A storm overflow releases diluted sewage into a river or the sea when sewers are overloaded, usually in heavy rain. Hours are the total time all spills lasted. Spills are counted the Environment Agency’s way: any discharge in the first 12 hours counts as one spill, and each further 24 hour block counts as another. Compare every council, constituency and water company.
