ATAL Engineering Wins HKD 4.63 Billion Contract for Electrical and Mechanical Works in Sha Tin Sewage Treatment Works Relocation Project
07 Nov 2025
The Drainage Services Department (DSD) of Hong Kong has awarded ATAL Engineering Limited a HKD 4.63 billion contract for the Relocation of Sha Tin Sewage Treatment Works to Caverns - Electrical and Mechanical Works for Sewage Treatment Facilities and Associated Works, a historic infrastructure development. The agreement, which was signed on September 22, 2025, is among the biggest engineering projects in the history of wastewater management in Hong Kong.Project SynopsisA major project to improve the city's sewage treatment capacity and environmental resilience while freeing up valuable land for urban development is the relocation of the Sha Tin Sewage Treatment Works (STSTW) to caverns. In order to support cutting-edge sewage treatment operations inside specially constructed rock caverns, the project entails the design, supply, installation, and commissioning of sophisticated electrical and mechanical systems.The Electrical and Mechanical (E&M) works package will be managed by ATAL Engineering Limited, which will guarantee the delivery of reliable, energy-efficient, and ecologically sustainable systems to manage large-scale wastewater treatment in cramped underground areas.Contract Specifics Contract Amount: 4,633,479,872 HKD September 22, 2025 is the contract date. Buyer: Hong Kong Government's Drainage Services Department (DSD) ATAL Engineering Limited, the supplier Reference to Notice: DE/2024/10 The TOT reference number is 21159284. The project, which is a vital part of Hong Kong's long-term sewage infrastructure modernisation strategy, will be supervised by the DSD's headquarters, which is situated at 43/F, Revenue Tower, 5 Gloucester Road, Wanchai.Project SignificanceOne of the first examples of sustainable urban planning is the Sha Tin STW's relocation to caverns. Hong Kong is reclaiming more than 28 hectares of surface land for community use, urban redevelopment, and green areas by subterraneanising large-scale treatment facilities.The government's emphasis on utilising local expertise in high-tech engineering solutions, particularly in projects requiring complex system integration, automation, and energy optimisation, is demonstrated by the E&M contract given to ATAL Engineering. Additionally, the move will strengthen Hong Kong's sewage management system's overall resilience, lessen its negative effects on the environment, and improve odour control.About the company ATAL Engineering LimitedLeading Hong Kong-based engineering company ATAL Engineering Limited is an expert in infrastructure solutions, environmental engineering, and electrical and mechanical contracting. ATAL is renowned for its technical innovation and sustainability-driven approach, and it has decades of experience delivering large public works projects. Large-scale infrastructure projects for utilities, transport systems and government agencies in Hong Kong and the surrounding area have previously been completed by the company.Impact on the Environment and StrategyWhen the relocated Sha Tin STW is finished, it will rank among the biggest cavern-based sewage treatment plants in the world. This ground-breaking project will establish new standards for urban environmental engineering and offer insightful information about how densely populated cities can strike a balance between sustainable land use and infrastructure growth.To sum upAn important turning point in Hong Kong's efforts to develop sustainable urban infrastructure has been reached with the award of the HKD 4.63 billion E&M contract to ATAL Engineering Limited. Hong Kong's standing as a world leader in sustainable city development is strengthened by the Relocation of Sha Tin Sewage Treatment Works to caverns, which serves as an example of creativity, environmental responsibility, and engineering prowess.
