Why (Treated) Tap Water is the 

Solution ?

Tap water is the highest rung on the access to water ladder, because it is...



...convenient and

...a proven solution

with 3.5+ billion people

using tap water globally

Talking in SDGs

                    (Sustainable Development Goals)

much more than

Tap water is

Goal 6: Ensure access to water and sanitation for all

Target 6.1 By 2030, achieve universal and equitable access to safe and affordable drinking water for all.

Indicator 6.1.1 Proportion of population using safely managed drinking water services.

Reflecting on our Impacts

As a social enterprise, we are committed to carefully measure, from 2020, the impacts of our solution on the communities that we serve. This phase of assessment is pivotal  to optimise the benefits and allow for incremental improvements.
