If you want to integrate a stream into your garden, you should let it flow down a slight slope - and also invest in a sensible pump. To ensure that the stream does not mutate into a trickle or even a torrent, the pumping power and thus the amount of water required should be adjusted to the circumstances.
What amount of water does a garden stream need?
To determine the appropriate amount of water for a stream in the garden, the following rule of thumb can be used: Width of the stream in cm x 1.5 gives the pump volume in liters per minute. The garden pond should be able to hold at least a third of the hourly amount of water.
Rule of thumb for the right pump
There is a simple rule of thumb for calculating the amount of water required and thus the pumping capacity for a stream:
Width of the stream x 1.5 gives the pumping volume per minute
A 40 centimeter wide stream therefore requires a pump that delivers 60 liters of water per minute. The water collection basin or garden pond, in turn, should be able to hold around a third of this amount of water - calculated per hour. At around 3600 liters per hour, the pond should therefore have a capacity of at least 1200 liters.
Tip
If your stream is unevenly wide, use the average value for the calculation.
