[ Business case listing ](/global-case-studies " Business case listing") Using seawater as heat rejection for higher plant efficiency ### Up to 85 million kWh of energy savings per year ### 2 District Cooling System plants and 1 seawater plant ### 1.7 million m2 of cooling area ### The Challenge The Kai Tak Development is a large, highly complex project spanning a total planning area of over 320 hectares. This area covers the ex-airport site together with the adjoining hinterland districts of Kowloon City, Wong Tai Sin and Kwun Tong, which comprises of a mixed development of offices, shops, hotels and schools, as well as a new regional cruise terminal. ### Veolia's Innovative Solution **Seawater as heat rejection in a District Cooling System** The use of seawater as heat rejection can bring about higher plant efficiency and eliminate the risk of legionnaire disease. With technological innovations, Veolia's design is 10% less expensive than the tender reference design. Coupled with Veolia's best practice in O&M, an estimate of 30% lower life cycle cost can be saved, which amounts to 85 million kWh of energy savings per year, equivalent to a reduction of 59,500 tonnes of carbon dioxide emission per annum. ### Benefits for our client - Enhance environmental image - Enhance real-estate net space and urban landscape - Fast track construction by optimized design - Guarantee optimal comfort level and customer satisfaction - Ensure compliance with environmental and health & safety standards - Provide quality services to increase efficiency in operation and maintenance - Ensure the profitability of the system - Guarantee safety and continuity of operations ### Our Solutions in Energy, Water and Waste #### ENERGY - [Onsite Energy Management](< /what-we-do/energy-capabilities/site-energy-management>) - [Waste to Energy](/what-we-do/energy-capabilities/waste-energy) - [Energy Efficiency Solutions for Industrial Facilities](/what-we-do/energy-capabilities/energy-efficiency-solutions-industrial-facilities) - [Design-Build-Operate-Maintain (DBOM)](/what-we-do/design-build-operate-maintain-dbom-energy) - [On-Site Utilities Management](/what-we-do/site-utilities-management-energy) #### WASTE - [Hazardous Waste Management](/what-we-do/waste-capabilities/hazardous-waste-management-0) - [Integrated Service Offering](/what-we-do/waste-capabilities/integrated-service-offering) #### WATER - [Process Water Treatment](/what-we-do/process-water-treatment) - [Wastewater Treatment](/what-we-do/water-capabilities/wastewater-treatment) - [Reclaim Water Solutions](/what-we-do/reclaim-water-solutions) - [Water & Wastewater Plant Optimisation](/what-we-do/water-capabilities/water-wastewater-plant-optimisation) - [Design-Build-Operate-Maintain (DBOM)](/what-we-do/water-capabilities/design-build-operate-maintain-dbom-water) - [On-site Utilities Management](/what-we-do/site-utilities-management) [CONTACT A REPRESENTATIVE](/contact-us/contact-us-energy) *Veolia is uniquely positioned to service industry, government and commercial entities in improving performance, managing water, waste and energy.* [*Learn how*](https://countrysg.veolia.acsitefactory.com/what-we-do) [ ![](/sites/g/files/dvc2031/files/styles/content_push_teaser/public/image/2020/02/Jebel%20Ali%20LHW-2626_0.jpg.webp?itok=z62xUJnR) ](/global-case-studies/unicer-cogeneration-and-utilities-management "Unicer: Cogeneration and Utilities Management") Portugal [Unicer: Cogeneration and Utilities Management](/global-case-studies/unicer-cogeneration-and-utilities-management "Unicer: Cogeneration and Utilities Management") A CHP Gas Turbine to Produce Power, Steam and Hot Water while reducing environmental footprint [READ MORE](/global-case-studies/unicer-cogeneration-and-utilities-management "READ MORE")
