‘Auckland has come up with a novel plan for getting rid of hundreds of thousands of tonnes of human waste – use it to fill one of its many extinct volcanos, then turn it into a regional park.
Local authority-owned Watercare Services announced this week that it had signed a $25 million, 30-year deal with Puketutu Island’s owners to dump the 61 tonnes of biosolids – cleaned, treated and dried human waste – produced by its Mangere treatment plant each week.
The waste would be dumped on a side of the volcanic island that had been extensively quarried in the past 50 years. The island’s original volcanic cone formation could also be rebuilt using the biosolids, subject to public opinion, spokesman Clive Nelson said. [..]
Auckland University vulcanologist Ian Smith said Aucklanders need not be concerned that they would be showered in “biosolids” in the event of an eruption.’
