MWH Soft Introduces H2OMAP SWMM Suite


New State-of-the-Art Extensions Herald Significant Leaps in Urban Drainage Systems Modeling

Broomfield, Colorado USA, March 15, 2006 - Underscoring its ongoing commitment to delivering pioneering technology that raises the bar for water and wastewater modeling, leading global environmental and water resources applications software provider MWH Soft today announced the worldwide availability of H2OMAP SWMM Suite. The comprehensive release expands users’ power and ease of use in managing sanitary, storm and combined sewer systems, while state-of-the-art DWF Allocator and Calibrator extensions enable wastewater engineers and GIS professionals to slash modeling time and costs, minimize modeling errors, and significantly increase productivity.

Supporting native GIS data as well as the USEPA’s industry-standard (and FEMA-approved) Storm Water Management Model (SWMM5), H2OMAP SWMM Suite integrates the needs of both GIS and wastewater engineering professionals in one complete, affordable package. Important cutting-edge features and a wide array of enhancements greatly simplify and accelerate urban drainage network engineering, helping wastewater engineers develop better designs and operational improvements faster and more efficiently, helping to shape the future of this critical sector.

The new Suite’s most significant strengths include a DWF Allocator module that delivers unprecedented speed, accuracy, and flexibility in calculating, distributing, and managing dry weather flows in sewer network models. DWF Allocator automatically and reliably computes, tracks and assigns dry weather flows generated by various customer categories, based on land use and development characteristics, population, sanitary service areas, parcel data, or meter data - considering existing sewer system conditions and various planning horizons.

Another highlight is the Calibrator module, which makes it possible to reliably and swiftly calibrate very large and complex urban rainfall-runoff models, supporting better analysis and design. Using advanced genetic algorithms optimization technology, Calibrator automatically adjusts sewer and drainage system parameters to accurately match collected flow, depth, and velocity measurements for both single event and long term continuous dynamic simulations. These parameters can include any combination of subcatchment, soil, aquifer, RDII, and conduit properties.

“H2OMAP SWMM Suite was developed with end users in mind, and nearly all its innovations and enhancements were direct results of user specific requests and suggestions,” said Trent Schade, PE, Senior Client Service Manager and National Stormwater Technology Leader for MWH Soft. “We spend hundreds of hours with our customers to learn how we can improve our products to help them achieve their engineering goals. Our new H2OMAP SWMM Suite redefines the boundaries of innovation in the wastewater modeling industry by providing new, powerful tools that make urban drainage modeling easy, fast, and fun.”

“Speed, ease of use, flexibility, and power are the words that best describe H2OMAP SWMM Suite,” said Paul F. Boulos, Ph.D, President and COO of MWH Soft. “Users will be amazed at how efficiently the new suite extensions can automate common, tedious modeling tasks, enabling them to quickly generate the credible models they need to maximize system performance at minimum capital investment. We will continue to develop vital new technologies that improve the modeling process, so that someday, developing a drainage model will be as easy and fast as turning on a light.”
