Before you think this is a bad idea consider what could happen. We would dearly love to have a FDC at every riser. We have a fire pump feeding an UG loop serving over 3 million square feet of industrial property. The system has a master FDC to the loop at the city connections (never been used) but the fire pumps are fed from the reservoirs. When the fire main breaks, which it does an average of 2.5 times a year, we back feed risers through the 2-inch drain connection. Each time the fitters have to undo the piping to install hose connections. It would be very nice to have a ready-made connection at each riser. Sometimes we have to run a a couple of hundred feet of hose to get to a hydrant that has pressure, but at least we have some service to the riser. So, don't condemn the idea. They are just thinking a little farther down the road than most people.

The great City of Phoenix is set to amend the requirements of all the NFPA standards regarding FDC's. They will now require an industrial complex supplied by a fire pump taking suction from the city main, to have an FDC on the pump discharge and in addition, an FDC on every individual sprinkler riser or manifold fed from the underground supply from that pump, because there are sectional gate valves (in roadway boxes) in the underground yard mains that are not locked or monitored! So a 300,000 sf single building will now have up to 10 separate FDC's scattered around the facility. FYI, the only hydrants available for use in pumping into these FDCs are fed from the private fire pump. ?? Is anyone else around the solar system experiencing this level of micro-management? Comments, feedback? Frustrated in paradise.
