Is there a water treatment plant in Dongguan?

I know there are many water treatment plants in Mayong, and there is an industrial park in Xinji, where there is a water treatment plant called Quansheng and several workshops. There is also an industrial zone in Huayang Village, where there is a washing company called Deguanglong with twenty or thirty washing workshops. There is a water treatment plant called Yongmei in Yuliangwei, Qingxi Town, which is run by Hong Kong people. The washing water there is very advanced. Others have washing plants in Shijie, Gaochun and so on!
