New Era of InfoSWMM Solidifies Its Position as Leading GIS-centric Urban Drainage Modeling and Management Solution

In its ongoing quest to equip the global wastewater industry with the world’s most comprehensive and innovative
GIS-centric modeling and design solutions, MWH Soft, a leading global innovator
of wet infrastructure modeling and simulation software and technologies, today
announced the worldwide availability of the V10 Generation of its
industry-leading InfoSWMM for ArcGIS 10 (Esri, Redlands,
CA).

The latest release is a fundamental advance in the company’s flagship ArcGIS-centric urban drainage modeling and design product — a step that
firmly establishes InfoSWMM as the number one geocentric choice for the
effective evaluation, design, management, rehabilitation and operation of
wastewater and stormwater collection systems. The software delivers an
unprecedented combination of power, functionality, seamless ArcGIS integration
and ease of use, backed by unparalleled high-touch technical support.

InfoSWMM underlines MWH Soft’s leadership in the wastewater industry, reflecting the company’s constant commitment to delivering pioneering technology that raises the bar for urban drainage network modeling and helping
to shape the future of this critical sector.

The world’s first and only urban drainage modeling solution certified by the National Association of GIS-centric Software, the full-featured analysis and design program delivers the highest rate of return in the industry. All
operations of a typical sewer system — from analysis and design to management
functions such as water quality assessment, pollution prediction, sediment
transport and deposition, urban flooding, real-time control and record keeping —
are addressed in a single, fully integrated geoengineering environment whose
powerful hydraulic computational engine is endorsed by USEPA and certified by
FEMA. These factors and more produce an enhanced modeling experience and greater
realism of displayed results. These advantages translate to increased
productivity, reduced costs, better efficiency, and improved designs.

The software gives users unprecedented power in 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. Multiple
hydrology and infiltration methods, coupled with highly sophisticated Real-Time
Control (RTC) schemes, optimize the operational management of wastewater systems
and hydraulic structures. Unparalleled performance modeling sets new benchmarks
in scalability, reliability, functionality and flexibility within the powerful
ArcGIS environment.

InfoSWMM also serves as a base platform for advanced modeling, operational, and capital planning extensions. Some of these
critical applications include InfoSWMM 2D (two-dimensional surface
flood modeling), CapPlan Sewer (risk-based capital planning integrating
modeling and GIS), and RDII Analyst (rainfall dependent inflow and
infiltration planning and analysis).

“ArcGIS 10 will be adopted very quickly by the wet infrastructure modeling community, and it is critical to the
MWH Soft customer base that InfoSWMM be ready for that migration,” said
Paul F. Boulos, Ph.D., Hon.D.WRE, F.ASCE, President and Chief Operating Officer
of MWH Soft. “We are thrilled to benefit the extended wastewater and urban
drainage modeling communities by making this best-in-class product available for
the powerful new ArcGIS 10 platform.”
