---------------------------------------------------------------------***--------------------------------------------------------------------2. ABBREVIATION Abstract - Nearly 97% of water is present in the form of sea, which is salty and cannot be used for domestic or municipal use. 2% of water is present in form of ice and glaciers. And only 1% of water is present for domestic used. Therefore there is scarcity of water in nature. [1] The construction cost and maintenance cost of wastewater treatment plants is more. Therefore there is necessity of replacement traditional method of treatment.[ 2] Therefore in the present study an attempt is made to know the efficiency of vermifilter for removing the parameters pH, removal of Biological oxygen demand and chemical oxygen demand of domestic wastewater. In this study waste water is treated using vermifilter containing earth worms and the results are compared with waste water treatment by traditional method, for the treatment of domestic wastewater. The domestic waste water is collected from hostels, apartment, kitchen food court, wash rooms of collage & school.
BOD (Biological oxygen demand), COD (Chemical oxygen demand), TS (Total solids), TSS (Total suspended solids), TDS (Total dissolve solids), E (Effluent), I (Influent).
3. STUDY AREAS Analysis of domestic wastewater come from hostels, apartments, kitchens, wash rooms of collage & school.
4. MATERIAL AND METHODOLOGY
It is the process of removing contamination from domestic wastewater soil using earthworms.

1.INTRODUCTION Nearly 70 to 80% of the water supply used by society was returns in municipal wastewater in the sewer system as sewage. [1] The domestic wastewater contains high pH, COD, BOD, and solids - both dissolved and suspended solids. The domestic wastewater has to be treated to reduce the pH, COD, BOD before discharging into the environment (rivers and oceans). Aerobic bacteria will consume more dissolved oxygen (DO) from the river/ ocean water to decompose this organic material thereby depleting the DO values. [3]

Treatment of domestic wastewater by vermifilter have been found that effective in removing pH, Turbidity , BOD, COD , TDS and (TSS) from domestic wastewater by the general mechanism of biodegradation of organic wastes . It is found that treatment of domestic wastewater by vermifilter no need of aeration, chemicals, whole process is odorless and no sludge is formed.
