How this category is extracted

What counts as water, sewer & drainage: Water main breaks and leaks, sewer backups, storm drain clogs, catch basin concerns, and flooding.

In Baltimore’s raw 311 feed, the following 3 service_type values roll into water, sewer & drainage:

  • WW-Sewer Water In Basement
  • WW-Water Leak (Exterior)
  • WW-Water No Water

To reproduce these counts against the raw feed

Analyst tip: Austin uses 'AW -' (Austin Water) and 'WPD -' (Watershed Protection Department) prefixes. Calgary uses 'WATS -' (Water and Sewer). NYC uses 'WATER LEAK' and 'Water System'. Baton Rouge has a broader 'ENVIRONMENTAL ISSUES' that may include non-water items — cross-check against the raw feed if precision matters.
