Story: Engineering on the sea floor

From sewer outfall to marine reserve, Ōwhiro Bay

From sewer outfall to marine reserve, Ōwhiro Bay

The only indication that there was a sea-floor structure just offshore of this beach at Ōwhiro Bay, Wellington, was the warning sign. Most of New Zealand’s towns and cities are on the coast and pump their sewage through pipes into the ocean. Until the 1990s much of this waste was untreated. The Ōwhiro outfall was closed in 1994. Although it remained as an emergency outfall for some time, this has been closed and Ōwhiro Bay is now part of the Taputeranga Marine Reserve.
