Every Tree Nurturing System (TNS™) node can be monitored in real time. BGI integrates Matter's SensAI sensing so performance is measured continuously against a calibrated baseline – turning maintenance from a fixed schedule into a data-driven, predictive response.
Matter sensor units are installed in vertical inspection pipes positioned behind each ESPPI and standard EnviroKerb. Each unit watches the flow into the inlet it sits behind.
Each Matter unit is configured with a baseline flow curve calibrated to the inflow capacity of the specific inlet it monitors – whether an ESPPI with a clean ARI filter or a standard EnviroKerb.
Real-time incoming flows are measured against that baseline continuously, drawing on established principles of smart-infrastructure monitoring for predictive maintenance and optimisation.
If measured inflows fall below the baseline curve, the system flags an inspection notification. The size of the deviation sets the maintenance response.
A single framework maps how far flow has dropped to the specific action required – so routine upkeep stays proportionate and most events are handled with a street sweeper.
| Severity level | Maintenance action |
|---|---|
| Minor deviation | Vacuum street sweeping throughout the zone |
| Moderate deviation | Lifting and pressure washing an ESPPI lid |
| Significant deviation | Replacing an ESPPI lid or ARI filter |
| Major deviation | Pressure washing a standard EnviroKerb |
| Critical deviation | Lifting out and replacing a standard EnviroKerb |
Zone-level consistency. With multiple Matter units across a zone, the system cross-checks them: if one unit flags while the others stay within baseline, the issue is likely localised; if several flag at once, it points to a zone-wide event needing broader maintenance.
The subsoil component of the TNS™ is often mis-read as a conveyance pipe. It isn't. Classified correctly, it sits in AS/NZS 3500.3 territory as a subsoil relief drain – not a QUDM minor/major conveyance outfall.
The line only relieves excess soil water once the TNS™ storage is exhausted. It is a relief mechanism for the saturated case – not a primary conveyance path that carries the storm.
Any relief flow leaves at seepage rates, after the runoff has already been filtered through the media. It is treated soil water being relieved, not raw stormwater being piped.
This is the same class of relief drain that road authorities themselves daylight onto batters and footpath flow paths. The classification is well-trodden, not novel.
Why it matters for approval: framed as a relief drain rather than an outfall, the TNS™ does not require a lawful point of discharge demonstration in the conveyance sense. We provide the classification basis and supporting detail as part of the specification package.
The Matter team is actively developing AI-enabled camera technology, co-located with the sensor units, to visually estimate incoming flow rate, spread width and water depth in the kerb and channel. Cross-referencing camera estimates against sensor data would create a redundant verification layer and open advanced analytics – including correlations between rainfall intensity, urban heat and flow.
Status: a development pathway, not a shipping feature. Matter's current sensing hardware is SensAI and FloodScan.
