Broomfield, Colorado USA, August 22, 2007 — In its ongoing quest to equip the global wastewater industry with the world’s most comprehensive and innovative GIS-based modeling and design solutions, MWH Soft, a leading global provider of environmental and water resources applications software, today announced the worldwide availability of the V6 Generation of its industry-leading H₂OMAP SWMM.

The new version delivers an intuitive, time-saving user interface and impressive graphics; greatly accelerates the creation of better, more accurate models; and includes more advanced design analysis capabilities than any other wastewater modeling software. The release marks the most significant milestone to date in the evolution of the company’s flagship urban drainage modeling and design product, firmly establishing it as the number one choice for the effective evaluation, design, management, rehabilitation and operation of wastewater and stormwater collection systems.

“On all fronts MWH Soft has significantly improved H₂OMAP SWMM software’s unsurpassed arsenal of powerful tools,” noted Chris Adams, Project Manager and wastewater modeling specialist for Jordan, Jones & Goulding, Inc. in Athens, GA. “The new version is very impressive and offers more capabilities, flexibility and performance improvements in its modeling, data management and results presentation tools than ever before. I have yet to use a product that offers the same combination of functionality and ease of use, backed by incredible technical support. Using MWH Soft products, I’ve been able to take on more master planning projects involving very large and complex systems by increasing my productivity while maintaining high project quality, allowing my customers to achieve earlier and more cost-effective project completion with optimized capital planning.”

The new version embodies more than one hundred customer-requested enhancements and new features, plus significant innovations that break new ground in geoengineering productivity and efficiency.

H₂OMAP SWMM is quickly becoming the must-have solution for comprehensive enterprise-wide geospatial urban drainage and sewer systems engineering. With an intuitive working environment and new cutting-edge features and improvements, Generation V6 delivers unmatched capabilities to the wastewater industry, backed by unparalleled technical support. “Our primary objective with H₂OMAP SWMM V6 was to stay very customer-focused and provide our users with exactly what they’ve been asking for most— outstanding performance, flexibility, ease of use, and engineering GIS modeling capabilities,” said Paul F. Boulos, Ph.D, President and Chief Operating Officer of MWH Soft. “Customer feedback shows that we have accomplished our goals by delivering the wastewater industry’s most advanced and comprehensive urban drainage modeling solution We are thrilled to make this one-of-a-kind product available to the extended urban drainage modeling community to help them accomplish their jobs better, easier and faster.”

The full-featured urban drainage network analysis, design and optimization program delivers the highest rate of return in the industry.  H₂OMAP SWMM addresses all operations of a typical sewer system — from analysis and design to management functions such as water quality assessment, pollution prediction, urban flooding, real-time control and record keeping — in a single, fully integrated geospatial environment. Its powerful hydraulic computational engine is endorsed by USEPA and certified by FEMA.

The program offers users unprecedented power for managing urban runoff and wet weather water quality problems in combined, sanitary and storm sewers; optimizing BMP and LID designs; and meeting SSO and CSO regulations. It also provides highly sophisticated Real-Time Control (RTC) schemes for the operational management of wastewater systems and hydraulic structures. The unparalleled performance modeling of H₂OMAP SWMM sets new benchmarks in scalability, reliability, functionality and flexibility within a GIS-based environment.

Underlining MWH Soft’s leadership in the wastewater industry, H₂OMAP SWMM reflects the company’s ongoing commitment to delivering pioneering technology that raises the bar for urban drainage network modeling standards, helping to shape the future of this critical sector. Focused on expanded geospatial functions and performance, V6 features a host of unique new capabilities to help wastewater engineers and planners develop better designs and operational improvements faster and more efficiently.

Key additional modeling tools include a new option that allows a run to ignore any flow routing and only compute runoff; a new type of pump, an Ideal Pump, which pumps at a rate equal to the inflow to its inlet node without a pump curve; and a new conduit shape that allows users to define their own cross-sectional geometry for closed conduits. For circular pipes under pressurized flow, the user can now select between the Hazen-Williams, Darcy-Weisbach (Colebrook-White) or Manning equations.

Pump startup and shutoff inlet node depths can now be supplied directly as part of a pump’s properties rather than as part of a control rule. Orifices can now have timed gate openings and closings. An initial abstraction loss can now be associated with Unit Hydrographs used for RDII inflows. A new criterion has been added to determine when a conduit has supercritical flow (based on both water surface slope and Froude number), indicating that normal flow conditions might apply. Node volumes are now initialized to take account of any initial ponding implied by the node depth. To comply more closely with standard hydraulic practice, the head across an orifice is now computed with respect to the midpoint of its opening, rather than to the bottom. Orifices, like weirs, are now treated as not contributing surface area to their end nodes.

The software’s powerful new graphical and tabular reporting capabilities include the automatic ability to visualize water level temporal variation in the channels, generate vivid profile plots between any two user-selected nodes, compute storage curve from digital elevation data, and correct shared boundaries of adjacent polygons. These capabilities also allow the use of upstream and downstream conduit inverts instead of offsets, and rim elevation instead of maximum depth for junctions. The software is also able to generate more complete tabular results, statistical reports, and summary tables for all network components.

“The accelerated adoption rate of our software clearly proves that progressive engineering organizations and wastewater utilities are choosing H₂OMAP SWMM over competitive products whose features simply do not compare to its comprehensive set of solutions,” said Trent Schade, PE, Senior Client Service Manager for MWH Soft and a leading urban drainage modeling expert. “V6 is the most significant H₂OMAP SWMM release ever — unparalleled in helping engineers analyze and optimize their systems better, faster, and more affordably. With its powerful GIS integration; ability to simulate both dry-weather and wet-weather flows; and speed and reliability in optimizing system rehabilitation, design and operation, V6 makes fast and easy work of even the most sophisticated and challenging urban drainage system analysis. Because these advantages can be leveraged regardless of users’ technical expertise, their benefits can be extended across the entire enterprise.”
