Public Hydrant Flow Procedure Clause Samples

Public Hydrant Flow Procedure. The minimum acceptable flow from any existing public hydrant shall be 1,000 GPM unless the required fire flow is less. Hydrants used to satisfy fire flow requirements will be determined by the following items: 1. Only hydrants that meet spacing requirements are acceptable for meeting fire flow requirements. 2. In order to meet the required fire flow: a. Flow closest hydrant and calculate to determine flow at 20 pounds per square inch residual pressure. If the calculated flow does not meet the fire flow requirement, the next closest hydrant shall be flowed simultaneously with the first hydrant, providing it meets the spacing requirement, etc. b. If more than one hydrant is to be flowed in order to meet the required fire flow, the number of hydrants shall be flowed as follows: One hydrant 1,250 GPM and below Two hydrants 1,251– 3,500 GPM flowing simultaneously Three hydrants 3,501– 5,000 GPM flowing simultaneously
