Transparent by design.

Service demand is not water quality.

A modeled relative indication of service demand. It does not measure household water quality or drinking-water safety.

A neighborhood score cannot identify a contaminant, diagnose a household water issue or certify water as safe to drink. No modeled values are published until actual source-backed inputs exist.

Current methodology

Version 1.0 · Published 2026-09-06. Methodology changes create new versions and snapshots. Historical scores are preserved.

Normalization and missing values

Component inputs are stored separately on a 0–100 scale. A published score is the weighted mean of available components: sum(value × weight) / sum(available weights). Raw imported values are retained with their transformations; normalized snapshots do not overwrite them.

Renormalize weights across available source-backed normalized components. Publish no score when no components exist. Never impute neighborhood values from provincial statistics.

Privacy comes before a chart

Public trends require at least 20 independent valid requests per cell by default. The hard minimum is 10. Small cells and raw comments are withheld. Exact consumer addresses, coordinates and contact details are never public map layers.

Provider coverage

Coverage counts use the live registry of active, verified participating providers with accepted terms and available capacity. They describe platform participation, not all businesses in an area. Actual routing also checks service fit, caps and lead permissions.

Geography and dates

Consumer areas use approximate curated point locations. Natural Earth land geometry is geographic context, not a neighborhood boundary. Province-level information remains province-level. Every published data point retains source geography, period, retrieval date and methodology.

Review cadence

Editorial guidance is reviewed every 6–12 months. Data snapshots are reviewed monthly or when meaningful new source inputs are available. Utility notices require their own dates and expiry. Corrections can be requested through contact.
