THE NEW A.W.W.A. SIXTH FEI MAN AND WATER was the theme of the Association's sixth Biennial Convention held from April 30th to May 4th, 1974 at Melbourne's Exhibitions Buildings; a most imposing building constructed in the late 1870's and now classified 'A' by the National Trust.

The Convention sought to explore all, aspects of its chosen topic from conservation of water to complete recycling of waste water, and attracted a registration of 335 delegates accomp·anied by 93 ladies, with all States being well represented as the following table indicates:

Registration and accommodation was arranged by the Victorian Water Commission and as full co-operation was obtained from the Motels involved the affairs of most delegates could be easily arranged. However, late registrations produced the usual chaos. The Convention was opened by the Hon. W. A. Borthwick, Victorian State Minister for Conservation. The Minister welcomed all delegates and overseas speakers and in his opening remarks expressed pride in the way in which Australia's expertise and technology was keeping abreast with that which exists overseas. He went on to say that a few years ago the risk of eutrophicatiori of Port Phillip Bay had led to a decision to convey treated sewage effluent of high quality for disposal in Bass Strait, the wisdom of which decision, although not generally well receiVed initially, would undoubtedly be appreciated by future generations. Prof. Eckenfelder of Vanderbilt University, Nashville, Tennessee, U.S.A. then gave an entertaining address in which he explained the role of "bugs" in sewage disposal. His grass-roots approach to the subject kept the ladies amused and gB.ve all present a primer course in sewage treatment by biological means couched in refreshing phraseology. · The Convention Committee set out to combine Australian knowledge with overSeas experience in the technical sessions and succeeded in achieving a most rewarding combination. Papers and presentation by Australian authors were of great interest and high standard. They were complemented by contributions from visiting experts of international standing, including: Prof. W. Eckenfelder, Mr. J. D. Parkhurst (Pres. W.P.C.F.), and Dr. B. Bell of the USA; Dr. B. Gustaffson of Sweden, Dr. A. Downing and Dr. A. Coleman of the U.K. and Dr. G. Mohanrao of India. In particular, the Paper by Dr. Mohanrao - "Problems of Wastewater Control in India" - provided a marked contrast to the accounts of the high-powered technical advances in technology, by setting out the many and fundamental problems a country such as India has to overcome in the water and wastewater field. The keynote address was delivered by Professor Eckenfelder and was titled "Progress towards Complete Recycling of Wastewater". His informative, objective and often witty narrative served to form a solid tou·ndation for the ensuing three days of technical sessions. The introduction of_a Forum session provided a most successful innovation at a Technical Convention of this nature. 'Effluent Quality Standards - have we reached the practical limit - or passed it?' - was the topic introduced and discussed by members of the panel comprising Professor Eckenfelder, U.S.A., Dr. Mohanrao, India, Dr. Downing, U.K., Mr. Parkhurst. U.S.A., and Professor Shap.iro, U.S.A. (now in Victoria with the Westernport Study Authority). This subject proved to be most provocative and stimulated the audience into lively and constructive participation. It is hoped that selected sections of the discussion will be printed and circulated during the coming months.
