Access to water is a fundamental human right that is crucial to poverty reduction. It is also one of the eight Millennium Development Goals.


The lack of potable water in indigenous communities drastically limits their opportunities for economic development, leaving only extractive activities detrimental to the ecosystem and the long-term survival of these communities as main sources of income.


Entropika’s water project aims to improve access to clean drinking water, basic sanitation and hygiene in indigenous communities, schools and marginal neighborhoods of Colombia and Peru through the implementation of alternative water filtration technologies, while empowering target groups in their use and maintenance.

The project current benefits around 12.500 people in three regions, each of which face their own unique challenges


Located along the banks of the Amazon River (17 in Colombia and 7 in Peru), and 5 schools and 1 orphanage in Leticia, capital of the Colombian Amazon. Approximately 6,500 people in this region benefit from this initiative.


In the marginalized neighbourhood of "El Granizal", located in the suburbs of Medellin, the second biggest city of Colombia, we have 328 micro-membrane filters operating in homes, schools and community centers, benefiting around 5,250 people.


In the Wayuu indigenous community of Paraíso, Riohacha, La Guajira (an arid region to the north of Colombia), a solar-powered reverse osmosis treatment plant benefits approximately 750 people.

A network of local water coordinators trained in the installation, maintenance, and use of the filters has been set up in each one of these regions in order to make sure they are used correctly by the beneficiaries and so they will last in the long-term.


Entropika’s water team also regularly visits the communities, schools, and marginalized neighborhoods; these visits are carried out once a month in the Amazon and every three months in Medellin and La Guajira. 

The water project has improved the health of indigenous communities and vulnerable neighborhoods where it has been implemented by reducing water-borne diseases that cause vomiting and diarrhea and raises local awareness on the importance of having access to clean water, basic sanitation, and education.


These results also amplify the impacts of Entropika’s line of work to improve access to education (see link to project) since a student who is ill cannot attend classes or dedicate time to studying.


These interventions have received attention from the local and national government, as well as international NGOs, and will continue to expand to more Tikuna and Wayuu indigenous communities of the Amazon and La Guajira, as well as to other marginalized neighbourhoods of Medellin.
