Ofwat: Strategic Priorities

I welcome the right hon. Gentleman’s mention of the Tideway tunnel. It is an enormously expensive project and collects a lot of the sewage from London, but not from any sewage treatment works above Hammersmith—by which I mean specifically Mogden sewage treatment works. Every time it rains more than a drizzle, Mogden and Thames Water discharge dilute sewage into the River Thames, and the Thames Tideway tunnel can do nothing about that.
