New Version 6.0 of InfoWater UDF Saves Time and Money

  19/11/2009
MWH Soft, an innovator of wet infrastructure modelling and simulation software and technologies, has released version 6.0 of its InfoWater UDF software. The new release, which utilises both the MWH Soft InfoWater and ESRI (Redlands, CA) ArcGIS technology, provides substantial updates based directly on client feedback and real-world implementation of unidirectional flushing programs.
 

Unidirectional flushing (UDF) is the most effective way of cleaning water mains and maintaining water quality and system capacity. It also requires the least amount of water compared to other cleaning methods. In this approach, valves are closed and hydrants opened to create a one-way flow. This high-speed flushing increases the swiftness of the water flow in the mains, maximising shear velocity near the pipe wall. This produces a scouring action that effectively removes sediment deposits and biofilm.

 

UDF can help improve water quality by restoring the disinfectant residual, reducing bacterial regrowth, dislodging biofilms, removing sediments and deposits, controlling corrosion, restoring flows and pressures, eliminating taste and odour problems and reducing disinfectant demand throughout the distribution system. These benefits can also prolong the life expectancy of the system and reduce the potential for waterborne disease outbreaks.

 

Unique in its class, MWH Soft InfoWater UDF capitalises on the intelligence and versatility of the GIS geodatabase architecture in combination with advanced network hydraulic theory. Its advanced capabilities can help water utilities develop effective unidirectional flushing sequences for each flushing zone, quickly identifying which fire hydrants and water main valves should be manipulated for proper cleaning while avoiding excessive pressure drops and maintaining the desired level of hydraulic performance in the system.

 

The program also computes minimum flushing time, total flushing volume and pipe length, flushing velocity and shear stress for every pipe in the sequence and available flow at the minimum residual pressure. The hydraulic impact of each flushing sequence is monitored to ensure that the desired minimum pressure is maintained throughout the system. InfoWater UDF also generates detailed reports of flushing sequences showing which fire hydrants and water main valves should be manipulated to assure optimal cleaning. Both minimum velocity and minimum shear stress criteria can be specified.

 

Upgrades to InfoWater UDF v6.0 are now available worldwide by subscription. Subscription members can immediately download the new version free of charge. For the latest information on the MWH Soft Subscription Program, visit http://www.mwhsoft.com
