So this tunnel is so huge not because it needs to be huge for the flow needed, but because the tunnel doubles up as a storage reservoir?
Is that really the cheapest way to make a storage reservoir? Wouldn't it have been cheaper to have a regular size pipe, and some big tank at the end?
- londons_explore 3y agoPart of me suspects it is done this way for political reasons. Nobody wants a sewage reservoir near their house. Everyone is scared of a reservoir potentially bursting and flooding a whole district with sewage. Whereas if you say "it's a big pipe to take sewage away", nobody can object to that. Everyone wants their sewage taken away. The fact the pipe is also acting as a reservoir becomes a technical detail.

- DrBazza 3y agoIt’s been over 50 years and we still haven’t built the only proposed reservoir in Kent at Broad Oak near Canterbury. We are useless at getting things done in the uk. That a third Blackwell Tunnel is being built is incredible.
- londons_explore 3y agoIt's raw sewage, so probably not on the surface. You'd dig up a few acres of park and put it underneath.
