Foyle Haven was established in 2001 by a group of committed people from the local community who wanted to provide support to local street drinkers. Demand for its service grew to such a degree that in 2010 it needed to amalgamate with a national charity to ensure sustainability into the future. In 2011 Foyle Haven amalgamated with Depaul Ireland. It is a safe space where street drinkers can access practical assistance and support to reduce the harm caused by their use of alcohol. It also offers a harm reduction floating team which provides support around substance use and tenancy sustainment to people who are unable to attend the day service.
