Poplar trees have been used successfully at a number of sites to beneficially reuse water and nutrients from recycled water and biosolids produced at wastewater treatment facilities. In doing so, municipalities have found more cost effective solutions than the conventional treatment alternatives to meet stringent discharge limitations. Similar to other conventional treatment alternatives, however, poplar tree systems also need to be designed and operated carefully to ensure that applied water and nutrients are managed responsibly. The planning and design of these systems requires good science and engineering while operations require continual monitoring and adaptive management.
