The Department of Water Affairs in Pretoria has estimated that total water demand in the Vaal river supply area will increase by three percent annually, from 2848 million m 3 in 1989 to 8370 million m 3 in 2025. This will support the deficits in demand until 2002. This will meet the demand deficits until 2007. This will meet demands until 2019. Finally, the Ntoahae dam is supposed to satisfy the new demand deficits in the year 2020 when the entire Lesotho Highlands Water Project is completed.
