IoT-Powered Drainage Monitoring
Industrial plants often face a hidden threat beneath their floors clogged underground drainage systems. When water levels rise undetected, it can lead to equipment downtime, material damage, and operational disruptions, especially during heavy rainfall or cleaning cycles.
To tackle this challenge, Macnman Technologies deployed an IoT-powered ultrasonic water level monitoring system designed specifically for industrial drainage networks. Using MacSync LoRaWAN Controllers, long-range gateways, and industrial-grade ultrasonic sensors, the system delivers continuous, real-time insights on underground water levels without requiring manual checks.

The Problem: Hidden Flood Risks Beneath the Plant
Even in well-managed industrial facilities, underground drainage systems are often overlooked until a serious problem surfaces. Manual inspection methods were unreliable, slow, and unsafe for maintenance teams — leading to delayed responses and unpredictable outcomes.
Blocked Drains
Sediment buildup and industrial waste caused unexpected clogs, leading to water overflow and flooding during cleaning or rainfall.
Manual Monitoring
Maintenance teams had to physically open chambers to check water levels — time-consuming, risky, and inconsistent.
No Real-Time Visibility
Without continuous monitoring, drainage health could only be guessed, not measured.
Safety Concerns
Standing water near power units and control panels created electrical hazards and unsafe working conditions.
Proposed Solution: Smart Water Level Monitoring & Automated Pump Control with LoRaWAN
To solve the recurring drainage overflow issues, we introduced a fully automated IoT solution that not only monitors underground water levels but also activates pumps automatically based on real-time sensor data.
The integration of Ultrasonic Sensors, MacSet LoRaWAN Controllers, and intelligent logic control ensures uninterrupted operations and proactive flood prevention — all without manual intervention.
- 01
Ultrasonic Water Level Sensors
Industrial-grade ultrasonic sensors detect the exact water depth in underground drainage chambers, unaffected by debris, foam, or humidity.
- 02
MacSet LoRaWAN Controller
Each controller receives sensor data and triggers the connected pumps automatically when the water level crosses a defined threshold.
- 03
Automated Pump Activation
Smart logic ensures pumps start and stop precisely when needed — preventing both overflow and dry running, optimizing energy use.
- 04
LoRaWAN Gateway Connectivity
All controllers communicate wirelessly to a central LoRaWAN gateway, which sends real-time status updates to the cloud dashboard
- 05
Real-Time Alerts
Supervisors get instant notifications when pumps activate, water levels rise abnormally, or any fault occurs in the drainage system
- 06
Maintenance Planning
Continuous data logging helps identify trends enabling predictive maintenance, early detection of partial blockages, and better pump lifecycle management.
