## 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.

计算示例
2000 m^3/day water demand, 0.8 return factor, 2.5 peak factor, 10% infiltration.
- Average sewage = 2000 x 0.8 = 1600 m^3/day
- Peak sewage = 1600 x 2.5 x 1.10 = 4400 m^3/day
- Peak flow rate = 4400 / 86.4 = 50.9 L/s
