Building Pathways for Connection

Smart and successful infrastructure design ties communities together, balancing human needs with environmental stewardship. At EHRA Engineering, we believe achieving this balance is essential to the shared space in which we work and live. Our holistic and collaborative approach offers solutions that address financial, social and environmental concerns, from concept through construction. Through changes in technology, codes, standards and best practices, we adapt to offer complete solutions for everything from roads, bridges and trails to water and wastewater treatment and conveyance.

We use value engineering to avoid overdesign of systems, yielding greater results in technical, economic, social and ecological concerns. Using cutting-edge computer software and hardware technology, EHRA formulates customized programs for our clients in the development of efficient and sustainable systems for transportation, treatment facilities, pumps and piping networks and storm detention and conveyance. Our approach is to work collaboratively with public and private partners to realize the best possible outcome.
