Water rights and usage in Costa Rica

Costa Rica is a beautiful country in Central America, famous for its stunning beaches, lush rainforests, and rich biodiversity. It is also home to a unique system of water rights that has been in place for over a century.

The concept of water rights in Costa Rica dates back to the early 1900s when the country established a national water authority, known as the Costa Rican Institute of Aqueducts and Sewers (AyA). The AyA was created to manage the country’s water resources and ensure that all citizens had access to clean drinking water.

One of the unique aspects of Costa Rica’s water rights system is that water is considered a public good. This means that the government owns all of the water resources in the country, and citizens and businesses must obtain permits from the AyA in order to use them.

The AyA is responsible for granting permits for the use of water resources, including for domestic, agricultural, and industrial purposes. The permits are typically issued for a set period of time, and the AyA has the power to revoke them if the water user violates the terms of the permit or if there is a shortage of water in the area.

Another important aspect of Costa Rica’s water rights system is the concept of “priority use.” This means that certain types of water use, such as domestic use and small-scale agriculture, are given priority over other uses, such as large-scale agriculture or industrial use. This ensures that all citizens have access to clean drinking water and that small farmers are not pushed out by larger corporations.

In recent years, Costa Rica has faced some challenges related to water rights. Climate change has led to more frequent droughts, which has put pressure on the country’s water resources. Additionally, some businesses have been accused of using water resources without proper permits or in ways that violate the terms of their permits.

Despite these challenges, Costa Rica’s water rights system remains a model for other countries. The government has taken steps to improve the management of water resources, including investing in new infrastructure and technology to monitor water usage. As a result, Costa Rica continues to be one of the most environmentally friendly and sustainable countries in the world.


In Costa Rica, ASADAS are community-based organizations responsible for managing water resources and providing access to clean drinking water for their communities. The acronym “ASADAS” stands for “Administración de Servicios de Agua y Saneamiento,” which translates to “Administration of Water and Sanitation Services.”

ASADAS were established in the 1970s as part of a government effort to decentralize water management and involve local communities in the process. Today, there are over 2,500 ASADAS in Costa Rica, serving both urban and rural areas.

Each ASADA is governed by a board of directors, made up of community members who are elected by the members of the organization. The board is responsible for managing the ASADA’s finances, making decisions about water usage, and ensuring that the community has access to clean drinking water.

ASADAS are funded through a variety of sources, including government grants, user fees, and donations. The fees charged by ASADAS are generally lower than those charged by the national water authority, AyA, making them more accessible for low-income communities.

In addition to managing water resources, ASADAS also play an important role in environmental conservation. Many ASADAS work with local conservation groups to protect the rivers and streams that provide their water supply, and some even offer ecotourism activities to raise funds for their operations.

Overall, ASADAS are an important part of Costa Rica’s water management system, providing local communities with access to clean drinking water and promoting sustainable water use practices.
