Pipe Length - 6" (ft) WATER AND SEWER SYSTEM ANALYSIS PEBBLE CREEK, PHASES 9I General Information Pebble Creek, Phases 9I Page 1 of 2 14.32 acres Single family residential 27 lots The area surrounding the site is mostly developed with existing phases of Pebble Creek to the north, west and east, undeveloped phases of Pebble Creek lies to the south. Water System Analysis Existing 12" line on Pebble Creek Pkwy Existing 8" line on St. Andrew's Drive & 8" line on Congressional Drive 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 J -2 (This point was determined by calculating the lowest pressure under static conditions. - See Exhibits A & D) Table of Results As Designed 1 Requirement Notes 97.56 20 1 Fire flow conditions (J -9) 11.22 12 ' Fire flow conditions (P -40) 293..........._......; 5 00.... 835 1 1500 Conclusion: The proposed water system exceeds the requirements of TCEQ and the City of College Station Applicable Exhibits: Exhibit A Schematic Water System Layout Exhibit B City of College Station Fire Flow Test Report 1 Exhibit C City of College Station Fire Flow Test Report 2 Exhibit D PIPE2000 Model Output for Pebble Creek 9I (static) Exhibit E PIPE2000 Model Output for Pebble Creek 9I (fire flow) MBESI #10650013 Sewer System Analysis General Note: This sewer system drains to the existing 8" line that runs between Phases 9H and 9I. The lots in the proposed phase accounts for only a small portion of the capacity for the entire system. Primary outfall line: Existing 16" near the southern property line of Phase 9H Software model: Microsoft EXCEL Spreadsheet based on Manning's Equation Average daily flow: 267 gpd per residential lot Peaking factor: 4.0 Pipe Material: PVC (D3034) Manning's N value: 0.013 Spreadsheet Notes: The spreadsheet in Exhibit G computes the minimum slope of the lines needed to carry water at 2.5 feet per second or faster. If that slope is less than the minimum slope required by the Cities of Bryan and College Station, the calculated slope value appears in red and indicates that the line has adequate capacity even when laid on the minimum slope Conclusion: All of the lines in the spreadsheet on Exhibit G have computed slopes shown in red that are less than the minimum required by the City of 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.
