The Burj Khalifa's water system will supply an average of about 946,000 litres of water per day. At the peak cooling times, the tower will require approximately 10,000 tonnes of cooling per hour, which is equivalent to the capacity provided by 10,000 tonnes (22.4 million lbs or 10.2 million kg) of melting ice in one day^[61].

The building has a condensate collection system, which uses the hot and humid outside air, combined with the cooling requirements of the building and will result in a significant amount of condensation of moisture from the air. The condensed water will be collected and drained into a holding tank located in the basement car park,this water will then be pumped into the site irrigation system for use on the Burj khalifa park^[62].
