Sewage whether treated or untreated, ultimately discharge in lakes, rivers, streams, and oceans. We consider groundwater as pure, but unfortunately, sewage is one of the major reason behind wastewater associated diseases. Nearly 78% of the water flows back to the environment without any treatment. This can lead to a numerous health and environmental problems so it is better to treat wastewater before disposal and further proper management can help in meeting the public’s water demand. As per today’s scenario, number of innovations are required to operate treatment plant at high efficiency because of increasing domestic, commercial, and industrial waste. And this rise is taking place due to several reasons – urbanization, increasing population, economic development, and improved living conditions etc. Nowadays people of both urban and peri-urban areas are using waste water to irrigate their crops, often because they do not have any alternate source of irrigation water. New technologies are continuously being introduced in sewage treatment plant to exhibit good performance. The paper focuses on reviewing the various sewage treatment methods and their results.
