The Addison Town Hall and Addison Community Baptist Church needed a centralized wastewater system to reestablish use of the historic Town Hall building, which sat vacant for nearly a decade. The structure required significant renovation, and its marginal (mostly clay) soils and a high water table made a conventional on-site wastewater system infeasible. At the…
The city completed the design of improvements to the existing wastewater pump station. Through that process, it became evident that the existing system had reached the end of its operating life, and selected components should be replaced rather than upgraded to provide increased reliability, energy efficiency, safety, and compatibility with other city pump stations. D&K…
Orwell’s wastewater treatment facility includes an aerated lagoon facility that provides secondary treatment and chlorine disinfection of wastewater. The facility’s aging lagoon aeration system was a submerged lateral system that had become inadequate and inefficient. D&K provided design, bid, construction management, and startup assistance services to upgrade the lagoon aeration system to meet current standards….
The 40-year-old Northfield Wastewater Treatment Facility (WWTF) required a comprehensive upgrade of the facility and process conversion from Trickling Filter (TF) to Sequencing Batch Reactor (SBR) to comply with stringent phosphorous limitations. The site was constrained by the railroad and the Dog River, requiring geotechnical measures to protect rails. D&K conducted all professional engineering services…
During the surge of Tropical Storm Irene, flows at the town’s wastewater treatment facility decreased by 60%. It was determined that a double-barrel sewer siphon, consisting of an inlet and outlet structure, was destroyed by the storm when the Third Branch of the White River migrated 90 feet to the northeast. D&K provided design and…
The Glencliff Home is an off-the-grid assisted living facility whose primary purpose is to provide adults with mental health care. The campus includes residential, care, office, and maintenance spaces and uses a combination of renewable energy systems, including a hydroelectric facility, as well as fossil fuels to supply power and heat. For many years, D&K…
The city wished to evaluate and determine cost-effective measures to reduce on-site natural gas use, receiving partial funding through the VGS Energy Efficiency program. D&K’s project team conducted a site visit to obtain detailed information on existing natural gas use-related processes, HVAC and building envelope materials, equipment, and systems. We reviewed historical natural gas use…
D&K provided civil/site engineering and construction phase services for site development associated with the construction of a new student center. Services included design for access and parking, including pavement markings and signage, walkways and paths, fencing, drainage, stormwater management, water system, and gravity wastewater system. The stormwater management system was designed with subsurface retention chambers,…
The Gray Farm needed a new waste storage facility and leachate collection system. D&K visited the site and conducted field survey and mapping, soil investigations, preliminary engineering, final design, and construction phase services while following the requirements of the NRCS EQIP program.
