There is a blocked foul sewer in the Pickle Ditch at Priory Retail Park in Merton which is causing raw sewage to leak into the river.  Thames Water have responded promptly and have deployed aerators where the Pickle Ditch meets the Wandle.  They also have tankers at St Georges Avenue overpumping the blocked sewer. Our thanks to Thames Water and the Environment Agency for their quick response.

Although there are  a number of reasons this sort of thing happens, one of the main causes is fat blockages. We can all help stop these things happening by never pouring oil or fat down the drains! Always dry wipe your plates, cooking tins etc.. before washing up.
