Focus : The challenges of managing water losses from larger diameter mains, or those losses upstream of the distribution networks.
Managing Upstream Losses
A lot of emphasis has been placed on managing losses in distribution systems, through the establishment of DMAs, targeted leak detection, pressure management, systematic pipe replacement and now permanent monitoring. However, very little has been done on the transmission/trunk main networks, either because it has been too difficult to manage, or the water utility believed incorrectly that this was not a problem.
Many water utilities are now starting to realise that the neglect of the upstream pipework has resulted in deterioration in their condition, which now means higher losses than was considered. Replacement of these large and generally metal pipes would incur huge costs, so management of their leakage levels, system pressures and future condition are imperative.
