General Information
Location: The Breezy Heights Addition Block 4, Lots 5R, 6R, 7R & 8R.
General Note: These 4 proposed lots and the existing 15 residential lots will flow into
the existing 6" public sewer line and then into a manhole located on
Thompson Street. The existing line was analyzed for the entire block.
Land Use: Single Family Residential
Design Criteria
Primary Sewer Outfall: An existing manhole on Thompson Street.
Domestic Demand:
Avg. Pop Density: 2.67 persons per unit
Average Flow: 100 gpd /cap Residential
Peaking Factor: 4
Pipe: PVC ASTM D 3034 SDR 26 and Ductile Iron
Applicable Exhibits: Exhibit A — Sanitary Sewer Analysis Spreadsheet
Conclusion
The " ro osed 6" line is an extension of an existing 6" sewer line. The
P P .f g
analysis in Exhibit A checks the calculated slope required to pass the
estimated flow against the design slope shown on the plans. The
spreadsheet indicates the design slope is greater than the minimum
computed slope, so we conclude that the system is more than capable of
carrying the anticipated flows from this subdivision.
ExhibitAB also shows the full flow velocity in the proposed line at 2.63
fps and the calculated peak flow velocity at 1.29 fps.
