The Vetiver grass will tolerate high levels of nitrates, phosphates, heavy metals, and agricultural chemicals. The Vetiver System can be used for treating wastewater, rehabilitating mine tailings, stabilizing landfills and general rubbish dumps. The Vetiver System takes up the toxic materials and confines the contaminates to the effected area.
More details are available at galleries 1 and 2 and in the TVNI archives (see water and mining). The two handbooks at the bottom of this page provides good technical and field experience data and images.

Watts Bridge (Australia) airfield Vetiver System effluent treatment. This is an update of a previous posting. Additionally we provide a short report from Veticon Consulting on the most recent analysis of effluent treatment. The data indicate that when properly applied the Vetiver System is very effective in the disposal of the effluent discharged from sewage system. The success of this project depends very much on the proper implementation and subsequent management of the site. Learn more .... |

Coral reef protection using VS. Don Miller of New Zealand has been working in Vanuatu (South Pacific island) for some years and demonstrates in this slide show how vetiver hedgerows can be used as an essentail part of reforesting badly eroding landscapes to prevent sediment reaching the sea and destroying coastal coral reefs and fisheries. Don's work can be replicated throughout most island ecologiies where eroding sedimnt flows are effecting coastal habitats in the tropics |

NICKEL MINE REHABILITATION IN THE PHILIPPINES Mary Noah Manarang established a vetiver based company in the Philippines over 10 years ago. Today the company, Biosolutions Inc, is active in many environmental mitigation programs. Recently the company completed a nickel mining project in the south of the Philippines. See the excellent quality of work performed by this company (MB1.7).  See more |
