Haestad Methods announced the commercial availability of Hammer, a hydraulic transient modeling solution for meeting the challenges of water hammer and pressure surge projects. Based on technology acquired from the Environmental Hydraulics Group Inc. (EHG), Canada, Hammer is the easiest-to-use transient software on the market, and it allows the vast majority of consultants and engineers to perform hydraulic transient modeling. Hammer’s robust analysis engine and tools provide water utilities with the only user-friendly technology on the market for understanding, detecting, and securing their systems from the threat of transients. Hydraulic transients are the flow and pressure conditions that occur between two very different steady states. Counterintuitive phenomenon can occur during transient events, such as water flowing uphill or flashing into vapor. The effects of such events on a water distribution system can lead to unreliable water quality and costly repair bills. Hammer supports engineers in their efforts to reduce the risk of system failure, minimize leakage, improve operating strategies and enhance water quality, all of which help ensure public safety and the longevity of the infrastructure.
