Displays the locations of some of the submarine sewer pipelines for the State of Hawaiʻi as recorded on NOAA nautical charts, including Oʻahu as well as one each on Maui (Kīhei) and the Big Island (Kona). Not all submarine pipelines are required to be buried, and those that were originally buried may have become exposed. Mariners should use extreme caution when operating vessels in depths of water comparable to their draft in areas where pipelines may exist and when anchoring, dragging, or trawling.
