Rainwater utilisation

A wide range of applications for use of rainwater

If the rainwater is properly treated, it can be stored for long time; and can be used in a wide variety of areas.

Extinguishing water

Rainwater can be retained as extinguishing water and thus represent an important component of a fire protection and safety concept.

Extinguishing water is retained in a central storage tank. If necessary, the rainwater is then directed to one or more extinguishing water extraction points.

Building cooling

The use of rainwater is ideally suited for cooling buildings with air-conditioning systems.

In particular, due to the low mineral content, significant advantages can be achieved in adiabatic exhaust air cooling compared to the use of tap water.

Process water

There is a high demand for water in industry:

Whether for humidification or cleaning, as cooling water, drilling fluid or transport medium: rainwater is perfectly suited for a wide range of industrial applications.

Laundry

Washing with rainwater is completely hygienically safe. No special washing machines are required for this. Properly collected rainwater is clear, colourless and odourless.

It is also softer than tap water. This is easier on the washing machine, less detergent can be used and the use of softeners is completely unnecessary.

Toilet flushing

Since rainwater is free of calcium or magnesium, urine scale does not form in the toilet. The toilet stays clean longer and the flush seal remains intact in the long term.

By treating the rainwater with the WISY 4-step system, the flush water is crystal clear and leaves no residue on the ceramic.

Animal farming

Whether for watering livestock, for animal care or for cleaning stables and machinery - rainwater has many applications in animal farming.

In addition, rainwater does not leave deposits in watering troughs and supply pipes. The clogging of nozzles by limescale is ruled out and decalcification systems are not needed.

Cleaning

Rainwater is perfect for cleaning in the household, cars and machines or buildings. Since it does not contain calcium, less cleaning agent is needed.

It is particularly enjoyable when cleaning windows: rainwater dries without leaving any residue. Thus, all surfaces remain streak-free.

Irrigation

Rain is the best water supply for gardens, green spaces and sports facilities. If the water is stored plants can be watered during periods without rainfall.

Advantage: Sprinklers, garden sprayers and nozzles remain free of limescale deposits and irrigation equipment lasts longer.
