Combined Sewer Overflow (CSO) Monitoring and Control System Solution

Real-time monitoring solution for combined sewer overflow discharge points using multi-band Doppler radar flowmeters for precise overflow measurement, storm overflow early warning, and pollutant discharge accounting.

Overview

Summary

Key Advantages

Multi-band Doppler radar non-contact measurement, stable operation during storm floods

Integrated radar + camera for synchronized overflow video and flow data collection

Automatic overflow event identification: level threshold trigger, flow reversal detection, velocity surge alarm

Linked with meteorological forecast systems, automatically enters high-frequency collection mode before storms

Complete CSO event recording: start/end time, duration, cumulative overflow volume, peak flow rate

Multi-level alarm push: SMS, APP, platform popup, emergency command display

Automatic annual/quarterly CSO discharge statistical reports in environmental reporting formats

Challenges

CSO discharge points lack monitoring capabilities, overflow frequency and volume cannot be quantified
Rapid water level rise during storms destroys or submerges traditional contact-type instruments
Complex overflow point environment with floating debris interferes with conventional measurement
Environmental regulators require precise data on overflow frequency, duration, and discharge volume
Lack of early warning mechanisms leads to passive, after-the-fact emergency responses

Results

100% automatic capture of overflow events with precise frequency and volume accounting
Non-contact measurement remains stable during storm flood conditions with >98% data completeness
Camera synchronously records overflow footage as video evidence for environmental inspections
Storm warning coordination triggers emergency response 30 minutes in advance, reducing overflow pollution by over 40%
Annual CSO discharge reports generated automatically to meet environmental compliance requirements

Solution Details

Combined Sewer Overflow (CSO) Monitoring and Control System Solution Overview

In combined sewer systems (CSS), when stormwater volume exceeds the interception capacity during heavy rainfall, mixed rainwater and sewage overflows through discharge points directly into rivers, causing severe water pollution. Combined Sewer Overflow (CSO) is a major challenge in urban water environment governance and a key focus of environmental inspections.

This solution deploys multi-band Doppler radar flowmeters at critical overflow discharge points in combined sewer networks for real-time monitoring and precise measurement of overflow events. The device integrates radar flow sensors with HD cameras, simultaneously recording flow data and on-site footage during overflow events, providing reliable data support for overflow frequency statistics, pollutant discharge accounting, and network scheduling optimization.

Through RTU remote terminals linked with the monitoring cloud platform, the system enables storm warning coordination, real-time overflow alerts, and emergency dispatch functions, helping drainage authorities shift from reactive response to proactive prevention.
