The same layer of drainage can solve this problem.

In this context, through the effort of our technical staff, our company research and development of drainage system become a new kind of environmental protection, water saving and high efficiency of drainage system, obtained the national patent certification, and has fully independent intellectual property rights, in the process of industrialization of cooperation and social benefit and economic benefit is remarkable market.
