Innovation in pipe rehabilitation

The Secretariat of Comprehensive Water Management (Segiagua) has implemented the Tlaloque Reinforced operation, a strategy designed to optimize attention to the hydraulic network of Mexico City during the rainy season. As part of this initiative, the agency has acquired specialized equipment with ultraviolet technology, which makes it possible to repair leaks and rehabilitate pipes without the need for excavation. This technological advance not only reduces the urban impact, but also extends the useful life of the infrastructure to more than 50 years.

Technical details of the method

The process consists of introducing a sleeve pre-impregnated with resin inside the damaged pipe. Through the application of ultraviolet light, this sleeve solidifies, creating a new duct within the existing one. According to the owner of Segiagua, José Mario Esparza, this technique eliminates the need to remove pipes or open trenches, reducing costs and intervention times. In addition, the system is capable of rehabilitating up to 20 kilometers per year, with an investment that is recovered after repairing 1.5 kilometers, compared to the 20 million per kilometer that the traditional method costs.

Esparza highlighted that, although the equipment has a high initial cost (approximately 30 million pesos), its long-term profitability is unquestionable. The durability of the repairs and the minimization of urban disruption justify the investment, especially in a metropolis with constant challenges of aging infrastructure.

Impact and projection

This technology not only optimizes public resources, but also aligns CDMX with global sustainability practices. By avoiding excavations, CO₂ emissions associated with heavy machinery are reduced and public space is preserved. Segiagua’s approach reflects a growing trend in hydraulic engineering: less invasive and more efficient solutions, capable of adapting to complex urban environments.

The project is part of a comprehensive strategy that includes the launch of hydropneumatic trucks and other specialized vehicles for emergencies during the rainy season. With these actions, the city is moving towards a more resilient and technical water management model.

SEP reiterates ban on military education

The Ministry of Public Education (SEP) stated that education under military or military modalities is not permitted in Mexico. The statement came after the death of a teenager at a summer camp with military characteristics in Ciudad Madero, Tamaulipas.

The head of the SEP, Mario Delgado Carrillo, condemned attempts to justify acts of violence or mistreatment with the argument of a supposed military education. He pointed out that these practices are not training methods and violate the human rights of children and adolescents.

Through a statement, the agency clarified that no basic education institution is authorized to teach teachings labeled as military or military. He explained that military education is exclusive for personnel of the Armed Forces and the National Guard.

Regarding the incident, state educational authorities will take measures to protect the rights of minors. According to family testimonies, the teenager entered the camp on July 13 in good health and days later she was reported fainted after a fall. The minor died inside the facilities.

The SEP reiterated its rejection of any practice of abuse or degrading treatment against minors. The case has generated a call to review supervision mechanisms in extracurricular activities.

President Claudia Sheinbaum reported that the United States will resume importing Mexican cattle starting the last week of August. The decision came after an official communication from the US Secretary of Agriculture, Brooke Rollins.

Reopening schedule

The reopening will begin at the border port of Agua Prieta, Sonora, linked to the Douglas crossing, Arizona. August 24 will be the first date of operation. Later, two additional points will be enabled in Chihuahua, subject to compliance with the Joint Action Plan against screwworm.

Sheinbaum instructed federal agencies to accelerate coordination with US authorities. He highlighted the work of the Secretary of Agriculture, Julio Berdegué, and the director of Senasica, Columba López, to strengthen health measures.

The animals will enter with complete inspections to verify that they do not show signs of the plague.
Later, the opening of the ports of Santa Teresa and Columbus, in New Mexico, will be evaluated.

The president described the news as positive for Mexican ranchers, who for months contained the spread of the screwworm. He appreciated Rollins’ willingness to maintain an institutional relationship.

Rollins, for his part, stated that the protection of the US livestock industry remains a priority and that the temporary closure of crossings was necessary to reduce risks. The reopening is possible thanks to binational collaboration.

Operational in the port of Manzanillo

Federal authorities seized more than eight million allegedly apocryphal cigarettes in the port of Manzanillo, Colima. The operation was coordinated by agencies of the security cabinet and the National Customs Agency of Mexico (ANAM).

Personnel from the ANAM and the Administrative Unit of the Manzanillo Customs detected inconsistencies in an operation to import cigarettes from abroad. This led to a specialized review.

As a result of the inspections, the authorities located 8 million 436 presumably counterfeit cigarettes. The merchandise was insured with the support of the Secretary of the Navy (Semar).

The ANAM reported that this type of operations are part of the permanent mechanisms of operational intelligence, risk management and strategic analysis. The objective is to strengthen security in foreign trade operations and detect documentary irregularities or goods of illicit origin.

The comprehensive analysis of the operation made it possible to reinforce documentary traceability, operational review and validation of commercial profiles. The authorities maintain surveillance at entry points into the country to combat illegal trade.
