The increasing pressure on global resources continues, and will continue to do so until appropriate engineering solutions and technologies are developed to meet the needs. The UK based, venture capital funded company, i2O Water ltd, are proving how this can be done to the benefit of both water companies and their customers. Often excess pressure exists in distribution networks. This can lead to excessively high levels of leakage on the network and poor pressure being experienced by the customers. The i2O solution is an integrated system of wireless remote sensors and controllers, centralised server architecture, intelligent learning algorithms and a web interface for remote monitoring and control. The controllers are installed on both existing variable speed drive pumps and Pressure Reducing Valves (PRVs). The intelligent learning algorithm uses the pressure and flow data from the remote sensors to model the characteristics of the network. After developing the operating model it continues to update continuously, adapting automatically to changes in the network characteristics that occur for many reasons including; changes in customer demand, network re-zoning, seasonal weather influence and changing industrial usage patterns.
