Infrastructure and water management efforts in Tamaulipas continue to evolve. While previous rains in May had significantly reduced drought conditions, recent monitoring indicates renewed water scarcity in several areas. Secretary of Hydraulic Resources for Social Development, Raúl Quiroga Álvarez, updated the Water Care Semaphore for 43 municipalities following the 27th Ordinary Session of the Evaluation and Monitoring Committee. Ten northern border municipalities, including Nuevo Laredo, Reynosa, and Matamoros, remain in the “red zone” due to low water levels in international dams. Ciudad Victoria and Tula are also categorized in the red zone. Conversely, the Guayalejo-Tamesí basin remains in the “green zone,” supporting municipalities like Tampico, Ciudad Madero, and Altamira, while the Soto la Marina and San Fernando basins are in the “yellow zone.” In Bustamante, officials are testing the El Caracol well to assist in reservoir filling. As of late August 2026, drought conditions have expanded to affect 51.7% of the Tamaulipas territory, according to the National Water Commission (Conagua). This includes 27 municipalities experiencing varying degrees of scarcity: 34.3% of the state is classified as “abnormally dry,” 15.3% faces moderate drought, and 2.1% is experiencing severe drought. Although some rainfall was recorded in early September, totals remain insufficient, and forecasted accumulations for mid-September are expected to remain well below historical averages. To address long-term agricultural needs, authorities have presented 2026 irrigation infrastructure projects. ~~These initiatives aim to modernize, rehabilitate, and technify irrigation systems to increase water-use efficiency.~~ Recent infrastructure developments also include a new water treatment plant in Ciudad Victoria designed to supply the ‘Guadalupe Victoria’ Aqueduct. Efforts to maintain existing systems are ongoing. In Altamira, COMAPA Altamira performed corrective and preventive maintenance at the DUPORT water treatment plant, servicing flocculation and sedimentation modules to ensure operational efficiency. Additionally, COMAPA Sur reported addressing more than 43,000 water and drainage leaks in Tampico and Ciudad Madero between 2023 and August 2026. ~~Officials attributed the high volume of repairs to the deterioration and age of hydraulic and sanitary networks.~~
