"Surprisingly Melbourne is not on this list...."
Comment:Melbourne is on the following list :
Many citiesworldwide have invested in large desalination plants to meet or
supplementtheir potable water needs by conversion of abundant seawater into
drinkingwater.Riyadh in SaudiArabia (274 milliongallons/day)Sorek in Israel
(165 million gallons per day)San Diego inCalifornia (50 million gallons per
day)Chennai and Jamnagar in India(each about 26 million gallons per day)
Australia hasdesalination plants in Perth, Sidney ,Wonthaggi-Victoriaabout 137
Km from Melbourne (145 million gallons/day)
At the last count reported by Google there were over 18 thousanddesalination
plants in the world producing over 23 billion gallons of drinkingwater per day
sufficient for about 300 million people. 14KW Hours of energy arerequired to
produce 1000 gallons of desalinated water. Some of the energyrequired could
come from solar conversions.
The desalinationprocess removes the minerals that we take for granted in the
fresh rain water supply.Required minerals can be metered back into the
desalinated drinking water so that the water meets the drinking water standards.
In Goa we are very fortunate to have abundant fresh water. Monsoon and
However as the population increasesdramatically, perhaps a large desalination
plant may be needed to supplement theneeds in the dry season. Best Regards. E.
