The study also showed that a combination of dam actions and non-dam actions such as ground are required to meet the water demands of Greater Beirut and Mount Lebanon from a long-term perspective. The non-dam actions include improved groundwater management, desalination, demand management, and reuse of treated wastewater. The construction of the Bisri dam is therefore one of a number of coordinated efforts made to ensure water security in these areas at least until 2035.
