Sewage Durchfluss Rechner — Formel

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.

Lösungsbeispiel

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
