CGWA Groundwater Compliance
Piezometers, digital water level recorders and telemetry built to CGWA guidelines.
Groundwater abstraction in India is regulated. An industrial user drawing from a borewell generally needs Central Ground Water Authority approval, and that approval carries monitoring obligations that do not go away once the certificate is issued.
Two measurements are involved. How much water is being drawn — a flow meter on the abstraction line. And what that abstraction is doing to the aquifer — a piezometer or digital water level recorder in the observation well.
Accumax builds both to CGWA guidelines, with telemetry so the data reaches the authority without anyone visiting the site, a dashboard for the analytical parameters the guidelines call for, and alerting when a parameter is exceeded.
A note on wording: we say these instruments are built to CGWA guidelines. We do not claim certification we cannot evidence. If your approval requires a specific certificate, ask us and we will tell you plainly what we hold.
Frequently asked questions
What monitoring equipment does CGWA approval require?
A No Objection Certificate for groundwater abstraction generally requires that abstraction is metered and that water level is recorded, with data made available to the authority. In practice that means a flow meter on the abstraction line and a piezometer or digital water level recorder in the observation well, usually with telemetry so data reaches the authority without a site visit.
Does the data have to be transmitted automatically?
Current guidance expects data to be available to the authority without manual collection, which is why Accumax supplies these instruments with telemetry and a cloud dashboard rather than as local-display-only devices.
What is a piezometer used for in groundwater monitoring?
A piezometer measures the water level in a borewell or observation well. Recording that level over time shows whether abstraction is drawing the aquifer down, which is the question groundwater regulation exists to answer.
