1,500 liters The choice of volume from recuperator ofrainwater also depends on how you want to use it throughout the year. If you water little (less than 50m²), a volume of 1 liter per year is necessary. For significant watering (more than 50 m²), your annual needs are between 5 litres.

How to calculate the amount of rainwater?

As we have just seen, 1 l is equal to 0.001 m³. We can also define that 1 m³ is equal to 1000 litres. So if we base ourselves on the formula for calculating a volume which is: length x width x height and we convert the result, we obtain a volume in liters. How to calculate the amount of rainwater?
