SUPPORTING WATERAID
Because we truly care about sanitation
Almost 2 billion people do not have a decent toilet or access to basic and safely managed sanitation. In many cases, faeces and urine end up untreated in the environment, contaminating it and threatening people’s health.
This is why IER supports WaterAid programs, to facilitate access to safe water, sanitation and hygiene in the world’s poorest and most marginalised communities.
