Water Treatment Facility Engineering

DP-NXA leadership and team members have extensive experience working with large and small municipal facilities as well as industrial operations.  We make sure that we adhere strictly to all security and safety mandates for the owner’s sites.  Our team of professionals take the time to walk down all the project locations to ensure that we understand the existing conditions as well as the constraints that might be encountered by a construction contractor. We develop designs with an understanding of what it takes to maintain and operate the facility.  We consult with the owners and general contractors to make sure that the design solution we develop can be constructed with the minimum of impact to the owner’s ongoing operations.  We collaborate with the Process Engineers to ensure that the systems/facilities being designed meet the requirements of the treatment plant.
