Project Profile – Woodland Hills

Facility: Closed Landfill

Location: Sulphur, Louisiana

Owner/Operator: Republic Services

System: Leachate Phyto-Utilization with Vetiver Grass

Installation Year: 2014

Design: Rows of vetiver plants over 1.2 acres

Phyto Systems Utilize Leachate as a Resource

Our phyto-utilization systems use fast-growing and non-invasive plants to consume liquid waste in a GREEN and sustainable way in order to greatly reduce or eliminate the need for other, more costly disposal methods.  The systems are engineered to pump leachate from a pond or tank through a fully automated pre-treatment and distribution process and up to a field to irrigate the rows of vetiver.  Vetiver plants then utilize the leachate, normally considered a waste, as a resource by absorbing the needed moisture and contaminants, which act as micro and macro nutrients to fuel plant growth.

The Woodland Hills project has been a success since its installation in 2014.  As of September 2018, it has processed more than 3,400,000 gallons of leachate and the plants are looking great!  The system has reduced the facility’s carbon footprint by sequestering CO2 and avoiding tanker truck emissions, as well as create significant long-term savings for the facility and habitat for wildlife.
