Great British Water Project

Welcome to the Great British Water Project, a nationwide, interactive experiment organised by the Don Hanson Charitable Foundation to study the quality of tap water across the United Kingdom and the health of the country’s freshwater habitats.

Over June and July, 2021, Great British Water Project resource boxes were sent to 650 schools across the UK to enable students to take part in a range of interactive experiments and activities.

On August 11th 2021, the results of the Great British Water Project were announced. Watch the following summary film to discover what the schools and students across the UK found out:

Below are the results received so far. The results of each experiment and activity are displayed as an interactive map. I can link on any of the filter terms (at the top of each map) to display results.  

Note the key to the left of email map to explain the colouration of each marker icon.  Click on each icon for data to be displayed! 

Note to schools that have received the great British Water Project resource box – please do continue to send your data sheets across. We will add your data to the following results spreadsheets, so you can discover how your findings compare nationally!
