ARTICLE 282-C:

Taxpayers who have a plant for wastewater treatment and those who in their production processes have carried out actions to improve the quality of their discharges and these, are of a quality equal or superior to that established in the Official Mexican Standard NOM-127- SSA1-1994, they may enjoy a 30% discount on the payment of the right for use or exploitation of national waters referred to in Chapter VIII, of Title II of this Law. This benefit shall apply only to the exploitation of national waters that generate the discharge of wastewater, as long as the taxpayers comply with the provisions of the National Water Law (Ley de Aguas Nacionales), its Regulations and this Law.

The discount percentage will be applied to the amount of right referred to in Chapter VIII of Title II of this Law without including that corresponding to the consumptive use of water. In this case, the declaration of payment of right for use or exploitation of national waters, must be accompanied by the results of the water quality, issued by a laboratory accredited before the accrediting entity authorized by the Secretary of Economy (Secretaría de Economía) and approved by the National Water Commission (Comisión Nacional del Agua).
