Water Source

SACMEX (Sistema de Aguas de la Ciudad de México) supplies the capital from the Cutzamala aqueduct system and deep groundwater wells. Land subsidence from over-extraction has damaged pipes throughout the distribution network.

Contaminants & Concerns

Bacterial contamination from cracked and leaking pipes is common. Heavy metals, sediment, and residual chlorine levels vary widely by neighborhood due to infrastructure damage caused by subsidence.

Tips

  • Buy garrafones (20-liter purified water jugs) from trusted brands like Bonafont or Ciel for daily use
  • Use purified water for brushing teeth as well as drinking
  • Street food vendors typically use purified water for ice and drinks, but confirm before consuming
