The
constructed wetlands, a system of six deep plant ponds and twelve
shallow plant beds, is the core of the entire purifying system.
A number of processes work together to make the water suitable for
plants to thrive and allow them to absorb pollutants and transform
pollutants into nutrients. The
plant ponds and beds offer a model where the mutual interactions
of plant and animal life and microbes can b observed and the quality
of water at different sites at certain times can be monitored.
