Harbour Area Treatment Scheme (HATS)
The Government implemented the Harbour Area Treatment Scheme (HATS), for handling the sewage generated from both sides of Victoria Harbour. Through a large-scale deep sewage tunnel collection system, the HATS collects sewage from both sides of Victoria Harbour and transports it to the Stonecutters Island Sewage Treatment Works for centralised treatment and disinfection before discharge. Spanning over 20 years, the HATS project was implemented in two stages and is the largest sewage treatment infrastructure project in Hong Kong's history. Since the full commissioning of HATS in December 2015, the water quality of the Victoria Harbour has been enhanced.
