At DGR Engineering, we build the foundation for every day. From roads and power lines to where parks and water intersect your life, we make it all work, and we’ve been doing it for more than 65 years. Our projects in civil engineering, water systems, electrical distribution and surveying can be
found all across the Midwest.
We build projects that both our clients and our employees can be proud of, because we live where we work. We have offices in Rock Rapids, Sioux City, and Ankeny, IA as well as Sioux Falls, SD and we share that foundation with our clients.
As one of the top engineering firms in the country, DGR received notice that it was selected as a repeat honoree by PSMJ Resources, Inc. for inclusion in its 2019 “Circle of Excellence”. DGR has earned this honor every year since 2014.
Water Source Development
DGR and Red Rock Rural Water System teamed up with POET to perform a program of exploratory drilling, test pumping and well field development. Designed three production wells capable of supplying 1.4 MGD to the ethanol plant and 9 miles of 10” diameter raw water main.
This pair of projects encompassed eight downtown alley blocks over two construction contracts in consecutive years.
The North Core Pipeline project consisted of approximately 70 miles of pipeline from near Ft. Pierre to Philip, four ground storage reservoirs, and four pump stations.
Wastewater Treatment Facility (SBR)
The new plant, rated for 5.3 million gallons per day (MGD) peak day, doubles the capacity of its predecessor.
