SEWER MANHOLE MONITORING

MORE INTELLIGENT, EFFICIENT AND RESILIENT NETWORKS

"The products are very quick and easy to install, which enables us to give customers delivery and implementation times with a great deal of confidence, something we do not believe we would get with any other telemetry unit.”

Sewer blockages are the main cause of residential and urban flooding in the UK, especially in high-risk urban areas. Monitoring sewers in real-time allows resources to be deployed to the relevant areas quickly, ideally before any flood event.

Metasphere's Point Colour robust telemetry units connect with most sensors to provide timely updates on the status of sewer levels under manholes.

THE PROBLEM

Manholes and sewers have a finite capacity which is reduced by any blockage. When a sewer exceeds its flow capacity, spills into the local environment are highly likely. Water utilities have a duty and legal obligation to minimise the risk of uncontrolled discharges resulting from blocked sewers.

THE RISK

Uncontrolled sewer spills pose severe risks to the environment and public health. Each year flooding causes billions of pounds of damage to the UK and fines issued for sewer discharges are exponentially increasing.

THE SOLUTION

The most effective way to monitor and control the manhole levels is to record the effluent level in real-time via a remote telemetry unit.  When the levels are sufficiently high to pose a spillage risk, an automatic alarm is generated calling for action, so the infrastructure can be maintained or repaired in a timely manner, resulting in cost-savings through compliance and reputational maintenance.

HOW DOES THE METASPHERE
SOLUTION WORK?

Metasphere’s monitoring systems, using the Point Colour range, can take inputs from multiple sensors usually in the form of ultrasonic, radar and submersible pressure for this application measuring level and flow. These sensors are monitored at predefined intervals, relevant to both the site and the sensors being deployed.

Typically, the RTU is set to power up every 15 minutes and record and save a level reading. The data is then transferred to Palette, Metasphere’s data visualisation service, where users can view the received data or make use of both the email and SMS alarm functionality. The latter is particularly useful for receiving alarms out of hours. or the client’s own servers, usually daily.

Alternatively data can be transmitted to the client’s FTP or DNP3 servers, where subsequent alarms can be generated by the user, or data can be used to perform control functions.
