Summary and headline written by AI from the source article. How we work

The Autoridad Nacional del Agua (ANA) is installing 12 flexible steel dynamic barriers in vulnerable areas of Lima Metropolitana and Huarochirí to prepare for the upcoming rainy season.

Workers finished installing the barriers in Huayaringa and Cupiche. Construction continues in La Ronda, Señor de los Milagros, Cashahuacra 1, Cashahuacra 2, and Quirio. The agency is also moving forward with the implementation of structures at five other locations.

These barriers are placed in critical points such as Lurigancho-Chosica, Cieneguilla, and Chaclacayo in Lima Metropolitana, as well as Santa Eulalia and Ricardo Palma in Huarochirí. The ANA says these structures will protect more than 120,000 residents by reducing the impact of huaicos, which are mudslides triggered by heavy rains. The barriers are designed to contain and mitigate debris flows that can damage homes, roads, basic services, and productive zones.

The agency urged the public to follow official recommendations during periods of intense rainfall.
