<p>Updated report of Oversight Committee in compliance of National Green Tribunal order passed in Original Application No. 490 of 2019 in Re: T. S. Singh Vs State of Uttar Pradesh with regard to prevention
Over two lakh residents of five villages in Outer Delhi have a stinking problem: living with a sewage treatment plant (STP) as their neighbour. The plant is part of the Capital's initiative to sanitise 189 villages with an "appropriate sewage disposal mechanism' by the end of 2009. The villagers moved the Delhi High Court recently, through a registered society called Gramin Uthan Avam Jankalyan, to halt the plant's construction. A Bench led by Justice T S Thakur, though, dismissed the petitioners' contention. The court observed that it was high time that sewage treatment in Delhi began on a "war-footing', and that there was no "real and compelling reason for interference in public interest'. The petitioners claim at 200 metres, the plant is too close for comfort, and would add to diseases and pollution in their area. "The STP will adversely affect the environment by breeding mosquitoes and spreading viral diseases and foul smell,' the petition says. The plant was meant for treating sewage of five villages

Constructed wetlands (CW) are being increasingly used worldwide to treat domestic wastewater by applying various technological designs. The systems are preferentially used due to simple technology in principle, reliable operating conditions and the potential to remove total nitrogen by simultaneous nitrification and denitrification. Oct-Dec 2007
Nitrogen is an important nutrient in domestic and industrial wastewater and its elevated concentration in the wetland promotes explosive growth of algae. The decomposition of the algae leads to an excessive growth of bacteria, utilizing and dissolved oxygen from water. This process of rapid algal growth leading to oxygen-starved waters is known as eutrophication.
The treatment and disposal of wastewaters is becoming more and more important as ever increasing population and urbanization threaten existing potable water supplies in many areas of the world. Worldwide natural wetlands are still used for watewater treatment but at present, the use of constructed wetlands is becoming more popular and effective around the world.
