Rainwater storage

This is Water N Future's exclusive water tank for rainwater collection.

Unlike general water, rainwater requires special care.

Rainwater contains various particles and dust, as it is collected from rooftops. Frequent cleaning is required as sludge is deposited in water tanks.

Water N Future's exclusive water tank for rainwater collection is low in height for easy cleaning. Sludge is naturally discharged through water inlet and outlet on the bottom. Water N Future's exclusive water tank for rainwater collection consists of multiple small-sized water tanks connected to each other. With it on rooftop, you do not have to worry about the load.

Induction filter, installed together with Water N Future's exclusive water tank for rainwater collection, drops large particles to the bottom, and induces rainwater only. Therefore, it is never clogged.

Water N Future's exclusive water tank for rainwater collection adjusts the water level of the tank. Therefore, rainwater in the tank does not overflow. Quality rainwater can be collected through double filtration.

Water N Futures' exclusive water tank for rainwater collection eliminates initial rainwater. Open the valve to eliminate murky initial rainwater.
