Arup has been appointed by the Hong Kong SAR Government’s Drainage Services Department as the Consultant for the Harbour Area Treatment Scheme (HATS) Stage 2A – Upgrading Works for Stonecutters Island Sewage Treatment Works (SCISTW) and eight Preliminary Treatment Works (PTWs) on the Hong Kong Island.
HATS is one of the largest ever sewerage infrastructure projects in Hong Kong. HATS Stage 1, commissioned in 2001, provides treatment to about 75% of the sewage from urban areas around the Harbour. HATS Stage 2, a two-phase programme, provides additional facilities to convey all remaining sewage from the Harbour area to SCISTW for chemically-enhanced primary treatment (CEPT) and disinfection, and subsequent biological treatment. With a footprint of only 10 hectares, the SCISTW is designed to handle a sewage flow of 2.45 million m³ per day and serve a population of 5.7 million.
Arup is responsible for the design and construction supervision of the upgrading works of SCISTW and PTWs, responsible for civil, electrical and mechanical, process, environmental, control and automation engineering, as well as the overall project management and implementation of HATS Stage 2A.
