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.

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
