Water Efficiency Technology (W.E.T) Program Multi-Residential Funding Application

Please complete this application for projects in multi-residential buildings with 3 stories or more, and wish to determine your eligibility for funding or cost-sharing with the Region of Waterloo.  Money is available for property managers who upgrade all of their building’s showerheads, toilets and tap aerators. 

This program is best suited for medium to high rise apartment buildings interested in long-term savings. 

The Region will review water billing data prior to the launch of the project and compare it to the water billing data for the year following project completion to determine the volume of water saved by the project.

  • Funding is based on project's invoiced costs, water savings achieved and the time for the project to pay for itself
  • Funding available is $0.40 per litre saved per day or less if the upgrades pay for themselves in under two years
  • Project managers often receive a rebate of 5 to 13 per cent of the project cost with water savings often providing long-term financial benefits.
