Clogging-Regime Monitor for Stormwater Sand Filters
A monitoring service that tracks each stormwater sand filter's operating point in dimensionless coordinates computed from flow and head-loss telemetry, and alerts maintenance crews when the filter drifts into a clogging-prone regime before it hydraulically fails.
Concept
Stormwater sand filters fail by clogging, and the evidence base is itself conflicted on the trade-off between media depth and clogging formation — so rules of thumb learned at one site do not transfer to filters of a different depth or size. This is the theme's stated open gap: a clogging predictor for sand filters. Paper [0] supplies a method to fill it: the characteristic numbers describing a technological process, and the similarity criteria of that process, can be obtained statistically.
The product is a monitoring add-on for installed filters:
- Read existing telemetry — influent flow, head loss across the media, storm-event counts, turbidity where available.
- Continuously compute the filter's characteristic numbers (e.g., cumulative solids load per media volume, hydraulic loading relative to design, head-loss growth normalized by runtime) using the statistical derivation approach of [0].
- Because the numbers are dimensionless, clogging thresholds learned on one filter transfer to filters of other depths and sizes — directly attacking the depth-vs-clogging conflict that makes site-specific heuristics unreliable.
- Alert the maintenance crew when the operating point crosses into a regime that has historically preceded clogging, so media cleaning or replacement is scheduled before surface ponding or bypass occurs.
Why now
Paper [0] demonstrates that characteristic numbers for describing the technological processes of industrial technical systems, and the similarity criteria of those processes, can be obtained with a statistical approach — giving a data-driven way to express filter operation in size-independent coordinates. The theme evidence records an unresolved conflict between media depth and clogging formation in stormwater filtration, which is precisely the situation where dimensionless criteria are the correct instrument: they let a utility pool clogging observations from heterogeneous filters into one transferable regime map instead of unreliable per-site rules of thumb.

AI assessment
A highly focused predictive maintenance tool that solves a specific engineering conflict (media depth vs. clogging) using dimensionless analysis to enable cross-site scalability.
- Evidence strength 3/5
- While the application to sand filters is well-supported by papers [3] and [4], the core methodology relies on a very brief, generic abstract [1] regarding statistical characteristic numbers, which is a leap in application.
- Market pull 4/5
- Municipalities and infrastructure firms have a clear, urgent need to reduce manual inspections and prevent hydraulic failure of stormwater assets.
- Novelty & moat 4/5
- Unlike InfilAudit (which is a field audit) or Adaptive Infrastructure Health Monitor (which is a general dashboard), this uses a specific mathematical mechanism (dimensionless coordinates) to solve a known technical gap.
- Feasibility 4/5
- The MVP requires only a software layer to process existing telemetry data, making it highly feasible for a small team to build without new hardware.
- Wedge clarity 5/5
- The wedge is extremely sharp: a monitoring add-on specifically for stormwater sand filters to predict clogging.
- Simplicity / focus 5/5
- The idea avoids 'platform' creep, focusing on a single calculation and alert mechanism for one specific asset type.

Business analysis
The PESTEL analysis reveals a strong alignment with current municipal digital transformation trends and environmental mandates, though it faces a challenging economic landscape due to the slow procurement cycles of government agencies. The core value proposition hinges on solving a specific technical conflict (media depth vs. clogging) using a novel statistical approach to create scalable, dimensionless monitoring.
