Yeah, nah, it is rather far from boil water notices tbh. Rather heavier rainfalls into mountainous bushclad terrain can significantly increase turbidity and faecal coeliforms in a reservoir.

So treating each cumec takes longer - filters clog faster, UV needs to be applied for longer...

Hence the water restrictions - throughput has to decrease to maintain quality.

Boil water notices occur when your water treatment has entirely failed.

I don't know how it is where you live, but here, boil water notices generally happen because of mundane things well downstream of water treatment. Water demand too high, dropping pressure? Boil water notice. Water main breaks? Boil water notice. In this case, although I wouldn't describe it as mundane, the boil water notice occurred because of a temporary power loss resulting in a pressure drop, not because the water was actually known to be contaminated.

It's also hard to compare across water treatment standards. Are the allowed contaminants the same? For example here, no amount of PFAS contamination results in an advisory, even though it's well over the limits.

I think a better point would be a) there's no such thing as the "American" water system; water systems are virtually all designed, implemented, run, and administered by municipal and county governments, with anyone remotely rural on a well; and b) any minor water failures in the US are going to garner extra attention for the next couple years because of the Jackson debacle.

OTOH, I have well water for myself. ;)

EDIT: Also here's a boil water notice in New South Wales from flooding events, 22 days ago.

Not starting.

"The NSW Government has announced that Water Wise Guidelines have replaced Level 1 water restrictions [...] The restrictions have eased, but let’s stay water wise."
