WATER OPTIMIZATION FOR NETWORK EFFICIENCY

APPLYING EFFECTIVE TOOLS FOR REDUCING NON-REVENUE WATER WITHIN A MAJOR WATER UTILITY

© EPAL S.A. All Rights Reserved.

OUR GOAL IS EFFICIENCY

Water losses within distribution systems are a global problem, butthey must not been seen as inevitable.

EPAL, as a specialist in water distribution, has established itself as acompany with the ability to anticipate and resolve problemsassociated with water losses.

WHAT IS EPAL

FROM 1868 - 145 YEARS

BULK SUPPLY to around 2.5 million people in 34 municipalities in and around the Lisbon area

DIRECT SUPPLY to 350 000 domestic and commercial customers within the City of Lisbon

Production capacity totals more than 1 000 000 M3/DAY

With 740 employees, EPAL is the largest water supplier in Portugal with a net profit of €43 M AND a turnover of €152M in 2011

NON-REVENUE WATER (NRW) SITUATION


Adopted strategy focuses on:

• Segmentation & continuous network monitoring

• Development of analysis systems using internal resources

• Optimization of Active Leakage Control actions

• Continuous improvement based on experience and results

• Simple and effective analysis processes

• Focus on what is essential and control costs

POLICY & STRATEGY ADOPTED

OBJECTIVE: Reduce Non-Revenue Water in the Lisbon distribution network from around 25% to sustainable levels of less than 15% within 3 years
