Bayesian networks and their associated methods are especially suited for capturing and dealing with uncertainty. They can be successfully applied both in engineering sciences and in reliability analyses of water distribution systems. In this paper we propose an interactive Bayesian network and a decision-theoretic system which intend to monitor water loss, predict likely outcome and select appropriate decisions.
Large regional water companies, like California American Water Company, which services the central coast of California, have already invested in high performance flow measurement instrumentation to better understand its usage. Most Americans receive water service from community water and wastewater utilities. It is less known that private water companies own nearly 16% of the nation’s community water systems. Carmel Riviera Mutual Water Company is one such small rural water company. The company serves up...

SIE Renom Chalaronne wanted to reduce losses in drinking water and increase its network performance, a goal which became increasingly critical in light of the Grenelle II Law. This law stipulates that network yield must be greater than 85% in urban areas and between 65% and 85% in rural areas. SIE Renom Chalaronne was able to use a combination of Hydreka products to optimize the pressure in their network, leading to huge gains in water conservation, and reduced operating costs. The region, located rurally on the...
In a perfect world, water networks have 100% uptime and adequate pressure. In reality, customers experience loss of pressure, water quality issues, and outages. In under-invested networks, this is even more frequent. Yet, providing a good customer experience is possible. Detecting problems before customers do is not a fortune teller’s trick, but something that can be achieved with the right tools and processes in place. So how can Network Engineers achieve Zen for their networks? Here are three main...
Their Challenge With water loss up to 30 per cent, Metropolitan Water Authority (MWA) in Bangkok, Thailand, installed pressure reducing valves throughout the city and its suburbs. The valves controlled nighttime pressures accurately, preventing leaks and breaks. However, in some areas, high demand during the day caused the pressure to drop to 10 psi (0.68 bar) or less. Without sufficient pressure differential, regular pressure reducing valves would close, cutting off supply to consumers. Our Solution Because...
