rainwater collection systems / rainwater harvesting systems
Rainwater collection systems or rainwater harvesting systems as they are also called are modular systems with several components to collect, store and use rainwater.
Whether you are interested in a rainwater collection system for private or commercial use, you will find a wide range of rainwater collection systems at WISY. Below, we summarize the functions and benefits of rainwater collection systems and rainwater harvesting systems.
Why rainwater collection systems are more than useful
In Germany, about 120 liters of drinking water are used per day per person. In other countries it is even more. Regionally declining groundwater supplies are often reflected in rising prices for the use of tap water.
As tap water is often of controlled quality and in many places worldwide also very scarce, so it is just too precious to waste for many simple applications in everyday life or in industry.
A costeffective and sustainable alternative is the use of rainwater with the help of a rainwater collection system. Often it is less polluted than groundwater and cheaper than water from the tap.
The design of a rainwater collection system
Rainwater collection systems can have a different designs depending on their application. But usually they have major components, which just vary in size depending on the area of application of the complete rainwater system.
All rainwater collection systems have a rainwater filter, which is used to remove coarse debris, leaves and other particles from the rainwater so that they do not enter the storage tank of the rainwater collection system.
In larger rainwater collection systems, the rainwater flows through a smoothing inlet into the lower part of a rainwater storage tank. Corrosion-resistant pumps with a floating suction filter take over the task of transporting the water to the tapping points in the larger rainwater system with mostly underground tanks. This design of a rainwater collection system can be found from single-family houses over industrial buildings to sports stadiums.
If, on the other hand, the rainwater is to be taken with a watering can, the rainwater system is largely reduced to a selfcleaning downpipe filter with a frost-proof rain barrel, as well as a tap for water extraction.
