OOMSAPAS repairs El Carrizal aqueduct and restores water in southern La Paz

The utility replaced two pipe sections damaged by the rains; service is returning gradually to neighborhoods such as Camino Real, La Fuente and Valle del Mezquite.

OOMSAPAS crew repairs El Carrizal aqueduct pipeline in La Paz

La Paz's water utility restored operation of the El Carrizal aqueduct after replacing two 18-inch pipe sections —12 meters in total— that were damaged by rains and rising stream runoff in the area. With the repair finished this week, supply began recovering across the southern part of the city.

According to OOMSAPAS La Paz, the failure knocked eight wells in the El Carrizal and San Pedro systems out of service, cutting between 20 and 25 million liters of water per day, roughly 20 percent of the municipality's total supply. By the weekend, 95 percent of those wells were operating normally again.

The neighborhoods hit by the shortage sit in the southern part of the city and are fed from the San Ramón tank: Camino Real, Ayuntamiento, La Fuente, Valle del Mezquite and adjacent sectors. The utility's general director, Abimael Ibarra Abúndez, said the system had recovered enough flow and volume, and that the network would stabilize gradually as tanks and pipes refill.

Normalization is not instant: water returns through the usual rationing (tandeo) cycles, because storage tanks and the distribution network must recharge before pressure reaches each block. As a result, in the hours after service is restored some homes may still receive water intermittently.

This kind of damage has become common during the rainy season, when arroyos swell and drag material that strikes exposed water infrastructure. The El Carrizal aqueduct is one of the key supply lines for southern La Paz, which is why a break at that point is felt across several neighborhoods at once.

While service stabilizes, residents should store water in clean, covered containers, prioritize it for hygiene and drinking, and avoid waste. Users who spot leaks, dry taps or prolonged low pressure can report it to OOMSAPAS La Paz so a crew can be dispatched; having your account number ready speeds up follow-up.
