Bentley Ships WaterGEMS V8 XM Edition; Winner of AWWA's 2006 People's Choice Award Is First in Industry To Bring Together ArcGIS, MicroStation, AutoCAD, and Stand-Alone Users

Bentley Systems, Incorporated today announced the
commercial release of WaterGEMS V8 XM Edition, the only water
distribution modeling solution to unify modeling across MicroStation,
ArcGIS, AutoCAD, and stand-alone platforms.
The 2006 winner of the AWWA People's Choice Award as the most
useful new product, WaterGEMS V8 XM goes beyond GIS-centric products,
providing a true data-centric solution. This means that water
utilities and consulting firms can, for the first time, leverage the
benefits of ArcGIS integration without sacrificing interoperability
with the AutoCAD, MicroStation, and stand-alone platforms.
"Because every modeling project we do is a brand new challenge, we
need water resources technology that enables us to stay flexible,"
said Earl Schneider, a senior associate at Hatch Mott MacDonald, a
full-service engineering company. "Though we typically use the readily
accessible stand-alone environment for the majority of our modeling
work, the new WaterGEMS also gives us the ability to deliver CAD-based
models while still achieving high levels of functionality,
performance, and integration with ArcGIS."
Commenting on the new WaterGEMS, Robert Mankowski, director of
geospatial product management for Bentley, said, "After introducing
the first-ever ArcGIS-integrated water model in 2002, we are now
delivering a much faster and tighter integration for ArcGIS users
without suffering the restrictions of a GIS-centric paradigm. With
WaterGEMS V8 XM Edition, a single geodatabase can be shared and
collaboratively maintained by ArcGIS, AutoCAD, stand-alone, and now
MicroStation users."
WaterGEMS V8 XM Edition extends every piece of functionality
across all the included CAD, GIS, and stand-alone platforms. For
example, GIS users can now exercise total control over engineering
units directly within ArcGIS's attribute tables, using the same
FlexTables technology they can find in the other included platforms.
Additional new features of WaterGEMS V8 XM include:

-- Criticality Analysis Center: This comprehensive utility helps
identify critical assets in water distribution infrastructure
and evaluate the risk associated with their failure.

-- New modeling elements: Hydrants, isolation valves, and
variable speed pump batteries have been added to the framework
to support asset management and hydraulic modeling workflows.

-- Pressure-dependent demands: Users can define demands as a
function of pressure to effectively model intermittent water
supply scenarios, sprinkler heads, and unaccounted-for water.

-- Centralized water demand management: Users can streamline
water consumption estimation with new geospatial demand
allocation methods, unit demand engineering libraries, and
global management for simple, composite, and
pressure-dependent demands.

WaterGEMS V8 XM Edition is available today to all Bentley SELECT
subscribers. For more information on WaterGEMS V8 XM Edition, please
