Dougga has two networks of cisterns, in the north and in the west, one of which is particularly well preserved.
An aqueduct leading to the city, located a short distance from the well-preserved cisterns, is amongst the best preserved examples of this type of structure on the territory of modern-day Tunisia.

The six cisterns of Aïn El Hammam, situated close to the Temple of Juno Caelestis, have a total capacity of 6000 m³ but are in ruins.
They were fed by a spring 12 km (7.5 mi) away and an aqueduct constructed during the reign of Commodus and restored in the last quarter of the 4th century CE.

This site is still used once annually for a festival celebrating Mokhola, who was a female saint and benefactor of Moroccan origin according to local oral tradition The veneration of Mokhola is accompanied with animal sacrifices.
It has been shown that this tradition has pagan origins; the object of veneration was originally the spring, known as fons moccolitanus
The second network of cisterns, the cisterns of Aïn Mizeb, is very well preserved.
Located close to the Temple of Minerva, these eight domed reservoirs can hold 9,000 m³ (320,000 cu ft) and feature a basin into which they decant.
The cisterns are fed by a spring located 200 m (660 ft) away connected via an underground aqueduct.

A final network of secondary cisterns is located in the vicinity of the Aïn Doura Bath, in the south-west of the site.
