Case Study – Accreditation for the efficient use of water


Learn how ILAC member EMA ac, and accredited inspection bodies, are helping the Mexican State to administer, manage and preserve the quality and quantity of water within their economy.

“At present, the extraction of national waters in the country faces a principal-agent problem caused by information asymmetries relating to the actual amount of water extracted by users. This situation leads to inefficiency in the use of water and, at times, to the under-declaration of volumes to the Mexican authorities.

The national water program in Mexico, since its publication in 2019, has designated the NMX-AA-179 standard as mandatory. In this regulation, it is established that both the ISPs and the Inspection Units are responsible for the selection, installation and operation of the meters or measurement systems, as well as the remote transmission of the measurement information to the authority. In addition, they play a crucial role in ensuring the correct measurement of national waters through the conformity assessment procedure.

Due to these circumstances, it is imperative to make an accurate measurement of the volumes of national waters extracted. This action contributes significantly to counteracting existing information asymmetries, thus strengthening transparency and efficiency in the management of this vital resource.”
