Annual Potable Water Consumption at 7.5 bcm

Potable water consumption amounts to a massive 7.5 billion cubic meters per annum, Iran's energy minister said.
"The country's limited non-renewable resources, including water, are being wasted in the worst possible way," Reza Ardakanian was also quoted as saying by IRNA on Thursday. 
According to the minister, wasteful consumption patterns must be replaced by judicious ones, otherwise the water shortage challenge cannot be tackled despite the rise in precipitation rate.
"Close to 4.3 bcm of wastewater are produced in Iran per year, of which 3 bcm are either not treated or poorly-treated, causing an array of health and environmental disasters," Ardakanian said. Bacteria, pathogens and parasites found in untreated sewage can threaten people’s health, causing gastroenteritis, E.coli and salmonella.
