Since when did maintenance and expansion of infrastructure
only start after fixed levies were added? 
Stop believing that balderdash.
Its not like things were not maintained when water for example was a lot less costly. A cost only inflated by the municipality.
Maintenance and new infrastructure was done in Cape Town - long before anyone dreamt up a new tax...that only paying customers pay for - plus 15% VAT.
Stop believing everything you read and swallowing narratives by City spin doctors.
The price of the first 6Kl of water you consume in Cape Town has gone up by just short of 200% in 6 years.
Let that sink in.
