Water costs in South Africa are now where electricity prices were 8 years ago. The symptoms we see now are very similar to what was experienced with ESKOM in those years:
Water infrastructure has been neglected and major capital expenditure budgets were redirected to other social infrastructure development.
Urbanisation and the need for water has driven up the demand without increasing the supply capacity
The department of water affairs have lost key engineering skills associated with the management of water resources
In order to catch-up with this backlog in water and technical infrastructure the cost of water would need to increase well in excess of inflation with still no guarantee of sufficient water resources in the next 20 years
