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.

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.
