Radar-Based Urban Drainage & Flood Early Warning Solution
1️⃣ Industry / Medium / Environment / Installation Conditions
This solution is designed for urban drainage systems and flood monitoring infrastructure, including:
Environment:
- Sewer manholes / inspection wells
- Urban drainage pipelines
- Flood-prone low-lying areas
- Stormwater networks and pump stations
Medium:
- Rainwater, sewage, mixed wastewater
- High turbidity, debris, and sediment environments
Conditions:
- Fully submerged, humid, and corrosive underground environments
- No stable power supply in many locations
- Remote distributed monitoring points
Requires reliable, low-maintenance, all-weather monitoring
2️⃣ Customer Problems
In urban drainage and stormwater systems, operators face severe challenges:
- Heavy rain causes sudden “manhole overflow” and urban flooding
- Manual inspection is slow and dangerous
- Sensors easily clog due to debris and sewage
- High humidity damages traditional contact-based instruments
- No real-time visibility of underground pipeline conditions
- Delayed warning leads to flooding and traffic disruption
Result: urban waterlogging risks and inefficient emergency response
3️⃣ Solution: Radar-Based Smart Manhole Monitoring System
We provide a low-power radar water level monitoring system for drainage networks
Micro-Power Radar Water Level Sensor
- Non-contact measurement inside manholes
- Immune to mud, debris, foam, and condensation
- Works reliably in fully humid underground environments
- High stability during heavy rainfall events
Power Supply System
- Large-capacity lithium battery
- Optional solar-powered configuration
- Designed for long-term unattended operation
Low-Power 4G Communication Module
- Real-time data transmission to cloud platform
- Supports distributed city-wide monitoring networks
- Stable signal in underground environments
Urban Water Management Platform
- Centralized dashboard for all monitoring points
- Real-time water level visualization
- Automated threshold alarm system
4️⃣ Installation Position
Radar sensors installed inside:
- sewer manholes
- drainage inspection wells
- flood-prone pipeline junctions
Installation method:
- Top-down mounting inside manhole shaft
- Non-contact measurement toward water surface
- Fully sealed waterproof design
Data terminal:
- Installed in outdoor control cabinet or remote station
5️⃣ Results / Benefits
After deployment, cities typically achieve:
- Real-time monitoring of urban drainage network
- Early warning of manhole overflow and flooding
- Faster emergency response and pump activation
- Reduced reliance on manual inspection
- Improved urban flood control capability
- Visualized “city life line” water status dashboard
Enables smart city flood prevention and drainage automation
