This pledge to walk 1, 2 or 4km every day to give people the power to change their own lives, forever. Join us and walk for the millions of women and children who walk distances like this every day to get the water they need to survive.

Clean water, decent toilets and good hygiene are basic human rights. They should be a normal part of daily life for everyone, everywhere – but they aren't. That's why we're here. Only by tackling these three essentials in ways that last can people change their lives for good.
