New treatment provides hope for £2m a year zebra mussel menace

Many water and sewerage companies are experiencing problems with zebra mussel infestations, according to a survey by ENDS. But a new treatment has given hope to firms, which spend more than £2m a year on cleaning clogged pipes and water treatment work intakes (see table).

Only Scottish, Northumbrian, Wessex, United Utilities and South West are not having problems with the invasive species.
