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
