ABSTRACT:
A bioretention system and method are provided for removing phosphorus, nitrogen and other materials from effluent such as wastewater and stormwater. The system and method can include a filtration media comprising water treatment residuals and other fill such as soil. Plants can be growing in the soil. The system can also include a drainage system to regulate outflow, to function during both low and high throughputs of water.
