Water performs an important role in human life. Today water is becoming important and limited natural resources present on the earths surface. To deal with water scarcity and conservation, only reuse and recycle of the wastewater is the option. In recent days the construction and maintenance of the costly wastewater treatment plants cannot afford by many developing countries. They need any other techniques for treatment of wastewater at low cost. Centralized wastewater treatment system may not

Vermifiltration is one of the best method in which wastewater is treated by using earthworms. The mechanism involved in treatment of organic pollutants from wastewater is degradation by earthworms and adsorption by bed material. Eartworms increase the natural aeration and hydraulic conductivity by granulating the soil particles, due to this earthworms also known as environmental engineers. A treatment of domestic wastewater by using vermifilter is found to be more effective compared to trement by using non vermifilter. Overall review found that vermifiltration is an environmentally sustainable,socially acceptable and economically viable.
