Virginia’s Most Populous County Adopts MWH Soft ArcGIS-Centric Modeling Technology


Fairfax County Wastewater Management Agency Adopts InfoSewer Suite to Support CMOM Compliance

Broomfield, Colorado USA, August 2, 2006 - MWH Soft, a leading global provider of environmental and water resources applications software, today announced that Fairfax County Wastewater Management, Virginia, has selected MWH Soft’s InfoSewer and InfoView geospatial modeling and design software to aid in managing its large and complex wastewater collection system. The software will be used to help the county comply with the Environmental Protection Agency’s Capacity, Management, Operation, and Maintenance (CMOM) program, whose goals are to eliminate sewer backups and overflows, extend the reliability and integrity of sewers, increase customer satisfaction, and implement improved system rehabilitation efforts at maximum cost savings.

Located in northern Virginia along the western bank of the Potomac River, Fairfax County is the largest jurisdiction in the Washington, DC, metropolitan area, with a population of about one million. The county’s Wastewater Management Agency (WWM) provides sanitary sewer services to about 88 percent of the residents of northern Virginia through a system of more than 3,300 miles of sewer lines, 90,000 manholes, 65 pumping stations, and 53 metering stations covering a service area of nearly 234 square miles. Arlington County, Fort Belvoir, the cities of Falls Church and Fairfax, and the towns of Herndon and Vienna also use the system. WWM plans to fully integrate InfoSewer with its existing GIS infrastructure, resulting in the comprehensive hydraulic capacity analysis needed to optimize capital planning and support the agency’s preventative sewer system maintenance management program.

Providing direct support to geodatabases, the innovative network modeling technology of the MWH Soft geospatial software suite addresses every facet of utility infrastructure management and protection - delivering the highest rate of return in the industry. With direct integration of advanced hydraulic, water quality and hydrologic modeling functionality and geospatial analysis technologies, the suite effortlessly reads GIS datasets; corrects network topology problems and data flaws; extracts pertinent modeling information; and automatically constructs, loads, calibrates and generates credible sewer collection system models with astounding speed. The suite also allows users to share mission-critical GIS and modeling information in real time over the Internet and corporate intranets. Once models have been established, users can easily run and simulate various conditions, pinpoint system deficiencies, and determine the most cost-effective physical and operational improvements and security upgrades to achieve optimum performance and regulatory compliance while improving community relations.

“We’ve built a very effective GIS framework for our wastewater collection system in accordance with CMOM, resulting in improved sewer maintenance and management techniques” said Gilbert Osei-Kwadwo, P.E., Engineering Branch Manager for Fairfax County Wastewater. “InfoSewer linking directly to this enterprise GIS system will allow us to quickly and accurately evaluate the hydraulic capacity of our sewer system-determining base and peak flows, potential bottlenecks, and cost-effective improvements that will stand the test of time and keep our system operating efficiently well into the future.”

“We are delighted that the Wastewater Management Agency of Fairfax County has selected our advanced GIS-centric modeling software to round out its CMOM program,” said Paul F. Boulos, Ph.D, President and COO of MWH Soft. “WWM is clearly aiming for a big technological impact, one with the power to deliver dramatically improved efficiency and enhanced service quality to its customers. We are proud to offer the high-performing software that will enable this prominent agency to set itself apart, better manage its infrastructure, and effect maximum savings.”
