Every site, every season
Water table depth and water quality had to be captured consistently at the same monitoring points, dry season and wet season, year after year.

Client case study · DPHE · Aqua Watch
Every groundwater reading, on one governed record.
Aqua Watch runs on Tiger One's dynamic field-survey engine, deployed for DPHE's Survey Investigation and Research Division to track water table levels and water quality — arsenic, iron, manganese and chloride — across seasonal monitoring rounds, year after year.

Project context
Groundwater conditions change by season and by site — the record needs to keep up.
Water tables rise and fall between the dry and wet seasons. Arsenic, iron, manganese and chloride levels vary across the monitoring network. DPHE's Survey Investigation and Research Division needed a way to capture that pattern consistently, year after year, without commissioning a new system for every round.
DPHE Survey Investigation and Research Division · Aqua WatchDPHE owns the monitoring programme and its data; Tiger Park supplies the survey platform it runs on.
Aqua Watch is a Tiger One installation, delivered under a direct contract with DPHE's Survey Investigation and Research Division to enhance the department's water table and water quality data collection system — completed on schedule and accepted at full performance.
The monitoring challenge
Keep every site, every season, on one consistent record.
Multiple substances, one record
Arsenic, iron, manganese and chloride each needed their own validated field, tied to the right site and round — not scattered across spreadsheets.
Draft work needed a gate
Field entries had to be reviewed before they counted as the official record, so a reading in progress couldn't be mistaken for an approved one.
The digital solution
One dynamic survey engine, configured for groundwater monitoring.
Aqua Watch is configured on Tiger One's dynamic field-survey engine and connects with related water-resource information in the wider Tiger One ecosystem. Administrators define the sections and fields a survey round needs; field teams fill them in against a monitoring point; district and administrative reviewers govern what becomes the official record.
Seasonal survey rounds
Each round is scheduled with its own start and end date, so dry-season and wet-season data stay clearly separated, year after year.
Site-level record
Every monitoring point keeps its own history across rounds, with location captured down to division, district, upazila and union.
Structured field capture
Water table level, arsenic, iron, manganese and chloride are captured as defined fields, not scattered across spreadsheets.
Draft-to-approved workflow
A reading only becomes part of the official record once it has been reviewed and approved.
Trend and comparison views
Season-over-season and year-over-year comparisons turn individual readings into a monitoring picture.

Trends and analytics
Individual readings become a pattern administrators can act on.
Tiger One turns Aqua Watch's structured survey rounds into water-table trends, mapped monitoring records and geographic comparisons. Administrators can filter from division to union, compare survey years and examine the history of a selected groundwater point without exposing draft records as final data.

Monitoring value
From scattered readings to one governed water-quality record.
The same structured fields carry forward every season, so this year's readings compare cleanly with last year's.
Arsenic, iron, manganese, chloride and water table sit together against the same monitoring point, not spread across files.
Draft entries stay draft until an approver signs off, so the official record reflects reviewed data.
Aqua Watch belongs to the wider Tiger One ecosystem and can connect its site histories with complementary PICMaC aquifer context.
Future potential
A growing groundwater record for DPHE's R&D division.
Wider monitoring network
Additional monitoring points and parameters can be added to existing survey rounds without a new build.
Cross-programme comparison
Aqua Watch's site-level water-quality record could sit alongside PICMaC's aquifer and river potential data for a fuller water-resource picture.
Early-warning trends
Season-over-season comparison creates the foundation for flagging sites where conditions are shifting.
