Subsurface drip technology is being applied to wetlands in a resourceful manner in order to solve several treatment situations. These situations include aeration of an 11,000 m3/d (3 × 106 gpd) remedial treatment wetland at a petroleum polluted site;
flow distribution across a vertical flow wetland at temperatures below −25°C; flow distribution into a horizontal flow wetland of septic tank effluent from a single-family home; and, aeration of a subsurface flow wetland treating cheese-processing wastewater in Minnesota, USA.
