The treatment of industrial wastes tends to be very specific depending on the nature of the waste. Pretreatment and then controlled disposal to sewer is the generally preferred method as the trade effluent is then diluted with domestic sewage which aids the treatment process. If the industrial site is not connected to the main sewer system then a dedicated plant can be made to work subject to strict controls and the water recycled for industrial use. Chennai has two large RO plants, producing high quality industrial process water, but these are fed with water from one of the city's sewage treatment plants.
