Steve, Good practice says you shouldn't feed more than one building from a riser but is there a reference from IBC that clearly states that? I agree that one pump can service several buildings on a campus (as long as it's in a separated pump house) just as a single pump can feed several risers in the same building or a municipal pump can service multiplke properties wuthin a water district.
