romell I don't think water can escape the filters, as its all piped.
Not that im a waste water specialist, although we do have one on SW.
I think the biggest danger to filtration plants is ironically, rainfall - it can overload the system.
And of course, there are many and varied types and qualities of filtration plants.
I think the japanese have such an advanced system they recycle something like 97% of all their water.
Not that we are all as efficient as them🤷♀
