DESCRIPTION
Presentation for the Suez World Technical Congress held in Paris 4/3/2014, showing how ASTOSAM managed to implement a sectorisation project in less time and with less cost by using dynamic microsectorisation, water pressure powered valves to close sectores and modulate pressure, as well as wireless flow meters designed by Aqualogy

Making sure that:
• No water quality or pressure problems occur
• Normal distribution conditions are respected
• The existing infrastructure is taken advantage
of to install actuators
• CAPEX are minimized
• The implementation is quickly achieved, without
modeling the complexity of the loops and
meshes in the network
• Absolutely robust and reliable, with minimum
maintenance costs
Improve the efficiency by means of providing minimum night flows for each sector on a daily basis
