1. Designation Installation for treating, storing and conveying rainwater for use as utility water or for treatment for percolation or passing into an outfall. 2. Summary 2.1 Objective The aim of the invention is low-maintenance and inexpensive treatment, purification and storage of rainwater for use as utility water in homes, industry, commerce and public buildings or for the purpose of percolation or passing into an outfall, taking into account frost-proofing, with low expenditure on maintenance, without parts which wear, with a regenerable filter, with a frost-dependent filling level, with a damming-secured overflow and compact construction. 2.2 Solution of the technical object The rainwater is purified by rapid sedimentation, filtration through a depth filter and subsequent slow sedimentation. The filter is furnished with a washable, removable filter packing and, by the special construction form, makes possible high filter cross-sectional areas with low structural volume. Variable overdamming makes possible frost-proof laying of the drains in accordance with standards, without loss of filling level in the storage. Devices for forming layers and flow guidance in the storage free the water from suspended matter before withdrawal by slow sedimentation. Variable maximum water level, depending on the external temperature, make the use of an enlarged storage volume possible in frost-free seasons. 2.3 Area of application The main use of the described installation is the treatment of roof run-off water for utility water purposes. The treatment of surface run-off water from sealed surfaces is equally possible. In addition, the rain run-off from sealed surfaces can be purified by this system prior to percolation or passing into an outfall. IMAGE
