IoT Monitoring
for Water & Wastewater Plants

Real-time, verifiable monitoring for water treatment plants, desalination plants, sewage and effluent treatment plants across India and the Middle East. Wateria connects sensors and PLCs to a secure industrial IoT cloud platform that turns every reading into live dashboards, alerts, tracked corrective actions and audit-ready compliance reports.

WHY CONTINUOUS MONITORING

A Grab Sample Is a Snapshot. Compliance Is 24×7.

Periodic sampling only shows the moment the sample was taken. Continuous data captures the whole day, including night-time shutdowns, peak loads and slow drift that a monthly visit can miss.

Illustrative profile, not measured data.

  • Night-time shutdowns go unseen

    Blowers switched off to save power leave no trace in a daytime sample.

  • Logbooks cannot prove operation

    Energy draw, equipment run-hours and dissolved oxygen move together only when treatment is really happening. A plant cannot fake all three.

  • Thousands of readings, not a few

    One connected sensor logging every 15 minutes adds more than 35,000 readings per parameter a year.

APPLICATIONS

HOW IT WORKS

Two Paths. One Outcome: Every Plant Online.

Sensors → PLC → IoT data logger → Cloud → People

If the plant already has a PLC, an IoT data logger reads it over standard industrial protocols such as Modbus and the plant is typically live within days. Control logic stays untouched; only data flows out. Manual plants are first automated with a PLC panel, motor starters and essential sensors, typically in 2 to 4 weeks. Timelines are confirmed after a site survey.

      WHAT WE MEASURE

      Parameters Monitored by Plant Type

      Discharge and product-water quality show the result. Process signals such as dissolved oxygen, run-hours and energy prove the plant was genuinely operated. Instrumentation is scaled to plant size, risk and consent conditions.

      Indicative guide. Enforceable limits are those in each plant's consent or permit, and the platform is configured to them. Online BOD, COD and TSS analysers are fitted where specified by consent conditions or plant size; other parameters are verified by laboratory analysis.

      SMART ALERTS

      Sensor Triggers That Matter

      Alert classes are aligned to CPCB's revised online monitoring alert protocol (exceedance, stuck values and connectivity), plus operational evidence that shows whether a plant is really running.

      TriggerDetection Logic (Indicative)Immediate ResponseAlert Class
      Discharge exceedanceOutlet pH, BOD, COD or TSS beyond the consent limit, sustained for 15 minutesOwner and Wateria alerted; corrective task created automaticallyExceedance
      Suspected bypassDischarge flow while blowers or pumps are off, or inlet–outlet imbalance beyond toleranceHigh-priority flag to owner and WateriaOperational
      Plant not operatingBlower off for more than 30 minutes in operating hours, or aeration DO below 0.5 mg/L for 2 hoursOperator alert; escalates if unresolvedOperational
      Disinfection failureResidual chlorine below set-point, or UV lamp faultAlert plus chemical stock checkExceedance

      Calibration due / tamperCalibration overdue, or sensor or panel disconnectedTask plus audit-log entryData integrity

      Thresholds and timings are indicative; final values are set per each plant's consent conditions and agreed with the plant owner and, where required, the regulator.
