So what you're saying is that all 14 homes don't have a sprinkler system. For if someone did then you'd know it's possible. I doubt a booster pump would rob them of the water they need. Maybe get the neighbors to chip in and boost the pressure to all 14 homes.
Seems to me you have enough flow to make something work. I'd rather have low pressure with good flow than high pressure and minimal flow.
I worked on a system on Monday. 80 pds pressure but couldn't run 6
1800 series Rainbird pop ups with 15H nozzles. Good luck!
If I can't fix it, it's broken!
