The Deep aquarium in Hull, UK, has teamed up with Thirsty Planet water and charity Pump Aid.

So far, staff and visitors to the attraction have helped to provide 38.5 million gallons of clean, disease-free water for some of the poorest people in Africa through sales of Thirsty Planet in The Deep's cafe and restaurant.

For every 500ml bottle of Thirsty Planet that is sold, a donation of 5p is made to Pump Aid, which works with rural communities in Malawi and Zimbabwe to give them access to sustainable supplies of uncontaminated water.
