Delaware Engineering D.P.C.


About Us

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.
