1. Reasons for Choosing
Constructed Wetlands (CWs)

CONCLUSION
(6) Unreliable power
supply
CWs will be able to cope with unreliable power supply.
•The CWs as such operate
without electric energy. The wastewater flows through the plant by
gravity. No aeration, recirculation pumping, etc is
required.
•By contrast, the
operation of convent. techn., such as AS, is fully
dependant on permanent and strong power supply.
