The Resolution issued by the MADS stablished the provisions related to the use of wastewater. This Resolution applies to environmental authorities and users, so that water reuse is promoted as a practice to improve efficiency in the use of resources.

This new administrative act defines wastewater as water used or served, of domestic or non-domestic origin, and adds other relevant definitions. It also establishes that any user of the water resource may recirculate its wastewater, without requiring environmental authorization, if it is technically and economically feasible. It also states that the obtention of a water collection permit will be necessary to acquire the right to use wastewater as a public good.

According to the Resolution, the Environmental Authority must be kept informed of all technical information of the management and prevention of risks associated with the use of wastewater.

Finally, those applications or modifications of wastewater collection permit that were filed in legal and due form before the entry into force of this Resolution, will continue to be governed by the provisions in force at the time of filing. However, a maximum term of six (6) months is granted so that the applicants may apply the new legal regime.
