Using valve manipulation to manage discolouration risk in drinking water distribution networks

“There are several methods to reduce the risk of discolouration in drinking water distribution networks due to the accumulation and mobilisation of particles, such as flushing the network, controlling sediment entering the network and preventing sediment accumulation through regular resuspension. To test this third option, valve manipulation was carried out in the networks of four Dutch water companies and compared with reference areas. Mirjam Blokker, Henk Vogelaar, Karel Goos and Jan Vreeburg discuss the results of this research”
