In what is being touted as a ‘world first’, the landscape of a volcanic island sacred to mana whenua in the Manukau Harbour is being restored using treated human waste. Kendall Hutt reports.
Four volcanic cones on Puketutu Island that were destroyed decades ago are being rebuilt – with human poo.
The process of using treated sewage sludge (biosolids) to restore the island, known as Te Motu a Hiaroa to mana whenua, is “worldwide unique”.
Watercare, who is in charge of the project, will save millions of dollars by using the biosolids to rebuild the cones instead of trucking it away to northern Waikato.
