<p>A reed bed sewage treatment system comprises a series of generally parallel spaced liquid-conducting channels (1,2), reed bed support medium (soil) (4) extending between neighbouring channels, means (6) for delivering sewage to be treated to alternate ones (1) of said channels wherefrom it can flow outwardly through said medium to connect as treated liquid in other channels (2) between said alternate channels, and means (7) for conducting said treated liquid from the system. The channels may be defined between upstanding stone-filled gabions (3). Impervious plates (11) reduce short circuit surface flows between channels (1) and (2). <IMAGE></p> |
