General Information
Location: The development includes Block 4, Lot 5 and Block 5, Lot 9 in the W.C.
Boyett Estate Partition Subdivision on College Main. The project is
located at 403 and 408 College Main, which are approximately 50 feet
northwest of Louise Ave on either side of College Main.
General Note: A 4" water line will connect to the existing 12" waterline and extend
across College Main to Lot 9 to provide water service for the building.
A 4" water service will also connect to the existing 12" waterline to
provide water service for the building on Lot S. The existing fire hydrant
at the corner of College Main and Louise Avenue will be used for
hydrant flow.
Land Use: Residential — Multi Family
Design Criteria/Analysis
Primary Water Supply: Existing 12" water line in College Main.
Domestic Demand:
Fixture Units: 403 College Main — 53.2
408 College Main — 45.6
Max. Demand Flow: 403 College Main — 30 gpm
408 College Main — 28 gpm
3/ " Water Meter for each structure
Fire Flow: 403 College Main is proposed to have a 8,730 sf building and 408
College Main is proposed to have a 7,395 sf building. Both buildings are
proposed to be Type V-B Construction per the hnternational Building
Code. In accordance with Table B105.1 of the International Fire Code,
the minimum required fire hydrant flows are 2,500 gpm and 2,250 gpm
respectively. Both buildings are proposed to have fire sprinkler systems,
therefore the minimum required fire flow is reduced to 1,500 gpm.
Existing System Pressure Tests:
Flow Hydrant: 315 College Main
Flowrate: 1,060 gpm
Static Hydrant: 405 Cross
Static Pressure: 70 psi
Residual Pressure: 64 psi

Exhibits: Exhibit A — Normal Flow Calculations
Exhibit B - Water System Flow Test Report
Exhibit C — Water Layout Exhibit
Water System Analysis: The residual pressure in the proposed water system is calculated to be 64
psi with a domestic demand of 58 gpm and 62 psi with a domestic and
fire sprinkler demand of 358 gpm. The residual pressure in the proposed
water system is calculated to be 58 psi at a fire hydrant flow of 1,500
gpm.
Conclusion
The proposed 4" water lines will provide water service to the building
and the existing fire hydrant and water system will meet or exceed all of
the design criteria for the City of College Station. It will provide
adequate water pressure and flowrate for both domestic and fire
protection demands.
