AECOM announced today that it has been appointed by the Drainage Services Department of the Hong Kong Special Administrative Region Government to provide investigation, design and construction supervision consultancy for the relocation of Sha Tin Sewage Treatment Works (STSTW) to caverns in Sha Tin, Hong Kong. The consultancy’s lump sum fee is around US$32M while the total contract value, including site supervision costs, amounts to US$130M.
With a sewage treatment capacity of 340,000 cubic meters per day, the relocated STSTW will be the biggest cavern sewage treatment works in Asia when completed, serving a population of over 800,000 in Sha Tin. This project also marks a new milestone in large-scale cavern development in Hong Kong as part of enhancing land supply strategy to free up land for housing and other beneficial uses.
AECOM’s scope of works includes engineering and environmental impact assessments, design of sewage treatment process, all aspects of engineering and architectural design in relation to the sewage treatment works in caverns, preparation of tender documents and construction supervision. AECOM will also assist the government in public engagement activities and provide preliminary design for the upstream sewerage networks and pumping facilities related to the relocation of the STSTW to caverns.

A conference designed with the expert in mind, Cutting Edge's unique offering of specialized technical information won't be found anywhere else ... 29th to 31st October - Register TodayTo design a sustainable sewage treatment works located inside caverns that will meet the demands for the next several decades, AECOM’s cavern and process teams will work out advanced sewage- and sludge-treatment technologies to minimize the size of needed caverns, energy consumption, carbon footprint and sludge production, in order to optimize the cost of the entire life cycle. AECOM will organize pilot studies to ensure that state-of-the-art technologies work well for local sewage characteristics, including high salinity due to the use of seawater for flushing in Hong Kong.
“AECOM is delighted to deliver this mega-infrastructure project after the completion of our feasibility study,” said Sean Chiao, AECOM’s President, Asia-Pacific. “With our integrated capabilities and technical expertise, we provide a truly integrated service to handle this challenging project that will generate tangible benefits for the Hong Kong society.”
The investigation and design work are scheduled for completion in phases from 2017, and construction works will commence afterwards.
