Engineering

Our engineering services are extensive. Look to us for your transportation, municipal, and land development needs.

Providing the highest level of service means respecting your fiscal, regulatory, and legal obligations. We understand the challenges your public agency faces and we work within those parameters to complete your projects as efficiently and economically as possible.

Infrastructure planning and design
Our team works in the public and private sectors and brings a well-rounded approach to meeting your needs. We believe in frequent, open communication between our team and the public officials we serve.

Wastewater collection systems
We understand the unique challenges of engineering one of the deepest utilities in an area, especially when sanitary sewer systems must be retrofit into developed areas. Our thorough planning upfront leaves few questions down the road.

Water systems
Our experience ranges from distribution systems to booster stations, storage tanks, standpipes, pressure studies, and system analysis. We utilize Water Modeling Software for our pressure studies and system analysis.

Water resources
As infrastructure grows, so does the demand on our water resources. JHA’s team provides design, upgrades, and new construction to manage the changes. In flooding and poor drainage conditions, our emergency response resolves problems fast.
