Explanation


SamSamWater makes information on water and sanitation easy to find and accessible for all. This page contains a database with practical information, data and (GIS)maps.

We believe information should be shared to make water and sanitation projects more successful. The information in the database is gathered from numerous sources, such as research institutes, companies, NGOs and government organisations.

Do you have information we can integrate into this database, or if you have comments or questions, please contact us!
