Underground water storage module
The storage box is made up of polypropylene plastic module cells, forming an underground storage pond, according to the requirements of the project, wrap anti-infiltration earthen cloth or one-way infiltration
earthen cloth around the pond, forming the two different types of water storage pond and infiltration water regulation pond. The installation of water storage box is convenient, with large bearing capacity. Do not breed mosquitoes and flies and algae to ensure water quality, and after the provisional construction area is put into use, it can be disassembled and removed to other regions for continual use. The equipment applies to the rainwater collection and utilization in large buildings, residential blocks, industrial parks, squares and workshops.
