Highway drainage oufall

Did Infra-Road cover drainage outfalls? Typically highway drainage flows through an interceptor and then into a local watercourse through an ‘outfall’ (usually a pipe through a concrete headwall). Ive looked at other threads describing outfalls from a flat roof as being a void through the wall but in terms of a drainage system do you just have the last IfcPipeSegment and leave it at that? None of the IfcFlowTerminal objects seem to cover it. None of the enumerations for IfcWasteTerminal seem right. What would be considered ‘best practice’?
