I have seen only one such system and coincidently it was used at nursing home. Five or six high volume wells, each with their own pump supplied water to very large buried vertical pipe. A vertical turbine fire pump was installed to provide the hydrants and sprinklers. Smaller pumps were used for domestic water. The domestic pumps became the pressure maintenance pumps for the yard system. The fire pump was started by flow switch activation. We called this a canned pump because the vertical pump hung in an 8-10 ft. diameter tube full of water.

A single automatically controlled fire pump installed in accordance with NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, shall be an acceptable water supply source. A15.2.2 An automatically controlled vertical turbine pump taking suction from a reservoir, pond, river, or well complies with 15.2.2. I have an owner that wants to supply domestic water and fire protection water with a vertical turbine pump on a well. Does this pump need to be installed per NFPA 20? Does this pump need to be a listed fire pump? I've always ASSUMED that if a pump supplied fire protection it needed to be a listed fire pump installed per NFPA 20. Now I'm not so sure.
