Compact Storage: the modular tank can be piled on pallets, one 40'HC container can hold 294.4 cubic meters.

Environmental protection: the modular rainwater tank can be made of 100% recycled pp material,after service life, the pp material can be recycled once again.

Money Saving: Compared with the traditional stainless steel and concrete pools, Doctor Rain's Rainwater Module reduces the time cost, transportation cost and later maintenance cost in many ways.

Doctor Rain Rainwater Harvesting Module is a part of the rainwater utilization system, which can effectively collect and store rainwater. Rainwater resources collected through Doctor Rain Rainwater Module can be used to wash toilets, sprinkle pavement, irrigate lawns, water landscape, and even be used for circulating cooling water and fire fighting water. It can alleviate the current shortage of urban water resources, and is an effective way to open source and save water.
