Water represents life. And a pond at LIKO-Noe is alive, come and see. The retention pond is a source and reservoir of rainwater, and haven for larger or smaller animals at the same time. Seepage and evaporation of up to 99 per cent of rainwater is another indisputable advantage. You thus help your sewage system work better.

In the last twenty years, manufacturing and warehouse premises in the area of approx. 45,000 hectares appeared in our country. Every year, the rainfall on these areas is over 500 million cubic meters of water which has no place to soak and uselessly disappears through sewerage.

Water

Liko-NOE can capture and reuse all the water that is used in it.  The rain water is trapped in the retention pond and the waste water is pretreated thanks to the root waste water treatment plant. It is then used for irrigation, nutrition of the wetland facades or for flushing. Much of the water is also bound to lively wetland façade covered with plants. Due to the large volume of water, it perfectly balances the fluctuations of temperature and protects the building mainly against overheating. The water is collected in the retention lake that serves as a water reservoir for the whole company area in the dry season. The retention lake can also be used for accumulation of water during torrential rains.

Root waste-water treatment plant – roof & facade

The wetland roof and roof waste water treatment plant is a complex of water-saturated layers of materials placed on a flat roof which allows the growth of wetland plants. This formation has thickness of about 15 cm and together with water weighs approx. 150 kg/m. Water itself is not visible on the roof – its surface consists of gravel from which plants grow. Under a layer of gravel, a porous material is placed to which bacteria are attached who intensify the cleaning process. In the winter, the facade root water treatment plant is warmed up by the building heat, so that the cleaning process is not stopped even in the winter months. Waste water is dosed to the roof by the pump and overflows by gravity to the wetland facade. A facade purifier system consists of superposed stainless steel cartridges filled partially saturated with water. Wetland plants grow in the cassettes and bacteria live on the surface of a porous material, which increases the surface area for their placement and treatment efficiency in the system. The purified water flows into the evaluation shaft and, based on the measurement, it is determined whether the water has been sufficiently cleaned and can be used for flushing toilets or for irrigation or the process needs to be repeated  and water once again returned to the root water treatment plant. Besides waste water treatment, this wetland roof also reduces unwanted overheating of the roof cladding.
