The first efforts to provide a water supply system for Gibraltar are traced to the Moorish occupation. Several wells have been identified as having been constructed in that period. Particularly there was an artificial well/reservoir, now known as Nuns Well, which comprised an underground arched chamber into which ground water was allowed to drain for eventual use.The Moors also constructed an aqueduct, which led water from wells in the Moorish Baths at Line Wall. It is also interesting to note that the Tower of Homage at the Moorish Castle incorporated a shaft like reservoir into which rainwater from the roof was channelled for storage and use.
