It's believed the girls, aged 10 and 12, became trapped in the Honeypot Rd drain, on the border of Hackham West and Noarlunga Downs, after walking around drains in the area sometime before 7.30pm.
It's believed they used a mobile phone to update their status.
Metropolitan Fire Service Crews used a ladder to assist the girls in climbing to safety.
Ambulance crews were on the scene but the girls were not injured and did not require treatment.
Walking through drains is known as "urban exploring" or "urban caving", and has a popular sub-culture in many major cities, including Adelaide.
One group is known as "Cave Clan".
However, flash flooding is a danger for drain dwellers – last year a man, 25, and a woman, 21, drowned after the Sydney drain they were spraying with graffiti flooded last year.
A third person survived by squeezing through bars and washing out to sea.
