Following the full commissioning of Harbour Area Treatment Scheme (HATS) Stage 2A in December 2015, all sewage generated from both sides of Victoria Harbour is conveyed to Stonecutters Island Sewage Treatment Works for centralized treatment and disinfection, the water quality in the Harbour has improved further.
However, the residual pollutions that discharge into the urban coastal waters, i.e. those not collected by our sewerage system due to various factors such as drain misconnections, and polluted surface run-offs from streets etc.,are still causing near shore pollution and frequent complaints on odour and visual impacts, in particular at areas that are easily accessible by the public and close to population and business centres. Following the commissioning of HATS Stage 2A, near shore pollution in Victoria Harbour has become our priority water quality problem. To deal with it will require measures that can effectively reduce or collect the many residual discharges from a wide range of small sources that are large in numbers in the urban area. A consultancy study on Further Enhancing Quality of Coastal Waters of Victoria Harbour was commissioned by the Environmental Protection Department in January 2016 to formulate recommendations and strategy to enhance the quality of the coastal waters of Victoria Harbour.
