Continuous colour monitoring.
Stop discolouration before
it reaches the tap.

Real-time apparent and true colour monitoring. Detect the iron, manganese, organic matter and treatment by-products that drive discolouration, before a visible event becomes a wave of complaints.

Example readings for illustration purposes

What you can’t see
is already costing you.

Reactive call-outs

Issues are flagged after damage is done, not before it starts. Every delayed alert is a cost you didn’t have to carry.

Fragmented compliance

Manual records, missed checks, and audit gaps across sites. When an inspector asks for evidence, the scramble begins.

Hidden drift

pH, chlorine, or turbidity can shift for days or weeks before anyone notices. Without real-time monitoring, you’re always reacting.

Continuous monitoring.
Instant alerts. Full audit trail.

Three connected layers that turn raw sensor data into actionable intelligence, automatically.

1. Monitor

Connected sensors stream real-time data across all parameters, 24 hours a day. Cellular and LoRaWAN telemetry with encrypted payloads.

2. Alert

Threshold breaches trigger instant SMS, email, or app notifications. Escalation rules and role-based routing ensure the right person acts.

3. Respond

Cloud dashboards give your team the data, trendlines, and records they need, instantly. Every reading logged, every action auditable.

Every parameter.
One connected system.

From standard chemistry to full-spectrum UV-Vis sensing, AQUAIOT covers every dimension of water quality your operation demands.

SPS-pH Water Quality Sensor
pH
SPS-pH Sensor

Continuous acidity and alkalinity monitoring. Detect corrosion risk, Legionella-risk conditions, and treatment performance drift.

Optimal drinking water pH: 6.5–9.5. Drift outside this range signals treatment failure or infrastructure issues.
SPS-T-SC1 Turbidity Sensor
Turbidity & Suspended Solids
SPS-T-SC1 Sensor

Detect particulate contamination, filter breakthrough, and process upsets in real time.

Turbidity spikes are often the first indicator of pipe disturbance, contamination ingress, or treatment failure.
SPS-CI Free Chlorine Sensor
Free Chlorine
SPS-CI-C Sensor

Continuous disinfection residual monitoring. Ensure treatment efficacy without manual sampling delays.

Chlorine residual below 0.1 mg/L creates microbial risk. Continuous monitoring catches drops before they become incidents.
SPS-DO Dissolved Oxygen Sensor
Dissolved Oxygen
SPS-DO Sensor

Monitor oxygen levels critical for biological process control, aeration efficiency, and environmental compliance.

Low DO in wastewater systems indicates biological stress; in distribution it can indicate contamination ingress.
SPS-EC Conductivity Sensor
Conductivity
SPS-EC Sensor

Track dissolved mineral content and detect contamination events, cross-connections, or treatment changes in real time.

Sudden conductivity changes are a rapid indicator of intrusion, saline ingress, or chemical contamination.
SPS-F Full Spectrum Water Quality Sensor
Full-Spectrum UV-Vis
SPS-F SpecSens Sensor

Specsens UV-Vis sensing at the edge. Detect organic load, humic substances, and complex contamination signatures beyond single-parameter sensors.

Full-spectrum sensing captures richer water quality signatures, ideal for source water characterisation and treatment optimisation.
SPS-Color-C Colour Sensor
Colour
SPS-Color-C Sensor

Detect apparent and true colour changes that may indicate natural organic matter, iron, manganese, or treatment by-products.

Colour is a key aesthetic and compliance parameter, continuous monitoring prevents visible discolouration events reaching consumers.
SPS-ORP Water Quality Sensor
ORP
SPS-ORP Sensor

Oxidation-reduction potential monitoring for disinfection effectiveness, redox conditions, and process control in treatment and distribution.

ORP is a direct measure of disinfection power, falling ORP values indicate that treatment residual is being depleted.

Discolouration is the complaint customers actually see.

Colour is both an aesthetic and a compliance parameter, and it is the one most visible to the public. A discolouration event, driven by iron and manganese release, natural organic matter, or treatment by-products, generates complaints quickly and erodes confidence even when the water is safe. The change often builds gradually before it becomes obvious.

AQUAIOT monitors apparent and true colour continuously with the SPS-Color-C sensor, streaming live readings to the cloud. Rising colour is flagged by threshold alert while it is still subtle, giving operators time to adjust treatment, flush a zone or investigate a source before discoloured water reaches consumers and the call centre.

  • Continuous apparent and true colour measurement
  • Early detection of iron, manganese and organic colour
  • Prevents visible discolouration events reaching consumers
  • Supports aesthetic compliance and complaint reduction

Colour monitoring questions

What causes water to change colour?
Common causes include iron and manganese release from pipework, natural organic matter in source water, and treatment by-products. Colour is a key aesthetic and compliance parameter because discolouration is highly visible to consumers.
What is the difference between apparent and true colour?
Apparent colour includes the effect of suspended particles, while true colour is measured after those particles are accounted for, reflecting dissolved substances. AQUAIOT can monitor both to distinguish particulate from dissolved causes.
How does monitoring prevent complaints?
Continuous monitoring flags rising colour while it is still subtle, before water becomes visibly discoloured at the tap. That gives operators time to adjust treatment or flush a zone, heading off the complaints a visible event would generate.
Can colour monitoring run alongside turbidity?
Yes. Colour and turbidity together separate dissolved colour from particulate cloudiness, which makes diagnosing the cause of an aesthetic event much faster.
