ANEAS participates in the ALADYR 2018 Seminar

With the conference “Analysis of the water policy of wastewater treatment in Mexico”, Roberto Olivares, Director General of ANEAS, opened the ALADYR 2018 Seminar I Mexico Edition, emphasising the need to reconsider the country’s wastewater treatment policy, since “it is designed to build and operate WWTPs; not to comply with the fundamental objectives of sanitation, which are to preserve quality, prevent deterioration of water bodies and promote reuse.”

Mr. Olivares presented the current treatment policy based on the schemes of the National Development Plan 2013-2018 and compared them with the results obtained so far. He explained that although the national average of wastewater treated is above 50%, it couldn’t be forgotten that the averages hide the gaps between states and regions.

For example, “Mexico City has significantly increased the wastewater treatment level with the start-up of the Atotonilco WWTP, and given the treated volume (23.26 m3/s) it will increase the national average, but it will not solve the problem”. In addition, he said that the treatment policy focuses on municipal waters, leaving aside industrial waters, which on average treat only one third of the wastewater generated.

He also made the comparison of the water quality levels between 2010 and 2014, in which there is a deterioration of the water bodies with an excellent quality and those that were considered with some degree of contamination. In addition, he stressed that the discharge of untreated industrial wastewater, which contains toxic pollutants such as heavy metals, cyanides, solvents, and hardly biodegradable organic matter, threatens the health of the population and ecosystems.

For this, he stressed that the treatment policies should be geared towards the development of comprehensive sanitation projects with a shift in focus that considers both building WWTPs and the reuse.
