China News Service, Jinhua, November 27th (Zhang Bin Ge Mingrui) On the digital big screen, online monitoring equipment real-time monitoring found that: a water supply station in a township has fluctuating water quality.

The reaction mechanism is triggered immediately, and the real-time monitoring screen shows that the water purification equipment of the water supply station has automatically started to work... This is a scene that happened on the "Smart Water" urban-rural integrated management and control platform in Yongkang City, Zhejiang Province a few days ago.

  Yongkang is known as the "Hardware Capital of China".

Due to geographical constraints, the per capita water resources are only 40.1% of the national average, which belongs to the water-deficient counties (cities) in the abundant water area in the south.

In recent years, taking advantage of the province's opportunity to promote homogeneous drinking water across urban and rural areas, Yongkang has not only formed a more secure urban and rural water supply pattern, but also created an urban water "Internet of Things" in the context of digital reforms, and promoted integrated online management and control of urban and rural drinking water.

  From "drink with water" to "drink good water"

  "The Qiutang Water Supply Station can supply daily water for 4 nearby villages, with a daily water supply specification of 960 tons." A few days ago, the relevant person in charge told reporters at the Qiutang Water Supply Station in Huajie Town, Yongkang City. After a series of renovations and upgrades in recent years, The water supply station has been able to meet the water needs of more than 4,000 local villagers and migrants.

  As early as 2007, Yongkang launched the "Drinking Water Project for Tens of Millions of Farmers". Through the construction of 8 urban-scale water plants and 245 single (union) village water supply projects, basic rural tap water coverage was achieved.

However, with the passage of time, problems such as poor water purification equipment and unprofessional management of the water supply project in Shan (lian) village have led to the reduction of water supply guarantee rate and water quality qualification rate.

  In 2018, Zhejiang took the lead in proposing the rural drinking water safety goal of "uniformity of urban and rural areas and unified management at the county level" in the country.

At that time, the coverage rate of large-scale water supply in Yongkang's rural areas was 69%, and the tap water quality compliance rate was 75%. The improvement of rural water supply became a "priority".

  In order to allow both urban and rural residents to "drink good water", in 2018, Yongkang began to implement a large-scale water plant network expansion project, starting a tough battle for rural drinking water standards and standards.

  "It took us three years to invest 756 million yuan to build 10 urban and rural water plants, upgrade and renovate 79 Shan (lian) village water supply stations, with a total water supply capacity of 357,500 tons per day." said Li Hui, deputy director of Yongkang Water Affairs Bureau. .

  For this industrial city, the guarantee of water resources effectively activates population influx and economic development.

Compared with ten years ago, Yongkang's population has grown by more than 240,000, with an average annual growth rate of 2.91%.

During the "Thirteenth Five-Year Plan" period, the local GDP increased from 52.7 billion yuan to 64 billion yuan, and it has been ranked among the top 100 counties in the country in terms of comprehensive strength for 14 consecutive years.

  "Since the transformation of the pipe network in the village, every household in the village has used clean and safe water." Huang Xuexiong, a villager in Zhousan Village, Zhoushan Town, Yongkang City, said that the rivers in the village have also become clearer over the years.

  Li Hui said that at present, Yongkang has completed the renovation of 193 villages’ pipe networks and the installation of 430 sets of household water purification equipment, benefiting more than 250,000 people in the city.

Throughout Zhejiang, in 2021, the province will basically achieve the goal of "homogeneous drinking water in urban and rural areas".

  Create the "Internet of Things" for urban water affairs

  It is understood that in order to ensure the quality of drinking water in urban and rural areas, Yongkang has also strengthened the water quality testing and testing of water sources, factory water and pipe network end water, established and perfected large-scale water plant laboratories and water quality testing agencies, and realized online monitoring of major water quality indicators of urban and rural water supply projects. .

  An online integrated management and control of the "urban water Internet of Things" has begun to take shape.

  "By using information technology such as cloud computing and big data, we can use online monitoring equipment to perceive the operating status of urban and rural water systems in real time. Implement remote monitoring, online monitoring, real-time early warning, and smart supervision of the city's urban and rural water supply projects." said Xu Menghao, deputy manager of the Water Resources Company of Yongkang Water Investment Group.

  In April 2020, Yongkang took the lead in Zhejiang Province to start the construction of a unified management platform for the “five waters in one” of source water, water supply, water saving, drainage, and sewage treatment.

  Xu Menghao said that as a platform to undertake all water data in the city, the “smart water” urban-rural integrated management and control platform has launched 13 modules including digital cockpit and water plant informatization. Data docking of the village water supply station.

"By analyzing and comparing the real-time water quality data of various water plants and water supply stations, it is possible to judge their operation conditions and possible hidden dangers, and then'prescribe the right medicine'."

  At present, the "Smart Water" platform has been connected to the video surveillance data of some urban-scale water plants, Shan (lian) village water supply stations, urban low-lying points and water sources in Yongkang, and plans to collect rural sewage terminal water quality data and drainage pipeline network distribution maps. And real-time pipeline network status monitoring data, etc., to realize the entire process of monitoring from water production to end users to sewage treatment, and truly build a "one picture" of the entire water environment in Yongkang.

  The data shows that the operation of the "smart water service" platform is expected to save 33% of local labor costs, reduce the leakage rate of the pipeline network by 5% to 15%, and increase the annual economic benefit by about 20%.

  Zhu Zhihao, Secretary of the Party Committee and Director of the Yongkang Water Affairs Bureau, said that the local area has established an urban-rural water supply pattern with "urban-scale water plants as the main water supply and Shanlian Village water supply station as a supplement". The coverage rate of chemical water supply is 92.2%, and the water supply guarantee rate and tap water quality compliance rate of rural water supply projects exceed 95% (end)
