1.0 INTRODUCTION & DESCRIPTION
The purpose of this report is to provide a description of the proposed waterlines to be
constructed with the Castlegate Subdivision, Section 7, and to provide the results of the
analysis of the waterlines under fire flow conditions. An existing 12" waterline is located
along Castlegate Drive adjacent to the project site. The proposed waterline to supply the
site will connect to an existing 8" waterline stub previously constructed with the 12"
waterline. The water main will be constructed using 8" diameter pipe. The 8" waterline for
this project will be constructed of DR-14, PVC pipe meeting the requirements of AWWA
C-909 with mechanical joint fittings.
2.0 FIRE FLOW REQUIREMENTS
The flow required for fire hydrant flow for the subdivision is 1,500 gallons per minute
(gpm), which can be split between 2 adjacent fire hydrants.
3.0 WATERLINE SYSTEM ANALYSIS
The waterline system was analyzed using the WaterCAD computer program developed by
Haestad Methods, Inc. Exhibit "1" is a schematic of the proposed waterline, which shows
the locations of the fire hydrants. A normal domestic use flow of 1.5 gpm was included in
the analysis for each residential lot. This results in a normal demand of 36 gpm, which was
included in the analysis.
The residual pressure in the existing 12" waterline was determined by calculating the
headloss at a flow of 1,536 gpm for the existing line. Exhibit "5" presents the results of a
pressure/flow test from fire hydrants connected to the existing 12" waterline along
Castlegate Drive. A static pressure of 90 psi and a residual pressure of 85 psi with the
hydrant flow at 1,140 gpm were determined by College Station Public Utility personnel.
The residual pressure of 81.3 psi at a flow of 1,536 gpm was calculated using the following
equation:
QR = QF (HR/1100.54
Where: QR = Q available @ desired residual pressure
QF = Q during fire flow test
HR = pressure drop to desired residual pressure
HF = pressure drop during fire flow test
This results in a residual pressure of 81.3 psi where the proposed waterline will connect to
the 8" stub on the 12" waterline. The hydraulic grade was set at this pressure at the start of
the proposed waterline, Junction R-1.
The computer model was run with a fire flow of 750 gpm for each combination of 2 of the 3
fire hydrants proposed for this project. Exhibit "2" is a summary of the pipe system
junction nodes for this scenario. The lowest residual pressure occurred in the system at
Junction J-12. The pressure at this point is estimated by the model to be 66.9 psi, which
exceeds the minimum of 20 psi required by the TCEQ regulations.
Exhibits "3" & "4" are summaries of the pipe sections for the system Lmder this demand
scenario. The maximum velocity for the 8" water mains is 9.80 feet per second, and occurs
in Pipes P-1 and P-2.
A separate analysis was run for the domestic use of 1.5 gpm per unit, and the minimum
residual pressure was 72 psi, which exceeds the minimum pressure of 35 psi required by
TCEQ. Minor losses in this system were not calculated, as they were assumed to be
insignificant.
4.0 CONCLUSIONS
The waterlines proposed for this development should adequately provide the fire flow
required with acceptable values for headloss and velocity. This analysis was done assuming
adequate residual pressure in the existing 12" water main, as determined by the flow test.

1.0 INTRODUCTION & DESCRIPTION
The purpose of this report is to provide a description of the proposed waterlines to be
constructed with the Castlegate Subdivision, Section 7, and to provide the results of the
analysis of the waterlines under fire flow conditions. An existing 12" waterline is located
along Castlegate Drive adjacent to the project site. The proposed waterline to supply the
site will connect to an existing 8" waterline stub previously constructed with the 12"
waterline. The water main will be constructed using 8" diameter pipe. The 8" waterline for
this project will be constructed of DR-14, PVC pipe meeting the requirements of AWWA
C-909 with mechanical joint fittings.
2.0 FIRE FLOW REQUIREMENTS
The flow required for fire hydrant flow for the subdivision is 1,500 gallons per minute
(gpm), which can be split between 2 adjacent fire hydrants.
3.0 WATERLINE SYSTEM ANALYSIS
The waterline system was analyzed using the WaterCAD computer program developed by
Haestad Methods, Inc. Exhibit "1" is a schematic of the proposed waterline, which shows
the locations of the fire hydrants. A normal domestic use flow of 1.5 gpm was included in
the analysis for each residential lot. This results in a normal demand of 36 gpm, which was
included in the analysis.
The residual pressure in the existing 12" waterline was determined by calculating the
headloss at a flow of 1,536 gpm for the existing line. Exhibit "Y' presents the results of a
pressure/flow test from fire hydrants connected to the existing 12" waterline along
Castlegate Drive. A static pressure of 90 psi and a residual pressure of 85 psi with the
hydrant flow at 1,140 gpm were determined by College Station Public Utility personnel.
The residual pressure of 81.3 psi at a flow of 1,536 gpm was calculated using the following
equation:
QR = QF (HR/HF) 0.54
Where: QR = Q available @ desired residual pressure
QF = Q during fire flow test
HR = pressure drop to desired residual pressure
HF = pressure drop during fire flow test
This results in a residual pressure of 81.3 psi where the proposed waterline will connect to
the 8" stub on the 12" waterline. The hydraulic grade was set at this pressure at the start of
the proposed waterline, Junction R-1.
The computer model was run with a fire flow of 750 gpm for each combination of 2 of the 3
fire hydrants proposed for this project. Exhibit "2" is a summary of the pipe system
junction nodes for this scenario. The lowest residual pressure occurred in the system at
Junction J-12. The pressure at this point is estimated by the model to be 66.9 psi, which
exceeds the minimum of 20 psi required by the TCEQ regulations.
Exhibits -3- & -4" are summaries of the pipe sections for the system under this demand
scenario. The maximum velocity for the 8" water mains is 9.80 feet per second, and occurs
III Pipes 11-1 and P-2.
A separate analysis was run for the domestic use of 1.5 gpm per unit, and the minimum
residual pressure was 72 psi, which exceeds the minimum pressure of 35 psi required by
TCEQ. Minor losses in this system were not calculated, as they were assumed to be
insignificant.
4.0 CONCLUSIONS
The waterlines proposed for this development should adequately provide the fire flow
required with acceptable values for headloss and velocity. This analysis was done assuming
adequate residual pressure in the existing 12" water main, as determined by the flow test.
