MWH Soft Unveils H2OMAP SWMM Designer


State-of-the-Art Extension Delivers Unsurpassed Optimization Capabilities for Eliminating Unwanted Sewer Overflows at Maximum Cost Savings

Broomfield, Colorado USA, April 26, 2006 - Underscoring its ongoing commitment to delivering pioneering technology to the wastewater industry, MWH Soft, a leading global provider of environmental and water resources applications software, today announced the worldwide release of H2OMAP SWMM Designer. The new extension is fully integrated with H2OMAP SWMM Suite, meaning that for the first time, engineers can quickly and accurately simulate, analyze, design, and optimize large and complex sanitary, storm and combined sewer systems in a single, seamless operation. The sophisticated tool demystifies the complex science of urban drainage modeling, making it an easy and enjoyable task.

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. Distinguished by a compelling combination of cutting-edge GIS functionality and hallmark hydraulic, hydrologic and water quality simulation capabilities, H2OMAP SWMM Suite offers a powerful and comprehensive solution that greatly simplifies and accelerates urban drainage systems modeling, enabling engineers to develop better designs, rehabilitation and improvement alternatives faster and more cost-effectively.

The new Designer extension leverages the power of advanced Genetic Algorithms optimization technology to aid in preventing sewer overflows - a leading cause of water pollution in the nation’s lakes, streams and inland bays. The untreated sewage in these overflows contains microbial pathogens, suspended solids, toxics, nutrients, trash, and other impurities that deplete dissolved oxygen and can contaminate our waters, causing serious water quality problems and threatening drinking water supplies, fish and shellfish. This waste can also back up into basements, causing property damage and creating threats to public health.

H2OMAP SWMM Designer automatically selects the most cost-effective solution to flooding and pollution management, using a combination of pipe slope and size, storage, pumping and new piping strategies to eliminate unwanted sewer overflows and achieve targeted system performance requirements. Performance criteria include maximum allowable depth-to-diameter ratio, minimum and maximum pipe velocities, and maximum head loss for force mains. The software gives engineers the ultimate tool for producing the best design and improvement alternatives with minimum effort and maximum cost savings. Its comprehensive capabilities will greatly assist wastewater utilities in planning and designing reliable systems and optimizing their capital improvement programs - leading to healthier communities, cleaner beaches, and fish and shellfish that are safer to eat.

The breadth and depth of MWH Soft’s product line is unmatched in the industry, providing customers the unique ability to manage, operate and maintain their hydraulic infrastructure supported by the most advanced network modeling and optimization solutions on the market. Other H2OMAP SWMM Suite modules include:

Dry Weather Flow Allocator: a module that automatically 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.

Calibrator: a Genetic Algorithm-based module that automatically adjusts sewer and drainage system parameters to match collected flow, depth, and velocity measurements for both single event and long term continuous dynamic simulations. Parameters can include any combination of subcatchment, soil, aquifer, RDII, and conduit properties.

“Simply put, Designer makes our H2OMAP SWMM Suite urban drainage modeling solution the best choice for any utility and engineering organization looking to optimize sewer systems design and operation at maximum cost savings,” said J. Erick Heath, PE, Vice President of Sales and Client Relations for MWH Soft. “After listening to our customers, we’ve delivered a broad set of new, optimal design capabilities, and will continue to make sewer systems modeling and management easier and more approachable to the wastewater industry. This critical solution will have an immediate impact on our customers’ productivity and performance, and we’re very pleased to bring it to the market.”

“Our customers are transforming the world around us, from the water we drink and the beaches where we swim to the communities in which we live,” said Paul F. Boulos, Ph.D, President and COO of MWH Soft. “Our software helps professionals in the water and wastewater industries simulate reality, giving them the capacity to plan, build, operate, protect and maintain their infrastructures more effectively and reliably than ever before. The new H2OMAP SWMM Suite automates tedious modeling steps, enabling users to quickly and easily perform the highly sophisticated modeling needed to optimize stormwater runoff management plans and control or eliminate sanitary sewer overflows (SSOs) and combined sewer overflows (CSOs). This is a tremendous step toward enhancing systems’ performance and safeguarding public health.”
