The supply of fresh water to towns marked a degree of sophistication but also progress since acquiring fresh water is an arduous daily task. For the most part water was brought in from fresh water sources such as rivers, and channelled underground in conduits, although a small number of aqueducts are known in Britain.

The water was used for drinking, domestic use and for bath houses. In association with the water supply was the necessity to drain the continually running excess water away, hence there being frequent drains throughout Roman towns.
