24-Hr Demand Curve (residential)

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

RE: 24-Hr Demand Curve (residential)

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.

Steve -

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

RE: 24-Hr Demand Curve (residential)

Have a look at the following web site, the information you want is probaly in there somewhere - sorry I can't be more specific.

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
