In the UK (and like many places) there are 2 systems of water drainage
Not necessarily, older systems tend to be combined systems where sewage and rainwater go down the same pipes and are treated before going into the river. London (where this story takes place) is like this as the system was built in the 1800s when they didn’t care about treating water before it went into the Thames. This becomes a problem when it rains too much and it overwhelms the treatment system so they just dump untreated sewage into the Thames like the good old days.
Then again maybe they’re building a parallel separated system to try and reduce the load during heavy rains. Ie. We were rebuilding this road anyway, might as well connect it to a new storm water drainage system instead of sending it to the old Victorian one, and that’s why they don’t want people dumping.
Your main point is correct for most people living in places that were developed in the 1920s or later, don’t dump shit in the storm drains.
