Sanitary sewer
In the fall of 2016, the City selected DGR to reconstruct water mains, sanitary and storm sewer and pavement for their 2017 infrastructure project. DGR assisted the City in managing all phases of reconstruction work within the existing community to limit the inconvenience and provide long-term solutions for these project segments.
DGR performed the boundary and topographic surveying as well as the site design of school building addition as a subconsultant of Architecture, Inc.
The school facility addition design included storm sewer upgrades, pedestrian facilities to multiple building levels, enhanced and expanded parking, as well as access road design to facilitate the future campus growth.
The design also included realigning water main and sanitary sewer main beneath the building link to avoid proposed footings as well as a rainfall harvesting system to collect and recycle rainwater from the building roofs.
DGR Engineering worked alongside the City of Sioux Center and Sioux Center Land Development to help secure Iowa DOT RISE funding. Following a topographical survey and preliminary design, DGR performed the boundary survey which included transferring new road right-of-way to the Iowa DOT.
The design and construction included evaluating the current and future growth trends of this portion of the City, such that sanitary sewer and water distribution system could be adequately sized to serve this development and future growth. The storm sewer design not only included the sizing of storm sewer pipe, intakes and stormwater detention basins, but also addressed an existing, undersized culvert beneath Highway 75. A phased traffic control plan was necessary to facilitate 2-way traffic on Highway 75 while a new culvert was being installed. DGR also worked with the businesses who relocated their operation along the highway frontage during the planning, design and construction phases to help the project best fit the end-user needs.

In the fall of 2008, the City selected DGR to reconstruct water mains, sanitary and storm sewer and the highway pavement on Jefferson Street and TH 68. DGR assisted the City in obtaining funding for approximately 70% of the project costs via grants, state aid and county participation. The project utilized funding from the above referenced sources, as well as the City. DGR provided full time construction observation and administration to aid the City and record keeping and testing required by these agencies for reimbursement.
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.
