Thames Tideway, the necessarily expensive ($6 billion?) new sewer running for a long distance underneath the River Thames in central London, has recently celebrated the completion of the tunnelling of the 25km storm overflow relief with a cello concert in the 50m deep tunnel.

Importantly, in the public debate about storm overflows now raging in England, Tideway helpfully explain that "The new sewer is designed to capture more than 95 per cent of the sewage [storm overflows] entering the river from London’s Victorian sewer system."
Even with a system of this sophistication and expense there is always going to be the need for storm overflows - but hopefully now in exceptionally exceptional times.
