In 2005, total water withdrawal was an estimated 13.210 km3, of which 4.520 km3 (34 percent) for agriculture, 3.902 km3 (30 percent) for municipalities and 4.788 km3 (36 percent) for industries (Table 3 and Figure 1).
Surface water is readily available throughout the year and is abstracted mainly for irrigation and domestic uses. The groundwater potential is limited to some pockets of the coastal region and is generally exploited by rural people to supplement their piped water supply. In 1995, surface water represented approximately 97 percent of the total water withdrawal, while groundwater represented 3 percent (Figure 2). About 60-65 percent of groundwater used is for municipal purposes, 5 percent for irrigation and 30-35 percent for industry.
In 1995, about one third of the water withdrawal of the municipal and industrial sectors is lost in the distribution system owing to several factors such as pipe leakage, under-metering, and other unaccounted water losses. Water supply is undertaken by government agencies and privatized water companies.
