Land Use: Single family residential
Design Criteria/Analysis
Fire Flow:
Dometic Use
Castle Rock Subdivision, Phase 5 Lots 26 -34, Block 1, Lots 16 -133,
Block 3 and Lots 17 -18, Block 4 is located adjacent to the existing
Phases 2A and 4 and future phases 6 and 7.
The water line to serve these 29 residential Tots will be a 8" line along
Rocky Vista Drive and Rock Bend Drive that will connect to the existing
6" water line on Hollow Stone Drive. The 8" waterline will continue
along Rock Bend Drive to serve Phase 7. A 6" line and 2 4" lines are
stub out along Rocky Vista Drive to serve Phase 6. The waterline layout
is shown on Exhibit A.
1,000 gpm for Single Family Residential
1.5 gpm per lot for Single Family Residential
The proposed 8' and 6" water lines are in accordance with the Revised
Water System Report for the Castle Rock Subdivision prepared in July
2007. This report provides the results of the water system analysis under
the fire flow and domestic demand requirements which produced the
lowest pressure in the system. The scenario with the lowest pressure was
with the fire flow of 2,500 gpm in the commercial area of the
Subdivision. This scenario resulted in a residual pressure of 73 psi
which is significantly higher than the 35 psi minimum residual pressure
required. All scenarios using 1,000 gpm for the fire flow for the
hydrants in the residential sections resulted in higher residual pressures.
Additional analysis of Phase 5 of the Subdivision was performed for this
report to verify that the previous analysis results could be confirmed.
Attached is a field fire hydrant flow test, marked Exhibit B, performed
by the City of College Station on July 2, 2008. The fire hydrant was
located in Phase 2A of the subdivision and the results of the test yielded
a flow of 1,300 gpm at a residual pressure of 94 psi.
A KYPIPE computer model was developed for the proposed waterlines
for the Castle Rock Subdivision, Phase 5. The model was run using a
fire flow of 1,000 gpm for each of the proposed Fire Hydrants on Rocky
Vista Drive. A maximum daily demand of 174 gpm was also used in the
analysis for the domestic demand from Phase 5 and 6 of the Subdivision..
The starting residual pressure was based on the fire hydrant flow test.
The node and pipe locations are shown on Exhibit A.
Conclusion
Exhibit C -2 is the KYPIPE output file with the domestic peak flow and
the fire flow from each of the hydrants. All node pressures exceed 89 psi
for this scenario which is greater than the 20 psi minimum required. All
the pipe velocities are less than 12 fps for this scenario. The maximum
velocity in any of the pipes is 7.5fps.
Exhibit C -1 is the KYPIPE output file with only the domestic peak flow
modeled. All node pressures exceed 99 psi for this scenario which is
greater than the 35 psi minimum required.
The proposed 8 ", 6" and 4" water lines meet or exceed all of the design
criteria for the City of College Station. It will provide adequate water
pressure, flowrate and velocity for both domestic and fire flow demands.
