Peru’s Pacific hydrographic region is home to more than 55% of the country’s population but holds less than 2% of its freshwater resources.¹ Household access also depends on where utilities extend their networks and how they manage the water supply.²

From July 2025 through June 2026, 90.6% of households in Peru obtained water through the public network. Among those households, water was available for an average of 124 hours per week.³ This ongoing research examines how three aspects of water access vary across Lima, Piura, and Arequipa: what households pay for water, how many hours water is available, and how much time residents spend collecting it.
