Nick Sloane, a marine salvage expert South Africa born, a director at the US marine salvage firm Resolve Marine, says towing an iceberg 100 million ton from Antarctica could solve the problem. The ideal iceberg would need to be one kilometer in length, 500 meters across and 250 meters deep with a flat surface. If successfully towed, melted water from the iceberg can potentially provide 150 million liters of freshwater every day for a year. To prevent premature melting while being towed, the iceberg will be wrapped in a textile insulation skirt while being dragged across the 2,000 kilometer distance over a three-month period.
Towing the iceberg alone could cost up to $100 million. Sloane says his team will undertake all the risk if the move is approved by Cape Town. “We’ve got private investors standing by on the wings to fund it,” he told the media. Sloane and his partners will only charge a delivery fee if the operation is successful. Cape Town council will decide in August about the project. Cape Town suffered a severe drought earlier this year, leaving the capital city only weeks away from running out of water. South Africa has declared a national disaster over the drought that hit its southern and western regions this year.
