Wastewater (WW) management is the major concern to focus for achieving sustainable development in developing countries. Constructed wetlands are the economical and environmentally benign method, which has advantages for the economy, environment, and society. A detailed case study of rural WW treatment technology, focusing on constructed wetlands, is presented. The inlet and outlet of existing technologies in Tepla village, Ambala district, Haryana, was sampled extensively, in which E. coli, TDS, COD, BOD, TSS, pH, EC, and salinity were the key parameters investigated. The study found E. coli, TDS, and EC were beyond the permissible limit in the site, suggesting a health and environmental risk. The study found that due to behavioural issues of villagers, it was not working properly as they were polluting the inlet by throwing the solid waste directly. To tackle these difficulties, the work focuses on the incorporation of participatory rural appraisal (PRA) as a vital approach to engage and empower the community.
