Emcali activated permanent monitoring on Friday, April 17, due to increased turbidity in the Cauca River from recent rains dragging sediments. The issue impacts water intake at the Puerto Mallarino plant, Cali's main treatment facility. The company is using reservoirs to maintain supply, but warns of possible low pressures in some areas.
The rise in Cauca River turbidity prompted Emcali to enact operational measures in Cali. Regional rains caused sediment drag into the river, hindering intake at the Puerto Mallarino plant.
The public utility conducts ongoing monitoring of water quality and adjusts treatment processes based on river conditions. Reservoirs enable continued aqueduct service without widespread interruptions in the city.
Emcali warned, however, that areas at the end of the distribution network, such as Bochalema, may experience pressure variations. Homes without storage systems could face temporary challenges.
Technical staff oversee the plant and network to promptly address issues, focusing on supply stability until river conditions normalize.
