunk Sanitary sewer
- Design Highway 75 vertical alignment
- Coordination with hospital architect
Sanford Hospitals of Sioux Falls, SD built a new Luverne hospital, which required the completion of several smaller projects.
A sanitary sewer study was performed to review the capacity of the sanitary sewer interceptor that served the north end of Luverne. It was determined the interceptor sewers needed to be upsized to 18” and 15” sewer mains. This required removing and replacing 15 blocks of sanitary sewer main, curb and gutter and asphalt paving. New service lines were installed for homes along the project.
Increased traffic and turning movements off/on to US Highway 75 at the intersection of 131st Street was expected at the north end of Luverne. The Minnesota Department of Transportation required lowering the elevation of the intersection approximately 4’ to improve the site distance. Highway 75 was widened to add turn lanes for the increase hospital traffic. The Rock County Highway Department retained DGR to provide the design, plan preparation and construction staking for the project.
- 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.

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.
