    "conversionMethod": "The Lahore District polygon was reduced by the dated 2019 WASA serving-area reconstruction and by official PULSE polygons labelled Cantonment and DHA. Cantonment and DHA are shown as identified independent-system candidates because WASA's public totals expressly exclude those systems. The remaining polygon components are retained as later-WASA-expansion or local-network candidates.",
