The “Coastal Niño” Phenomenon of 2017 caused rains and floods that affected 1.7 million people in Peru. Piura was one of the most affected departments. In the Pedregal Chico and Pedregal Grande (Catacaos, Piura) settlements, the sewage systems collapsed after the floods.

The intervention sought improved access to water and sanitation services and hygiene practices for 400 families in Pedregal Chico and Pedregal Grande, actions aligned with UNICEF’s WASH (water, sanitation and hygiene) program.

After preparation of a diagnosis, the project identified measures to improve water and sanitation services, based on the needs of each locality.

In Pedregal Chico, for example, the project focused on delivering 100-liter water tanks and on the construction of home toilets. In Pedregal Grande, where the sewage system had collapsed, temporary multi-family sanitary latrines, water points for hand washing and 100-liter water tanks were installed, and work was done in coordination with community actors and the Municipality of Catacaos to strengthen their capacity to monitor the works.


  • Improved access to safe water in the affected communities of Catacaos and Cura Mori.
  • Improved access to sanitation for families in affected areas through the implementation of context-appropriate solutions.
  • Provide families access to information on proper hygiene practices and vector control through the strengthening and training of hygiene committees and promoters.


  • 318 families received water containers for use in flush toilets.
  • 130 families have access to improved drinking water service.
  • 382 families have access to functional and adapted latrines.
  • 417 families receive information on hygiene practices.
