La Paz’s municipal water utility discovered at least five unauthorized pumps and multiple illegal water connections in the Cola de la Ballena neighborhood, blaming them for pressure drops across the local distribution network.
OOMSAPAS (the Municipal Drinking Water and Sanitation System of La Paz) launched the inspection after residents posted complaints on social media about low water pressure. Director Abimael Ibarra Abundez confirmed the findings and said crews will return this week to cut the illegal connections, install meters, and fine violators.
How Illegal Taps Drain the System
Unauthorized pumps attached directly to the water main pull water at higher rates than the system was designed to deliver. That drops pressure for legitimate users on the same line, sometimes reducing flow to a trickle in homes farther from the source. The problem is not new in La Paz. In March 2026, OOMSAPAS launched a broader regularization campaign under the slogan “Goodbye to water theft,” aiming to fold unauthorized users into the official billing system.
Illegal connections have been a chronic issue in the city. Many were originally installed by housing developers who sold homes without formal water contracts, leaving buyers receiving service they never registered. Less than 25% of residential and commercial buildings in La Paz have water meters, according to local conservation groups, giving users little economic reason to conserve.
Enforcement and What Residents Should Know
OOMSAPAS crews plan to audit water contracts in affected areas this week. Residents with legally installed booster pumps should have their utility contracts available for inspection. Those found with unauthorized connections face fines and disconnection.
The crackdown comes as La Paz already operates under scheduled water rationing, or “tandeo,” that limits service hours in many colonias. Illegal taps compound the rationing problem by diverting water that the utility has already allocated to specific zones and time slots. For the remainder of 2026, OOMSAPAS expects the flow recovered from cutting illegal connections to allow extended service hours in parts of northern and southern La Paz.
La Paz depends on groundwater and a 40-kilometer aqueduct from El Carrizal for its drinking water supply. With the aquifer under long-term stress, officials say every unauthorized connection accelerates the gap between supply and demand.
