Chongqing Water Supply Company： Building a National Water-saving City with Digital Wisdom and Empowerment

    March 22nd, 2024 is the 32nd World Water Day, and March 22nd-28th is the 37th China Water Week. On the occasion of World Water Day on March 22nd, Chongqing Water Supply Co., Ltd. (hereinafter referred to as "Municipal Water Supply Company") held a series of public open days of World Water Day in 2024 with the theme of "giving priority to water conservation and promoting high-quality development".

    "Please come in" and "Go in" to promote water conservation and protection.

    On the afternoon of March 20th, the Municipal Water Supply Company launched the theme activity of "Persisting in saving water and giving priority to promoting high-quality development". User representatives from 11 enterprises and institutions, including Chongqing University, Sichuan International Studies University, Chongqing Nankai Middle School, the First Affiliated Hospital of PLA Army Medical University (Southwest Hospital), Yubei Road Street in Shapingba District, Chongqing Ronghui Hot Spring Industry Development Co., Ltd., were invited to walk into Shapingba Waterworks of the municipal water supply company, and visit the facilities in the plant, such as distribution wells, sedimentation tanks, V-type filters, sodium hypochlorite storage tanks, clean pools, secondary pump houses, etc., to learn about the technological process of making water from tap water.

    "By looking at the technological process of tap water production on the spot, I can understand the water quality guarantee measures and water supply service system of the municipal tap water company, which makes me more assured about the safety of drinking water." Mr. Wen, representative of Chongqing Ronghui Hot Spring Industry Development Co., Ltd. said.

    "Shapingba Water Plant has been put into operation since 1958 and has a history of 65 years. Since the establishment of the factory, it has closely followed the trend of scientific and technological innovation and industry development, effectively improved the city’s water supply capacity, and met the people’s demand for high-quality and healthy life. " Man Long, a member of the production department of Shapingba Waterworks, said that the current water supply capacity of the Waterworks is 200,000 m3/d, serving more than 1 million people.

    It is understood that in order to let more people know about the production process of tap water and cultivate the awareness of cherishing water resources, the Municipal Water Supply Company will also organize a "tap water school" activity, and the staff of the water plant will go into Renhe Street Primary School, Yucai Experimental School, Ertang Primary School in Sha District and Chongqing Business School to give lectures on tap water science.

    At the same time, Yuzhong District Water Plant, Heshang Shanshui Plant, Wellhead Water Plant and Fengshouba Water Plant under the Municipal Water Supply Company will carry out water supply business consultation, water quality knowledge publicity, soliciting opinions and suggestions, voluntary maintenance and other activities during World Water Day and China Water Week, so as to popularize the "Regulations on Urban Water Supply and Water Saving in Chongqing" and the knowledge of water saving and water use, and fully promote the establishment of "National Water-saving City".

    The level of water resources management has been further improved through the empowerment of digital intelligence.

    It is understood that since the expansion and transformation of Shapingba Waterworks in 2006, although some automation systems have been built, they have been in operation for 16 years due to imperfect functions at that time. In 2021, under the unified deployment of Chongqing Water Group, the municipal water supply company took the lead in carrying out the pilot demonstration construction of smart water plant in Shapingba Water Plant, mainly including the renovation of automation equipment and the pilot demonstration project of smart water plant (construction of transportation management platform).

    "This transformation completed the update of automatic control and monitoring equipment, and at the same time transformed the network to form an industrial control ring network, which improved the stability of the network and transmission, and re-established a set of SCADA control system." Na Xin, deputy secretary of the Party Committee and general manager of the Municipal Water Supply Company, said that after the transformation, the functions of remote one-step start-stop and automatic sludge discharge of the unit were realized, and most of the equipment was remotely controlled and monitored, and three advanced process controls were realized: intelligent dosing, intelligent chlorination and intelligent backwashing of the filter.

    According to reports, the intelligent transportation management platform enables operators to complete all-round monitoring of equipment; The 3D visual modeling of the platform can intuitively show the specific information of the main factory’s processes, pipelines and equipment, which is convenient for personnel to understand and master relevant business knowledge. At the same time, the platform can also realize the management functions of production data, equipment, work orders, videos, alarms and reports, improve the level of digital management and help digital transformation.

    Na Xin said that the smart water plant project of Shapingba Water Plant, as a pilot demonstration project of smart water plant of the municipal water supply company, has promoted the steady development of Shapingba Water Plant from "digitalization" to "intelligence". After the implementation of the project, the production, operation and management of Shapingba Water Plant have been greatly improved. (Wang Cailing)
