That would be when enough water cannot be provided by the Schuylkill River. Note contamination levels. Highest contamination is from the Delaware River. Cleanest is from the Schuylkill. Delaware is used mostly when additional water is needed.

Water is fungible. That map is simply a ball park estimate when all plants are fully operational. Water from the Delaware needs more treatment - costs more. Whenever possible, Philadelphia uses cleaner (and therefore less expensive) water from other two plants.

Observe water approaching Philly's cleanest plant. Expect to see a dead body in it. That is Philly's cleanest water?

So again, what happens between Port Jervis and Philadelphia?
