Waste wonder


Some of us will have read of the Thames Tideway Sewerage Tunnel scheme with utter astonishment. While the overow of diluted sewage is immediately unattractive, Chris Binnie's brief dismissal of Professor Richard Ashley's observations is quite insufcient to satisfy those among us who may view this monster scheme with a natural scepticism.

River water quality through London has been improved enormously over recent decades, so what is the real damage from these overows?

Could it be that improved local physical treatment may be accommodated at comparatively modest expense to provide adequate results and avoid the enormous commitment of capital and operational expenses involved in the tunnel scheme?
