Real Losses
= 20 million mc/year
(1,2 million €/year)
(marginal cost = 0.06 €/mc)
Apparent Losses
= 9,6 million mc/year
(5,8 million €/year)
(sale price = 0.6 €/mc)
Electric energy
consumption
= 100 million kWh/year
(16 million €/year)
is the major factor for Milan

Projects: Advanced Pressure Management - Abbiategrasso PMZ
Real Time pressure management at the critical point by means of:
PRV (pressure reducing valve)
VFD (variable frequency drive) at Abbiategrasso pumping station
Reduction of 10 / 15 meter of Average Pressure
Results:
- Reduction of energy consumption = 18 %
- Reduction of leakage volume = 22 %
PMZ
«Abbiategrasso»116 km mains
1628 clients (condos)
Payback Period 1.5 year
