Mr. Stephen Cast
Wellborn Special Utility District
P.O. Box 250
Wellborn, Texas 77881
RE: Graham Rd. and South Dowling Rd. Proposed Subdivision Service Study
Dear Stephen:
The current KYPipe model for the Wellborn SUD Main System was used to perform a water
service analysis for a proposed residential development located at the corner of Graham Rd.
and South Dowling Rd. in the extraterritorial jurisdiction of College Station, Texas. According
to a July 23, 2014 letter from the developer's engineer, the proposed residential
development would serve 21 new connections within a 31.5 acre subdivision.
Our analysis indicates that service is available for the proposed development to meet TCEQ
requirements for residential use of 1.5 gpm per connection and a minimum residual pressure
of 35 psi. Our analysis also indicates that service is available to provide the minimum fire
flow requirements for the City of College Station. The City's fire flow requirements are to
provide 1,000 gpm from two adjacent fire hydrants at a minimum operating pressure of 20
psi while supplying the maximum demand of 0.76 gpm per connection. Any dead end water
lines within the proposed development providing supply to a fire hydrant need to be a
minimum of 8" in diameter. Tie-in to the Wellborn SUD water system can be made at the
existing 6" line along Graham Rd. If a fire hydrant is required to provide service to the
proposed lots numbered 15 and 16, it can be placed on the existing Wellborn SUD 6" line
along South Dowling Rd. or Graham Rd.
We appreciate the opportunity to provide this information. Please do not hesitate to call if
you have any questions or comments.
Sincerely yours,
Winn Professional Engineers & Constructors, LLC
