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 = 3.25 m³
