You could try suppling a bulk main to the remote area, essentially creating a loop system. I had a job where it was OH1 and got installed and then ended up getting reclassified as an OH2. We didn’t have enough water to feed the OH2 hazard so we ran a bulk main from the feed main to remote area. This worked for us.
