Leakage management: planning remote real time controlled pressure reduction in Oppegard municipality

Pressure control entails the cheapest technical solution to achieve leakage reduction in water distribution networks in short-medium time horizon. This work reports the planning of remote real time controlled (RRTC) pressure reducing valves (PRV) for the Oppegard (Norway) hydraulic network. It was achieved by using an advanced hydraulic model which integrates the pressure-dependent background leakage model with the simulation of PRVs based on remote control nodes. Results demonstrate that RRTC PRVs instead of existing locally controlled ones permits the reduction of the background leakages of about 35%. This rate increases over 40% if few additional RRTC PCV are installed. (C) 2015 The Authors. Published by Elsevier Ltd.
