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 lots are
located at 403 and 408 College Main, which is approximately 50 feet
northwest of Louise Ave on either side of College Main.
General Note: Existing 6" sewer lines run along the back side of each of the lots. A 6"
sewer service will connect to the existing lines and extend to each of the
buildings at 1.1%.
Land Use: Residential — Multi -Family
Design Criteria
Primary Sewer Outfall: The primary outfall for the services are the 6" lines along the back sides
of the lots.
Domestic Demand.,
Peak Flow: The peak flow from each building in this development was determined
from the fixture unit counts for each building. These counts are
summarized for each proposed building in the spreadsheet provided in
Exhibit B. The fixture unit counts were compared to Table 710.1(1) of
the Plumbing Code to verify the proposed pipe slope was greater than the
minimum slope required by the code. The maximum number of fixture
units for a 6" pipe is 700 units and the fixture unit count is 53.2 for 403
College Main and 45.6 for 408 College Main.
Pipe: PVC ASTM D 3034 SDR 26
Applicable Exhibits: Exhibit A — Sanitary Sewer System Layout
Exhibit B — Fixture Unit Count Determination
Conclusion
We conclude that the proposed sewer service lines are more than
capable of carrying the anticipated flows from each building in the
development.
