The aims of wastewater treatment are to reduce the amount of biodegradable matter and solids in the effluent, remove toxic materials and eliminate pathogenic micro-organisms. Waste stabilisation ponds and reed beds use natural systems to treat wastewater and are suitable for warm countries.
(precipitation, absorption and decomposition) that purify and treat the wastewater. While the system does not normally use machinery (except pumps if necessary to get wastewater to the CW unit/s against gravity), nor chemicals, the variety of natural mechanisms that do the water recycling and purification make CW very effective.
