They reported that they are in phase one of the construction of a provisional collector that is located six meters deep, with a 200-meter-long pipe that seeks to channel rainwater from surrounding neighborhoods. and avoid complications in the construction of the definitive collector.
The community added that the temporary pipe being installed is 42 inches in diameter, while the one that collapsed has 72.
The commune ensures that with the definitive collector the use of another type of pipe and measures will be evaluated, since the water it carries is greater than what the collapsed one supported. The works on the Calzada Concepción could last the rest of the year, due to the studies and because a 450-meter collector will be built.
Until now They do not have defined costs or exact execution time.
