Would add that there is a lot of misinformation.

Many leak problems are not to do with ancient pipes. Many are plastic pipes from early days of their use. Some of the joining techniques used in early days have proven not to age well. Severn Trent have a test area where different types of pipes over the decades are left in the ground with water going through them and monitored for performance over many years.

The issue with sewage we all care about will require a massive overhaul of the waste system to separate sewage and runoff water for an absolute solution. Most cities and towns will need all roads digging up.
This does introduce another problem regarding adequacy of flow to maintain function of sewage system.

There are simple measures to reduce storm surge. On Isle of Wight (?) homes were fitted with rainwater tanks to gutter down pipes that stored a lot of water and slowly released into drains. That was a pilot and haven't been able to find report above it.
