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 |
