2.6 Mld m3/y water loss
Average Marginal Cost of Water (energy +
treatment): 0.087 Eur/m3
226 Mil Eur/y cost of leakage
Which is the cost of water loss in Italy?
50 million inhabitants

Why reduce leakage?
1. Extra water available where it is
needed.
2. Reduce Energy Consumption
3. Reduce Environmental Impact
4. Less investment for new plants, new
pipes, new water resources

Background
Methods and technologies for leakage control have
become familiar worldwide
But the wrong assessment of the problem can bring to
poor results and waste of money
The questions are:
Is leak intervention convenient? And how far
should we go into leak reduction?
Do we know if, where and when to look for
leaks?
Pump and Leakage Management

Leakage Percentage
Leakage level is generally expressed as a percentage
of input volume
But a percentage alone is not significant as a
Performance Indicator
Which is worst?
15% leakage in Nicosia (Cyprus)
45% Leakage in Bergen (Norway)

Leakage Control System is Widely Known:
so why is leakage so high ?
Lack of priority for leakage
Insufficient Staff
Time consuming analysis
Effort directed to emergencies

The Solution is Automate the process
Daily Step by Step Leakage Analysis
Extract minimum night flow
Subtract Customer Consumption
Quantify Leakage
Assess if leakage increasing
Decide if worthwhile to locate and
repair leaks

Conclusions
Before implementing a leakage plan, it is important to
know if it is convenient and how far to go.
PALM allows the definition of the optimum economic
target level for every network (Efficiency Calculator).
PALM helps in the initial go/no go decision.
When the leakage system is implemented it is
necessary to reduce maintenance costs.
AUTOLEAK makes managing leakage and DMA almost
fully automatic.
AUTOLEAK gives the priority of intervention.
