Project information
Project Information leaks

  • Cofinaced by EU and Ministry of Environment

  • Duration: 3 years (ended in 2011)

  • Budget: EUR 1.400.000,00

  • 2 Pilot sites: Ancona (Italy), Nicosia (Cyprus)

  • 6 partners (4 engineering consultants + 2 water utilities)

Leakage control system is widely known so why is leakage so high
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

Daily step by step leakage analysis
Daily Step by Step Leakage Analysis high ?

  • Extract minimum night flow

  • Subtract Customer Consumption

  • Quantify Leakage

  • Assess if leakage increasing

  • Decide if worthwhile to locate and repair leaks

The Solution isAutomate the process

Autoleak features
Autoleak Features high ?

Automatically for every DMA AUTOLEAK

  • Determines current recoverable leakage

  • Extrapolates rate of rise from historical data

  • Quantifies value of predicted lost water (Benefit)

  • Compares with cost of intervention

  • Decide if worthwhile to intervene

Autoleak operative principle
AUTOLEAK – Operative Principle high ?

Intervention if

V > X

Leakage calculation

Estimation of Water Recovered

Estimation of Intervention Cost

Leakage Detection (Noise Loggers)


Intervention (YES)

Calculation of cost of intervention
Calculation of Cost of Intervention high ?

  • Average Recovered Flow per Leak

  • Calculation of number of leaks to be repaired

  • Average Intervention Cost (leakage detection + repair)

Historical Intervention



Real Data from DMA

Parametric data from similar case studies

Historical cost of intervention
Historical Cost of Intervention high ?

  • Real Data from past interventions

  • Calculation of Cost and Water Recovery of past leakage intervention

  • Cost Estimation of future intervention based on the expected water recovery

Assessment of economic convenience
Assessment of economic convenience high ?

  • Total value of the recovery (V)

  • Estimated cost of intervention (X)

  • if V>X, the intervention will be worthwhile

  • Priority = (V-X)/km

Leak repair report
Leak Repair Report high ?

  • Leak repair report

    • Make records of your leak repairs

    • Provide your staff with site forms to record data

    • Create statistics of your leak repairs

    • Create Leakage Maps

Lesson learned and possible development
Lesson Learned and possible development Concentrator

  • AMR Transmission problems in Ancona (then solved)

  • Initial setup and customization necessary for each pilot application

  • AMR repeaters mount on light pole, authorization needed

  • Technology Improvement

    • Next development in data transmission (electricity, ADSL, cable? ….)

    • Full Automatic Correlation

Conclusions advantages of autoleak
Conclusions - Advantages of Autoleak Concentrator

  • Interfaces with all currently available technology including AMR

  • Data Integration

  • Makes managing leakage almost fully automatic

  • Allows to save investment focusing on interventions where the expected benefit is greater

Thank you
