# Piedras Negras water and waste management > Live situation record from CLSTR: https://clstr.news/situations/piedras-negras-water-and-waste-management > Updated: 2026-08-27T01:26:15.000Z. Sources: 10. Developments: 5. In Piedras Negras, municipal authorities are managing various aspects of water and waste infrastructure. Initial reports indicated temporary water pressure reductions due to valve repairs at the Río Bravo pumping station. Concurrently, the municipal government began feasibility studies regarding a potential tire-recycling plant to manage landfill capacity. Mayor Jacobo Rodríguez has proposed a new financial model for wastewater management, suggesting the municipality “sell the drainage” to the Coahuila State Government. Under this plan, the state would be charged for wastewater arriving at the local treatment plant, which is currently under state administration and receives city wastewater for free while the municipality absorbs infrastructure costs. Legal experts have noted that such a change would require navigating existing legal frameworks, as drainage and wastewater are defined as municipal public services under Coahuila law. Additionally, the municipality is seeking to secure up to 10.5 million pesos for hydraulic infrastructure projects through CONAGUA programs. While the payment process for the Water Rights Program (PRODERA) is currently stalled, the municipality intends to finalize adjustments before the October 31 deadline. Recent developments have brought scrutiny to the municipal water and sewage system (SIMAS) regarding its operational capacity. Despite administration claims of financial and operational recovery, private contractors have been observed performing tasks traditionally handled by SIMAS. For instance, personnel from TCS Destapes Industriales y Residenciales were recently seen addressing a sewage leak in the Tecnológico neighborhood. This reliance on external companies for routine maintenance has raised questions regarding whether SIMAS maintains the necessary resources and personnel to manage the city’s drainage needs independently. In response to infrastructure needs, Coahuila Governor Manolo Jiménez Salinas has announced significant state-level investments. The state government has allocated 155 million pesos this year to modernize the local wastewater treatment plant and improve essential services. ## Timeline ### 2026-08-27: Manolo Jiménez Salinas announces water infrastructure investment in Piedras Negras Coahuila Governor Manolo Jiménez Salinas announced 155 million pesos for drainage and water treatment infrastructure improvements in Piedras Negras, including a new pumping station. 3 sources. https://clstr.news/cluster/manolo-jimnez-salinas-announces-water-infrastructure-investment-in-piedras-negras ### 2026-08-24: SIMAS faces scrutiny over use of private contractors in Piedras Negras Private contractors were recently used to fix a sewage leak in Piedras Negras, raising questions about the operational capacity of the local water agency, SIMAS, despite claims of its recovery. 4 sources. https://clstr.news/cluster/simas-faces-scrutiny-over-use-of-private-contractors-in-piedras-negras ### 2026-08-21: Piedras Negras seeks 10.5 million pesos for hydraulic works Piedras Negras seeks to secure up to 10.5 million pesos for hydraulic infrastructure by incorporating municipal projects into CONAGUA programs before the October deadline. 2 sources. https://clstr.news/cluster/piedras-negras-seeks-105-million-pesos-for-hydraulic-works ### 2026-08-10: Piedras Negras Mayor proposes selling drainage services to Coahuila State Piedras Negras Mayor Jacobo Rodríguez proposed charging the Coahuila State Government for wastewater services to generate municipal revenue, a move facing potential legal hurdles. 4 sources. https://clstr.news/cluster/piedras-negras-mayor-proposes-selling-drainage-services-to-coahuila-state ### 2026-07-29: Piedras Negras faces water pressure drop amid tire‑recycling plant plans Piedras Negras' water utility will lower pressure overnight for valve repairs while the municipal government evaluates a tire‑recycling plant to cut landfill waste. 5 sources. https://clstr.news/cluster/piedras-negras-faces-water-pressure-drop-amid-tirerecycling-plant-plans --- Cite as: Piedras Negras water and waste management.
