Peak flow graph

[swazimatt]

Does anyone have a graph showing standard or accepted peak factor flows throughout the day. I imagine there is a standard model that is used by modelling teams
I actually want it for wastewater modelling, but imagine they would be fairly similar

Seems like a stretch to look for a standard with global applicability.
I would think that all system operators have that for their own system, but global ... seems like a big stretch. 1.5 to 2? I lean toward 2.

Here's something for your arsenal

Try typing in "water usage data hourly" and look at the images. Quite a wide variation.

Domestic?
Industrial?
Leisure?
Village?
Town?
City?

Hot climate
Cold climate
Location
Affluence

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

There definitely is a dumbed down limit somewhere there.
