- Raised the level of the water table
- Improved water quality
- Removed existing dysfunctional dam
- Project coordination with the Iowa DNR, general contractor, and subcontractor.
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.
- Electrical Power
DGR engineers helped L&O Power Cooperative improve communications on its electric transmission system using existing transmission lines, fiber and underground fiber line.

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.
