Abstract - The main objective of the wastewater treatment plan implemented in Okhla district, Delhi, and to evaluate its effectiveness in mitigating the negative impacts associated with untreated wastewater.Okhla is a densely populated area in south Delhi that has seen significant real estate development in recent years. Sewage produces an unpleasant odour that causes illness in humans and animals. The problem is that sewage needs to be properly treated before it is disposed of on the land by not throwing it directly into natural resources and reusing the treated water, which ultimately reduces the overall demand for fresh water. Our primary objective is to generate liquid and solid waste that conforms to eco-friendly standards and can be safely disposed of or repurposed. Delhi generates about 744 million litres of wastewater per day, 80 percent of the 930 MGD that will serve Delhi's estimated population over the next 30 years. The focus of this paper lies in the analysis of wastewater generation in the Delhi area, and subsequently, the design of a treatment plant that aligns with population requirements. The proposed design aims to adhere to established standards and acceptable thresholds for treated effluent by developing various components of the wastewater treatment plant. The various components of the wastewater treatment plant are screening, grit chamber, disinfection tanks, biological reactor, sludge treatment and effluent discharge.
