Water Regulation

Water quality regulation

The Environment Agency regulates a wide range of activities and operators. One of the industries we regulate is the water industry and our activity includes permitting, compliance and enforcement. We have a key role alongside many others, including farming and wider industry to protect and improve water, now and in the future.

Over recent years, our regulation has contributed to major environmental improvements, but we face new pressures and urgent challenges in the rapidly changing world around us. Our regulation(External link) will protect and improve the environment.
