GIS Mapping

DGR developed an electric GIS mapping system for the City of Madison, South Dakota. The project entailed obtaining high resolution, geo-referenced aerial imagery to serve as a base background to the system.

With the help of City personnel all existing primary distribution lines were identified and located and all existing overhead distribution poles and streetlights were given GPS locations.

Conductors were colored/dashed depending upon phase and number of phases. Conductor sizes and correlating circuits were input into the line sections features.

Meters, transformers, and switches were included along with detailed information such as switch style, meter number, transformer size, and age.

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.

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.

Wastewater Treatment Facility

MBBR technology was chosen based on cost, operational flexibility and most importantly, limited land availability.

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.

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.

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.
