While in 1992 there were only 394 plants treating 30.55 m 3 /s of wastewater, today the number of treatment plants has increased to more than 2536, providing sanitation for 123.92 m 3 /s of municipal wastewater (CONAGUA 2016a, b).
  • Is there a need for a low-cost wastewater treatment system in Mexico?
  • As in many other developing nations around the world, there is a great need in Mexico for low-cost, low-maintenance wastewater treatment systems that are both economically and environmentally sustainable. In 2005, 24.3 million Mexicans lived in villages of less than 2500 inhabitants and 14.1 million lived in towns with 2500-15,000 inhabitants.
  • How is wastewater reuse performed in Mexico?
  • The wastewater reuse in Mexico is performed in WWTPs by implementing two main types of municipal wastewater treatment processes: primary and secondary. The latter is the most common with 1912 WWTPs that deliver 92.4% of the total treated flowrate of wastewater, mainly via lagoon stabilization systems and activated sludge.
  • Does Mexico have a normative framework for wastewater treatment?
  • In the first section, a comparative and critical analysis of the normative frameworks of Mexico and several countries worldwide for wastewater treated for discharge and for reuse is presented.
