Water was provided to both the Alhambra and the Generalife by the ''Acequia del Sultan'' (also known as the ''Acequia del Rey'' or ''Acequia Real''),{{efn|The canal was known as the ''Sāqiyat al-Sulṭān'' in Arabic ({{Langx|ar|ساقية السلطان|lit=canal of the sultan}}; {{Langx|es|Acequia del Sultan}}), but after the Nasrid period it became known in Spanish as the ''Acequia del Rey'' ('Canal of the King') or the ''Acequia Real'' ('Royal Canal').<ref name=":9" />}} which still exists in large part today. It draws water from the Darro River at an uphill location in the foothills of the Sierra Nevada, about 6.1 kilometres east of the Alhambra.{{sfn|López|2011|pp=239–257}} A smaller branch known as the ''Acequia del Tercio'' also splits off from it several kilometres upstream and proceeded along higher ground before arriving at the top point of the Generalife's palace and gardens. The main branch, proceeding along lower ground, also arrives at the Generalife palace and supplies water to its famous ''Patio de la Acequia''.{{Sfn|Ruggles|2000|pp=170–174}}{{sfn|López|2011|pp=239–257}} Both canals generally ran along the surface but some parts ran through tunnels cut directly into the [[bedrock]].{{Sfn|Ruggles|2000|pp=170–174}}{{sfn|López|2011|pp=239–257}}

After arriving at the Generalife, the canals turn towards the southeast and run past the gardens. They then join before turning back towards the Alhambra, where the water enters via an arched [[Aqueduct (water supply)|aqueduct]] next to the ''Torre del Agua'' ('Water Tower') at the Alhambra's eastern tip.{{sfn|López|2011|pp=239–257}} From here it is channelled through the citadel via a complex system of conduits (''acequias'') and water tanks (''albercones'') which create the celebrated interplay of light, sound and surface in the palaces.<ref name="Salmerón_III" />
