GENERAL INFORMATION
Equinox Subdivision is a 21.842-acre development in the area generally bounded by Rock Prairie
Road to the south, Buena Vida and the Barracks II Subdivisions to the east and north. It is zoned GS
and TH and is comprised of residential land uses as shown on Exhibit A. There are 140 residential lots
planned for the site. The area surrounding the site is residential with an undeveloped tract to the
southwest.
Phase 2 of this subdivision will have a different sewer outfall.
Sewer service to the area is provided by a 6"line running along Kate Lane. This line will be the
outfall for phase 1 of this development. This report includes an analysis of the existing 6"sewer line
through the Buena Vida and Williamsgate Subdivision to where it connects to the 12"line. This
development is at the top of a hill and will not be serving any adjoining tracts as the tracts across Rock
Prairie Road already have sewer service and the Mayo tract will get service from the Barracks II
Development.
Design Criteria:
Primary Sewer Outfall: Phase 1 -6"sewer line at existing terminus of Kate Lane
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 and TCEQ. It is analyzed assuming peak flow conditions when this portion of the
subdivision is fully developed. The spreadsheet in Exhibit B shows all lines depicted in Exhibit A to
be capable of carrying 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.
