NDG RAIN WATER HARVESTING The optimized unit for rainwater harvesting. SYSTEM SUMMARY Our new technology can easily be installed underground, in the basement, garage or in the ground floor utility room. With NDG Rain Water System, the collected rainwater passes through the rainwater filter, also known as the hydraulic jump filter, is the innovation for roof areas ranging from 60m² to more than 15.000m². This hydraulic jump technology cleans itself automatically. The rainwater is pumped from a tank via a suction hose and is used internally for toilet flushing, in the washing machine and externally for watering the garden. The water volume is monitored by a fill level indicator.
