Tunneling completed on Honolulu sewer project

摘要

Tunneling on the Kaneohe-Kailua gravity sewer has been completed. The project is the largest sewer project in Honolulu, HI, and it will convey waste water flows from Kaneohe to Kailua while providing wastewater storage to help prevent overflows and spills, especially during storms. The 5 km (3-mile) route linking the Kaneohe Wastewater Pre-Treatment Facility (KWWPTF) to the Kailua Regional Wastewater Treatment Plant (KWWTP) took 13 months to bore through.
