  • 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.
  • How many wastewater treatment plants are there in Mexico?
  • Historically in Mexico , the number of WWTPs facilities has risen steeply. 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).
  • Why are sludge treatment plants not working in Mexico?
  • Unfortunately, most treatment plants operate below capacity owing to a lack of maintenance and paucity of properly trained personnel. The main types of treatment systems applied in Mexico are activated sludge and waste stabilization ponds, which treat 44.3% and 18% of the MWW collected, respectively.
  • Are Mexican standards a model for regulating wastewater reuse in Latin America?
  • On the regional level, these Mexican standards are the model for other countries in Latin America that have neglected regulating wastewater reuse. The wastewater reuse in Mexico is performed in WWTPs by implementing two main types of municipal wastewater treatment processes: primary and secondary.
