Rainy Season 2026: How to Request Free Storm Drain Clearing in Mexico City; Step-by-Step Guide

Mexico City residents facing severe flooding after recent heavy rains can now utilize an official, cost-free mechanism to request the clearing of clogged storm drains. The city's drainage system has struggled to cope with intense precipitation, leading to widespread water accumulation on streets and in neighborhoods.

The process for reporting obstructed drains, whether by garbage or other debris, is managed through the official platforms of the Mexico City government. The procedure is available year-round to prevent greater risks to urban infrastructure. To initiate a digital report, individuals must access the Unified Citizen Attention System (SUAC) website, log in with their Llave CDMX account, provide contact information, and pinpoint the exact location of the affected drain.

Users are also encouraged to upload up to five supporting digital files, such as photos or PDFs, showing the condition of the drain or the extent of the flooding, with each file not exceeding 10 MB. After submitting the report, a folio number will be provided for tracking the status of the request. This digital method aims to streamline the process and ensure timely intervention by specialized crews.

For those unable to use the online system, alternative immediate assistance channels are available. These include calling *0311 or Locatel at 55 5658 1111, available 24 hours a day. Residents can also send incident details and photos via WhatsApp to 55 6099 0025, contact the System of Water of Mexico City (SACMEX) directly at 55 8957 4950, or visit the Citizen Attention Service Centers (CESAC) in their respective mayoralties for in-person assistance.

The rainy season, which formally runs from May 15 to November 30, is a period when authorities urge the public to use these reporting systems proactively to mitigate the impact of heavy rainfall on the city's infrastructure.
