La Paz’s municipal government is building three elevated water tanks across the city’s expanding neighborhoods, a 41.7 million peso ($2.3 million USD) investment that officials say will improve water pressure for roughly 19,000 residents.
The projects are spread across three colonias on the city’s outskirts. The largest, in the Diana Laura neighborhood, is a 250 cubic meter elevated tank that is 98 percent complete. It cost 14.7 million pesos ($817,000 USD) and will serve 15,603 people, according to the La Paz municipal government. A second tank in Paraíso del Sol, also 250 cubic meters with an additional 100 cubic meter ground cistern, is 97.5 percent complete at a cost of 15 million pesos ($833,000 USD) and will benefit 1,300 residents. The third, in the La Pasión neighborhood, is a 150 cubic meter tank with a 50 cubic meter cistern budgeted at 12 million pesos ($667,000 USD), serving 2,103 people.
All three use a gravity-feed design: water is pumped into elevated tanks, then flows downhill to homes, maintaining consistent pressure during peak demand hours without requiring individual households to run their own pumps. La Paz already uses this system in the Indeco and Fidepaz neighborhoods, where residents have reported improved pressure after similar tanks were installed.
Low water pressure is a familiar headache for anyone who has lived in La Paz’s outlying colonias. Many homeowners rely on rooftop tinaco tanks and electric pressure pumps just to get a usable shower. The problem worsens during summer, when demand spikes and the city’s aging distribution network struggles to push water uphill to newer developments.
These three tanks are part of a much larger water infrastructure push in La Paz. Mexico’s national water commission, CONAGUA, broke ground last year on the El Novillo dam about 30 kilometers east of the city. That project includes a 15 kilometer aqueduct and 22 elevated storage tanks designed to overhaul the distribution system for the entire urban area, which serves roughly 250,000 people. The El Novillo system aims to reduce La Paz’s dependence on its overdrawn aquifer, which has shown increasing salinity from seawater intrusion in recent years.
For expats and property owners in La Paz’s growing residential zones, the immediate takeaway is practical. Once the Diana Laura and Paraíso del Sol tanks come online in the coming weeks, residents in those neighborhoods should see steadier water pressure, particularly during morning and evening peak hours when the system is under the most strain.
