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)

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
