The volume in m3 recorded by the meter except when it has not been possible to read the meter (estimated consumption). Water consumption is used as the basis for calculating wastewater collection and treatment. The bill for the first half-year is an estimate based on half of the previous year’s consumption. The bill for the second half-year is an actual bill based on a reading of the meter by SIEAM agents.
The Adour Garonne Water Authority manages the territory’s resources by constructing “water plans” in every catchment basin and providing financial support to communes to help them equip themselves in accordance with these plans.
