MWH Soft Inc., a global provider of water resources applications software, announced that the City of Dayton, Ohio, has awarded MWH Soft a substantial contract for its ArcGIS-centric (ESRI, Redlands, CA) InfoWater software suite, plus its Platinum Subscription program. Chosen following a competitive review, the program will replace the City's existing modeling software as a key component of its comprehensive water master plan. It will be used to guide expansion and rehabilitation efforts for the City's existing water distribution system to best accommodate continued community growth. The decision points up MWH Soft's market-leading momentum in advanced geospatial infrastructure modeling solutions in North America.

The decision by Dayton's Department of Water, which delivers drinking water to all residents of Dayton and many other communities in Montgomery County, followed an extensive evaluation of leading GIS-based water modeling software packages. The assessment included a detailed feature/functionality list as well as onsite interview and presentation by software vendor representatives to key decision makers. The Department also retained the services of CH2M Hill, a leading multinational engineering firm ranked third in ENR Top 200 Environmental Firms, to assist in the software evaluation. The selection confirms the experiences of customers worldwide who are finding MWH Soft advanced geospatial technology to be the most comprehensive and easy-to-use ArcGIS-centric modeling and management system in the mid-price range, with broader functionality and a superior solution to those of its competitors.

The City's water system consists of three main pressure zones that contain six tanks, nine reservoirs, eleven booster pump stations, two water treatment plants and pump stations, 800 miles of water mains, and interconnections with eight neighboring wholesale customers. This entire infrastructure is captured in a geodatabase in ESRI's ArcGIS 9 platform. The City will use the ArcGIS-centric InfoWater solution to build, directly from its geodatabase, and calibrate an extended period dynamic simulation model. The model will be used to analyze existing and future hydraulic and water quality conditions and optimize the department's capital improvement program.
