Water scarcity and waste water management are serious problems experiencing in developing countries like India. So, waste water recycling should be encouraged where ever it is economical and safe. There are several techniques to treat waste water but constructed wet lands are one of the most efficient methods of treatment. Constructed wetlands for waste water have been effective economical and sustainable alternative for conventional waste water treatment technologies. A small-scale preliminary study is conducted on three constructed wetland units that have been constructed in NMREC, Divya Nagar, in which the influent is taken from STP Nalla Cheruvu, Uppal. The constructed wetland units have dimensions of 60 × 40 × 30 cm. The performance of these vertical flow wet land units is estimated with a withholding time of 48hours. The macrophytes used in the study are Colocasia, Cyperus rotundus and Cocos nucifera in three different units. Three field trials were carried out for the collected samples at the time of project for various characteristics like pH, DO, BOD, COD, T.S.S, T.D.S, Conductivity, Acidity, Alkalinity of the effluent are studied.
