Sewage Treatment Plant in President´s Estate

It took around one year and three months to build the first ever Sewage Treatment Plant (STP) built in President´s Estate. The STP has the capacity to treat 20 lakh litre of sewage per day and is constructed as per the recommendations of the Comprehensive Conservation Management Plan prepared by INTACH. The water intake is around 16-18 litre per day and is sourced from NDMC and others. Out of this around 80% becomes sewage. The water from the treated sewage would be used for horticulture purposes in the President Estate, which is spread over 190.5 acre of greenery, including the famous Mughal Gardens. The project includes a Wetland which has been innovatively designed and planted with various species of trees, shrubs etc. This Wetland will support the flora and fauna in the region. The capacity of the existing Dalikhana Lake which serves as the collection point of treated water has been increased three times from its earlier capacity and is now a water body of 5 million litres. This would serve in addition as a habitat for water birds in Northern Ridge area which lacks such water bodies. 18000 fishlings have also been added to the Dalikhana Lake.

IIT Delhi was the technical consultant for the Plant. The construction, operations and maintenance has been entrusted to L&T. The STP is based on the Extended Aeration System with Anoxic Zone for De-nitrification and sub-Surface Constructed Wetland (SSCW) with UV Disinfection Unit.
