Not coming out of, but sharing the water supply with the building. Simplistically, if your building standpipe system is manual, then you can place your FDC on the service lateral and then split to separate building and dock systems. Again, maybe the local AHJ will buy it coming off the building system, but if it’s pumped for whatever reason, I’m a hard no on the 1,000 gpm water supply. Boat fires are different and so are response strategies, including joint response with a fire boat. If they think they may need 1,000, my first pass would be manual/manual and design the water supply so they can pump it.

However, my first reaction was why not. Pumps and underground are shared between buildings, why not between a building and a marina? Connected to a 1000 gpm pump, it would most likely end up automatic wet instead of manual dry. This opinion is based only on information previously received. There may be other circumstances that could make the preferred outcome different.

New construction of an 8 story hotel at the marina. Plans also call for a manual dry dock hose system. This will require, one, maybe two hose valves. The dock is located on the side of the hotel opposite the street. Civil plans call for an underground run from the front of the hotel, all the way around the property, along the sea wall, to the dock. I have a stair well, with a stand pipe in it, about 20 ft from where the dock hose valves would need to be. Can I delete the manual dry hose and feed from the hotel stand pipe system? Or even directly from the fire pump would be preferable to all the underground work. Can I change the FDC sign on the front of the hotel to include the dock hose valves? “Hotel & Dock FDC” My pump is already 1000GPM. Would adding these hose valves effectively make them part of the stand pipe system? Is there any reason in NFPA 13 or 14 that I can’t extend my stand pipe system out horizontally?
