Guangzhou Water Supply Company is a state-owned water supply enterprise integrating the production, sales, service and diversified operations of tap water. It was formerly known as Guangdong River Water Company (Xicun Zengbu Water Plant) and was the first water plant in Guangzhou. At that time, only tap water was produced. After 1949, it successively produced water pipes and water meters, and took on the management of water distribution pipe networks and business operations.

Hailian equipped customers with a dual-system solution of electric telescopic doors and electric anti-terrorism lifting columns. It plays a decisive role in preventing illegal intrusion of vehicles and people.
