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.
The construction of Section 200 will include the extension of the existing 12" sewer line in
Castlegate and the installation of some of the trunk lines that will carry wastewater flows from
many future phases. As a result, it is critical that these lines be designed to accommodate all
anticipated flows from the subdivision. The analysis that follows reviews all lines in the 202 acre
subdivision to determine their ability to function properly under fully developed conditions.
The tract of land that comprises this subdivision lies across a drainage divide that cannot be crossed
using gravity lines. As a result, a lift station is being planned in a later phase of the development.
The force main from this development will empty into one of the trunk lines that serves much of
the rest of the development. On the spreadsheet shown in Exhibit B, the force main is shown as a
12" gravity line for computational purposes.
Design Criteria:
Primary Sewer Outfall: 12" sewer line at existing terminus of Victoria Avenue
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 — Overall Sewer System Layout
Exhibit B — Sanitary Sewer Analysis Spreadsheet
Conclusion:
The sewer system shown in Exhibit A has been laid out using the criteria in the Bryan/College
Station Design Guidelines. It is analyzed assuming peak flow conditions when the subdivision is
fully developed. The spreadsheet in Exhibit B shows all lines depicted in Exhibit A to be capable
of carrying of the flows that come to them under these conditions. This analysis will be used as
the basis for all subsequent sewer line designs in the subdivision. The system will function as
intended as long as the line sizes and slopes are equal to or greater than those shown herein. It
should be noted that any significant additional flow from off -site sources will likely exceed the
capacity of several lines, so careful study is advised of any changes to the contributing area.
