after a primary treatment (grid + Imh<strong>of</strong>f septic tank), flows <strong>in</strong>to an horiz<strong>on</strong>tal subsurface flow<br />
system as sec<strong>on</strong>dary treatment (1 st stage), then <strong>in</strong>to a vertical subsurface flow system (2 nd<br />
stage) and <strong>in</strong>to an horiz<strong>on</strong>tal subsurface flow system aga<strong>in</strong> (3 rd stage). At least, wastewater is<br />
received by a free water system as a tertiary treatment (4 th stage). The free water system is<br />
used as polish<strong>in</strong>g stage for dis<strong>in</strong>fecti<strong>on</strong> and enhanced denitrificati<strong>on</strong>. It is c<strong>on</strong>ceived <strong>in</strong> order<br />
