Wastewater monitoring

Anora provides satellite-based monitoring of wastewater treatment system behaviour and discharge patterns.

Many cities and sanitation programmes operate extensive on-site and online monitoring systems, yet still face challenges in developing a consistent, system-wide view of performance across plants and over time. Reported data is often difficult to verify independently or interpret at programme scale.

By observing outcomes remotely and repeatedly, the service adds an independent layer of information that supports oversight, comparison, and prioritisation, while complementing existing monitoring and field-based processes.

Observed

• Visible discharge behaviour where treated water enters rivers, canals, or other receiving waters
• Differences in observable conditions upstream and downstream of treatment facilities
• How observable conditions change when the same locations are viewed repeatedly over time
• Relative differences in observable behaviour between treatment facilities within the same region

Not observed / not claimed

• Exact pollutant concentrations or laboratory-grade water quality values
• Internal treatment processes or operational settings inside a plant
• Legal compliance or non-compliance with discharge regulations
• The specific cause of an observed pattern or change

Interpretation principle

The service supports early insight, prioritisation, and oversight. Observations help indicate where closer attention or follow-up may be useful, but they do not replace on-site monitoring, inspections, or regulatory decisions.

The analytical approach focuses on observing outcomes rather than modelling internal treatment processes.

Satellite imagery is used to capture consistent, repeatable views of wastewater treatment facilities and their receiving waters over time, allowing changes and relative differences to be assessed without relying on reported operations alone.

Analysis emphasises comparison and change detection across time and across locations operating within similar contexts.

The approach is designed to complement, not replace, on-site monitoring and inspection systems.

This service is used as a decision-support layer alongside existing monitoring, reporting, and inspection processes.

Inspection prioritisation

Supporting identification of facilities or locations where closer inspection or follow-up may be useful.

System-level oversight

Providing a consistent view across multiple treatment facilities at city, state, or programme level.

Relative performance comparison

Enabling comparison between facilities operating in similar environmental and regulatory contexts.

Programme tracking

Supporting sanitation and river-cleaning programmes by showing how observable system behaviour evolves over time.

Context for reported data

Adding independent context to reported monitoring data to guide verification and follow-up efforts.

This service produces practical outputs designed for oversight and decision-making.

Maps and spatial layers

Geographic outputs showing treatment facilities, receiving waters, and downstream patterns.

Time-based summaries

Simple summaries showing how observable conditions change at specific locations over time.

Comparative views

Side-by-side views supporting relative comparison between treatment facilities.

Screening indicators

High-level indicators highlighting locations or periods that may warrant attention.

Briefing notes

Concise written summaries for decision-makers and programme teams.

Dashboards

Structured views combining maps, summaries, and indicators for ongoing oversight.

Engagements typically start with a limited, well-defined scope and expand where the service proves useful.

Scoping

Definition of geography, facilities, time period, and decision questions.

Pilot or exploratory use

Time-bound analysis to assess relevance in a specific operational or programme context.

Operational use

Recurring delivery to support ongoing oversight, comparison, or programme tracking.

Review and adjustment

Periodic refinement of scope, outputs, and delivery frequency.

This service is currently offered in an exploratory and pilot-oriented form.

It is used to support system-level insight, screening, and prioritisation alongside existing monitoring and inspection processes.

Typical use today includes scoped analyses, pilots, and early operational deployments adapted to the needs of each engagement.
