Sewage Flow Estimation

Wastewater flow is derived from water consumption, reduced by a return factor.

Formulas

Average sewage = Water demand x Return factor

Peak sewage = Average x Peak factor x (1 + Infiltration)

The return factor (0.7-0.9) accounts for water consumed (irrigation, evaporation) that does not reach the sewer. The peak factor accounts for diurnal variation, and infiltration accounts for groundwater entering through pipe joints.

Exemple Résolu

2000 m^3/day water demand, 0.8 return factor, 2.5 peak factor, 10% infiltration.

  1. Average sewage = 2000 x 0.8 = 1600 m^3/day
  2. Peak sewage = 1600 x 2.5 x 1.10 = 4400 m^3/day
  3. Peak flow rate = 4400 / 86.4 = 50.9 L/s
