Overview
- ERAS published Resolution 41/2026 and scheduled a virtual public hearing for October 26 to examine AySA’s technical proposal and mitigation measures.
- AySA says the change would raise its revenues by 7.3 percent, about $140.057 billion in September 2026 values, and that all excess recaipts would be directed to the Programa de Tarifa Social.
- The company estimates 55–60 percent of users would pay more, with average increases around 22–23 percent for affected households, while about 20 percent would see cuts and 20–25 percent no change.
- To limit shocks AySA proposes phased measures that cap increases at 5 percent monthly until full adjustment and remove the existing 15 percent low-zone discount in three staged steps.
- The proposal updates a zonal scheme not overhauled in more than 40 years using Census 2022 and EPH data, assigns higher coefficients to gated developments and lower ones to informal settlements, and adds a 10 percent sewage surcharge for Buenos Aires’ Radio Antiguo.
