Phase: Phase 4: Action Plan

Institutions: The Costa Rican Water and Sanitation Institute (AyA)

Sector: Water and Sanitation

Public Policy : National Program for Risk Reduction

Countries: Infrastructure Institutional Program


The Costa Rican Water and Sanitation Institute (AyA), aware of the needs to have disaster risk related information of the country’s infrastructure, requested the support from The World Bank to build technical and institutional capacity across the agency, as well as to develop probabilistic seismic risk models for some of its water and sanitation infrastructure in San Jose greater metropolitan area, San Isidro and Higuito, that together serve more than 2.7 million people.

Under the Technical Assistance Project (TAP) approach, The World Bank delivered hands-on, practical training programs and provided an opportunity for AyA to lead the seismic risk assessment process and take ownership of the results. The risk assessments delivered critical information about the most vulnerable assets and areas that may concentrate higher economic losses. This information can now inform decisions about infrastructure investments and emergency preparedness to avoid disruptions in water and sanitation services in the event of an earthquake. In addition, AyA is now capable of replicating these studies for other water and sanitation infrastructure of the country.
