Stormwater Management

Stormwater Management for Family Houses

Can rainwater be dirty, discoloured or even smell? Yes, it can. Although rain is practically distilled water at the moment of its creation, it comes into contact with various chemicals as it passes through the atmosphere. These come from both natural sources and human activity - for example, sulphur and nitrogen compounds produced by the burning of fossil fuels. Added to this are substances released from the surrounding environment.

However, the largest source of stormwater pollution is the roof surface itself, where dust, pollen, soot and other contaminants accumulate during the dry season. In this sense, every drop of rain can be said to act as a filter for the atmosphere - and the resulting composition is accordingly. The quality of rainwater therefore depends primarily on the nature of the surrounding environment. In urban and industrial areas, the level of pollution is generally higher.

Nevertheless, rainwater can be used very well after treatment as utility water - for example, for irrigating gardens, flushing toilets, washing clothes or for various technological purposes. The possibilities of use are much wider.

Rainwater is a quality and available resource that should be managed responsibly. Today, it is often charged for its discharge into sewers and it is expected that charges will be introduced across the board in the future. In addition, not every plot of land has suitable conditions for septic tanking. Proper stormwater management is also essential for the development of blue-green infrastructure - it helps maintain urban green spaces and mitigate the heat island effect. The ability to retain and use rainwater efficiently thus becomes key to maintaining a favourable climate.

Yet the potential of rainwater is often untapped in practice. In many cases, it is replaced by other sources such as grey water recycling or pumping from wells. Yet buildings such as schools, kindergartens, sports facilities, industrial and logistics sites can benefit significantly from rainwater harvesting - both environmentally and economically.

If you want to have control over the quality of your water and ensure trouble-free operation, hygienic cleanliness and safe use, we recommend that you consider a water treatment plant. For this purpose, we have designed the AS-RAINMAN block water treatment plant, which is easy to install and ready for immediate use - without the need for complex assembly of individual components.

Advantages of installing an AS-RAINMAN water treatment plant:

• microbiologically safe, clean water
• improved taste, colour and smell of the water
• removal of turbidity
• Reduction of heavy metals, organic and pesticidal substances, chlorinated hydrocarbons, volatile substances and humic substances
• Significant savings in drinking water and reduction in sewerage costs

Size variants
AS-RAINMAN block treatment plants are available in a variety of sizes - from models for single-family homes and cottages to solutions for large-scale facilities such as office complexes or industrial plants. We offer standard solutions for daily rainwater consumption up to 20 m³, while individual configurations can be designed if required.
