I'd always understood that drain capacity, like building techniques and indeed anything to do with building regs in general, could not be blockers for the purpose of planning permission. It may be demanded that the the developer widens roads, or installs new drains, as a condition, and that may be prohibitively expensive of course, but not a blocker. It may be that not all councils know this, or rules have very recently changed.
In a similar way you cannot use the fact that a radio antenna may be used to cause interference, or attract lightning,ectoplasm and ghosts or spread swine fever, in a planning proposal, only how it looks, and if it matches the building around it.
