Overview
- Residents across Piura, Castilla and Veintiséis de Octubre reported bills that jumped from about S/40–50 to several hundred soles, with cases up to S/489.
- Long lines formed at EPS Grau as customers filed complaints, with many saying they pay for water that arrives only for limited hours.
- EPS Grau said Sunass approved tariff increases of 12.4% in September 2025 and 12.8% in March 2026, which raised prices.
- The utility installed about 24,000 new meters toward a 37,000 goal after years of flat-rate billing and old devices last replaced in 2017.
- EPS Grau argued high readings reflect real use or hidden leaks, offered a one-time bill cut if users fix a verified leak, and said new meters passed initial tests while warning against illegal meter tampering.
