Sewage Monitoring Systems

Gravity Flow Sewage Disposal Monitoring Systems (GFSD)

Sewage Disposal Monitoring Systems are technologies and processes designed to track, manage, and optimize the disposal of wastewater. These systems help municipalities, industries, and facilities ensure compliance with environmental regulations, improve public health, and reduce operational costs.

Gravity Flow Sewage Disposal Monitoring Systems (GFSD) rely on natural slope and gravity to transport sewage, meaning monitoring must account for flow conditions, blockages, overflow risk, and manhole performance without the use of pumps.

Here’s a list of relevant product categories and specific example solutions produced by Cansense:

1. Manhole-Level Monitoring Sensors

Use Case: Detect overflow risks, blockages, and surcharge conditions in gravity lines.

ADS ECHO™ – Ultrasonic sensor that monitors depth in manholes and gravity lines.
IoT Manhole Monitor by SmartCover Systems – Provides real-time level monitoring and alarm for overflow prevention.
Xylem® Manhole Monitoring Systems – Solar-powered, wireless level sensors for remote sewer monitoring.

2. Flow Meters (Non-Invasive or In-Pipe)

Use Case: Measure flow velocity and depth in gravity sewer lines.

Teledyne ISCO LaserFlow – Non-contact, laser-based flow meter that measures velocity and depth.
Greyline AVFM 6.1 – Area-Velocity Flow Meter with submerged sensor for partially filled pipes.
Flow-Tronic RAVEN-EYE® – Non-contact radar flow meter designed for open-channel flow.

3. Water Quality Sensors

Use Case: Monitor contamination levels, chemical indicators of system health.

YSI EXO Multiparameter Sonde – Modular water quality monitoring for pH, turbidity, conductivity, and more.
OTT ecoLog 1000 – Groundwater/sewer monitoring sensor with cellular data logger.

4. Data Loggers & IoT Gateways

Use Case: Collect and transmit data from multiple gravity sewer sensors.

Trimble Telog Ru-35 – Rugged data logger for flow, level, and rainfall, used in gravity systems.
Libelium Smart Water Platform – Customizable IoT solution to collect and transmit sewer data.
HWM Wireless Data Loggers – Battery-operated, GSM-enabled devices with years of lifespan.

5. Monitoring Platforms & Dashboards

Use Case: Real-time insights, trend analysis, and predictive alerts.

SCADA + GIS Integration Tools – From vendors like Wonderware, Ignition, or Bentley OpenFlows SewerGEMS.
SmartCover RealTime™ – Cloud-based dashboard for manhole monitoring with predictive analytics.
Aquarius (by Aquatic Informatics) – Centralized data management for flow and water quality.
