To understand existing conditions and evaluate opportunities to upgrade the facility, D&K supported Patriot Hydro by providing an evaluation and designing upgrades of the 1.6MW Hooksett Hydroelectric Project. The team assessed existing conditions, including civil-structural, equipment, hydrologic and hydraulic, and natural resources. D&K also completed an electrical generation study that identified ways to optimize the…
The Town of Chester needed to address hydraulic capacity and condition issues associated with a 165-ft-long by 15.5-ft-high earthen dam with a concrete spillway impounding a small recreation pond. The site was constrained and funding for the project was limited. As Town Engineer, D&K evaluated the dam, watershed, and natural resources, developed alternatives, and provided…
The Town of Swanzey needed to improve the stability and safety of an earthen dam serving an 80-acre pond. The pond supports recreation and enhances the value of the homes located along its shoreline. The dam had seepage issues and did not meet current dam safety standards. Using articulated concrete blocks as overtopping protection, DuBois…

As the result of a fire that partially engulfed a 45-room, wood-framed hotel building, the Bluenose Inn required substantial repairs. D&K supported the owner and the architect by providing fast-tracked survey, site design, permitting assistance, and coordination with municipal officials, as well as mechanical and electrical engineering for 21 suites and parking for 88 vehicles….
The US Fish and Wildlife Service had to replace the failing water supply sediment filter serving the hatchery fish rearing tanks. D&K designed a new filtration system and provided engineering guidance to allow the legacy system to remain online and serve the typical 22-MGD flows during the construction phase. Our team also optimized the system…
Previously, the farm leachate collection system for the haylage bunker silos drained over a paved area to a storage tank during low flows and overflowed through a bar screen to a municipal catch basin on a roadway during high flows. The project replaced the bunker silos with a roofed bunker silo area, and installed a…
Illig Dairy Farm needed to replace an undersized earthen manure pit with a new concrete waste storage facility. D&K advanced the design and engineering, prepared plans and specifications, and observed the construction of a structure with an access ramp and a manure transfer channel.
