摘要

The City and County of Honolulu (CCH) is constructing a deep wastewater storage and conveyance tunnel on the windward side of Oahu. The approximately 3 mile (4.8 km) long, 10 ft (3 m) diameter tunnel will help bring Honolulu into compliance with a 2010 Consent Decree between CCH, EPA, and local stakeholders. The tunnel, combined with improvements to treatment facilities in Kaneohe and Kailua, replaces an existing pump station and force main system and consolidates flows from over 200 miles (320 km) of collection lines to a single storage and conveyance system. This paper discusses major planning and design considerations for the tunnel, and the role Oahu's sensitive environs played in its selection.
