exploit and affect the quality and quantity of the water resources. This has resulted in pollution of freshwater bodies due to increased generation of domestic waste, sewage, industrial waste etc. This paper reviews the Root Zone Treatment System which are planted filter beds consisting of soil gravel, sand and fine aggregate. This Technique uses a natural way to effectively treat domestic and industrial effluents. RZTS are well known in temperate climates and are easy to operate having less installation, low maintenance, and operational costs and incorporates the self-regulating dynamics of an artificial soil eco-system. This technology has been successfully running in several countries. Use of constructed wetlands can now be recognized as an accepted low-cost eco-technology, especially beneficial as compared to costly conventional treatment systems. There is a need to exploit this technology in a developing country like India to its maximum to gain its benefits and for sustainable development.
1.1 Objective of the research The objectives of this Project were to (1) Analyze and characterize the wastewater from sewage water. (2) To investigate the feasibility of applying a constructed wetland system to treat the Sewage waste water. (3) To compare the treatment efficiency of root zone system with conventional treatment plant.
1.2. The Research Motivations The cost effectiveness of all waste water treatment technologies needs to be improved new design of mechanical systems which addresses this concern are been introduce by treatment plant manufacturing industry. As it is natural process of water being recycled useful in various small scale works.

1. INTRODUCTION The term root zone emphases the life interactions of bacteria, the roots of the wetland plants, soil, air, the sun, and water. Root zone treatment is an engineered method of purifying wastewater as it passes through the artificially constructed wetland area.. The pollutants are removed by various physical, chemical and biogeochemical processes like sedimentation, absorption, and nitrification as well as through uptake by wetland plants. Root zone systems are reported to be most suitable for schools, hospitals, hotels and for smaller communities. The aim of this research is to study the effectiveness of the wetland plant Canna and Alocasia in the treatment of waste water generated. A pilot wetland unit was constructed on the campus grounds. Canna and Alocasia species were grown in the field with fresh water. Rows of plants were planted into the unit and subjected to waste water from the hostels and other campus buildings. The raw wastewater and treated wastewater were collected periodically and tested for quality. It is seen that this pilot unit is reducing the concentrations of TSS, TDS, BOD, COD by, respectively on an average. Root zone system

This study demonstrated that the designed subsurface horizontal flow constructed wetland system could be used for treatment of the campus waste water. A constructed wetland system can be an effective treatment facility for campus waste water. Regarding the performance achieved, the subsurface horizontal flow constructed wetland was able to reduce further the level of the main parameters. The treatment level was affected by the change of seasons, also by the variation in influent quality and quantity. The overall experimental results demonstrated the feasibility of applying sub-surface horizontal flow
