Abstract: In this article, reed bed technology is described in brief.Reed bed technology is a waste water treatment which is natural purifying decentralized process. There are different types of macrophytes present in waste water. Thus various types of reed bed i.e Horizontal flow and Vertical flow type reed bed is use. Also many types of aquatic plant species is used in this technology for treatment of waste water. This technology gives an efficient and satisfying solution to the problem of domestic waste water.

Keywords: Horizontal flow, vaertical flow, Rophytes, Rhizosphere, NitrificationDenitrification, Root-Zone.
