NO BREAK FOUND IN NIU SEWER MAIN
City Department of Environmental Services crews unearthed a suspect sewer main overnight and found the pipe intact. No rupture was found, as had been feared.
The trench that crews dug to get to the pipe will be temporarily covered with a steel plate. Lane closures on Kalanianaole Highway will not be necessary during the morning rush hour.
The 16-inch cast iron pipe ruptured three times last month, spilling untreated sewage each time. In each case, corrosion cracks were found and sections of the 45-year-old pipe were replaced.
Yesterday, freshly laid asphalt at the spot of the most recent break began buckling and moisture appeared from underground. That led City Collection Maintenance System Division officials to suspect that the pipe had ruptured again.
“All the evidence pointed to that,” said James Baginski, acting assistance chief of the Collection Maintenance System Division.
Repair crews were called in after pau hana traffic subsided. They worked through the evening and found the pipe to be undamaged.
The City Department of Environmental Services is proceeding with plans to install an emergency hypass line and a permanent underground replacement for the main, which carries untreated wastewater from the Niu Wastewater Pumping Station toward town.
