With Cape Town's water crisis expected to run well into 2019, conservation experts have been looking to other cities also affected by drought.
The World Wide Fund for Nature in South Africa says we can draw from the experience of places like Sao Paulo in Brazil.
The country went through a major water crisis from 2014 to 2016, with dam levels dropping to 5 per cent.
They had to cut back on water supply to make sure there's water in the city and eventually the rain came and that saved them from running out of water completely.— Christine Colvin, Senior Manager Freshwater Programme at WWF SA
There are still concerns that they have not taken the long term view and I think Cape Town has been good in that respect, we know that under conditions of climate change we are likely to have a drier future, so we are trying to look for long terms solutions and many other cities haven't done that.— Christine Colvin, Senior Manager Freshwater Programme at WWF SA
Colvin has warned against what is called the "Tanker Mafia" which has taken over in Karachi, Pakistan.
This is a system where water is being sold through the black market.
She says while we enable innovation and other alternatives, we need to guard against such practices in South Africa.
