Umbakumba - Bore Rising Main and Associated Infrastructure Diversion and Sewer Pump Station Upgrade and New Sewer Rising Main

1.1 INTRODUCTIONUmbakumba is a remote aboriginal community located east of Angurugu near Little Lagoon and Port Langdon on the north east coast of Groote Eylandt. Umbakumba has a population of 549 people.A new subdivision is planned to the south west of the community. The location of the new subdivision has resulted in the diversion of the bore rising main and associated infrastructure.The bore rising main and associated infrastructure diversion is a priority and must not be delayed due to any sewer SPS and sewer rising main works.The existing sewage pump station (SPS) #1 was built in 1981. It was identified in the Strategic Indigenous Housing and Infrastructure program (SIHIP) that the SPS and rising main was undersized resulting in the SPS upgrade and new sewer rising main works.1.2 OBJECTIVESThe objectives of the project are to:· Divert the bore rising main and associated infrastructure to allow for the new subdivision,· Provide the remote community of Umbakumba adequately sized sewer headwork infrastructure for existing and future housing capacity, and· Provide opportunity for remote economic development and Aboriginal employment in full recognition of Northern Territory Government (NTG) policy.
