We have completed a fire flow analysis for the Bluff Creek Cottages north west of County
Road 14, south west east of Bluff Creek Drive using WaterCAD by Bentley to model the pipe
network. We had information on the existing hydrant at the south west intersection of Bluff
Creek Drive and County Rd 14. From previous analysis we have the following information
1. Flow tests at the Hydrant at the south west intersection of Bluff Creek Drive
and County Rd 14. has static pressure of 85 Ibs, a residual pressure of 79lbs,
and a GPM at 1554.
The requirements were to model the most remote hydrant or the highest to ensure adequate
fire flow of 1,500 GPM while maintaining 20 PSI. The system was modeled off the data from
the hydrant referenced above. The results are as follows
Hydrant outside of the building (node J18) a fire flow rate of 2,453 GPM at a pressure of
24.7 psi, the hydrant at the intersection of the driveway and County rd 14 (node119) has a fire
flow rate of 3,000 GPM at 29.8 psi.
Enclosed is a copy of our calculation and watermain layout.
