Smart Manhole Covers

SUEZ wastewater monitoring systems never rest. We have you covered every inch of the way across your stormwater and wastewater collection systems. Even our smart manhole covers for wastewater monitoring keep guard. SUEZ’ sensor-equipped Smart Manhole Covers actively manage collection systems, reducing sewer backups and sanitary sewer overflows (SSOs).

3 Key Benefits of a SUEZ Smart Manhole Cover

  • Reduces Sewer Overflows
  • Provides Remote Wastewater Level Monitoring and Data Collection
  • Reduces Costs

Occasional unintentional discharges of SSOs from municipal sanitary sewers occur in almost every system. Smart Manhole Covers actively manage collection systems by monitoring water levels with sensor-equipped manhole covers. Smart Manhole Cover sensors are typically installed within manholes that have a history of SSOs or that are close to sensitive locations, such as hospitals, schools and beaches.

Real-time wastewater monitoring provides SUEZ with early warning and the time necessary to prevent failures. The Smart Manhole Cover technology also allows SUEZ to find the sources of Inflow and Infiltration (I&I) which are a major concern for municipal utilities.

How Does SUEZ' Smart Manhole Cover work?

The wastewater monitoring device is attached to the sewer cover’s underside and a hole is drilled in the manhole cover to install the antenna. The unit is a dual wastewater level sensor, composed of an ultrasonic sensor that measures the level of the water when the sensor is not submerged, and a pressure transducer that measures the level of the water when the sensor is submerged.

The Smart Manhole Cover sends data via satellite to a secure web platform, where technicians monitor water levels and remain poised to dispatch emergency crews at any hour in case of rising water levels.

Alarms & Standby Crews Allow for Immediate Action

SUEZ can set up wastewater level sensor alarms based on the water level within the system. Alerts are sent directly to standby crews via email or text, as well as to the web platform.

Two types of maintenance can be performed based on the data collected:

  • Emergency action, such as high-pressure jetting, can be conducted to prevent an SSO once a high wastewater level alarm is triggered.
  • Preventive action, such as pipe inspection, can be conducted if the water level is trending up over time. Inspection is conducted until the origin of the problem is identified and remediated.

When used with additional applications, the data collected can be used to calculate flow rates and overflow volumes of CSOs, and to visualize the real-time impact of rainfall or tide on water levels.

This steady stream of data, gathered and analyzed by our experts and delivered to you, means that no one has your collection system covered like SUEZ and our Smart Manhole Covers.
