MISTR Systems is wastewater data integrity software for industrial sites. It independently verifies what your effluent monitoring sensors report, across OCEMS and SCADA data, so a plausible-looking reading can't hide a failing pump, a stuck sensor, or a silent discharge breach.
Hardware-agnostic sensor verification: works alongside the SCADA / OCEMS system you already have. No new sensors to install.
Four national regulators, on four different continents, with no connection to each other, have independently confirmed the same failure mode: monitoring data that cannot be trusted without independent verification.
A sensor doesn't announce when it's wrong. A pump that's straining, a probe that's drifted out of calibration, or a flow meter that's physically stuck all keep reporting numbers that look perfectly normal — right up until a compliance sample, a fine, or a fish kill proves otherwise.
Regulators worldwide are responding by mandating more sensors and more continuous monitoring. That solves visibility. It does not solve trust — as one national regulatory body put it, an uncalibrated sensor just produces more false alarms, which erodes confidence in the very system meant to protect against failure.
Verification The MISTR Engine independently cross-checks what your equipment is actually doing — not a black-box guess, and not another sensor to install.
Self-Calibrating Learns each facility's real operating baseline automatically. No manual setup, no engineering knowledge required from your team.
Statutory Checks live readings against the correct jurisdiction's actual discharge limits — including facility-specific licensed limits where they differ from the generic default.
MISTR sits on top of whatever monitoring you already have. It doesn't replace your SCADA or OCEMS system — it checks whether what it's reporting can actually be trusted.
Upload a SCADA export or connect a live feed. No new hardware, no new sensors — MISTR reads the data your plant already produces.
Our proprietary engine quietly learns how your specific equipment behaves under normal conditions — automatically, with nothing to configure and no engineering input needed from you.
Every reading resolves to one of three states — compliant, verification mismatch, or statutory breach — with the reasoning shown plainly, not buried in raw numbers.
No raw SCADA tables to interpret — just a plain, defensible status for every parameter, viewable from a phone, a laptop, or a compliance officer's desk.
Every parameter MISTR checks resolves to one of three plain states — compliant, verification mismatch, or statutory breach — with the reasoning behind it, not just a number.
Illustrative preview based on our verification logic — not a live product screenshot.
Four reasons plant managers can deploy this quickly, and regulators can trust the result.
Works with the sensors and SCADA/OCEMS systems you already have installed.
Subscription-priced software, not a capital hardware purchase.
Grounded in proprietary, independently-verifiable logic — not an opaque model no one can explain.
Jurisdiction-aware limit checking — starting with EU and Indian statutory frameworks, extensible to others.
The trust-in-monitoring-data problem is universal. Our go-to-market is not — we're proving the model in two markets we know deeply before expanding.
Our founder's direct cross-border experience across both regulatory environments — EU/EPA standards in Ireland and CPCB standards across India's dense industrial base — shapes our initial pilot markets.
This is a deliberate starting point, not the limit of the opportunity: the underlying data-integrity problem is the same everywhere continuous monitoring is mandated.

The EPA says roughly half of these compliance failures come down to operational performance, not just ageing infrastructure — the exact gap independent verification is built to close.

Read the report →CPCB's own directive: get continuous monitoring installed and reporting properly, or face closure — the mandate is arriving faster than most facilities' ability to trust what those systems report back.
Read the report →Every plant we've spoken to has the same quiet fear: a number goes wrong, and someone has to answer for it — usually the person who trusted the sensor, not the sensor itself.
MISTR started with one uncomfortable observation, seen from two very different regulatory worlds — India's dense industrial base and Ireland's compliance-driven water sector: the equipment doing the reporting is rarely the equipment being checked. Everyone assumes someone else is watching the sensor. Usually, no one is.
So we built one thing, and only one thing: an independent way to verify what your monitoring equipment is actually telling you — before a regulator, an auditor, or a fish kill does it for you.

Wastewater data integrity means being able to trust that the readings a plant reports (flow, pH, COD, BOD, TDS and similar) reflect what is really happening. MISTR Systems checks whether each reading is possible, whether related measurements agree with each other, and whether a sensor looks stuck or is missing data.
Regulators are moving from periodic sampling to continuous online monitoring. In India, 17 categories of highly polluting industry are required to stream effluent data to the Central and State Pollution Control Boards 24x7, and the government has reported closure orders for units that did not comply. When data goes straight to the regulator, a faulty sensor becomes a compliance risk, not just a maintenance issue.
OCEMS (Online Continuous Emission/Effluent Monitoring System) is the system Indian industries use to send live monitoring data to the pollution control boards. The regulator sees whatever the sensors report, so a stuck, drifting or badly calibrated sensor can make a plant look non-compliant, or hide a real breach.
No. MISTR is a verification layer that sits alongside the OCEMS or SCADA system you already have. It is hardware-agnostic and needs no new sensors. It checks the data your existing equipment produces.
It flags readings that repeat unchanged, values that are impossible, missing or non-numeric entries, and measurements that contradict each other. Every flag comes with the reason and the affected rows, and anything that cannot be checked is labelled "not checked" instead of being guessed.
Today MISTR includes India and EU limit presets, which can be edited to match a plant's own licence or permit values. Other jurisdictions can be added.
Any industrial site with effluent discharge obligations: textiles and dyeing, pharmaceuticals, chemicals, food and dairy processing, pulp and paper, and the ETPs and CETPs that serve them. We are starting in India and Ireland, with the Middle East and South-East Asia on our roadmap.
Plant and compliance managers, ETP and CETP operators, environmental consultants, and auditors who need to know that reported effluent monitoring data holds up before a regulator questions it.
MISTR is an annual software subscription per monitored site, with portfolio pricing for consultants and multi-site groups. There is no hardware to buy.
MISTR Systems is looking for its first pilot sites in India and Ireland. Email hm@mistrsystems.com to request a pilot walkthrough on a sample export from your plant.
If you operate — or advise — an industrial facility with effluent discharge obligations, we'd like to show you what a verified reading actually looks like.
