Pumps and Stored Water Supplies
Pumps and Stored Water Supplies
(OP)
Currently have a client who requires a stored water supply. Typically would recommend vertical turbine fire pump and cistern. However, the architect would like to have the stored water supply installed adjacent to the basement (burried underground), and have the fire pump installed in the basement.
I have seen this type of installation in some older buildings, using a horizontal split case pump. Is anyone familiar with this type of set up.....would you be concerned with zero suction or priming of the pump?
Any information would be apreciated.

RE: Pumps and Stored Water Supplies
Your other option is to have the "standard" underground tank stored close to the basement wall and then have a line from the tank go directly to the suction line of the fire pump.
Either option will meet all of the requirements of NFPA 20.
Please email or post if you need any further clarification.

Some insurers eg FM Global also have particular requirements concerning what is acceptable or not and you should check out the specific data sheets as well as NFPA 20.
