Haestad Methods Delivers Proven Transient Modeling Software with Hammer(TM)



WATERBURY, CT, USA - August, 2003 - Haestad Methods today announced the commercial availability of Hammer(TM), a revolutionary 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 will allow the vast majority of consultants and engineers to perform hydraulic transient modeling.

"This acquisition and the ongoing collaboration with EHG further demonstrates our ability to rapidly deliver critical technology to the water resources community," said John Haestad, President and CEO of Haestad Methods. "Hammer's robust analysis engine and sophisticated visualization 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.

For example, a low-pressure transient event, arising from a power failure or pipe break, can cause the intrusion of contaminated groundwater. In addition, high-pressure surges caused by the rapid closure of a valve can result in pressure waves whose magnitude is several times greater than those calculated by steady state analyses. By alerting water utilities of extreme transient pressures, 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.

Hammer technology has been used for over 15 years and on over 150 consulting projects. Anthony Parente commented on how the Region of Peel, Canada, benefited from Hammer, "We needed to protect all pump stations and main feedermains from water hammer damage as well as the thousands of water distribution pipes in connected pressure zones. The results of the Hammer analysis led to a solid surge control strategy to protect the water system." Other organizations that have profited from Hammer in their critical infrastructure development projects include Newmont Gold, Nevada; City of Toronto's Humber Wastewater Treatment Plant; L.B. Pearson International Airport, Toronto; and Barrick Gold's Pascua Lama Mine Complex, Argentina.
