Waterhammer studies

Fluids are often transported under pressure. Think of drinking water networks, certain industrial process pipes and sewage pumping stations. If these systems are not well designed this may lead to adverse consequences for the infrastructure. One of the possible consequences is water hammer, which occurs when a sudden pressure change caused by the activation or deactivation of pumps creates a pressure wave through the pressure pipeline, which may lead to high overpressure or underpressure in the pipeline network. Such pressure may be so strong that the infrastructure explodes or gets damaged severely due to cavitation.

HydroScan in cooperation with Deltares

HydroScan is one of the few consultancy companies that has the right tools to perform a water hammer analysis. For this purpose we cooperate with Deltares, who provide us with the Wanda water hammer software. During a focused water hammer analysis, we define which safeties are required.

The HydroScan approach

Our step-by-step approach:

Building a water hammer model that simulates the dynamic flow of pressure waves based on available plans;
Performing calculations for and simulating specific scenarios, such as sudden power failure;
Determining if additional water hammer safeties are required based on the results of the simulations, such as aerators or air chambers, or adjusted pump control;
This additional infrastructure is then designed so that water hammer effects remain within acceptable limits.
