Regulate discharge on live data — not on paper returns that arrive months late.

If you're a Department of Water and Sanitation regional office, a Catchment Management Agency, a water board or a metro pollution-control unit, you carry a hard mandate: keep what enters the rivers within limits across dozens of dischargers you don't operate. Today you find out a treatment works is spilling or a factory is over its load weeks later, from a self-reported return or a fish kill. addanode gives a regulator continuous, independent telemetry from every discharge point and key river reach in the catchment — so a breach raises an alert the day it happens, enforcement is built on defensible data, and the public can see the same numbers you do.

The oversight gap

You're accountable for water you can't currently see.

Self-reporting arrives late and sparse

Licensed dischargers report their own grab-samples, often monthly or quarterly, sometimes not at all. By the time a non-compliant result reaches your desk, the pollution has long since moved downstream — and the gaps between samples are exactly where a quiet, persistent breach hides.

Failing works pollute before anyone is told

A wastewater treatment works that loses blowers, pumps or power can discharge raw or partially-treated sewage for days. Without independent monitoring, the first signal is often a community complaint, a downstream abstraction shutdown or a dead river reach — not a number.

Enforcement needs evidence, not anecdotes

A Section 19 directive, a non-compliance notice or a licence review under the National Water Act has to stand up. Intermittent samples are contestable; a continuous, time-stamped, independently-held record is far harder to argue with.

Public trust is built on transparency

Green Drop, Blue Drop and No Drop assessments, and the river-health questions communities ask, all turn on credible data. When the public can see live water quality for themselves, confidence in the regulator follows the numbers.

What a regulator sees

The whole catchment on one dashboard.

Every discharge point, live

Continuous flow and quality telemetry from each licensed discharge — municipal works, mines and industry — time-stamped and independent of the discharger's own reporting.

River & ambient quality

In-river water-quality sensors upstream and downstream of dischargers — pH, dissolved oxygen, conductivity, turbidity, ammonia, nutrients — to read river health and attribute a change to a source.

Exception flags, not noise

The dashboard surfaces the dischargers and reaches that are out of limits or trending the wrong way, so a small team focuses enforcement where it counts.

Pollution early warning

A sudden DO crash, conductivity spike or ammonia surge raises an alert in hours — the early signal of a sewage spill, a chemical release or an upstream works failure, before a fish kill makes it public.

Enforcement-grade records

Defensible, continuous, independently-held logs to support Section 19 directives, non-compliance notices and water-use licence reviews — exportable for legal and audit use.

Public transparency view

An optional open dashboard publishes near-real-time river and discharge quality to the public, complementing Green Drop / Blue Drop and rebuilding trust on visible data.

How we scope a catchment

Start at the points that change a decision.

  • Map the catchment's risk. Rank discharge points and river reaches by load, history and downstream use — drinking-water abstraction, irrigation, sensitive ecosystems — and instrument the high-consequence points first rather than everything at once.
  • Monitor source and receiving water. Pair discharge-point telemetry with upstream/downstream in-river sensing so you can both hold a discharger to its licence and read the river's actual response.
  • Set limits per point. Each discharge point carries its own licence conditions; thresholds and alerts are configured per point and per parameter, so an alert means a real exceedance for that licence.
  • Make it independent and tamper-evident. Sensing and logging the regulator controls — not data the discharger compiles — with time-stamping that holds up in an enforcement process.
  • Reach off-grid points. River gauges, outfalls and rural works far from power and fibre run on solar and low-power radio (LoRaWAN, NB-IoT, 4G), buffering through load shedding so the record stays continuous.
  • One platform. Discharge, river quality and exceptions sit together on the in-house addaNet platform, with exports for reporting and an optional public view.

Independent by design: the value to a regulator is data you hold, not data you're handed. Because addanode builds the hardware and the platform in-house, the monitoring sits under the authority's control end to end — sensor, network and dashboard — rather than depending on each discharger's own instruments and goodwill.

Regulatory references — the National Water Act, water-use licences, Section 19, Green/Blue/No Drop — are for orientation. Confirm current requirements and the use of monitoring data in any enforcement process against the latest DWS guidance and your legal advisers.

Who this serves

Built for the authorities that carry the mandate.

DWS regional offices & CMAs

Oversee water-use licence compliance and catchment health across many dischargers with continuous, independent data instead of self-reported returns.

Metros & district municipalities

Pollution-control and environmental-health units monitoring industrial dischargers, trade-effluent permit holders and their own works. See also trade-effluent monitoring.

Water boards

Protect bulk-supply source water by watching what enters the catchment upstream of your abstraction and treatment.

Provincial environmental departments

Track river health, eutrophication and pollution incidents across a province with a single, attributable evidence base.

Frequently asked

Regulatory oversight questions.

Most oversight projects start with one of two pressures: a catchment in visible decline, or an enforcement case that needs data that holds up. Here's how we approach both.

Self-reporting depends on the discharger's own instruments, sampling honesty and timeliness, and it reaches you as periodic snapshots. Regulatory monitoring is sensing and logging the authority controls — continuous, time-stamped and independent — so you see a breach when it happens rather than when it's reported, and the record is far stronger in an enforcement process.
That's a core use. Continuous, time-stamped, independently-held records are designed to be defensible and exportable for legal and audit use. Confirm how monitoring evidence is applied in any specific enforcement step with your legal advisers and current DWS guidance — the platform's job is to give you a credible, unbroken record to work from.
No. We rank points by risk and downstream consequence and start with the high-impact ones — a failing works above a drinking-water abstraction, the largest industrial load — then extend coverage. You get value from the first points without a catchment-wide rollout.
Yes. An optional open dashboard publishes near-real-time river and discharge quality so communities can see the same numbers you do — which complements Green Drop / Blue Drop transparency and tends to rebuild trust faster than any report.
With solar power and low-power radio — LoRaWAN, NB-IoT or 4G — and edge buffering that holds readings locally and syncs when connectivity returns. So river gauges and rural outfalls report continuously, and load shedding doesn't punch holes in the catchment record. See remote & off-grid water monitoring.
Pairing discharge-point telemetry with upstream/downstream in-river sensing lets you attribute a shift to a reach and, often, to a source — a conductivity step or DO crash that appears below one outfall and not above it. It narrows where to look and what to ask for, rather than proving causation on its own.
