Using integrated modeling approach for water loss/leakage reduction is relatively new to majority of consulting and utility engineers. Bentley has developed an innovative tool that is ease-to-use and powerful for predicting water leakage locations. Internet portal Bentley Water Loss Reduction Technology is built for sharing the information, expertise and experience with water industry worldwide.

Since computer model was invented for water distribution system analysis in 1970's, engineers have been challenged to build an accurate hydraulic model for a water system. The following paper has been published in the journal of Water Resources Management to elaborate Bentley's optimization modeling technology for assisting engineers to build effective hydraulic models of  municipal water systems. 

Evolving Effective Hydraulic…

You must have heard about carbon footprint, but may not know what water footprint is.

While sitting at WEX2008 presentation given by Johan Kuylenstierna, the chief technical advisor to UN Water, one slide struck me with how much water is actually embedded in a product.

Here are some typical examples of how much water (in litters) is embedded.

one hamburger (150 g) embeds 2400, 1 glass beer (250 ml) 75,…

Bentley sponored and organized Water Loss Seminar and Workshop from Jan. 28-30 2008 in Marbella, Spain. See more information at www.bentley.com/waterloss2008.

The event attracted more than 60 attendees from over 20 countries. More than a dozen renowned speakers discussed the latest research and development work on managing and reducing water loss in water distribution systems.

Some testimonials from the attendees…

Water utilities provide clean water service to local communities and charge the service by the metered water consumption. However, not every drop of water produced at a water treatment plant reaches customers and generates the revenue for water companies. Instead, a significant portion of drinking water is lost, due to either water dripping away from the distribution pipelines or the unauthorized water usage. Consequently…

Some but certainly not many years ago, I read an article in the last issue of Time magazine of a year, listed ten hottest things that would happen in coming years, one of them is Bloging. I was a little suspicious as I am always to those predicitions. Well, I was proved deadly wrong when I watched how popular the internet social networking has become, don't mention how much those 'virtual' companies are valued or acquired…
