Read the transcript
Most sewage and effluent plants in India still run on log sheets and phone calls. Problems are found late: after the pump trips, after the tank goes septic, after the sample fails.
And when the pollution control board asks for data, someone has to dig through registers.
AquaVigil, from Navbharat Water, changes that. It watches your plant around the clock, and tells you when something drifts.
Sensors measure flow, level, DO, pH, BOD, COD and TSS, and the run and trip status of every pump and blower. A gateway in your panel sends readings to the cloud, where every reading is stored and checked against your limits.
The sensors are standard industrial instruments, so your team can service them like any other.
And the gateway uses open standards, MQTT and SQL, so your data is never locked in.
On the dashboard, you see the plant live, on any phone or computer. Inflow, aeration, outlet quality. Each tile turns red the moment a limit is crossed.
The trends show the whole day: flow in and out, and how aeration responds to the morning peak.
Every pump and blower is tracked: when it ran, and when it tripped. Here, pump one tripped at eleven, and the standby took over.
If you run several plants, the fleet view puts all of them on one screen, side by side.
Every limit breach is logged automatically, with the time and the value. A clean record for your own team, your consultant, and the inspector.
AquaVigil works on new plants built by Navbharat, and on existing plants built by anyone.
For an existing plant, we first survey your panel, PLC and instruments, and then quote only what is missing.
There are three plans. Watch, for live monitoring and alerts. Comply, which adds outlet monitoring parameters, a five-year archive and an audit log. And Operate, where a Navbharat engineer reviews your plant every day.

Live demo
Can I see AquaVigil running on a plant?
Yes. Three demo STPs stream below right now, with faults injected daily.
Watch a pump trip at 11:00 IST on STP-B, a gateway drop at 13:00 on STP-C, a BOD breach at 16:00. Each one raises the alert you would receive on your phone.
What we watch
What does AquaVigil monitor?
Four groups of readings, sent every minute: flow, outlet quality, process health and equipment energy.
Flow in / out
Inlet and treated-water flow, daily totals, recycle ratio.
Outlet quality
pH, TSS / turbidity, BOD-COD surrogate, residual chlorine at the final outlet.
Process health
Dissolved oxygen, tank levels, blower and MBR pressure, dosing pump status.
Equipment & energy
Pump and blower run hours, trips, dry run, kWh per KL treated.
What does AquaVigil alert me about?
Six kinds of fault, on WhatsApp first:
- •Plant or gateway offline
- •Outlet pH or TSS outside consent limits
- •DO low in aeration tank
- •Pump trip, dry run, overflow
- •Energy spike against baseline
- •Sensor stuck or drifting
WhatsApp first, then email, then a phone call if nobody acknowledges. Escalation list is yours to set.
Does it give me a compliance report?
Yes. The Comply tier produces a monthly compliance report PDF and keeps a 5-year archive.
Regulators pick inspections from exceedance alerts, missing data and offline periods. AquaVigil keeps a tamper-evident log of every reading, every alert and every acknowledgement, and turns it into a monthly report in the format your consent order asks for.

How it works
How is AquaVigil installed?
Usually in one day on site, with no plant shutdown.
Gateway in your panel
4G gateway reads the PLC over Modbus or instruments over 4–20 mA. Installed in a day, plant keeps running.
Secure stream
Readings every minute to our India-hosted platform. Buffered on site when the link drops.
Dashboard, alerts, reports
Web and phone. Your operators, your consultant and NBW engineers see the same screen. Open standards (MQTT, SQL export), no lock-in: leave and take your data.
Two ways to get it
Built into every new Navbharat plant
Every STP, ETP or WTP we design and build ships with AquaVigil wired in from day one. It is how we run our BOOT and O&M contracts: the same screen our engineers watch is the one you get.
Retrofit on a plant someone else built
Working plant, no visibility? We fit the gateway to your existing panel and instruments, one day on site, and you pay a flat monthly or annual subscription per plant. No change to your O&M vendor.

Questions we get
Is AquaVigil really free for 3 months?+
Yes. The Watch tier (up to 6 parameters, live dashboard, WhatsApp + email alerts, daily summary) is free for the first 3 months. Gateway and sensors are quoted after a free site survey.
What happens after the free period?+
You choose: continue on Watch (₹4,999), Comply (₹9,999) or Operate (₹24,999) per plant per month, or stop. No lock-in.
Can I see all my sites on one dashboard?+
Yes. Multi-site owners such as FM companies, hotel chains and builders get one dashboard across all their sites.
Will it work with my existing plant?+
Yes. The gateway reads your PLC or panel over Modbus, or wires to 4–20 mA instruments directly. No plant shutdown, usually one day on site.
What if the internet drops?+
The gateway buffers readings locally and back-fills when the link returns. You get an offline alert, the same signal a regulator looks for.
Who owns the data?+
You do. Hosted in India, exportable any time, deleted on request when you leave.
Is this OCEMS?+
AquaVigil runs beside OCEMS, not instead of it. It covers operational parameters the regulator does not see, and keeps the compliance record you need when the inspection comes.
Which instruments do I need?+
Most plants already have flow and pH. We add DO, level and energy where missing; the survey lists exactly what, with prices.
Run on our own plants first. The same stack monitors Navbharat Water O&M sites before any customer sees it.
