Heavy rainfall, long periods of drought, heat and flooding are all becoming increasingly common. Without proper rainwater management, these environmental factors can cause erosion and water pollution. Pipelife and Wienerberger develop solutions that combat flooding and, at the same time, make good use of the collected rainwater.

Careful management of water as a resource
Product presentation
Large conurbations with large areas of impervious surfaces are especially at risk from the sudden onset of heavy rain. Such impervious surfaces do not allow natural seepage, and drainage systems are not designed to cope with sudden, peak flows. Pipelife has dedicated itself to finding solutions to this problem and developed the Raineo® system for rainwater management.
The system is installed inconspicuously underground. It has also been designed to enable planners and users to cope with a wide range of demands, in accordance with the size and purpose of the built area, the degree of contamination of the water or the nature of the soil.
Cutting-edge technology for the environment
Raineo® is a modular – and, therefore, highly flexible – system, which captures rainwater, filters out any impurities, and then, depending on requirements, either releases it slowly to seep into the earth or temporarily retains it in so-called “Stormboxes”.
These are stackable, water infiltration boxes with a simple connector system. They store the rainwater so that it is available for further use in sanitation, cleaning or irrigation. The system therefore facilitates the collection of usable water and also the return of rainwater to the water cycle through infiltration, maintaining the natural function of the soil.
Natural ecopaving
Wienerberger has developed another innovative building material for sustainable urban drainage systems in the form of Passaqua (NL)/Aquata (UK). These clay paving stones with spacers for 6 mm wide joints comply with modern planning requirements.
Although the paving stones themselves are not permeable, the wide joints allow rainwater to drain away easily. In the space beneath the paved surface, the rainwater is filtered, cleaned, and collected before being released in a controlled manner into the soil or drainage system. This makes it easier to maintain the water table and reduces the risk of flooding. It also reduces the proliferation of algae, moss, and weeds.
These clay paving stones have been designed with the unique style, look and durability of traditional paving stones, but are also available in a variety of colours. These premium quality paving stones are strong, durable, and slip-resistant, making them particularly suitable for patios, driveways, paved emergency access routes, public footpaths, cycling paths and car parks.
