In Cartagena Street there are baths to which are related: a water deposit and an aqueduct which supplied them with water and a number of drainage channels.
In Cartagena Street, next to the La Molineta cemetery, are supposedly hipocaustum baths corresponding to a thermal installation. These baths were transformed in a second phase to an oven. For the baths water needs a water deposit was built nearby, located between San Juan, San Isidro and Santa Teresa streets, and an aqueduct which supplied them, of which a number of stretches have been studied. The water probably came from a point in the Los Lorentes dry river bed, or was obtained from wells in La Molineta itself. Connected to the drainage of the baths there would be a number of excavated channels in the natural earth, located in various parts of Cartagena Street.
The construction date of the water deposit, and therefore of the whole complex, including the baths, would not have been much later than 360. This date is given due to the appearance among the reused ceramics in the lime mortar of the water deposit fabrication of fragments of African D, corresponding to types which began to be produced at this time. At the same time, the spacing relationship between baths, water deposit and the La Molineta cemetery allow us to think in joint planning of all these elements.
