Abstract
A system and method of sewage treatment which comprises the sequential steps of: (i) subjecting waste water to be treated to a primary settling means to remove settleable solids and suspended solids and produce settled effluent; (ii) passing the settled effluent through a peat filter; and (iii) collecting the effluent from the peat filter and passing it through a sub-surface constructed wetland.

A method of sewage treatment comprising the sequential steps of:
- (i) subjecting waste water to be treated to primary settling to remove settleable solids and suspended solids and produce settled effluent;
- (ii) passing the settled effluent through an aerobic filter medium consisting entirely of sphagnum peat;
- and
- (iii) collecting the aerated aerobic effluent from the peat filter and passing it through a sub-surface constructed wetland, which exposes the aerated aerobic effluent to anaerobic conditions prior to discharge.
A system for sewage treatment comprising a primary settling means, a filter medium consisting entirely of sphagnum peat and a sub-surface constructed wetland in which anaerobic conditions predominate, means for passing settled effluent from the primary settling means to the peat filter and from the peat filter to the sub-surface constructed wetland.
