Matrix

When the data runs out

The closer we get to the source of infiltration and inflow, the less data is typically available.

At pipe level, permanent sensors and continuous measurements are rare. Traditional investigation can therefore require extensive fieldwork to narrow down where unwanted water enters the system.

Matrix takes another approach.

Autonomous sensors move through the existing sewer network and collect data from inside the pipe as they travel. This creates the information needed to investigate parts of the system where operational data would otherwise end.

From measurement to location

Changes in temperature can reveal where external water enters the wastewater stream. Matrix records these changes together with the movement of the sensor through the network.

Movement data is combined with GIS information to reconstruct the sensor route, while temperature anomalies are analysed to identify likely infiltration points.

The results are presented as geographical heat maps, transforming measurements from inside the pipe into locations that can be investigated and acted on.

Key benefits

• Identify infiltration points – use temperature and movement analysis to identify likely infiltration points directly in the sewer network.
• No permanent instrumentation – collect pipe-level data without installing fixed sensors throughout the network.
• Non-intrusive investigation – investigate existing infrastructure without cabling, permanent installation or excavation.
• Turn measurements into locations – combine sensor movement with GIS data to connect anomalies inside the pipe to the physical network.
• Visualise the problem – use geographical heat maps to see where infiltration is most likely to occur.
• Target further investigation – focus fieldwork and measures on identified problem areas rather than investigating larger sections of the network.

Creating data where there is none

Digitalisation normally begins with data.

Matrix begins where that assumption stops working.

By combining autonomous sensing inside the pipe with GIS and advanced analysis, Matrix creates a new layer of information in parts of the wastewater system that are otherwise difficult to observe.
