The CIBR team has four field sites investigating the ability of mānuka and kānuka dominated ecosystems to filter out contaminants in wastewater:
Lake Waikare - a site with 4 ha of mānuka dominated ecosystems planted, based in the Waikato located on a dairy farm
The Pot - a 10 ha site that had pine forest that has been harvested and replaced with a mānuka and kānuka dominated ecosystem and irrigated with treated municipal wastewater
Lake Wairarapa - two small field trials located on a sheep/beef farm and one dairy farm in collaboration with farm owners, Greater Wellington Regional Council, and Ngati Kahungunu ki Wairarapa
Duvauchelle - a site in Christchurch with 11 native plant species irrigated with treated municipal wastewater
New knowledge obtained from these project on the effects of native plant systems to mitigate emerging organic contaminants and pathogens in treated human wastewater will make a significant contribution to national and international research in the field of land treatment of biowaste.
