Our History
Founded in 1997, Keystone Engineering Group is a multidisciplinary engineering and automation firm delivering practical, innovative solutions for infrastructure and industrial clients throughout the Mid-Atlantic region. With a growing team of 80 professionals across five offices in Pennsylvania, New Jersey, and Delaware, we provide integrated engineering design, controls integration, and technical consulting services that help communities and organizations operate more efficiently, safely, and sustainably.
Working With Us
Collaborating with Keystone means receiving a custom solution tailored to your unique operational, regulatory, and performance needs — not a one-size-fits-all approach. Our intellectual capital, technical depth, and real-world experience distinguish us from traditional engineering firms. We bring together civil, mechanical, electrical, and environmental engineering with advanced automation and SCADA expertise to create cohesive, forward-thinking systems.
What sets Keystone apart is our ability to seamlessly align engineering design and automation under one roof. By integrating our Engineering and Automation teams from concept through commissioning, we reduce risk, improve constructability, enhance operational performance, and simplify long-term maintenance for our clients. Our work spans water and wastewater treatment facilities, pumping stations, municipal infrastructure, and industrial systems — delivering solutions that are reliable, compliant, and built for the future.
