The smell produced by Mogden sewage treatment works is something that has affected many local residents over the years; sometimes so badly that windows have to remain closed and summer BBQs abandoned.
In July 2001, after numerous complaints from local residents, we took the first steps to tackle this problem and served an odour abatement notice on Thames Water.
It was only seven years later, and after a long legal challenge, that Thames Water finally agreed to comply. Despite this action, it was clear that the problem hadn’t been solved.
Earlier this year, we received an application to extend the site so that the government’s new urban waste water treatment directive could be complied with.
Planning permission was granted on the condition that the Mogden works would comply with strict conditions aimed at reducing the smells and keeping residents informed.
