Conservationists are working with Enfield Borough Council to improve the quality of a stream in the area.

Sewage has blighted the Grovelands Park stream for years with the water quality harmful to humans and animals.

However, conservation charity Thames21 is now working with the council to rid the stream of sewage by rerouting the stream away from waste pipes.

The charity will also be adding new water cleansing system to filter pollutants out of pipes that are misconnected from houses into the stream.

Thames 21 worker Aimee Felus said: “Up to ten per cent of homes in London are misconnected, unknowingly polluting their local waterway.  This combined with chemicals being washed off roads means that most of our urban rivers are in trouble.

“It’s Thames21’s hope that other London boroughs will follow this example and improve their waterways as well. We are more than happy to assist any London borough in installing Sustainable Drainage Systems around their rivers, lakes and streams in order to improve the quality of London’s waterways.”

Earlier this year, Enfield Independent revealed that other streams and lakes in the borough had also suffered from misconnected waste pipes causing alarming levels of pollutants to be found.
