Example 3
| Determination of the required storage volume for a single-family house. | |
|---|---|
| The data for this example is taken from Example 1 and Example 2. | |
| * Roof area (brick): | 100 m² |
| * Yearly precipitation: | 750 mm |
| * Runoff coefficient incl. filter efficiency: | 78.4 % |
| => Rainwater yield: | 59 m³/year |
| Number of users: | 4 people |
| Connected fixtures: | Toilet, Washing machine, garden irrigation |
| =>Non-potable water requirement: | 60 m³/year |
| * The dimensioning of the storage volume follows the 5% rule: | |
| Storage volume: 0.05 x 59 m³ + 300 L = | 3.25m³ |
