  • Sample scenario on urban drainage capacity.
  • Rain intensity, not total rainfall, is the stress point.
  • Ward-level maintenance data is uneven.

The story

Sample climate reporting created for this prototype.

Drainage networks sized for gradual seasonal rain struggle when the same volume arrives in a few hours. In the demo scenario, the failure points cluster in low-lying wards with the oldest storm-water assets.

Key numbers

112 mm

Sample wards flagged

What we know

  • Failures cluster in low-lying wards in the sample data.
  • Maintenance records are inconsistent.

The Scope

What happened · Why it matters · What's next

What happened

A sample review of ward-level flooding shows repeated failures in areas with the oldest drainage assets.

Why it matters

Adaptation budgets are finite; knowing where failure concentrates decides who is protected first.

What we know

  • Failures cluster in low-lying wards in the sample data.
  • Maintenance records are inconsistent.

What's disputed

  • Whether capacity or maintenance is the larger factor.

What's next

  1. 01Municipal budget allocations.
  2. 02Pre-monsoon audit publication.
