The additional fire hydrant combined with the existing fire hydrant shall have sufficient capacity to meet
the IFC and the City of College Station requirements, and deliver water at the specified volume in the 8"
PVC Fire Line, below the maximum velocity of 12 ft/sec, and with water line pressures maintained above
76.26 psi under the stated delivery pressure and demand load.
