The outfall extends about 1.5 miles offshore to a diffuser located roughly 150 feet below the ocean surface, where it is mixed with surrounding waters.<\/p>\n<p class=\"text | article-text\">According to the Navy, similar past incidents involving UV-treated wastewater have shown bacteria levels remained below permitted limits, with no additional environmental impact.<\/p>\n<p class=\"text | article-text\">The treatment plant uses an enhanced secondary treatment system with four steps: clarifiers, activated sludge, sand filtration and UV disinfection. During this bypass, the wastewater skipped the sand filtration step but still underwent UV disinfection before discharge.<\/p>\n<p class=\"text | article-text\">The Navy has notified the State Department of Health as required by the WWTP\u2019s operating permit.<\/p>\n<p class=\"copyright |\">Copyright 2026 Hawaii News Now.
