Mogden sewage works

We know that many local residents have been affected by the odour produced by the Mogden sewage treatment works and after numerous complaints and a legal challenge with Thames Water in 2008, planning permission was granted to extend the site and improve the conditions to reduce odour while keeping residents informed.

Report a complaint or issue

If you're a resident experiencing problems with the smell, please report all Mogden odour issues to the council on 020 8583 2000, at the time they occur so it can be investigated immediately. 

If the odour is ongoing, we will visit the site to make an assessment. Updates are also available by calling the Mogden Information line on 020 8583 5745.

If you call the out of hours’ service, you will receive a response within one hour.
