Arc Flash Hazard Study

DGR provided a detailed arc flash hazard study for the electric distribution system for Milford Municipal Utilities. The study provided an easily updateable analysis of the primary distribution system, easy to understand tables for secondary systems, a detailed section by section analysis of the substation, as well as tabular results for the City’s water treatment facilities.

DGR utilizes a unique approach to arc flash studies to control cost as well as provide an easily updateable product to lessen the expense of future arc flash hazard study updates.

Our approach utilizes the latest Windmil® Modeling Software to develop a thorough electrical model of the system, allowing for more accurate analysis and lessening the need for overly cumbersome protective clothing.

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.

Site Development
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.

Wastewater Treatment Facility

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

Wastewater Treatment Facility
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.

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.
