HomeMy WebLinkAboutWater System Report Water System Report for Castlegate II Subdivision, Section 200 College Station, Texas February 2011 (revised April 2011) Prepared By: Phillips Engineering 4490 Castlegate Drive College Station, Texas 77845 (979) 690 -3141 TPBE FIRM #13130 ••�....• ' *i M: "tom *: 43' AL Pr i' 8� Castlegate II Subdivision, Section 200 Water System Report General Information The Castlegate II Subdivision is a 202 -acre residential subdivision being developed immediately southwest of the existing Castlegate Subdivision in College Station. The recently approved Preliminary Plat shows a total of 629 lots in the whole development. The first phase will be Section 200, which is located adjacent to Castlegate Section 7 at the terminus of Victoria Avenue and will contain 47 lots. Since this is the first phase of a large development, an analysis was conducted on the entire water system to ensure its ability to serve all lots under fully developed conditions. This analysis was conducted with waterline sizes of 8" or less to demonstrate that larger size lines are not necessary even though they may be required by the City for future development in the area. A second analysis was conducted for Section 200 only to demonstrate that it can function as a stand -alone system. Revision Note: At the request of the City staff two additional analyzes were conducted using the 12" lines that are shown on the construction plans and included in the oversize request for Section 200. Computer models were changed to incorporate 12" lines as shown on the Preliminary Plat in both the fully developed conditions and in Section 200 by itself. Exhibits showing the results of those models have been added to this report. Design Criteria Primary Water Supply: Existing 8" line on Victoria Avenue and an 8" line that lies in an easement in Section 7 of Castlegate. Both lines will be used with the construction of Section 200 to provide looping in all future phases of the development. Domestic Demand: Avg. Pop Density: 2.67 people per lot Average Flow: 100 gpd /cap or 267 gpd per lot = 0.18 gpm per lot Peaking Factor: 4 Peak Flow: 0.74 gpm per lot Design Flow: 1.50 gpm per lot Fire Demand: Fire Flow: 1000 gpm at most hydraulically remote point Pipe: PVC DR -14 C900 Roughness Coeff 150 (Hazen Williams) Hydraulic Software: EPANet v.2.0 Existing City System Pressure Tests Flow Hydrant #: V -037 (Camber @ Victoria) Flowrate: 1430 gpm Static Hydrant #: V - 047 Static Pressure: 85 psi (196 ft water) Residual Pressure: 77 psi (178 ft water) Applicable Exhibits: Exhibit A — College Station Utilities Flow Test Report 1 Water System Summary of Entire System under Fully Developed Conditions In order to establish the most hydraulically remote point of the entire system, a model was run under peak flow conditions without fire flow added to the demand. The point with the lowest pressure is J107 -3, located in the lower left corner of Exhibit B. A fire demand of 1000 gpm was added at the nearest fire hydrant location, which is J107 -2. Results of that model are shown below. As Criteria Required Designed 1 Location Min. Pressure - fire (psi) 20 1 52.37 J107 -3 Max.
