GENERAL INFORMATION
Location: The Castlerock Subdivision is located on the south side of SH 47 in southern
College Station near Arrington Road.
Area: Phase 1 A = 13.4 ac. 30 lots
Phase 2 = 13.5 ac. 27 lots
Phase 8 = 6.7 ac. 36 lots
Land Use: Single Family Residential
SEWER SYSTEM ANALYSIS (Phases IA, 2 and 8 only)
Design Criteria:
Primary Sewer Outfall: 21" sewer line along Spring Creek
Domestic Demand:
Avg. Pop Density: 2.67 people per lot
Average Flow: 100 gpd/cap or 267 gpd per lot
Peaking Factor: 4
Pipe: PVC D3034 SDR 26
Applicable Exhibits: Exhibit A — Sanitary Sewer Analysis Spreadsheet
Conclusion:
The sewer system for Phases 1A, 2 and 8 of the Castlegate Subdivision, consists of
a series of 6" and 8" lines that tie to the city's large trunk line along Spring Creek.
The analysis in Exhibit B checks the calculated slope required to pass the estimated
flow against the minimum slope required by TCEQ. The spreadsheet indicates the
minimum required slope is much greater than the computed slope, so we conclude
that the system is more than capable of carrying the anticipated flows from the
building.
