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
