Port Augusta's Substance Misuse Service is celebrating its 20th anniversary.
The amalgamation of the Sobering Up Unit with the Mobile Assistance Patrol occurred in 1999.
Prior to this, the Port Augusta City Council operated the Mobile Assistance Patrol and the Port Augusta Hospital operated the Sobering Up Unit.
The service, funded by the state and federal government, aims to enhance the health and wellbeing of the community by increasing awareness and knowledge of issues, concerns and effects of substance misuse.
Port Augusta City Council acting CEO Melissa Kretschmer said this has been achieved through many initiatives including the addition of two programs being the Exceptional Needs Program in 2012, and the Assertive Outreach Program in 2013.
"Over the past 20 years, the amalgamation of the Substance Misuse Services has been successful in providing better outcomes for our community, offering more holistic support, assistance and case management for some of the most vulnerable members of our community," Ms Kretschmer said.
"The relationships between the staff and clients have been critical to the success of the service, and this year four of those staff celebrate 20 years of service.
"The Port Augusta City Council and the team at the Substance Misuse Service would like to thank the Port Augusta community and other service providers for their support and assistance over the last 20 years."
