- "...desalinising the sea water and storing it into tanks big enough to supply the whole city."
- ―Dr. Peter Grodin
The desalination tanks are large tanks on Atlantis capable of storing and desalinating sea water to provide fresh drinking water to the city's inhabitants. (SGA: "Hide and Seek")
These tanks would be connected to the city's plumbing and to the showers and baths in Atlantis. (SGA: "Quarantine", "Broken Ties")
