City ahead of schedule on sinking sewer pipe | News
WAIKIKI (HawaiiNewsNow)- A diver from Sea Engineering scraped away barnacles, then workers from Hawaiian Dredging wound a stainless steel collar around the section of plastic pipe floating on the surface of the Ala Wai Canal. The tasks kept the city ahead of schedule.
"I'm very pleased with both the city staff and our contractor Hawaiian Dredging," City Design and Construction Department director Lori Kahikina said.
The 100-foot section surfaced eleven days ago, after air bubbles mixed with sewage gas in the temporary bypass line. The prep work Tuesday was a set up for Thursday. "We're going to do the live tap," Kahikina said "We're going to punch into the 48-inch pipe and close off the corporation stop, which is just a valve, and attach a bleeder hose, and open the two valves to the pipe."
The air and gas that comes out will pass into large carbon canisters that will filter out any odor.
Waikiki resident Philip Blackman said he expected more of a problem. "I was waiting for the bigger zipper effect, when not just one section would come out but you'd end up each day seeing more and more of it pop to the surface," he said.
Kahikina said the pipe is very durable and strong. She said there is little risk of leaking any sewage into the Ala Wai. "Our plan is by Friday to sink that pipe. But again, they're a little bit ahead of schedule, so it may be Thursday," she said. No word yet on how much the work will cost.
