I need this to model peak and low flows for a rural water distribution system. Does anyone know where I can find something?

You need a diurnal demand curve, there will be two major peaks and troughs.

Metcalf & Eddy "WW Eng", on page 36 of mine, but it is '72 ed.

Clark Viesman & Hammer "Water Supply and Poll Control". on page 116 of mine, but it is '71 ed.

Thanks, diurnal helped me - I don't have that in my "The Civil Engineeing Handbook" Second Edition W.F. Chen, J.Y. Richard Liew. I want to describe a pattern with demand multipliers...peak day being 2.2 - 2.9 (but the total 24 hrs averaging to 1.0 or the base flow) using EPAnet2.0

Copy the following (between the quotes) into notepad and save it as "res.pat"
It is demand patern from a residential city of 10k using the telemetry system averaged over the year. The first entry (hour midnight) I use as a baseline then the model follows the telemetry

you can then load it into EPAnet in the patterns tab
