The New Delhi Municipal Council (NDMC) is set to undertake a cleanup of the Nehru Park lake located in Chanakyapuri, New Delhi, using bio-remediation treatment. This initiative aims to enhance the water quality of the lake, which has been suffering from algal blooms. The NDMC has invited online bids for this specialized maintenance work, which is expected to last for eight months. The selected agency will be responsible for regular cleaning, removal of debris, maintenance of aquatic plants, and treatment of sludge. To purify the water, the project will employ liquid biological agents and algae filtration equipment. Additionally, a natural algaecide will be applied monthly to control algal growth. The project will also involve operating aeration machines and adding oxygen-enhancing compounds to improve water conditions. Bids are due by June 8, 2023, with an estimated project cost of ₹9,35,477 (approximately $11,300 USD). Eligible contractors must meet specific technical and financial criteria to participate.
