Hydraulic transients, or pressure surges, are created when sudden changes in flow rates occur in pumping and pipeline systems. The pressures created may be high enough to damage or even cause catastrophic failure of pipelines. Specialized hydraulic transient analysis provides the basis for designing surge control measures to protect important infrastructure.

NHC provides hydraulic transient analysis and design recommendations for control of adverse pressure surges. These services apply to analysis and design of a wide variety of facilities including water supply, wastewater, and stormwater pump stations; water distribution networks; well fields; treatment plants; hydroelectric and thermal power plants; fueling and fire protection systems; and oil and gas pipelines.
