The city of Delhi has witnessed a continuous rise in its population and urbanization. This has opened new avenues to production and consumption, which consequently leads to the generation of more waste water and has become a serious public health and environmental concern. Residents of Delhi produce over 720 million gallons per day (MGD) of waste water that has a direct impact on health and basic living conditions when discharged in the natural environment. If this waste water is treated properly and managed responsibly, this sanitary and environmental challenge could transform into a resource to quench the city’s thirst for water. The latest technology allows efficient treatment solutions, including the possible reuse of treated waste water as water safe for horticulture activities and drinking purposes, as required.
Decentralized Plan for Reclamation of Water through the installation of Sewage Treatment Plants
An average person requires 135 Litres of clean water every day. Out of these 135 Liters, only 3-5 Liters of water is utilized for the purpose of drinking and cooking. All other activities like cleaning, gardening, firefighting, sanitation etc. do not need water that is considered safe for drinking. Recycled water could easily substitute for the purpose of such activities. For instance, a school with 2000 students as a unit needs 20,000 Liters of water every day out of which n only 5000-8000 Liters of water is actually required for human consumption. For all other purposes, wastewater treated and recycled through in situ Sewage Treatment Plants (STPs) can be utilized.
The Delhi@2047 partners can collaborate with government schools, buildings, parks, colleges, etc to manage their wastewater management and convert them into Zero Liquid Discharge buildings by installing Sewage Treatment Plants (STPs) within their premises. Recycled water will be used within the same premises. This effort will be a move towards developing a self-sustained water cycle.
Project Duration The project is an ongoing activity. Anyone can join the initiative at any time.
