President Claudia Sheinbaum announced an investment of 20 billion pesos to clean up and restore the Atoyac, Lerma-Santiago and Tula rivers. The goal is to keep them permanently clean.
“We chose these three rivers because, according to Conagua, historically they are the most polluted,” Sheinbaum said in the morning conference. “We have invested close to 2,500 million pesos between 2025 and 2026, but in total there are 20 billion.”
The plan will benefit 25 million people in 10 states. The actions include marginal drainage, wetland treatment plants, desilting, reforestation and elimination of landfills.
Details by river
The Secretary of the Environment, Alicia Bárcena, reported that the Lerma-Santiago river covers 1,360 km and benefits 21.4 million inhabitants. Tula has 191 km for 0.8 million, and Atoyac 162 km for 3.7 million.
More than 340 km have been walked, 322 sites have been sampled and 3,202 polluting discharges have been detected. 479 clandestine dumping sites and 460 priority industries were also identified.
Four goals
- Improve water quality: 10 new treatment plants, rehabilitation of 23 more, 94 km of collectors and 280 inspections.
- Ecosystem restoration: 24 km revegetated, 4,639 hectares reforested and 8,243 hectares intervened in natural areas.
- Prevent flooding: 41 km of clearing, slope stabilization and 28 monitoring stations.
- Reconnect the population: 9 parks and more than 40 thousand people in cleaning days that collected 4 thousand 667 tons of garbage.
