Providing Water Conservation Assitance to Social/Affordable Housing

We are looking at providing assistance regarding water conservation tools to social/affordable housing in Calgary and would like to hear about any other cities that have already done this. We would like to know what, if any, unique challenges have come up and what sort of assistance was provided (rebates, fixtures, audits, etc).
