Stage 2A - Needs for the Project

Whilst remarkable water quality improvements have been seen at the middle and eastern areas of theharbour, the western harbour, notably in the area of the Tsuen Wan beaches, is still subject to the impacts of the large volume of treated effluent (without disinfection) discharged from the Stonecutters lsland Sewage Treatment Works. The harbour is also affected by some 450,000 cubic metres of virtually untreated sewage that is discharged from the remaining parts of Hong Kong Island every day. Intercepting these sewage flows for proper treatment under HATS Stage 2A is absolutely essential.
