Welcome to the ACA's web site. We are a unique, non-profit making organisation that fights pollution and other damage to the water environment throughout the UK. Water pollution kills hundreds of thousands of fish each year, leaving a huge impact on aquatic wildlife and local economies, not to mention the enjoyment of all kinds of anglers. In addition, rivers and stillwaters face other threats such as water abstraction, escaped farmed fish, weirs and flood defence works. The ACA aims to stop this damage happening and fights for compensation for our members when it does.

We are usually fighting around 60 legal cases on behalf of our members at any one time. We make polluters pay hundreds of thousands of pounds in compensation every year and secure injunctions to stop further damage.

We can only do this with your support. If you care about the health of our rivers and stillwaters, then please join us. For as little as £2.00 per month you can contribute to the significant efforts we make to tackle the threats to our aquatic environment. For fishery owners and angling clubs that are not members, it is very difficult for us to act on your behalf if your water is damaged. For more details, including membership rates, see the 'Joining the ACA' section.

Please support our work. We can only make polluters pay with your backing.
