Authorities have launched a large-scale cleaning operation along key waterways in Asunción to prevent flooding in vulnerable neighbourhoods. The work focuses on the Arroyo Morotí and the mouth of the Arroyo Ferreira. Officials say the effort could protect more than 21,000 residents living in densely populated areas. The preventive measure responds to seasonal risks linked to heavy rainfall and blocked channels.
Reducing risks with waterway cleaning
Cleaning work began this week along the Arroyo Morotí, located near the Costanera Norte. The operation aims to stop both waterways from overflowing during periods of heavy rain. Authorities estimate that flooding could affect more than 5,400 homes in the neighbourhoods of Santa Ana and San Cayetano. These areas are among the most exposed to water surges in the capital.
Arsenio Zárate, Minister of the National Emergency Secretariat, explained that the goal is to reduce risks before emergencies occur. According to officials, sediment accumulation has already limited the flow of water. In addition, waste disposal along the stream has worsened the situation. As a result, blockages can quickly form during heavy rainfall.
Zárate noted that the work targets areas where invasive vegetation has grown heavily. Plants such as castor bushes and water hyacinths reduce the waterway’s capacity. Consequently, even moderate rainfall can cause streams to overflow. Clearing these plants will help restore normal water flow.
Prevention as a long-term strategy
Authorities emphasise that prevention remains more effective than emergency response. Early action can reduce potential public spending by up to 10%. Moreover, protecting homes helps prevent displacement and property damage. For many families, flooding has been a recurring concern for years.
The cleaning will continue until the Arroyo Morotí channel is fully cleared. Teams will also remove obstructions from the mouth of the Arroyo Ferreira. Officials believe that sustained maintenance will lower flood risks in the future. The initiative represents an important step towards safeguarding thousands of residents in Asunción’s most vulnerable communities.
