Like all Roman cities, Tolosa needed a clean running water supply.  Aqueducts transported water from Ardennes to a reservoir.   According to archeologists and specialists, Tolosa's aqueducts appear to have been paved with marble, allowing for smooth water passage.  The reservoir was located at the highest point in the city.  In Tolosa's case this was in current day Place Esquirol.  

     The water was then channeled down throughout the city.  On average two fountains were present for every insulae.  Water was also channeled to public bathhouses where Romans washed and relaxed.  The remains of a bathhouse were found in Place des Carmes.  This was believed to be a public facility.  Villas had a more direct supply of water and some had private bathing facilities.  

     Sewers systems found were built directly under the cities' roads to transport waste out of the city.  The main sewer found in Tolosa was the Cloaca Maxima, which ran under the main street, the Cardo Maximo.  

     In these respects Tolosa very much fit the sanitation aspects of a typical Roman city.
