Revolutionary New Release Offers Unsurpassed Capabilities, Raising the Bar for Design,

Expansion and Rehabilitation of Wastewater Collection Systems

Broomfield, Colorado USA, June 28, 2006 - In its ongoing effort to provide the global wastewater industry with the world's most comprehensive and innovative GIS-centric modeling and design solutions, MWH Soft, a leading global provider of environmental and water resources applications software, today announced the worldwide availability of the V4 Generation of InfoSewer for power ArcGIS (ESRI, Redlands, CA) users.

In response to customer feedback, this latest version introduces valuable user-driven enhancements and functionalities, along with architectural and database improvements that make sophisticated sewer systems analysis and design applications fast and easy to use. V4 also debuts Automated Intelligent Design Technology, which for the first time puts expert-level, high performance techniques in the hands of every user that enable automation of the most challenging wastewater collection systems design, expansion and rehabilitation activities. These enhancements equip wastewater utilities with unprecedented power to improve system management, operation and regulatory compliance.

InfoSewer is used worldwide by municipal engineers and planners to create detailed, accurate models of sewer infrastructure systems. These models enable users to evaluate the effect of new developments, zoning changes, and other additional loads on system flows; pinpoint current and future problem areas; predict overflows and backups; and determine how to best restore needed capacity lost to infiltration and inflow with the least rehabilitation. In addition, users rely on these models to compute hydrogen sulfide generation and corrosion potential; analyze the rate of Biochemical Oxygen Demand (BOD) exertion; track sediment movement and deposition; calculate the amount of pollutant transported to the wastewater treatment plant; and assess pollutants' impacts on receiving waters. The application also provides vital tools for meeting and exceeding environmental regulations and improving community relations.

Toppling the notion that powerful software is necessarily complex, InfoSewer V4 delivers advanced design functionality and exponential increases in efficiency while simplifying its use. Users can now quickly and reliably design new sewer collection systems that consider standard design criteria such as flow depth-to-pipe diameter ratios, velocity, slope, soil cover depth, and pipe crown drop. Using user-input manhole locations, InfoSewer V4 calculates the optimal pipe size and slope, invert elevation of conduits and manholes, soil cover depths at both ends of each pipe section, and cost of excavation and reinstatement to meet target design criteria. Results can be reviewed using profile plots, color coding of sewer maps, or comprehensive tabular reports. They can then be automatically updated in the model database, simplifying the model building process.

Together, these important capabilities will help wastewater utilities worldwide dramatically raise productivity and efficiency by rapidly developing practical and optimal capital improvement strategies that minimize costs while improving system reliability, integrity and performance. By making engineering professionals more productive and their organizations more competitive, V4 delivers benefits utilities can pass on to their customers through better designs and higher quality standards, achieved in a shorter turnaround time.

"InfoSewer is the ideal choice for organizations that need a single reliable, affordable and easily implemented solution for advanced geocentric modeling and design of sewer collection systems," said Paul F. Boulos, Ph.D, President and Chief Operating Officer of MWH Soft. "The program is built on the experience our company has gained from our large user community. Their input continuously drives us to add new functionalities and set new standards through pioneering technology. Our latest version gives users the trusted tool they need to identify the most cost-effective ways to keep their systems operating efficiently into the future. We are confident that it will influence wastewater design engineering for years to come."
