Water-shedding: Feel it, it is (almost) here

If you think load-shedding is bad, brace yourself for water-shedding... coming to a tap near you. South Africa is fast running out of water, with the worst drought since 1992 leaving dams at critical levels and diminishing rivers and streams. By NIKI MOORE.
The reason for any potential water shedding is almost a mirror image of why we have load-shedding. Since 1994, millions of people have been added to the water grid with very little thought being given to increasing the capacity of water storage or water intake plants. Combined with mismanagement of water, non-payment for water, huge water wastage through lack of maintenance and neglect, and poor governance through corruption, we are facing a high noon of water shortages that might start affecting us in as soon as a few months.
Smaller municipalities are going to be hit first, and hardest. The Kannaland Municipality (Caltizdorp) has a month of water left. Parts of KZN – northern Ethekwini, the South Coast, the rural north – are facing water restrictions as dams dry up. Much of South Africa is about to be declared an official drought zone. Even where water utilities have access to adequate water supplies – such as the Lesotho Highlands Water Scheme and the Midmar Dam – the strain will be immense. Water will have to be pumped from large dams to smaller dams; pollution will increase in rivers and dams as the water level decreases, water tables will drop as people pump more from boreholes.
While the current crisis can be blamed on the severe drought, there is a large element of bad governance as well. Twenty years of municipal mismanagement has come home to roost, meaning that between 50% and 70% of our fresh water is being wasted through burst pipes, malfunctioning pumps, broken taps and reckless water use (the 'acceptable' global figure for non-revenue water is 30%). Adding to our water woes is an historical accumulation of bad waste-water treatment: fully half of our waste-treatment plants are operating below average standards and fully a third are critical. Fresh water is needed to flush out the pollution of raw sewage oozing into our dams and rivers, and a drought will concentrate effluent to dangerous levels.
