Tap's profits fund water projects in the developing world and there's lots of great ideas out there. Read on to see the kinds of projects we're looking to support - and click on the links to find ways of supporting them yourself.
Ryan Hreljak is from Canada and has been building wells in Africa since he was 6 years old. Now 16, his foundation, Ryan's Well, has built over 300 wells in 14 countries and provided access to clean water for half a million people.

Many women and girls walk 5 kilometres to find water, carrying back 15-litre containers on their heads. A simple solution has been developed in South Africa which is known as the Water Hippo. Similar to a garden roller, the tank is filled and rolled back to the village, enabling women to collect five times as much water on each trip. Who knew hippos could be so helpful?

One of the biggest challenges is how to get underground water lifted to the surface. Play Pumps International has created a "magic roundabout" where the merry-go-round powers a pump as the children ride it.

Another solution to raising underground water is a treadle pump developed by International Development Enterprises, which involves a sort of stationary bicycle to lift the water. Cycling nowhere was never so useful.

The Barefoot College in India is now providing training in Africa so that villagers can install rooftop collection systems where rainfall is insufficient to meet their daily needs. They're gutters for good.

Access to clean, sanitary water is a matter of life or death for millions of people. Life straw is a simple filtration system contained in a straw through which people drink their water. It's sucking for life.
