The Social Water Bonus is granted to users in a condition of economic hardship, to beneficiaries of citizenship income or citizenship pension. It is a measure to reduce the cost of the water service only, rebating the cost of 50 litres per day per person. From 1 January 2020, the tariff applied to the discount in the bill will be calculated on the entire integrated water service, i.e. aqueduct, sewerage and purification.
