Four different source types
Tube wells, rainwater harvesting tanks, community schemes and piped supply each generate their own records.

From rooftop rain to a verified coastal water-supply record.
For DPHE's Water Supply Project in Coastal Areas through Rain Water Harvesting System, Tiger Park is building Brishtir Pani — a Tiger One and Sky Hawk-based web portal and Android app that brings tube wells, rainwater harvesting tanks, community schemes and piped water supply into one monitored, geotagged record.

The assignment
Coastal Bangladesh needed a water-supply option paper reporting couldn't keep up with.
Safe drinking water remains scarce across Bangladesh's coastal zone, where existing options are often inadequate or costly to sustain. Rainwater harvesting has proven suitable and economically viable, with growing acceptance among coastal households. DPHE's Water Supply Project in Coastal Areas through Rain Water Harvesting System needed a way to monitor delivery across many source types and locations — beyond what periodic paper reporting could track.
DPHE project ownership · Tiger Park ICT deliveryDPHE owns the coastal rainwater harvesting programme. Tiger Park built and supports Brishtir Pani.
The Department of Public Health Engineering's Project Director for the Coastal Water Supply Project through Rain Water Harvesting System owns the programme. Tiger Park Limited was awarded the contract through open tender to build and support Brishtir Pani, the system's web portal and Android app.
Challenge
Bring four different water-source types into one monitored record.
Field verification
Installation, water-quality testing and handover needed geotagged evidence, not paper reports.
Financial and procurement tracking
Tender IDs, work orders, NOAs, contractors and payments needed to sit alongside the technical record.
Solution
Brishtir Pani: a Tiger One and Sky Hawk-based system for every coastal water source.
The system combines a role-based web portal and Android app with a filterable dashboard, so field evidence from tube wells, tanks, schemes and pipelines reaches DPHE without waiting for the next paper report.
Offline-capable field capture
The Android app geotags and photographs every source on site, storing submissions locally until a connection returns.
Every source type, one record
Tube wells, rainwater harvesting tanks, community schemes and piped supply each get their own structured record.
Water-quality tracking
Laboratory test results, including fecal coliform, are linked to each community water-supply scheme.
Interactive dashboard
Filterable by location, component, progress status and contractor, down to union level.
Financial and package tracking
Tender ID, work order, NOA, contract amount, invoices and payments sit alongside the delivery record.
Maker-checker validation
Data entered by field staff is reviewed and approved by senior staff before it becomes part of the record.

Representative management view
See delivery status and the field evidence behind it.
Brishtir Pani is designed to connect programme status with source-level evidence. A management view can place physical and financial progress beside Sky Hawk photographs, water-quality follow-up, geographic filters and maker-checker approval—without separating the chart from the record that supports it.

Proven foundation
Awarded through open tender, built on a proven platform.
Tiger Park's proposal was evaluated and awarded under DPHE's public tender (Package SD-CRWH-01).
Brishtir Pani runs on the same Tiger One and Sky Hawk foundation already delivering CEIP-1 and DPHE's earlier water-supply monitoring.
The contract includes a year of paid operation and maintenance support after development, with source code and documentation handed to DPHE.
Built to extend
Designed as a generic platform, not a single-purpose tool.
The terms of reference called for user management, roles and permissions to be built in a generic style — so the same foundation can carry future DPHE water-supply programmes, not just this one.
Generic-by-design modules
User management, roles and permissions were built in a generic style, not specific to rainwater harvesting alone.
A shared Tiger One and Sky Hawk foundation
The same platform already supports CEIP-1, PEDP4 and DPHE's earlier water-supply monitoring systems.
Evidence and framing
Grounded in DPHE's public procurement record.
This case study is built from the signed work order, contract agreement and terms of reference for Tiger Park's tender award. No confidential contract value or internal system screens are reproduced here.
