Heavy rainfall can create significant pressure on wastewater infrastructure. In combined sewer systems, stormwater and wastewater share the same network, so a rapid increase in rainfall can increase flow and raise the risk of Combined Sewer Overflow (CSO).
For wastewater operators, real-time data can provide better visibility before and during these events.
The Monitoring Challenge
A practical monitoring architecture needs to observe different types of data at the same time:
- 🌧️ Rainfall and weather conditions
- 💧 Water quality parameters
- ⚠️ Changing environmental conditions
- ⚙️ Operational conditions at the treatment or discharge point
Monitoring these data separately may make it harder to understand the overall situation. Combining them can provide a more complete operational picture.
Combining Weather and Water Quality Data
An automated rainfall monitoring solution can collect real-time weather information and rainfall data.
This allows operators to track current conditions and observe changes in rainfall intensity.
At the same time, a real-time water quality monitoring platform can monitor parameters such as:
- pH
- COD
- TSS
- DO
When these data sources are viewed together, operators can gain better situational awareness and identify changing conditions that may require operational attention.
Key Operational Benefits
1. Earlier Risk Awareness
Continuous monitoring provides current information instead of relying only on manual inspection or historical data.
2. Better Response to Heavy Rainfall
Rainfall trends can help operators understand when weather conditions are changing rapidly and prepare appropriate operational actions.
3. Continuous Water Quality Visibility
Real-time water quality data helps operators understand the condition of water during treatment and discharge processes.
4. Centralized Monitoring Data
Combining environmental and weather information can provide a more complete dataset for analysis, reporting, and operational planning.
5. Support for Environmental Management
Better monitoring visibility can help wastewater facilities manage environmental risks and improve long-term operational strategies.
Example Monitoring Workflow
A typical concept can be structured as:
Weather Sensors → Rainfall Data → Monitoring System
Water Quality Sensors → pH / COD / TSS / DO → Monitoring System
Combined Data → Operator Dashboard → Operational Decision
This approach does not mean that the monitoring system itself replaces sewer capacity planning, overflow controls, or regulatory requirements. Instead, it provides an additional layer of real-time information to support those activities.
Suitable Applications
This monitoring concept can be applied to:
- Municipal wastewater treatment plants
- Industrial wastewater treatment facilities
- Water utilities
- Sewer and drainage monitoring
- Environmental monitoring projects
- Facilities exposed to heavy rainfall
Build a More Proactive Wastewater Monitoring Strategy
Combined Sewer Overflow is a complex infrastructure and environmental issue. However, integrating real-time rainfall information with continuous water quality monitoring can help operators move from reactive observation toward more proactive operational decision-making.
