What are storm overflows?

We don't usually like to think too much about what happens when we flush the loo but sewer overflows are an important part of the sewerage network which takes away the used water from our homes. We call them storm overflows and, while they probably don't crop up in your everyday conversation, they play a major part in preventing flooding in our streets and homes.
