Mexico City, February 17 – The Mexico City government has unveiled a comprehensive plan to modernize its hydraulic infrastructure in anticipation of the upcoming rainy season. This initiative, backed by a 7 billion peso investment for 2026, aims to mitigate the risks associated with excessive rainfall and guarantee water supply for its residents. The program includes 643 public works and will leverage satellite technology to prevent disasters in busy thoroughfares.
When Does the Rainy Season Begin in Mexico City?
The rainy season is formally expected to commence in June. However, last year saw an atypical start with intense rains arriving as early as May. Head of Government, Clara Brugada Molina, expressed hope for a more predictable season this year, noting the significant increase in rainfall last year.
“The rains arrive in June, I hope in June, if they say they are not as strong as last year,” said Brugada Molina. Last year was particularly challenging due to a 43% increase in rainfall. Historically, September typically records the highest pluvial activity in the capital, with the previous cycle registering 83% more water than the usual average.
Key Avenues Prone to Flooding in Mexico City
Calzada Zaragoza remains one of the most critical points, consistently experiencing excessive water saturation. This thoroughfare, along with the Metro La Paz area, presents a significant logistical challenge for metropolitan transport. Other vulnerable areas include major avenues in the Iztapalapa and Tláhuac boroughs, as well as the Xochimilco area. Local authorities have identified that accumulated trash contributes to 80% of these floods.
“We hope that key places like Tláhuac, which used to flood with a small rain, will now be resolved,” stated the head of government. Works on collectors aim to channel water efficiently.
Mexico City’s Strategy Against Floods and Drought
The 7 billion peso investment for 2026 is allocated to 643 public works. Priority will be given to the maintenance of electromechanical equipment and the construction of 10,000 meters of new collectors. To combat drought (estiaje), which refers to the lowest water level or minimum flow at certain times of the year, 300 liters of water per second will be recovered through leak repairs. This action is equivalent to distributing approximately 3,000 water tankers daily to neighborhoods.
“In 2026, we are increasing investment in works by 77%,” affirmed Brugada. The objective is to transition towards a circular water model that returns water to the subsoil. Satellite intelligence will also be deployed to scan 800 kilometers of underground collectors. This technology will detect cavities before they become dangerous sinkholes for motorists.
Furthermore, the desilting target will be quadrupled to reach 1,200 kilometers of clean drainage. Mario Esparza Hernández, head of Segiagua, reiterated that surveillance in the systems will be reinforced. “We estimate that 50 to 80% of floods will be mitigated,” explained engineer Esparza Hernández regarding the expected impact.
