The removal of the "black noodle" in the Ala Wai canal in Hawaii has begun.

HONOLULU -

In 2006, 48 million gallons of raw sewage spilled into the Ala Wai Canal after heavy rains caused the sewage line to break.

Seven years later, city crews are finally removing the "Black Noodle" -- the temporary pipe that was installed.

"We installed a brand new pipe underground and under the Ala Wai Canal. That pipe is now done, so removal of this temporary pipe is the last phase," said Design & Construction Director Chris Takeshige.
The removal of more than 5,000 feet of pipe along the canal and a state-of-the-art system that has a backup pipe in place comes with a cost of more than $40 million, according to city officials.

"It also allows for development. The changing atmosphere of Honolulu is in a growth stage, I think. Allows for further development in Waikiki. You got Increased capacity redundancy," said Takeshige.

Crews will remove the old pipe system by cutting it into smaller pieces and haul it away.

"As they lower pump in and start pumping the sewage out and into the manhole, the pipe now gets filled with air. What happens is the pipe floats to the surface," said Takeshige.

City officials say the removal will take about a month and a half and, hopefully, be completed by the end of August.
