WATER & SEWER ANALYSIS MB ii 111 FOR EDELWEISS GARTENS PHASE 7 COLLEGE STATION, TEXAS APRIL2006 :MBESI# 1059 .. 0002 SUBMITTED BY: McCLURE & BROWNE ENGINEERING/SURVEYING, INC. 1008 Woodcreek Drive, Suite 103 •College Station, Texas 77845 (979) 693-3838 • Fax : (979) 693-2554 •Email: McClureBrowne@Verizon.net WATER AND SEWER SYSTEM ANALYSIS FOR EDEL WEISS GARTENS, PHASE 7 General Information Area encompassed by this phase: Anticipated land use: Anticipated number of lots: Notes on surrounding development: 10.7 acres Single family residential 50 lots The area surrounding the site is developing with existing phases of Edelweiss Gartens to the south and west, and Bald Prairie Subdivision to the east and north. Water System Analysis Primary water supply line: Secondary water supply line: Software model: Average daily flow: Peaking factor: Estimated peak domestic demand: Estimated fire demand: Pipe material: Most Hydraulically Remote Point: Existing 12" line on Victoria Avenue Existing 8" line on Passendale Lane and an 8" line on Eagle A venue that is part of Edelweiss Gartens, Phase 6. Additionally, an 8" line has been built along Renee Lane. The Phase 7 water system will tie into this line. However, the model does not include the new 8" line, and demonstrates that the Phase 7 water system operates within the City's requirements without the connection. PIPE2000 (Kentucky Pipe Network Model) 267 gpd (0.185 gpm) per residential lot 4.0 0.75 gpm per residential lot 1000 gpm PVC (C909) Node EG7-02 (See Exhibit A) This is determined by calculating the lowest pressure under static conditions. Note that the lowest pressure in the model occurs in Phase 8 (EGB-10) Desi ned I Re uirement I Notes Conclusion: The proposed water system exceeds the requirements of TCEQ and the Cities of Bryan and College Station Edelweiss Gartens, Phase 7 MBESI # 10590002 Applicable Exhibits: Exhibit A Exhibit B Exhibit C Exhibit D Exhibit E Exhibit F Primary outfall line: Software model: Average daily flow: Peaking factor: Pipe Material: Manning's N value: Spreadsheet Notes: Conclusion: Applicable Exhibits: Exhibit G Exhibit H Exhibit I Schematic Water System Layout City of College Station Fire Flow Test Report 1 City of College Station Fire Flow Test Report 2 City of College Station Fire Flow Test Report 3 PIPE2000 Model Output for Edelweiss Gartens, Ph 7 (static) PIPE2000 Model Output for Edelweiss Gartens, Ph 7 (fire flow) Sewer System Analysis 8" Line on Eagle A venue Microsoft EXCEL Spreadsheed based on Manning's Equation 267 gpd per residential lot 4.0 PVC (D3034 and D2241) 0.013 The spreadsheet m Exhibit H analyzes the entire system for Edelweiss Gartens, Phases 5-12. It computes the anticipated flowrates from each area and the minimum slopes of the lines that serve those areas. It compares the computed slope with either the required minimum slope or the design slope from the plans. If the computed slope is less than the minimum or the design slope, the spreadsheet indicates the line is "OK". All of the lines in the spreadsheet on Exhibit H indicate they are OK and thus meet the design guidelines of the Cities of Bryan and College Station. Therefore, we conclude that the lines are adequately sized and will easily carry the sewage flows that are expected to pass through them.
