CASE STUDY Development of infrastructure for managing recycled water from Krishak Bharati Cooperative Limited (KRIBHCO) CASE STUDY Water management measures in port operations Objective To reduce freshwater footprint in a cost-effective manner (aligned with UN SDG12). Project description Adani Hazira Port Ltd (AHPL) successfully partnered Krishak Bharati Cooperative Limited (KRIBHCO) in a project that involved the utilisation of treated sewage for industrial purposes. Through a Memorandum of Understanding (MoU) between AHPL and KRIBHCO, AHPL committed to purchasing 2000 KL of treated wastewater from KRIBHCO. This collaboration has proven to be a cost-effective and environmentally friendly solution, significantly reducing AHPL’s freshwater consumption and its overall environmental impact. By utilising treated sewage water, AHPL demonstrates its commitment to sustainable practices and responsible resource management. Activity AHPL has undertaken the development of an 18 km dedicated pipeline, connecting KRIBHCO to facilitate the transportation of recycled water to AHPL. Methodology KRIBHCO sent treated wastewater to AHPL through a pipeline and charged as per agreement and for a minimum 2000 KL/ daily quantity. If the withdrawal of water exceeded 2000 KL/daily, it was charged extra on a per KL basis at a pre-agreed rate. In FY 2022-23, 4,96,416 KL recycled water was used in industrial applications. Estimated project benefits  Reduction in freshwater footprint  Availability of a good quality of water in a cost-effective manner  Lower capex and opex with respect to alternate options, i.e., desalination  Hassle-free operations of pumping and pipe network system for water reception Objective  Utilisation of desalinated water from the sea water reverse osmosis plant instead of freshwater for port operations.  Reusing the entire treated water of STPs, ETP and harvested rainwater for greenbelt development and maintenance. Project description The water requirements for port operations at AHPL were fully met through two sources: the Chennai Metropolitan Water Supply and Sewage Board and a desalination plant with a capacity of 100 MLD. The port operations did not rely on any freshwater sources such as surface water or bore water. Domestic wastewater from various sources, including canteen washing water and office building toilet flushing water, was treated in sewage treatment plants with a total capacity of 45 KLD. The treated water was then reused in gardening after ensuring that it met the required water quality standards. Additionally, an efficient effluent treatment plant with a capacity of 50 KLD was installed to treat liquid tank washings and the treated water from this plant was also reused for gardening. These measures showcase AHPL’s commitment to sustainable water management, minimising freshwater consumption and promoting water reuse in an environmentally responsible manner. Outcomes  MIDPL utilised desalination water for port operations  There was no dependence on fresh water.  Treated water from STPs and ETP was reused for gardening.  Harvested rainwater from the rainwater harvesting pond was used for gardening Ambuja Cement: 8x water positive ACC: 2x water positive AESL: Water positive for 30 substations and seven transmission line clusters AGEL: Water positive for plants with operating capacity above 200 MW For surface water usage in our hinterland power plants, we restrict water consumption to 2.35 m3/ MWh for FY 2022-23, well below the prescribed limit of 3.5 m3 /MWh set by the Ministry of Environment, Forest and Climate Change (MoEFCC) and stretched internal target of 2.50 m3/MWh Embracing zero-liquid discharge Zero liquid discharge (ZLD) encompasses rigorous water treatment and recycling, ensuring that no untreated wastewater is discharged into the environment. By embracing ZLD practices, we have markedly diminished our water footprint, conserving significant volumes of water. The Adani Portfolio implemented ZLD systems across mine sites, airports (Ahmedabad, Jaipur, Guwahati, Lucknow and Mangaluru), and the water business (nine sites of Adani Water Limited). Shri Karan Adani Whole Time Director and Chief Executive Officer, APSEZ At Adani Ports, responsibility is not only about doing more with less; it is also about making the world cleaner and safer. Our aim is to reinforce our position as a global leader in sustainable port operations. We are committed to become carbon neutral by 2025, and thereafter march towards our ambition of becoming Net Zero by 2040. ESG Report 2022-23 117 116 Adani Group
