1. Project background:

The rural water supply project in Linquan County involves 31 towns and 1 industrial park. After the completion of the rural drinking water safety project in 2018, the county retains 89 centralized rural water supply projects, including 87 water plants with a scale of tens of thousands of tons. There are 2 water plants below.

At present, the water quantity and quality of water plants of various scales can meet the standard requirements, the water supply facilities are basically complete, and the leakage rate of the pipe network is basically 10-15%. However, in recent years, with the transformation and expansion of the Linquan County Agricultural Drinking Project and the development of industry informatization, problems such as the lack of professional knowledge of relevant managers, the single traditional management mode and the backward methods have gradually been exposed.

In Linquan County, the agricultural and drinking water pipelines in the current agricultural and drinking project area are still managed by manual means, and the data is unclear, and the sharing is poor. At the same time, the water plant established before 2013 is limited by construction conditions, plant equipment and Pipe network inspections mainly rely on manual inspections, lack of professional inspection systems and equipment inspection procedures, low management efficiency, and equipment failures that cannot be responded to and resolved in a timely and effective manner. There are currently 89 water plants in the county, and the scale of water plants is relatively large. Project management tasks are arduous, management departments and sites at all levels cannot be effectively connected, and information islands exist in the operation of various water plants. In case of water supply failure, the ability to deal with problems is insufficient, resulting in a lack of guarantee for the safe operation of water supply.

Based on the above reasons, Linquan County hopes that through the construction of this information system project, the information management level of the overall agricultural and drinking water supply project in Linquan County will be improved, and the water supply service capacity will be improved. The Linquan County information system construction plan aims to use GIS technology to build an efficient, reasonable and practical water supply management service platform, to monitor the real-time parameters of the water source water plant, the operating status of process equipment and the operation of the pipe network through information methods, and to enhance the temporary The operation and supervision capabilities of the Quannong Drinking Project will improve the management service level and ensure the safe, reliable and economic operation of water supply.

2. Project status:

At present, there is no unified supervision of the township water plants within the jurisdiction of Linquan County, and the contracting system is mainly implemented among the various water plants. Because the production process of the water plant is relatively simple, and the number of supply users for each water plant is small. Therefore, the personnel on duty in the water field can be counted in single digits.

During the investigation, it was discovered that each water plant was equipped with a host computer environment built by Gemheader, whose functions were mainly traditional monitoring functions. There are few data collections between water plants, and there is a lack of data transmission channels or other message transmission channels with the water affairs bureau or the centralized control center.

Township water plants in Linquan County use groundwater to supply water to users. After water is collected from the ground, it is directly subjected to fluoride removal and chemical dosing treatment (some water plants do not remove fluoride), flows to the clean water pond, and is finally delivered to township residents through pressure treatment. The water quality parameters can only be displayed inside the water plant after being obtained, and cannot be obtained by external units.

There is no dispatch function between Linquan County and the water plants of various towns.

At present, the management of water plants is limited to manual management, and a comprehensive and effective all-weather management system has not been established.

3. Construction content:

The main content of smart water construction is to build a water supply pipe network GIS system, check the pipe network and related equipment in the Linquan County agricultural and drinking project area, and store them, and enter and update it to the GIS system in time to fully grasp the water supply information resources In this process, through systematic training, help grassroots business personnel gradually improve their knowledge of informatization, realize the training of management personnel, and improve the overall quality of personnel.
