The first advantage of modular rainwater collection tank is that we can use it to build the underground rainwater collection system in any size, that is to say, we can build a very small underground rainwater collection system as small as less than 1 cubic meter, or we can build a large tank system as big as 1 millions cubic meter.
The second advantage is that the modular rainwater collection tanks is stackable, so it can save a lot of space in transportation, we can fill a 40 foot high cubic container with the tanks which can form an underground rainwater collection tank system than more 300 cubic meters, that can 80000 gallons of water.
The third advantage is that it is very easy to build the underground rainwater collection tank because of its modular design, we can build the tank very quickly. It requires no big installation machines, we can do it just by our hands.
There’s many other advantages of this modular rainwater collection over the traditional concrete tanks.
