Working with the Region of Waterloo, Canada and The Alliance for Water Efficiency, Radian Technical Marketing integrated the Home Water Works calculator with a Waterloo-specific Wet Challenge program, allowing the Region to reduce water consumption both indoors and out. By registering for the Wet Challenge, users actual water use is tracked via a billing data plugin and an API with Campaign Monitor for email communications and messaging. A customer reporting tool allows administrators to search for users based on specified usage fields, postal codes and date ranges.

Region of Waterloo is based in Ontario, Canada.
