Many inspection technologies provide a ‘snapshot’ of a particular measure at a particular point in time. This is valuable information but provides no indication of how the measure varies hourly, weekly, seasonally, or whether there is a long-term trend.

Many of the technologies used by Assetlife Alliance can be installed for a defined period, or permanently which provides a very rich source of data

The information can be used to identify events that are adversely impacting on the assets, the service or the environment, to track the source of the event and to progress remedial actions. The data can be transmitted or collected locally on a data-logger.

The use of satellites and Artificial Intelligence (AI) is a rapidly evolving monitoring technology. A range of sensors takes regular images of the network and AI is trained to recognise changes that are occurring. This can detect long term trends and also provide early warning of changes that might generate a service disruption.

Examples of monitoring applications include:

• Monitoring real time (24/7) or daily monitoring
• Customised programs and technologies including leak detection
• Field data collection for hydraulic model calibration
• Geospatial Artificial Intelligence for network prioritisation

• Acoustic, pressure and flow change analysis
• Data interpretation, establishing system profiles and alarm thresholds
• In situ meter verification services to determine accurate flow demand and profile
• Reservoir level and SCADA monitoring

• Pressure management
• Energy efficiency monitoring
• PRV installations and monitoring
• PMA/DMA validation
• GNSS GPS
• Infiltration and Inflow investigations and analysis

• Monitoring transient pressures and flows in water supply networks
• ‘Hearing’ the emergence of leaks
• Detecting sewer flow changes and overflows in storm events
• Identifying intermittent pollution events
• Satellite scanning of networks
