Title: Key Issues in Planning Submarine Outfalls for Sydney, Australia
Abstract:This paper describes three large tunnelled submarine ocean outfalls, planned to safely discharge primary effluent from about two-thirds of the regional population of Sydney, Australia into deep ocean ...This paper describes three large tunnelled submarine ocean outfalls, planned to safely discharge primary effluent from about two-thirds of the regional population of Sydney, Australia into deep ocean water. Environmental and investigation aspects are dealt with briefly. Interesting aspects of design and construction planning are described. The design includes the handling of special hydraulic problems such as dilution and salt water removal. The construction planning foreshadows the extensive use of tunnelling machines including roadheaders and a full face tunnel boring machine. The offshore engineering describes the design and testing of innovative G R P risers and diffusers, and their intended installation by a semi–submersible drill ship using standard oil field techniques. The cost estimate and program is included.Read More
