Costa Rican Government Laws & Regulations

There are four institutions in charge of the responsible management of water resources in Costa Rica:

  • the Ministry of Environment and Energy (MINAE)
  • they are responsible for control and management of national water resources
  • the Ministry of Health (MINSALUD)
  • they are responsible for water including pollution control 
  • the Ministry of Agriculture and its department the National Groundwater, Irrigation and Drainage Service (SENARA)
  • they are responsible for soil conservation and groundwater management, and 
  • the National Institute of Aqueducts and Sewers (AyA)
  • they are Costa Rica’s PUBLIC water and sewage utility agency and are responsible for the supply of drinking water and sanitation.

Ground and surface waters are publicly owned. Legislation regulating the right to abstract water includes:

  • Water Law No. 276 of 1942;
  • Executive Decree No. 35884- MINAET 2010 (Drilling Regulations for Subsurface Exploration and Exploitation of Groundwater);
