The campaign aims to make sure that by the end of the summer 134,000 people in some of the poorest communities in rural Malawi get access to clean water.
The campaign is really interesting as it will supported by live blogging and Instagram via smartphone from two of WaterAid's staff on the ground in Malawi. We will see the success of the campaign, as it happens, through the eyes of the communities being helped.
And to make things even better, every gift before the 18th September is matched by the government.
You can get involved here.
I love the thinking behind this campaign and wish it all the success in the world.
