    THUA THIEN HUE CONSTRUCTION AND WATER SUPPLY STASE ONE MEMBER CO., LTD

    Advanced Methods Attract Considerable Attention from Water Utility Personnel Throughout Vietnam

    The system began operation in June 2015. Detailed evaluation of data accumulated by Harmonas-DEO and full-fledged implementation of measures for correcting any glitches discovered through evaluation have not yet started, but the system has already achieved results.

    “During two years of implementing the project, including all four areas, the automatic chemical dosing control at Quang Te 2 WTP has achieved definite results which the technical team of HueWACO has assessed using the advanced technologies of Azbil as well as the experience of the experts of Yokohama Waterworks Bureau (YWWB) in Japan. The automatic chemical dosing control system has helped to determine the appropriate amounts of chemicals and also has dramatically reduced the time and effort required to add in the chemicals, which contributed to better control of water quality at the plant,” says Mr. Tuan.

    Chau Ngoc Long, Manager of Planning in the Technical Department of HueWACO comments, “In this project, regarding the SCADA system at Quang Te 2 WTP, owing to the support from the JICA project, Azbil Corporation, and YWWB, HueWACO was able to successfully connected the automatic chemical dosing control system to the SCADA system. HueWACO has also invested much additional machinery and equipment to ensure optimal system operation. I think this is the first success area of this project.”

    A seminar on the Vietnam-Yokohama Safety Water Supply Management Project was held in June 2015 at the head office of HueWACO. In the seminar, details of efforts in the four technical areas, including the construction of the Quang Te 2 system, were presented.

    “The seminar was attended by about 200 water utility personnel from 40 municipalities across Vietnam. The case study of the system built at the Quang Te 2 WTP attracted a great deal of attention from the participants and was highly evaluated,” says Mr. Long.

    HueWACO plans to install a similar system at other water treatment plants operated by the company.

    Mr. Nam states, “In the future, HueWACO will establish a central control center for monitoring and operation of the water supply system. In these efforts, we look forward to Azbil’s technical assistance and support for human resources development as well as machinery.”

    Analyzers determine the concentration levels of chemicals, degree of water turbidity, and water quality by analyzing the water obtained through conduits, and then transmit the data to Harmonas-DEO, which implements the results of control calculations.

    Training was held at Azbil’s Fujisawa Technology Center for the three engineers dispatched from HueWACO.
