How this category is defined
What counts as water, sewer & drainage: Water main breaks and leaks, sewer backups, storm drain clogs, catch basin concerns, and flooding.
In Toronto’s raw 311 data, the following 3 service_type values are counted as water, sewer & drainage:
- Catch Basin - Blocked / Flooding
- Sewer Service Line-Blocked
- Watermain-Possible Break
To reproduce these counts against the raw feed
SELECT count(*)
FROM <toronto_311_raw>
WHERE service_type IN (
'Catch Basin - Blocked / Flooding',
'Sewer Service Line-Blocked',
'Watermain-Possible Break'
)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.
