Wessex Water Expands Collection System Modeling Efforts Using InfoWorks CS

Posted: Monday 14th June 2010

Leading United Kingdom Utility Looks to MWH Soft Technology for Advanced Sewerage Modeling and Analysis.

Wessex Water, United Kingdom, has expanded its use of InfoWorks CS to include InfoWorks 2D’s two-dimensional above-ground modeling and the capability to model large and complex collection systems of up to 100,000 nodes. The decision further substantiates MWH Soft’s worldwide leadership position in engineering-GIS modeling and management software for water and wastewater utilities.

Wessex Water provides sewerage services to 2.6 million customers covering over 3900 mi2 (10,000 km2) in the southwest of England, including the urban areas of Bath, Bournemouth, Bristol, and Poole. It has been recognized by the UK’s water industry regulator, Ofwat, as one of the most efficient water and sewerage companies in England and Wales. Its collection system comprises 10,400 mi (16,700 km) of sewer pipelines, 1455 pumping stations, and 405 sewage treatment facilities.

“InfoWorks CS is a critical part of our technical engineering infrastructure,” said David Searby, Technical Manager-Sewerage for Wessex Water. “Providing high quality sewerage services to millions of customers every day requires a clear understanding of both the short- and long-term decisions of our operators and engineers. InfoWorks CS allows us to quickly and easily simulate an almost limitless number of conditions and see how they affect the collection system both above and below ground.”

InfoWorks CS provides water utilities with a uniquely effective tool for undertaking hydrological modeling of the complete urban water cycle. Essential for identifying and justifying cost-effective infrastructure improvements, it also provides a practical method for operational control, including real-time control, of the wastewater network. Other applications include urban flooding and pollution prediction and the modeling of water quality and sediment transport throughout the network.

In addition to supporting fast and accurate network modeling, the software features specific tools to support the modeling of subcatchment takeoff and infiltration. With its exceptionally fast and robust simulations, InfoWorks CS facilitates the swift modeling of total networks or any sub-network.

InfoWorks 2D facilitates fast, accurate and detailed surface flood modeling. Two-dimensional (2D) simulation is better suited than one-dimensional simulation (1D) for modeling flows through complex geometries (such as urban streets and buildings, road intersections and other transport infrastructure), and open ground, where either source or direction of flow is problematic to assume. In urban areas, the situation is further exacerbated by sewer networks, where flows can both enter and exit the system during flood events.

“The accelerated adoption rate of MWH Soft technology across the industry reflects a powerful trend among water and wastewater utilities toward MWH Soft products,” said Andrew Brown, the company’s EMEA Regional Manager. “The shift is being driven by a range of compelling factors, including speed; brevity of learning curve; powerful, comprehensive feature sets; and superior technical support. We are pleased to see progressive utilities like Wessex Water continue to expand their commitment to using world-class software tools to benefit their customers.”
