Water Storage Tank Coating
The City of Luverne, Minnesota owns and operates a water storage tank that was built in 1945. The tank is a riveted style of construction that was built prior to the full implementation of electric-arc welding. Being less than 20 miles away, DGR Engineering made an initial investigative inspection of the existing coatings to determine an appropriate maintenance strategy. A sample of the exterior paint was removed and analyzed for lead content. Test results showed the paint had a lead concentration that would require abatement.
Abatement of the lead based paint was achieved by requiring a lead stabilizing abrasive additive, a containment shroud with air-impenetrable walls, ceiling, and floors, and safe collection and disposal of the contaminated abrasive media.
In addition to containing the removed lead-based paint, the containment shroud prevented blasting media and newly applied paint from drifting off-site to the adjacent residential housing and busy state highway.

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.
Sutherland, IA
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.
Redwood Falls, MN
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 (SBR)
The City ultimately determined a flow-through style SBR system to be the preferred choice based on the selection criteria and the ability to meet anticipated permit limits.
Orange City, IA
Site Development
Planning started with site plan design for the new facility to offer maximum exposure to traffic on Highway 75.
Rock Rapids, IA
