Can someone define what's meant here by "raw sewage" please? Are we talking about wastewater from toilets?

- mike_hearn 3y agoLondon has one of the earliest sewer systems, and it predates the practice of separating storm drains from effluent drains. Normally the sewers drain through pipes to the water treatment works, but if there's too much rain then the system becomes full and it drains into the Thames to avoid flooding streets and buildings. The new pipe will fix that.

- rsynnott 3y agoRealistically, if your sewerage system is from before the mid-20th century, you'll usually have this problem.
- masfuerte 3y agoApparently, the first official inquiry into London's sewerage recommended a separated system, but Bazalgette prevailed and his design was a combined system. Other British cities, and other cities round the world, copied this design. https://news.sky.com/story/down-the-drain-what-went-wrong-with-britains-water-system-12987514 https://news.sky.com/story/down-the-drain-what-went-wrong-wi...
