Low Head Dam Design & Survey
DGR performed the topographic survey as well as the design of the low head dam. Construction of the dam involved removing an existing dysfunctional dam and installing sheet piles and rip rap. After construction, the water table rose, benefiting the City’s well fields, and the water quality improved downstream.

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.
