Sunass Approves Water Tariff Hike in Lima and Callao, 12% for Homes and Up to 20% for Businesses From February

The regulator says the rebalancing mandated by Legislative Decree 1620 will cover real service costs, with stricter oversight to verify measurable improvements.

Overview

  • The adjustment begins to apply in January, and users will first see the higher charges on bills issued from February 2026.
  • Sunass set tiered domestic rates per cubic meter at S/2.20 (0–10 m³), S/2.36 (10–20 m³), S/3.22 (20–50 m³), and S/7.32 above 50 m³, with a first‑tier social rate of S/1.92 in Punta Negra, Punta Hermosa, San Bartolo, and Santa María del Mar.
  • Non‑residential users face higher bands, with commerce at S/8.82 per m³ up to 1,000 m³ and S/9.46 above that, industry at S/9.46, and state entities at S/5.80.
  • Sedapal said it will comply with the regulator’s decision, while the National Society of Industries called the increase disproportionate, cited 2025 inflation of about 1.5%, and alleged interference by the Housing Ministry.
  • Sunass said the process included a published proposal, a public hearing, and a comment period, and it estimates a household using 16 m³ a month will pay about S/7.70 more per bill.
