Mainline Distribution Circuits
The project included the construction of three new mainline 13.8 kV circuits on the City’s distribution system to increase capacity and reliability. The circuits were built in underground fashion; two extending from the City’s substation near the airport to the downtown area, and one extending from the City’s substation near the airport to the event center. DGR services for this project included the initial study work, project development, engineering design, permitting, construction administration, and resident construction observation.

Treatment Plant & Well Exploration
DGR Engineering worked closely with OCRWS to design a new Water Treatment Plant to target iron and manganese removal from a shallow groundwater source near the site.
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.
