There has been a migration of millions of people into the Western Cape over the last 20 years from within and also from outside our country borders . The existing infrastructure which is over 30 years old was never going to be sufficient to accommodate for that rapid increase in population growth. The National Government  Department of Water Affairs should have addressed the situation 10/15 years ago. 
The whole of the Republics civil infrastructure with regards to water management is much to be desired. No foresight , no maintenance,no future planning, no common sense and now ............... no water.
