Washington Suburban Sanitary Commission adopts software to better support master planning, operational analyses

Sponsored by

EXTON, PA, Dec. 20, 2010 -- Bentley Systems, Incorporated, the leading company dedicated to providing comprehensive software solutions for the infrastructure that sustains our world, today announced that Washington Suburban Sanitary Commission (WSSC), one of the largest water and wastewater utilities in the United States, has selected Bentley's WaterGEMS and SewerGEMS software. WaterGEMS enhances water distribution and modeling capabilities while SewerGEMS improves the modeling and management of sanitary sewer systems. Together they enable the utility to better support master planning workflows and operational analyses, and to increase efficiencies and the accuracy of data delivery in workflows between WSSC and site developers in Prince George's and Montgomery counties, Maryland. The Bentley products:

• provide state of the art modeling that performs well with large data sets,
• include advanced visualization tools,
• interoperate with other software that WSSC and site developers regularly employ,
• improve the modeling process during project reviews by reducing data entry duplication.

WSSC is deploying WaterGEMS for system-wide planning and development-level projects and SewerGEMS for site development workflows.

"Interacting with developers can be challenging, requiring frequent changes in specifications," said Richard Zambuni, Bentley global marketing director. "These are highly complex workflows, which previously required data to be manually re-entered before a new model could be generated to determine pipe sizes and the optimal network configuration. All of this takes time and can lead to costly input errors if not done carefully. When using its previous software to tackle complex projects, WSSC used to need as much as 120 days to perform hydraulic evaluations and furnish developers with pipe sizes, capacities, and the other hydraulic information needed to provide service to proposed developments. At the same time, WSSC had to perform other hydraulic reviews such as preliminary site-plan reviews, service category change requests reviews, county re-zoning reviews, private system connections reviews, water main replacements reviews, partial release reviews, and more. WaterGEMS and SewerGEMS will help WSSC work toward reducing the modeling process during these review processes."

Zambuni continued, "With WaterGEMS and SewerGEMS the WSSC management team is able to ensure consistent workflows and outputs. The software reduces the need for hard copies and is a better tool to exchange data with developers, especially when specifications change. In addition, workflows will further improve due to the ability of WaterGEMS and SewerGEMS to work directly within Esri's ArcGIS, WSSC's enterprise GIS."

Other factors in WSSC's choice of WaterGEMS and SewerGEMS include the software's ease of use and Bentley's highly flexible and comprehensive training support. In time, WSSC expects to use WaterGEMS and SewerGEMS with an enterprise-level engineering content management system to help structure workflows, both internally and with developers and contractors, further speeding project delivery.
