Join Simple & Thames21 gather crucial data on the wet wipes settling on the Thames riverbed by getting down and dirty to count them!

Every time it rains in London, the sewers overflow which means the wet wipes that people flush down the loo end up the river. The problem is now so bad that hundreds of thousands are depositing on the river bed.

In order to say how bad the problem is, we are going to get as many people as we can to pick up all the wet wipes on the foreshore and record the final number.
