Hydraulics is concerned with the flow and conveyance of fluids, principally water, and sewage. One feature of hydraulic systems is the extensive use of gravity as the motivating force in the movement of the fluids.

Hydraulic engineering is the application of fluid mechanics principles to problems dealing with the collection, storage, control, transport, regulation, measurement, and use of fluids. HBP’s engineers develop conceptual designs through to detailed design for each of the sub systems listed below:
