1. Project Overview

Rural drinking water safety is a major livelihood project vigorously promoted under the warm care of the Party Central Committee and the State Council, focusing on solving the drinking water safety problems of hundreds of millions of rural populations and tens of thousands of rural schools. Through recent years of practice, the project is actively constructing centralized water supply projects, promoting the goal of integrating urban and rural water supply. The current prominent issue is how to ensure that these small-scale water supply projects built at the village and town level can be truly affordable, well managed, and operate in a healthy manner to ensure drinking water safety. Not letting down the sincere love for the people of the central leadership. The application of modern advanced information technology to achieve automated control and information management of the water production process is the most effective way to ensure the effective performance of water supply projects.

Under the direct guidance of Sichuan Provincial Water Resources Department and Agricultural Water Resources Bureau, and with the strong support of municipal and county water affairs departments, the Institute of Intelligent Control of Sichuan University (Chengdu Wanjiang Gangli Science and Technology Co., Ltd.) gave full play to the special advantages of key universities, based on the technical achievements formed by long-term engagement in water conservancy informatization construction, and aimed at the actual needs of the project, especially developed the "highly stable, highly reliable, low-cost, easy to operate" automatic monitoring system suitable for the scale and characteristics of rural water supply projects, forming a full progressiveness and highly practical whole solution. Through the pilot implementation of water supply projects such as Shiziwan Water Supply Station in Anju District, Suining City and Fengyu Water Supply Station in Yanjiang District, Ziyang City, the system operates stably and reliably, with simple and convenient operation; Effectively reducing the failure rate of equipment operation, reducing material consumption, energy consumption, and operation and maintenance costs; Significantly improved management level and drinking water safety assurance capability, enhanced ability to respond to various accidents and malfunctions. The system has basically achieved the goal of pilot construction, providing a good demonstration for the healthy operation of rural water supply projects and ensuring drinking water safety.
