Water supply and wastewater treatment are the engineering sciences on which DuBois & King was founded. Since 1962, D&K has planned, designed, and observed the construction for wastewater treatment and collection systems. We design municipal-scale facilities, as well as on-site treatment and disposal for communities, housing, institutions, and industrial facilities. D&K teams design wastewater pump…
The goal of the Crescent Connector project was to provide a bypass of the congested Five Corners intersection for south-to-east travelers. The project included complete streets enhancements, parking, an 850-ft segment of new roadway, and 500 ft of roadway enhancement around the east side of Five Corners. D&K served as the lead consultant, designing the…
The City of Burlington required a 20-year engineering evaluation of its wastewater treatment plants, collection system, and pump stations; the development of a 10-year capital plan; and consultant services related to wastewater revenue bonds. Satisfying the bond requirements required D&K to provide recommendations regarding (1) operation and maintenance, (2) ways to improve the operation of…
PurposeEnergy, a nationwide renewable energy producer, sought to develop an anaerobic digester and food process treatment facility near Middlebury’s wastewater treatment facility (WWTF) in the heart of the town’s industrial district. The project accomplishes two significant goals: reduce loading from food-process waste to the municipal WWTF and maximize the reuse of waste products through a…
The 40-year-old wastewater treatment facility, originally designed for a 20-year service life, was past due for a total treatment process change and facility upgrade. The project objectives included: utilize a state-of-the-art treatment process, design capacity for nitrogen removal, consider operational efficiencies and long-term operating costs, address issues with the location in a floodplain, and develop…
Waitsfield has long served as a thriving cultural center of the Mad River Valley and includes the village districts of Irasville and Waitsfield Village. The immediate VT 100 corridor primarily comprises shops, gathering places, schools, neighborhoods, and some light industry, but is largely served by septic systems, many of which are in the floodplain and/or…
The Great Streets BTV planning document, coauthored by D&K, represented a holistic effort to make Burlington’s downtown core more appealing for users of all modes of transportation and to enhance the area’s ability to engage its natural and cultural assets. D&K’s approach to the project incorporated the first segments of roadway designed and constructed to the Great Streets standards….
Craig Brook NFH is one of over 70 federal hatcheries in the country operated by the U.S. Fish and Wildlife Service. Opened in 1871, it ranks as the oldest salmon hatchery in the country and was established for the production of Atlantic Salmon to supplement natural propagation and augment the annual runs along the Atlantic…
Manufactured housing communities in Vermont provide practical housing solutions; however, some of these communities are disproportionately affected by environmental issues. The Vermont Department of Environmental Conservation sought consultants to provide Preliminary Engineering Reports (PERs) and design solutions that responded to the specific challenges faced by MHCs and a backlog of failing wastewater, potable water, and…
