Results obtained indicated that the increase in total supply of water may be attributed to the increase of, desalinated water, treated sewage water, and treated agricultural drainage water. Based on results, the highest water consuming sector is the agricultural sector as compared to municipal and industry sectors. Results indicated that demand for water is positively affected by the harvested area, population size and number of industries; however a negative relationship between demand for water and per capita gross domestic product is detected. Regarding supply of water, results obtained indicated that the supply of water is positively influenced by the production of desalinated water and the storage capacity of dams.
