New wetlands set to protect river from pollution

The Chamber Mead wetlands are a "critical pollution buster" for the River Hogsmill, says the South East Rivers Trust

A new wetlands in Ewell in Surrey will naturally protect the River Hogsmill and ultimately the Thames from pollution, says the South East Rivers Trust.

Road run-offs, sewage pipes and storm discharges adversely affect water quality in the area.

The trust says the Chamber Mead wetlands will conserve the chalk stream and help the area become a haven for brown trout, water voles, native crayfish and other wildlife.

An open day on 20 April will offer people the chance to learn more about the wetlands' environmental role.

They will also be invited to plant their own pollutant-absorbing plants.
