Toilet Twinning is an initiative which invites people to "twin" their own toilet with latrines in poor communities (an analogy with the twin towns and sister cities movement).[1][2][3] This is a way of raising funds to enable people in the poorest nations to have clean water and a proper toilet, and to learn about hygiene. Toilet Twinners receive a certificate, containing a photo of the twinned latrine, its location and GPS coordinates.
Toilet Twinning used to be a partnership between two international charities, Christian Outreach for Relief & Development (Cord) and Tearfund, but now is solely a charity under Tearfund. It was formed in 2010, in response to the global sanitation crisis.
