Water and Sewer Authority in Virginia's Second-Largest County Adopts MWH Soft Geospatial Sewer Modeling Technology

H2OMAP Sewer and H2OCalc Support Master Planning Effort and Optimizes Capital Projects

Broomfield, Colorado USA, September 13, 2007

MWH Soft, a leading global provider of environmental and water resources applications software, today announced that Prince William County Service Authority, situated in Virginia’s second largest county, has elected to adopt MWH Soft H2OMAP Sewer and H2OCalc modeling software. The programs will serve as the foundation for developing a comprehensive capacity evaluation master plan for the Service Authority’s waster reclamation system and optimizing its capital improvement program. The selection continues to substantiate MWH Soft’s leadership position in geospatial hydraulic infrastructure management in the North American market.

Prince Williams County, located approximately 35 miles southwest of Washington, D.C., is an integral part of the Washington metropolitan area. It is one of the fastest-growing counties in the nation, with a current estimated population of approximately 381,221 — a number expected to exceed 415,000 by the year 2010 and 463,000 by the year 2015. The Authority’s water reclamation system consists of 916 miles of sewer lines and 58 wastewater pumping stations with a total wastewater treatment capacity of 34.5 mgd. The Authority plans to leverage the power of H2OMAP Sewer and H2OCalc to develop cost-effective expansion and rehabilitation strategies for its wastewater infrastructure — changes designed to best accommodate rapid community growth and improve operations.

“We were looking for a comprehensive, easy-to-use, geospatial sewer modeling solution — one that combined the powerful features of GIS with advanced analysis and reporting capabilities,” said Kendra Schlueter, Project Engineer at PWCSA. “The H2OMAP Sewer intuitive interface really demystified the complex modeling process, making us feel confident about mastering the technology and being productive from day one. The software’s compatibility with ArcGIS, broad functionality, ease of use and impressive computational speed and stability makes it a great fit for the Authority’s needs. The outstanding technical support provided by MWH Soft adds to its value. These advantages and more will help us optimize our capital improvement program while continuing to give our customers the best long-term value at the best value.”

Developed and supported by industry experts, H2OMAP Sewer is used by municipal engineers, consultants, and planners worldwide to create detailed, accurate models of sanitary and storm sewer collection systems. These models enable users to assess the effect of new developments, zoning changes, and other additional loads on system flows. They also help pinpoint current and future problem areas; determine how best to restore capacity lost to infiltration and inflow with the least rehabilitation; predict unwanted overflow events and backups; develop sound, cost-effective improvement alternatives; meet environmental regulations; and enhance community relations.

The program offers fast, comprehensive hydraulic and dynamic water quality computational capabilities, including steady-state analysis using various peaking factors and automated system design and sophisticated dynamic modeling that considers flow attenuation, time of concentration, and source tracing. Other capabilities include pollutant, biochemical oxygen demand (BOD), sediment transport/deposition, hydrogen sulfide and corrosion modeling.

H2OCalc is a must-have toolbox that offers broader functionality and a superior solution to those of its competitors. It gives engineers uncomplicated access to scores of essential hydraulic computational algorithms critical to designing better systems. It enables users without expertise in this complex field to deploy these sophisticated computational abilities to streamline the hydraulic design and analysis of pumps, pipes, ditches, open channels, weirs, orifices, culverts, and inlets. By eliminating the need for messy nomographs, cumbersome spreadsheets and homegrown programs, it empowers engineers to work more effectively, improve productivity and design better systems. Other important functions include high-level surface water hydrology calculations to compute peak discharge and hydrographs for stormwater runoff.

H2OMAP Sewer continues to receive very high praise from leading utilities and engineering consultants worldwide,” said Trent Schade, P.E., Senior Client Service Manager for MWH Soft. “The software is very easy to master and use, yet powerful enough to quickly and accurately model and analyze extremely large and complex wastewater systems. New users see an immediate and dramatic improvement in the detail and complexity of their engineering GIS modeling projects. That’s the key reason behind our products unprecedented adoption and satisfaction rates.”

“Companies all over the world continue to recognize the benefits of high-performance geospatial modeling,” said Paul F. Boulos, Ph.D, President and COO of MWH Soft. “H2OMAP Sewer offers the most effective approach to maximizing the value of an enterprise’s geospatial and modeling data. That leads to faster and more informed decision making and enhanced capital planning. The amount of time, money, and resources clients save by using our products is tremendous. We’re proud that a water and sewer authority with such an advanced engineering organization and accomplished track record has invested in MWH Soft software, and very excited to participate in PWCSA’s success.”
