29 RAIN WATER AND SNOW HARVESTING FILTERING SYSTEM HYDROSYSTEM 3000, FOR 3000 M 2 ROOFS QUALITY NORM FOR RIVERS (NVV) POLLUTED RAIN FIRST FILTER MIXING FACTOR NNV NORM Filtration of rain water can be done by a system like Hydrosystem 3000 from Helnor, which can filtrate rainwater from a roof of 3000 m 2. The filtration system is tested and installed a various places the past 10 years. It can remove heavy metals, hydrocarbons, road and combustion particles as well as oils, and can then provide cleaner water than when the water was entering the building. The water amounts harvested has been the input for calculating water consumption and cooling from indoor plants
