Water Service Requests - Requisitos para servicios de agua

Obtaining a Water Letter from the LDM ASADA

All properties in Costa Rica get water from either an ASADA or AyA, the national water suppliers. You must ask for a water letter to show there’s drinkable water on your property. You do this by applying to the LDM ASADA and provide key documents.

Validity Period and Renewal Process

The water letter is valid for 6 to 12 months. You must start building within this time to avoid issues. In some places like Guanacaste, renewing the letter might be tough because of water shortages. If it expires, your building plans could be delayed.
