Verified field measurement
Nextent Labs builds the systems that make those numbers trustworthy — from the officer standing at the well to the assessment on the Ministry’s desk. Validated, auditable, aligned to the national methodology, and deployed inside government infrastructure.
Two questions
no register can
currently answer
Ask of any manual water-level reading in an Indian groundwater register: was it taken where and when it says, and is the value physically plausible for that well? Most systems can answer neither, because they were built to store a number, not to establish it.
This is not a question of honesty. It is a question of instrumentation. A register that cannot distinguish a carefully taken reading from a hurried one gives the careful officer no credit and the analyst no basis for weighting.
Provenance and plausibility
Provenance and plausibility, established at the moment of measurement rather than argued about a year later.
Provenance
Proof of place, time, device and person — bound to the reading itself, not stored in a separate log that can drift away from it.
Plausibility
Statistical screening against the well's own history and its neighbours, so an implausible value is questioned while the officer is still standing there.
Five steps, and the officer only sees one of them
Planning, verification and approval happen on the desktop. In the field, the app asks for five entries and gets out of the way.
01 Plan the season
Pre-plan the data-collection windows for the season, allocate wells to field teams, and assign the officer, assistant, dates, vehicle and device.
02 Capture at the well
The form unlocks only when the device is at the well. Depth to water from the top of casing, reading height, a photograph of the well and its surroundings — and each works with or without signal, so you get what the field actually needs to capture.
03 Screen automatically
Each reading is checked against the well’s own record and against the wells around it. Anything flagged is highlighted for review. Nothing is rejected — a flagged reading is still recorded, because a blocked reading is a lost one.
04 Approve and recheck
Supervising officers approve schedules and readings, order a recheck where the record warrants it, and authorize visits that fall outside the collection window. Every decision is attributable.
05 Publish to the record
Approved readings pass into HydroGeoSenZ and ABMIS as first-class observations, carrying their provenance with them into every analysis and assessment downstream.
The rules GroundWatch is built to
These are design constraints, not aspirations. Each one has captured a feature to be cut.
Flag, don't block
The system questions a reading; it never refuses one. An officer who cannot record what the instrument says will record something else.
The officer's day gets faster
Anything that moves field work slower will be worked around, and a work-around system verges nothing. Next takes arrive pre-filled from the master record.
Verifiable without the vendor
A department must be able to verify that its own records are intact without asking Nextent Labs, and without our presence being available.
Offline first
Connectivity at a monitoring well is the exception. Capture is designed for its absence, not degraded by it.
Zero confusion for senior officers
The approval screen is organised by people with a good day, one to do. They show the decision, the evidence, and nothing more.
Yours to run, and yours to verify
GroundWatch is licensed per deployment per year — never per user, because a per-user price is a tax on collecting more data. It is self-hostable inside departmental infrastructure with no dependency on a Nextent-operated service.
Self-hosted
Run entirely within government-owned infrastructure, so the same asset/source stack is in the rest of the system.
Independent verification
Designed so that the integrity of a record can be checked with a tool the department holds, not one we operate.
Priced per deployment
Add field teams and wells without adding cost. The incentive stays pointed at better coverage.
Parent to what comes next
Builds the platform for further field applications — pumping-test capture, spring monitoring, other field work — on the same mission and the same chain of custody.
Where GroundWatch changes the outcome
01
Seasonal monitoring rounds
Plan, allocate and track field, pre- or post-monsoon rounds across a district, and see completion in real time rather than at the end.
02
Data quality remediation
Identify which parts of a historical record can be relied upon, and re-establish the rest with verified re-measurement.
03
Programme reporting
Give a linked programme evidence that its measurement obligations were met, well by well and visit by visit.
04
Participatory management
Support community and panchayat-level monitoring with the same chain of custody as departmental measurement.
05
Telemetry cross-checking
Compare a manual reading against the telemetry record for the same station and period, and settle which is drifting.
06
Field workforce management
See allocation, visit exceptions and progress for every team, and reallocate when a route or season changes.
Designed for deeper understanding
Tell us which part of your groundwater programme is costing you the most time, and we will show you what the platform does about it — on your own basin geometry.
