They are also used in real estate and infrastructure construction for the controlled treatment of rainwater. AVALON post-absorption modules are made from recycled and durable polyolefin thermoplastic with a low environmental impact. AVALON modules are very easy and quick to install. The modules are stacked on top of a leveled layer of crushed stone, with their ends overlapping the previous one. End plates are installed at the ends of the module row, in which a suitable opening is opened for connecting the sewer pipe. A filter fabric is installed on top of the modules, which should extend at least 30cm beyond the sides of the module. An opening for the ventilation pipe is opened on the back of the module with a jigsaw in the space reserved for it and the ventilation pipes are installed in place.   16 \u2013 32 The thickness of the crushed stone layer under the module must be at least 25cm and it must also reach the sides of the modules at least 50cm wide and 25cm thick. If the soil is poorly permeable clay, the crushed stone layer can be extended, for example, into a ditch or slope, where the water led to the module slowly drains."}
