We dropped leaflets through the doors of the houses in the roads around our chosen stream so that people knew what we were doing.
We then stencilled a yellow fish next to the drains in the roads with spray paint, as a reminder.
Some people asked us what we were doing as we went along the road so we gave them leaflets and talked to them about it.
They all thought it was a very good idea.
Before being involved with the Yellow Fish project I hadn't even thought about where anything poured down a drain would go, nor had my family.
We are now much better informed about this, and will continue to tell other people because it is important.
There are places to dispose of oil, paint etc, and that place is not down our drains!
I would really recommend that people get involved with this project, it's fun and worthwhile."
