What problem does SmartFlow solve?
Urban areas are increasingly vulnerable to stormwater flooding. Impervious surfaces — rooftops, roads, and pavements — prevent natural water absorption and funnel large volumes of runoff into drainage networks simultaneously. During heavy rain events, these networks are overwhelmed, causing street flooding, property damage, and combined sewer overflows. Traditional drainage was not designed for the intensity and frequency of modern rainfall patterns. SmartFlow addresses this by controlling stormwater at its source — the building rooftop — before it enters the drainage system.
How SmartFlow works
SmartFlow installs a compact hardware unit on building rooftops. Water depth sensors monitor accumulation in real time. A motorised valve controls the release of water into the drainage system. The on-site control module connects via cellular network to the SmartFlow cloud platform, which processes sensor data alongside weather forecasts and drainage capacity models. The system determines when to retain water on the roof and when to release it — balancing flood protection with structural safety. Building operators can monitor performance through a web-based dashboard. The entire system is installed in a single day without structural modification to the roof.
Where SmartFlow is used
SmartFlow is deployed across a range of building types and urban contexts:
- Commercial buildings with large flat rooftops where peak runoff volumes are highest
- Municipal infrastructure programmes coordinating stormwater management across multiple buildings
- Residential developments requiring regulatory stormwater compliance
- Green and blue roof installations requiring intelligent overflow management
- Industrial facilities with impervious roof areas contributing to localised flooding
What makes SmartFlow different
AI-driven stormwater control
Adaptive algorithms process real-time sensor data, weather forecasts, and drainage models to optimise retention and release timing automatically.
Rooftop monitoring
Continuous water depth and flow measurement on every equipped rooftop, with event-by-event performance logging.
Real-time infrastructure management
Cloud-connected platform enables remote monitoring, configuration, and coordinated control across building portfolios.
Data analytics for drainage systems
Continuous time-series data supports regulatory reporting, model validation, and evidence-based urban planning.
Frequently asked questions
Is SmartFlow a hardware or software product?
SmartFlow is both. The system includes a rooftop hardware unit (sensors and motorised valve) and a cloud-based software platform that provides monitoring, control logic, and analytics.
Does SmartFlow require structural changes to the building?
No. The system is installed on existing rooftops in a single day without structural modification. The motorised valve integrates into the existing downpipe infrastructure.
How does SmartFlow communicate?
The on-site control module connects to the SmartFlow cloud platform via cellular network. No building network access or IT integration is required.
Can SmartFlow be deployed across multiple buildings?
Yes. The cloud platform supports portfolio-wide monitoring and coordinated release scheduling across any number of equipped buildings.
What data does SmartFlow provide?
Continuous water depth measurements, flow rates, event-by-event retention performance, release timing logs, and system health diagnostics — all accessible via the web dashboard and REST API.
