One in five litres of water collected, processed and piped to the consumer simply is lost along the way, never reaching the tap, according to Portugal’s Regulatory Authority for Water and Waste Services (ERSAR).
The consumer is still paying for this leakage despite not receiving the supply with 66% of councils recording losses exceeding 19%. Over 100 councils waste more than 30% of the water and 45 councils lose more than 40%.
