Mark Zuckerberg adds 110 acres to controversial 1,500-acre Hawaii estate

The $17m purchase for the Facebook founder includes the Ka Loko reservoir, considered high-risk and in need of repairs

Mark Zuckerberg has added 110 acres to his controversial 1,500-acre estate in Kauai, Hawaii, dropping $17m for the purchase.

The 110 acres of land that the Facebook founder and his wife recently bought includes the Ka Loko reservoir, a century-old reservoir whose dam broke in 2006 and released 400m gallons of water that killed seven people on Kauai's north shore.
