I am doing a small waterline extension to serve a development in a rural town. The town code requires fire flows of 1000 gpm. The two nearest hydrants were tested and gave 650 gpm and 750 gpm. Do towns usually let you bend the rules since their system does not provide required flow? If not, what options do we have? Upgrade their system? Pumps? Also, fire chief gave me hydrant data of 52psi static, 34 psi residual, and 650gpm at 15psi. What is the 34psi residual? I thought you need to have a residual pressure at a flow. I usually model system as a pump curve (52psi,0gpm 34psi,Xgpm 15psi,650gpm). How do I use this data? Is this typically all the information you get? Thanks.
