A landslide in the La Mica region, located southeast of Quito, Ecuador, caused severe damage to the La Mica-Quito Sur pipeline at around 23:00 LT on July 9. The rupture affected 350 m (1 150 feet) of 1 m (3.2 feet) steel pipeline, which serves as a critical conduit for potable water to the southern districts of the city.
Six parishes, Guamaní, La Ecuatoriana, Chillogallo, Argelia, Quitumbe, and Turubamba, were left without water, impacting an estimated 88 707 families or 400 000 individuals. The landslide occurred 10 km (6.2 miles) from the reservoir intake point and followed days of persistent rainfall that destabilized the surrounding terrain.
On July 10, Quito’s municipal emergency operations committee (COE-M) declared a water emergency. Authorities mobilized over 60 tanker trucks, 4 inflatable cisterns each holding 25 m³ (890 square feet), and portable water stations, prioritizing service to hospitals, health centers, educational facilities, markets, and vulnerable communities.
Approximately 120 000 m³ (4.24 million square feet) of material was displaced by the landslide, according to municipal sources. Removal operations have been ongoing using heavy machinery in the affected zone.
To repair the rupture, the Empresa Pública Metropolitana de Agua Potable y Saneamiento (EPMAPS) sourced over 300 m (984 feet) of high-density polyethylene (HDPE) piping from Cuenca to replace the damaged steel section. Installation of replacement infrastructure began between July 14 and 17, with expedited logistics implemented due to the scale of the emergency.
Security forces were deployed to monitor water distribution points and prevent illegal resale or hoarding of tanker-supplied water. Coordination between Quito’s municipal government and the National Risk and Emergency Management Service of Ecuador (SNGRE) continues to monitor the situation and ensure the integrity of the remaining pipeline network.
