At The Temple House, The Opposite House and The Middle House, higher flow-rate kitchen faucets were replaced with faucet aerators to decrease water usage, collectively reducing water 3 consumption by over 3,250m . Rainwater Recycling at INDIGO INDIGO’s existing grey water system collects high-quality wastewater and rainwater to make grey water for toilet flushing and greenery irrigation. Cutting-edge treatment technology can effectively treat sewage water, allowing it to reach grey water or even pure water standards for use in cooling towers. In 2022, INDIGO built a sewage water recycling system, further improving our water savings and reducing wastewater discharged into the municipal pipework system. 3 When operating, the system will have the capacity to save up to 85,000 m of water per year. Water Categorisation and Sub-metering Efforts at our Chinese Mainland Portfolio In 2022, our Chinese Mainland portfolio completed the water sub-metering installation project. By breaking down landlord water consumption into specific categories, such as air conditioning, water features, bathroom faucets, cleaning and others, we gain increased visibility on water consumption patterns and system demands. This allows us to optimise water usage and strengthen our efforts to create better water stewardship. SUSTAINABLE DEVELOPMENT REPORT 2022 212
