08-5 Calculate and compare the hydraulic and TSS loadings (lb/d)
from wastewater and stormwater for a 10-acre urban neighborhood.
Assume the following:
*Wastewater: 5 houses/acre; 3.5 people/house; 50 gal/person/day; TSS = 200 mg/L
*Stormwater: 0.75 inch rainfall over 24 hours, 50% of rainfall runs off; TSS = 60 mg/L
Answer: WW load = 875 gpd, 14.6 lb/d; SW load = 101,820 gal/d, 51.0 lb/d
Since both WW and SW are substantial in amount therefore separate sewers are to be used for managing both.
