Marine salvage experts are floating a plan to tug icebergs from Antarctica to South Africa’s drought-hit Cape Town to help solve the region’s worst water shortage in a century.

Salvage master Nick Sloane said he was looking for government and private investors for a scheme to guide huge chunks of ice across the ocean, chop them into a slurry and melt them down into millions of liters of drinking water.

“We want to show that if there is no other source to solve the water crisis, we have another idea no one else has thought of yet,” said Sloane, who led the refloating of the capsized Italian passenger liner Costa Concordia in 2014.

South Africa has declared a national disaster over the drought, which hit its southern and western regions after 2015 and 2016 turned into two of the driest years on record.

Cape Town authorities had warned that taps could run dry altogether as soon as next year if winter rains do not come to the rescue of the port city’s 4 million residents.

Cape Town-based Sloane said his team could wrap passing icebergs in fabric skirts to protect them and reduce evaporation. Large tankers could then guide the blocks into the Benguela Current that flows along the west coast of Southern Africa.

A milling machine would then cut into the ice, producing a slurry and forming a saucer structure that will speed up the natural process, he said.

A single iceberg “could produce about 150 million liters per day for about a year,” about 30 percent of the city’s needs, said Sloane, a director at the U.S. marine-salvage firm Resolve Marine Group Inc.

He said he was planning to hold a conference later this month to try and sell the $130 million project to city officials and investors. The city council was not immediately available for comment.

Meanwhile, dam storage supplying water to Cape Town climbed in the past week for the first time since at least October 2017, according to data provided by the city.

Total storage rose to 20.9 percent, from 20 percent the week before, the city said in a statement published on its website. Usage remained stable at 505 million liters (133 million gallons) a day, the city said, while large parts of the catchment areas for the dams received rain last week.

Dam levels have dropped from close to 40 percent in October as the worst drought on record depleted reserves. Residents of Cape Town are being restricted to using 50 liters of water each a day and told to take 90-second showers. Because usage declined, the city decided that a “Day Zero” would not happen for this year, where the government would be forced to shut off the taps.
