Opponents of home fire sprinkler systems often cite extremely high costs associated with integrating NFPA 13D home fire sprinklers into a well water supply system. The following will explain how this is accomplished in an efficient and cost-effective manner.
Well systems incorporating fire sprinklers at the start of the building process are set up to address this fire protection application. Water sits in three areas in a well-fed system: in the well above the pump, refilling into the well as it is used, and in the holding tank in the home. Per NFPA 13D the refill rate can be counted on to help supply part of the demand, thus, the duration demand of 7 or 10 minutes can be met by the sum of these three sources.
