Hello everyone

i have interceptor sewer network setup in XPSWMM and i need to replace EXTRAN orifice/outfall weir regulator configration with automated regulator based on flow at the sysem STP.

XPSWMM manual and technical support recommed using inflatable weir which use the depth at any node to regulate the flow in any link. i made a test run using two inflatable weirs to simulate flow to interceptor and cso outfall. the results donot show any cso when the assigned depth in STP is exceeded.

Has anyone set up this type of model or have some insight on using automated regulators.

Thanks
