KAILUA, Hawaii –
The tunnel boring machine called “Pohakulani” is expected to complete its 3-mile journey from Kailua to Kaneohe on Tuesday in an underground sewer tunnel. The “Pohakulani” drilled through rock 62 feet under ground.
The machine began its three-mile journey 13 months ago.
The route links the Kailua Regional Wastewater Treatment Plant to the Kaneohe Wastewater Treatment Plant.
