SA sewage standards poor - report
Johannesburg - Only seven percent of South Africa's waste-water treatment systems comply with international standards, reported Business Day on Wednesday.
According to the Green Drop report, compiled by the water affairs ministry, only 45% of waste-water systems assessed scored more than 50%.
Half of municipalities did not take part in the report, which was compiled from 2008 to last year.
Business Day said the report was meant to be released in November but had been kept under wraps.
It was expected to be made public on Wednesday.
