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.
Rembrandt, IA
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.
