Roof construction for production of dew for creation of user water

摘要

The user water storage tank only feeds back its overflow to the roof gutter. For the storage tank the space and static conditions between the roof (1) and the roof base (8) over the outer wall (6) are used. The water inlet (4) into the storage tank (5) is conducted over a sieve surface, which cleans itself when the tank is full and the overflow flows out of the inlet groove (4) into the roof gutter (9). The user water originating from rain and dew is fed to the washing and toilet apparatus, which do not require high pressure water.
