Nature's Green Engineer:
The Vetiver System is a simple, low-cost, and effective solution for a wide range of environmental and engineering problems. It is based on the use of a unique plant, Chrysopogon zizanioides, commonly known as vetiver grass. This remarkable plant has a massive, deep, and fast-growing root system that makes it highly effective for soil and water conservation, slope stabilization, and land rehabilitation.

Water Pollution Control
Water Pollution Control
Vetiver grass acts as a natural biofilter, removing pollutants, heavy metals, and excess nutrients from water bodies and soil. Its dense root system absorbs and traps contaminants, while slowing water flow to allow sediments to settle.
For water pollution control, the Vetiver System is used in:
Constructed wetlands – to filter and treat wastewater before discharge.
Riverbanks & streams – to trap sediment and absorb pollutants from runoff.
Agricultural drainage canals – to reduce fertilizer and pesticide contamination.
Fish ponds & aquaculture farms – to improve water clarity and reduce ammonia/nitrogen buildup.
Urban stormwater retention ponds – to remove suspended solids, heavy metals, and oils.
Industrial wastewater treatment sites – to absorb toxins and heavy metals before release.
Sewage treatment lagoons – to control odor and improve effluent quality.
Riparian buffer zones – to prevent polluted runoff from entering waterways.
Water reservoirs – to prevent nutrient pollution that can cause algae blooms.
Flood-prone lowlands – to slow runoff and filter contaminants naturally.
Natural filtration of pollutants – Deep, dense root systems trap sediments and filter suspended solids from runoff before reaching waterways.
Absorption of harmful chemicals – Roots absorb excess nutrients such as nitrogen and phosphorus, preventing eutrophication in rivers and lakes.
Reduction of heavy metals – Proven to uptake and store toxic elements like arsenic, lead, mercury, cadmium, and chromium from contaminated water.
Improves water clarity – By trapping sediments and filtering particulates, vetiver helps restore transparency in ponds, lakes, and rivers.
Prevents algal blooms – Reduces nutrient overload, which limits the growth of harmful algae and cyanobacteria.
Controls pesticide & fertilizer runoff – Captures and degrades agricultural chemicals before they pollute downstream water bodies.
Bio-remediation in industrial wastewater – Can treat effluents from factories, tanneries, and mining operations, reducing pollutant loads.
Restores aquatic habitats – Cleaner water improves conditions for fish, amphibians, and other aquatic life.
Cost-effective water treatment – Low maintenance and long lifespan make it a sustainable alternative to expensive treatment systems.
Climate-resilient solution – Thrives in droughts, floods, saline, and polluted conditions, ensuring year-round pollution control.
Soil Recovery
Soil Recovery
Vetiver is a natural ally for soil restoration—turning barren, degraded, or polluted landscapes into fertile, resilient land. Whether reclaiming mining sites in Australia or iron spoil dumps in India, its combination of deep anchoring roots, environmental tolerance, and biomass benefits makes vetiver a compelling, eco-smart recovery tool.
For soil recovery, the Vetiver System is used in:
Abandoned mining land – to rehabilitate nutrient-depleted and contaminated soils.
Quarry sites – to stabilize loose spoil piles and regenerate soil structure.
Construction sites – to restore compacted or disturbed soil after building projects.
Landslide-affected slopes – to anchor soil and promote regrowth of vegetation.
Overgrazed pasturelands – to restore degraded grasslands.
Saline or sodic soils – to reclaim soils affected by salt or alkaline build up.
Deforested hillsides – to bring back topsoil and support reforestation.
Waste disposal areas / landfill covers – to hold soil in place and improve surface stability.
Agricultural land degraded by erosion – to rebuild fertility and prevent further loss.
