For Sai Kung District Council Housing and Environmental Hygiene Committee on 15 November 2018 SKDC(HEHC) Paper No. 143/18 Port Shelter Sewerage Projects – Progress Update Purpose This paper serves to update Members on the latest progress of Public Works Project Item Nos. 4272DS – “Port Shelter sewerage, stage 2” and 4273DS – “Port Shelter sewerage, stage 3”. Background 2. At present, sewage from Port Shelter areas is often treated and disposed of by means of existing private treatment facilities (such as septic tanks and soakaway systems). These facilities are often ineffective in removing pollutants due to their proximity to watercourses or inadequate maintenance. Therefore, sewage from these unsewered areas has been a source of water pollution to the receiving waters of Port Shelter. 3. The Government has formulated a long-term programme under the “Port Shelter Sewerage Master Plan” to expand the public sewerage in Port Shelter areas. 4272DS – “Port Shelter sewerage, stage 2” and 4273DS – “Port Shelter sewerage, stage 3” are the relevant projects currently being implemented. Drainage Services Department (DSD) briefed and consulted Members on the above projects on 15 April 2008 and 31 March 2009, and updated Members on the implementation progress on 14 March 2013. Members expressed their support for the projects in the above meetings. Latest Progress 4. The 1st package of the above two projects, including the trunk sewers along Clear Water Bay Road and Razor Hill Road, as well as the sewerage works at West of Sai Kung town and in the vicinity of Fei Ngo Shan Road, was upgraded to Category A in June 2012 and re-titled as 4382DS – “Sewerage at Clear Water Bay Road, Pik Shui Sun Tsuen and west of Sai Kung town”. The works were substantially completed in May 2018. 5. Furthermore, the 2nd package of 4272DS, including the trunk sewer along Hiram’s Highway for the section between Marina Cove and Ho Chung, as well as along Ho Chung Road and Luk Mei Tsuen Road, was also upgraded to Category A in July 2015 and re-titled as 4410DS – “Trunk sewers at Hiram’s Highway”. The Page 1 construction works had been entrusted to Highways Department and the works are anticipated to complete by 2020. 6. The scope of works under 4272DS, 4273DS, 4382DS and 4410DS are shown in Attachment 1. Works Target to be Commenced in 2019 4272DS – Port Shelter sewerage, stage 2, package 3 7. The 3rd package of 4272DS includes the construction of sewerage works at Wong Chuk Wan, part of Wo Mei and Heung Chung, a local sewage treatment plant at Wo Mei to treat the sewage to be collected in the Wo Mei areas in future, as well as a sewage pumping station at Wong Chuk Wan. The scope of works for this package is shown in Attachment 2. 4273DS – Port Shelter sewerage, stage 3, package 2 8. The 2nd package of 4273DS includes the construction of sewerage works at Tai Po Tsai, Po Toi O, Tseng Lan Shue and Sam Long, a local sewage treatment plant at Po Toi O to treat the sewage to be collected in Po Toi O, as well as a sewage pumping station at Tseng Lan Shue.
