Fig 2 — Continuous supply was implemented in eight city wards (administrative units of Hubli-Dharwad) selected by the Karnataka Urban Infrastructure Development and Finance Corporation (KUIDFC). We used a genetic matching algorithm to identify eight intermittent supply wards that were comparable to the eight selected continuous supply wards on key characteristics. The numbers in the figure show the ward numbers for the 16 wards that were selected for our study.
