Climate change affects rainfall events. This is increasingly evident in heavy rainfall events. Overloaded sewer systems and an imbalanced urban climate are the consequences. To be well-prepared for these consequences, intelligent and sustainable solutions are needed.
With ARIS’s intelligent systems, it is possible to combine rainwater retention, utilization, or infiltration. Through automatic comparison with weather forecasts, optimal utilization of the retention, usage, and/or infiltration volume is ensured. This leads to smaller and more cost-effective designs.
Better does not mean more expensive. Despite the use of high-quality, smart components, the investment is worthwhile – not least financially. Although the acquisition costs are slightly higher, a smart system can quickly amortize itself and even offers the possibility of generating profit. And that after approximately half of the average system lifespan.
The example of a model school illustrates how required rainwater retention can be expanded to rainwater utilization without having to build a larger tank.
With 600 students and teachers and an available collection area of approx. 2,800 m², the daily operational water demand of 12 m³ can be met with an 85 m³ tank.
These values are the starting point for ARIS’s proprietary computer simulation process, which precedes system construction.

The additional investment costs of an intelligent system, compared to a pure retention system, amortize themselves after just over 5 years. After 11 years, such a system even begins to generate profit. After 20 years, an intelligent system can have generated over €61,000 in profit, whereas a conventional system would have incurred an annual loss of approx. €1,900.
By linking multiple systems and their intercommunication, ARIS makes it possible to implement rainwater management not only cost-effectively but even profitably, while saving scarce resources such as construction area and materials.
