Delaware Engineering, D.P.C. is different from other professional engineering firms. Our deep respect for our clients, community, and colleagues sets us apart.
Our clients are predominantly municipal entities with selected industry in our portfolio as well. We understand that municipal leaders come to government from all walks of life and bring unique perspectives, knowledge and experience that are to be respected and engaged in the process of governing. The functions of government are complex and it is our role to provide facts and guidance to municipal decision-makers to ensure that the best interests of the public are achieved. With respect to industry, we are keenly aware that infrastructure and regulatory compliance are non-core functions that in some cases distract from operating a successful, profitable business. Our role is to handle non-core infrastructure and regulatory functions so that business leaders can focus on core functions.
Our community is as broad as the locations in which we work. From our offices in Albany and Oneonta, our geography spans from New York’s Capital District throughout the upper and lower Hudson River Valley through the Adirondack and North County Region to the Metropolitan Suburban Region north of New York City through the Catskill Region to the State’s Southern Tier. Wherever we are engaged with municipalities or industry, we are engaged with community. We respect the unique character and nature of each community in developing customized solutions to water, wastewater, stormwater, municipal buildings, special projects and economic development challenges. Because we take the time to get to know each community personally, we treat each person and each project with a commitment and passion as though it is our own home town.
Our colleagues are the engine that drives our business. Our professional and technical staff of more than 60 engineers, scientists, planners and technicians are each responsible for the well-being of our clients, our communities, and each other. By encouraging personal connection and responsibility between our staff and their project work, clients benefit from the sincere dedication of our staff to a project’s success. Since the founding of the company in New York’s Delaware River Watershed in 1987, our colleagues continue to be driven by an intense desire to improve the world through everyday successes.
Delaware Engineering, D.P.C. is different from other professional engineering firms in our achievements in supporting communities and industry through access to grants and low cost financing and our community service contributions which we see as a small way to pay our accomplishments forward.
We welcome opportunities to explore new relationships with clients, communities, and colleagues.
Concentrations of development in cities, villages and hamlets within towns as well as industrial processes result in volumes of wastewater that can pose a threat to the environment and public health if untreated. The professionals at Delaware Engineering, D.P.C. specialize in the characterization, collection, treatment and discharge of municipal and commercial/industrial wastewater. Achieving stringent discharge standards and targeting wastewater solutions to meet economic as well as environmental objectives through planning, permitting, design, bid assistance, construction oversight and start-up/operations support are the hallmarks of Delaware Engineering’s practice. Delaware Engineering’s expertise in securing grants and low cost financing for wastewater projects through federal, state and regional entities to support public health and economic development initiatives is unmatched.
Delaware Engineering prepared a Facility Plan for Orange County Sewer District No. 1 that reviews alternatives to address sewer capacity and longevity issues. The Facility Plan provides a comprehensive review of the Harriman WWTP, a facility with aging infrastructure that uses numerous technologies to treat wastewater both from District 1 and from adjacent Orange County communities. In addition to analyzing improvements that would extend Harriman’s useful life without increasing capacity, Delaware also evaluated the costs and benefits of a Regional Approach that would expand capacity to accommodate economic development.
Founded in 2005, Chobani has realized remarkable success within the U.S. dairy product industry, growing to a more than $1.5 billion company that has had a positive impact on both the dairy industry and on employment in Upstate New York. As yogurt sales skyrocketed for the company, so did its wastewater flows. Chobani contracted with Delaware Engineering to plan, permit, design, and supervise the construction and start-up of a new 900,000 GPD membrane bioreactor (MBR) wastewater treatment plant. The new WWTP was constructed while the existing 100,000 GPD aerobic lagoon system remained in service. Delaware designed and constructed the plant in a way that minimized initial capital outlays and ensured that subsequent expansions will be cost-effective.
This fast-tracked project was constructed in the winter of 2011 on a parallel track with NYSDEC review and approvals. Delaware, Chobani staff, on-site contractors and the MBR system supplier worked closely to keep project design and construction on track. New WWTP components to treat the high-strength wastewater included a new aerated equalization tank upstream of the existing dissolved air flotation process, MBR tanks and components, in-line UV disinfection, a 1500 KW diesel generator and a new 2 story masonry control building. The new WWTP went online in 2012, with subsequent closure and removal of the existing lagoon, clarifier and WWTP building. The WWTP is meeting all SPDES permit limits, including new Chesapeake Bay nitrogen and phosphorous limits.
in 2012, Delaware Engineering provided planning, permitting, design and construction supervision services for necessary repairs and upgrades to the Village of Athens’ wastewater treatment plant. Upgrades included a new headworks building with fine screening and grit removal, and improvements to the aeration system, secondary clarifier, disinfection system and sludge handling facilities. Due to the site’s location in the Hudson River flood zone, Delaware’s design incorporated flood-resistance features; the design was tested during Superstorm Sandy later that year and performed well.
Delaware also assisted the Village in procuring $4.6 million in CWSRF funding for the upgrades, and for inflow and infiltration work.
How to treat wastewater resulting from brewing and bottling activities depends on the volume of water required, and the makeup of the wastewater. There are various organic components present in brewery waste, like sugars, soluble starch, volatile fatty acids, and ethanol. These biodegradable organic materials also consist of various solids like spent grains and waste yeasts. The brewing process generates a high-strength wastewater with a high concentration of bio-chemical oxygen demand (BOD) from the carbohydrates and protein used in brewing beer.
For this smaller brewery application in Hoosick Falls, Delaware designed an aerobic treatment approach to provide increased flexibility for the high organic loadings. Aerobic treatment has less potential to produce offensive odors than anaerobic processes. The wastewater treatment system selected for Brown’s Brewing Company is comprised of a fine screen rotary drum, aerated equalization basin (EQ), anoxic tank, pre-aeration basin, and submerged membrane bio-reactor (MBR). The MBR system was chosen due to its flexibility in treating varying organic wastes.
Delaware Engineering assisted the Village of Canajoharie by implementing a WWTP efficiency project to address the aging components of the existing system as well as reduce operating costs and demands.
The wastewater improvements included a new influent screen and grit removal system, conversion of existing oxidation ditches into a fine bubble aeration system and an aerobic digester, disinfection system upgrades, rehabilitation of the belt filter sludge press, new computerized operational controls, and architectural upgrades to increase the facility’s energy efficiency. Improvements also include a new emergency generator rated at 500KW, 480 Volt, 3-phase.
Delaware also assisted the Village with funding procurement. The WWTP efficiency project was funded by Village funds, a CBDG $600,000 Grant, NYSESD-CCAP $650,000 Grant, and CWSRF $750,000 Grant and $1MM 0% Loan. Construction started in the late winter of 2014 and was completed in the spring of 2015.
Delaware Engineering assisted the City of Hudson with Combined Sewer Overflow compliance and upgrades to aging plant facilities. The project involved the planning, permitting, design and construction of a new influent pump station, headworks and wastewater disinfection system capable of handling 17 MGD in accordance with the City’s Long Term Control Plan. The project also included upgrades to the 6.0 MGD aeration system, primary and secondary clarifiers, replacement of the sludge processing equipment, sodium hypochlorite storage and feed systems, and upgrades to a 5 MGD off-site pumping station. The project was financed by the American Recovery and Reinvestment Act and was completed in 2011.
The Kent Manor Sewer Corporation contracted with Delaware Engineering/ Milnes Companies in a design-build contract to design and construct a membrane bioreactor (MBR) wastewater treatment plant. This facility treats residential sewage from the Town of Kent and a proposed residential subdivision. This facility is located within the NYC Watershed and meets all requirements for microfiltration. Additionally, the facility meets a very stringent total phosphorus limit of 0.05 mg/L in compliance with the project’s phosphorus offset pilot program. The facility includes flow equalization, fine screening, membrane bioreactor, chemical addition for nutrient removal, and chlorine disinfection.
