The tonnage of waste
produced in the CMA per annum is estimated at between 738 183 t/a and 1 million t/a.The lifespan of existing domestic landfill sites range from 2 to 30 years,
which add up to a total of 64 years. The remaining air space of these sites is
approximately 19.6 million m3.
There are six operating general waste landfill sites in the CMA,
two of which have operating permits from DWAF. According to the National Waste Management
Strategy, all landfills sites will be registered, permitted and operated in accordance
with Minimum Requirements by 2005.
The current financial cost of landfilling is between R30

incorrectly disposed of at general waste sites.
There are two landfill sites based on sandy soils, increasing the
risk of groundwater pollution from leachate.
