The sponge city means city can soaked up water like sponge. This kind of city would be able to maximize retain of rainwater. Specifically, it is provided a plurality of plots in the city district, with the construction of absorbent material, as a sponge, when the time of rainstorm, it become a water storage place.Whether it is the mud, grass, tree or lakes absorb a lot of rain. In this way, the water can be digested, avoid the flooding. When those rain be absorb by the sponge, The problem of water accumulation has also been alleviated.

The amount of rainwater can be used again, such as landscaping irrigation, garden water, toilet flushing, car washing, can alleviate the shortage of water resources situation in a certain extent.

Speaking of the sponge city, what I have to mention is Rainwater Harvesting Module, as the heart part of sponge city, Leiyuan GS-TANKs is devoted to Rainwater harvesting tank’s research and development. By this time, has developed into fifth generation— M2016S tank and M2016B tank.

M2016 series, Uniquely using the hollow circular column as the key supporting point, not only maximized the specific storage, but also enhance the bearing capacity to 45T/sqm. Structure more simple, transportation and installation more convenient.
