Farming company Mahi Pono has reached an agreement with Alexander & Baldwin to take over full ownership and operations of East Maui Irrigation, the extensive system of ditches and tunnels that diverted water from East Maui streams to sugar plantations for nearly 150 years. On June 17, the companies struck a deal to transfer A&B’s 50% ownership to Mahi Pono and forego the $2.7 million Mahi Pono was originally set to pay for the remaining half of the system.
