4. Methods

This indicator is taken from results published in Environment Canada's Municipal Water Use and Pricing (MUD) survey and Municipal Water and Wastewater Survey (MWWS) reports from 1991 to 2009, 2009 to 2011 Household and the Environment Survey (HES) data, and 2011 Survey of Drinking Water Plants (SDWP) data.

The 2006 to 2011 HES data were collected based on the following question:
