Large roofs enable high rainwater yields

Especially where large quantities of water are needed, the use of rainwater can help to reduce costs. While tap water is becoming increasingly expensive, rainwater is available free of charge. Large roofs offer the ideal prerequisite for cost-effective own water supply.

Save fees for precipitation water

Industrial buildings seal large areas of ground on which rainwater can no longer seep away naturally. In many countries this results in additional costs for the company in the form of the drainage fee if the rainwater is channelled into the public sewer systems. By using rainwater the company can be partially or even completely exempted from the fee.

Longer maintenance intervals of machines

In addition, rainwater harvesting in industrial applications sometimes offers advantages that are due to the properties of the water. Rainwater has a significantly lower mineral content than tap water in many places. This prevents limescale deposits, protects industrial machinery and can contribute to longer maintenance intervals. Investment and operating costs for a water softening system are reduced or eliminated entirely by using rainwater.

Implement ecological corporate goals sustainably and efficiently

In large companies, ecologically sustainable corporate goals are becoming increasingly important. In this context, the conservation of natural resources plays an important role, which gives rainwater harvesting an additional plus. It offers optimal conditions for reducing the consumption of public mains water, which is costly in terms of energy and purification technology.

Step 1: Filter

Before the rainwater enters the cistern, all particles with a diameter of more than 0.28 mm are filtered out.

Step 2: Smoothing Inlet

A particularly calmed inflow into the cistern ensures that no sediments or particles are stirred up. This means that clear water is always available for a wide range of applications.

Stage 3: Floating suction filter

When water is drawn from the cistern, a floating suction filter is used to protect the pumps and valves.The water is taken from the cleanest part of the cistern, which is about 20 cm below the surface. This provides the best possible water quality.

Stage 4: Overflow

Regular overflow of light and floating debris via a siphon with skim effect ensures that no separation layer can form between air and water. Thus the exchange of oxygen is at its optimum.
