Sewage spill closes beaches at Honolulu.

A number of beaches have been closed and a body boarding competition cancelled after a sewage spill entered the sea via a storm drain at Ala Wai Boat Harbor. The spill occurred after a blockage in the sewage system close to the University of Hawaii at Manoa, early in the morning of Friday 5 August 2016, which released about 50 000 litres of sewage, some of which then entered a storm drain (designed to carry rainwater) at the intersection of Metcalf and Hunnewell streets.

As well as the obvious dangers to health presented by sewage, which is likely to contain a variety of Bacteria and other micro-organisms harmful to Human health, sewage provides a source of nutrients which can lead to eutrophication and the rapid growth of blooms of Algae, Bacteria or other micro-organisms, which absorb oxygen from the water leading Fish and other aquatic organisms to asphyxiate.
