Abstract

The configuration of most water distribution systems have evolved over time developing almost organically as additional population centres have expanded the network. Unless periodical reviews of the distribution infrastructure are carried out water networks become chaotic resulting in inefficiencies in both water supply transfer capacity and distribution costs. Maintenance is an ongoing process for all UK water companies and at present most companies are compiling programs to replace aging key assets within their distribution systems. It would be prudent under these circumstances to consider if the configuration of the distribution network as a whole can be improved when asset replacement is scheduled. At Northumbrian Water, novel control valve design and new control paradigms have been combined to develop a self-controlling water distribution system that simplifies network control improves pressure management and reduces distribution costs, leakage and burst rates. Keywords: water distribution networks, asset lifetime, automation, cost minimisation, valve technology, pressure management.
