Urban management work is at the forefront of people's livelihoods, characterized by poor working conditions, heavy workloads, and demanding tasks. The cleaning and dredging of septic tanks and sewage wells, as a major part of this work, involves the living environment of thousands of households. Due to the inability to provide early warnings for abnormal changes in water levels in septic tanks, sewage wells, and pipelines, response efforts are often delayed. Typically, action is taken only after overflow incidents occur and citizens call for help through hotlines. When such situations arise, they lead to severe environmental pollution and the risk of disease transmission, causing widespread complaints among residents and increasing the workload for cleaning personnel.

The "Septic Tank Liquid Level Monitoring and Alarm System" is a practical application of "Internet+" in urban public services. It transforms the traditional management model of "manual inspections + hotline assistance" for urban waste management by relying on overflow monitoring terminals and an intelligent management service platform. This shift changes the approach from post-incident response to preemptive prevention, establishing an intelligent monitoring and early warning mechanism to prevent septic tank overflows.
