Satellite-Based Leakage Detection and AOI (Area of Interest) Management

Satellite Scanning Requirements

- Scan areas of the UU region for leakage detection on:

- Drinking water assets

- Raw water

- Sewage

- Scanning frequency: daily, weekly, or full region biannually

- Imagery delivery within 4 weeks

- Pre- and post-freeze imagery capability

- SLA failure rebate for delayed scans

- Dynamic pricing based on scan age

- Clear availability of satellite scan schedules to support planning and reactive needs

AOI Identification & Management

- AOIs identified within 100m of UU assets

- AOIs classified by leak status:

- Quiet

- Suspected

- Active leak

- Repaired

- Awaiting repair

- Unverifiable

- AOI journey fully integrated from scan to resolution

- AOI audit trail (e.g., AOIs with no leak detected)

- Oldest leaks alert system

- Ability to interpret AOIs within defined boundaries and estimate leakage return

- Ability to label individual leaks with root cause failure types

Mobile App Features

- AOI investigation and reporting

- Status updates sync with dashboard

- AOI search by reference (field/admin)

- Capture investigation method (e.g., FIDO)

- Offline reporting capability

- Send outcomes to manager for review

- Performance tracking

Dashboard Requirements

- Desktop and mobile compatibility

- Data layers:

- Active and past AOIs

- Asset types (hydrants, mains, private services)

- Regional and county-level performance views

- Leak investigation performance metrics:

- Leaks found

- AOIs investigated

- Daily/weekly outcomes

- Leak insights:

- Leaks per km

- Time to resolve

- Full suite of reporting tools

- Integration with WaterNet / INS / Campaign Management

Integration & Governance

- Ingest UU asset records

- API interface for data exchange

- Link AOIs to INS jobs

- GIS integration (ArcGIS)

- Satellite governance structure needed

- Licence usage tracking

- Training on data interpretation (unlimited licences)

Benefits

- ODI benefit calculation using industry-standard methods

- Streamlined leak detection and prioritisation

Risks & Gaps

- GIS maps sent to Satellite vendor missing key details (material, size, DMZ)

- Trunk main investigations lack coordination

- Dashboard and mobile app status sync issues

- Manual daily reporting

- Inconsistent dashboard usage across regions

- No standard process for linking AOIs to INS

- ODI tracking not embedded

Opportunities

- Extract AOIs into ArcGIS

- Develop API for GIS integration

- Split dashboard views by county

- Generate reports from AOIs

- Link AOIs to campaigns

- Introduce AOI audit trail
