Aguas Andinas replaced 0.2% of its drinking water pipes in 2025, according to its integrated report for that year. At that pace, renewing the whole network would take about 500 years, even as the company's leak detection and metering programs expand.
Detection is improving
The company's infrastructure leakage index fell from 48.4 in 2021 to 43.2 in 2025, and unrecorded water across the group dropped from 234.65 hm³ in 2024 to 215.14 hm³ in 2025. Robotic inspection has diagnosed 65% of the aqueducts that carry water across Santiago.
In 2025 Aguas Andinas also launched programs to measure what it could not see: H2O Verde to standardize meter readings at 8,470 green-space locations, Hunter Meter for real-time monitoring of key customers, and Fuga 0 Social to repair hidden leaks in low-income homes.
Losses remain high
Total losses, measured from tank inlet to billing, were 28.3% in 2025, down from 29.4% in 2024. Real losses in the distribution system still made up 21.8% of the water entering the tanks.
Plans and results diverge
The company's May 2026 corporate presentation lists 0.5% annual network renewal from 2024 as an investment item, and its FY 2024 report gave 0.5% for the network as a whole. The FY 2025 report puts drinking water pipe replacement at 0.2% and wastewater pipe replacement at 0.5%. Network renewal is funded through Chile's five-year tariff process, which for 2025 to 2030 also carries a 7.4% tariff for drought and climate works.
How Aguas Andinas' digital programs, groundwater build-out and works tariff fit together, and which renewal and resilience measures to track through 2027, are set out in the full report.
