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.

Along with our parent company, Calix (calix.global), we work cooperatively with each other, our team, our customers, and partners worldwide, to make a positive difference for the long-term. Because there is only one Earth.

Mars is for quitters!
