Example 1
| Calculation of rainwater yield |
|---|
| * Single-family house with 100 m² roof area and clay-brick roof |
| * Annual precipitation = 750 mm/year |
| * Runoff coefficient = 0.8 |
| * Filter efficiency = 0.98 |
| =>Rainwater yield = 100 m² x 750 mm/year x 0.8 x 0.98 x 10-3 = 59 m³/year |
