A great way to reduce your bottled water costs in this hot region is to use free cold water dispensers, locally called sebil (pronounced say-beel), which can usually be found on the sides of the streets and mosque courtyards in less-touristed towns and neighbourhoods in the region. They look like small, white refrigators and usually have two faucets: red one delivers warm (or mildly hot depending on the weather) water, while the blue one offers comfortably cold water. Though the water coming out of the faucets is not from a commercially-bottled jar, and likely from the city water network, it's harmless and causes no stomach upsets. A way to reduce the risk may be allowing yourself a week after arrival in the region to get accustomed to local microflora and -fauna that may be present in the water and then taking full advantage of sebils.
