As we are aware of the fact that the world is experiencing a huge explosion in terms of population growth and India is no behind. The increasing population lays stress on the fresh water and the demand increases which further produces wastewater as one of the end product. On an average, 80 percent of the world’s waste-water is released without proper treatment which leads to the matter of concern as water is a valuable resource and most basic need of everybody. India also only manages to treat 37 per cent of its total waste-water generation. Looking at the scenarios, waste-water recycling is very essential now when there are many cities in the world that are practicing waste-water recycling to supplement the fresh water demand of the city, hence it becomes very crucial to look recycled wastewater as a resource. This study aims to see the recycled wastewater as a resource for smart city management with the case studies and detailing of Lucknow smart city. The latest LSCL projects have stressed upon the wastewater recycling and using the treated water for secondary uses. The project of 1.5 MLD wastewater treatment plant at Hathi Park is taken as a case study and overall water infrastructure study of Lucknow was carries out keeping the scope and objectives in mind. For better knowledge, semi-structured interviews were performed with the officials and various on-field observations were also taken into consideration. Apart from water infrastructure facilities, water recycling potential to supplement fresh water demand and comparing various wastewater treatment technologies, sustainable options for wastewater recycling is also suggested. Conclusions includes the SWOT analysis on Lucknow Smart City in terms of water and wastewater infrastructure and facilities with some learning outcomes from the study and internship.
