A scheme to raise awareness about sources of water pollution and the quality of water in your local streams, rivers, lakes or ponds.
What is the Yellow Fish scheme?
Yellow Fish is very simple. It raises awareness with an enjoyable and low cost activity to support our message – Only rain down the drain!
Drains are marked using the Yellow Fish stencil and awareness raised locally to help prevent diffuse pollution. We will record your project location on our national Yellow Fish map and if you can get media coverage, all the better!
Yellow Fish promotes awareness of local environments, diffuse pollution and the quality of water in your local stream, river, lake, pond, canal, beach or break. Anything going down drains will ultimately end up entering watercourses and the sea. Pollutants such as oils, paints, chemicals, dirty water, and even litter entering drains can seriously impact upon your local watercourse or seaside. It also raises awareness of misconnections, which result in sewage and grey water entering your rivers.
