This is an actual network.

I ran the attached with zero Courant Factor as well as with 0.75. My hand calcs show inflow to be 118 m3 instead of 147 m3 produced by SWMM5 in either case. Inflow to a node is based on 0.011 LPS ADWF per tenement. My time pattern sums to 1.

I am trying to match the pump starts in a 24 hr period. Actual is 63. Programme yields 89. If I can get the inflow right, maybe there will be better correlation.

Can some one have a quick look at this please?
