| I don’t think it’s down to miss connected sewers at all. Lots of properties were built around 1899 / 1910 in the Grove Park and strand on the green areas. A lot of the properties had a dual sewage and surface water man hole in the front of there property. They were constructed with a gully running through at low level for sewage with a non return flap fitted on the entrance to the main sewer so any back up of the main sewer didn’t flow back into the house. There was another gully running though the same man hole at a higher level the carried the surface water out though a separate system and into the river. On one job I worked on many moons ago, the non return flap or valve on the sewer pipe got stuck closed, which allowed the sewerage to back up to the height of the surface water gully and mixed in with the surface water and then the mixture flowed into the river. I wonder how many houses have that problem in that area and other parts of older London |
