I hate to see a house surrounded by concrete walks.
This is an educational bldg, a school for teachers. The area you see is for the A/C units and is surrounded by a brick wall, thus none of this is visible. I know the lines are somewhat vulnerable to being kicked & etc but no more so than the A/C lines.
Could you have run it along the wall, around AC units and out the wall?
With downstream zone valves, the thing is a code fail. Backflow protection in a frostproof hydrant isn't for 24/7 water pressure.
You probably can't see it but the bib has a backflow built-in.
Not really practical, still would have to cross open areas.
Try running the approval numbers on the hydrant. They do not match any of those found on actual backflow prevention assemblies.
We have "backflow" components on all spigots for new homes here. They DO NOT meet backflow regulations, and if I recall, work basically like an AVB, not a PVB. So they are not meant to be under constant pressure.
For a school building with many kids, and no real backflow preventer, you are setting yourself up for a big lawsuit.
Where do I start? The tripping hazard or what looks like electrical conduit being used for water conveyance.
Since it looks like the brick just sits atop the concrete, it would be possible to drill a hole though the concrete, and tunnel a path to connect the system to the water.
