WATER AND SEWER SYSTEM ANALYSIS
FOR
CARTER'S CROSSING, PHASES 1 - 4
General Information
Area encompassed by this phase: 47 .7 acres
Anticipated land use:
Anticipated number of lots:
Single family residential
140 lots
Notes on surrounding development: The site is bordered to the north by Raintree
Subdivision, to the south by Emerald Forest
Subdivision, and the east and west by undeveloped
land.
Water System Analysis
Primary water supply line: Existing 8" line on North Forest Parkway
& Existing 8" line on Raintree Drive
PIPE2000 (Kentucky Pipe Network Model)
267 gpd (0.185 gpm) per residential lot
Software model:
Average daily flow:
Peaking factor: 4.0
Estimated peak domestic demand: 1.5 gpm per lot (per TCEQ requirements)
1000 gpm Estimated fire demand:
Pipe material: PVC (C909)
Most Hydraulically Remote Point: Node J-16 (See Exhibit A)
Conclusion:
Applicable Exhibits:
Exhibit A

Exhibit C
ExhibitD
Exhibit E
This is determined by calculating the lowest
pressure under static conditions.
20 (min Fire flow conditions
12 (max) Fire fl.ow conditions
The proposed water system exceeds the requirements of TCEQ
and the City of College Station

The spreadsheet in Exhibit G analyzes the entire system for
Carter's Crossing, Phases I - 4. 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 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.

Dear Mr. Herrin:
The purpose of this letter is to provide the TCEQ with the information necessary to comply with the
requirements of §317.1 (a)(3)(D) of the TCEQ' s rules titled, Design Criteria for Sewerage Systems.
The necessary information includes:
1. Engineering Firm: McClure & Browne Engineering/Surveying, Inc.
1008 Woodcreek Drive, Suite 103
College Station, Texas 77845
2. Design Engineer: Jeffery L. Robertson, P.E. No. 94745
3. Facility Owner: City of College Station, Brazos County, Texas
4. The plans and specifications which describe the project identified in this letter are in
substantial compliance with all requirements of Chapter 317.
5. Project Description: The wastewater improvements that are detailed within this project are
located within the City of College Station in Brazos County, Texas,
and are designed to connect to the existing wastewater collection
system. The project involves the extension of an existing sewer line
into a new subdivision located near the intersection of Appomattox
Drive and North Forest Parkway. The project consists of eight new
