9th IWA Specialist Conference on Waste Stabilisation Ponds On behalf of the Organising Committee of the 9th IWA Specialist Conference on Waste Stabilisation Ponds 2011, we would like to invite you to participate in the main international conference on the dynamics, hydrology, biology and sociology of Waste Stabilisation Ponds and associated developments in waste water management. This conference is the 9th in the series having recently been held in 2009 (Belo Horizonte, Brazil), 2006 (Bangkok, Thailand) and 2004 (Avignon, France). In 2011 the conference will be held in the relaxed city of Adelaide, Australia. The Aim of the Conference The aim of the 9th international conference on waste water management in rural and urban areas is to provide a forum for the exchange of the most recent ideas, techniques and experience in all areas of system management that could contribute to more efficient and sustainable use of waste water. Professionals from around the world (water managers, regulators, consultants, scientists, environmentalists, researchers and providers of equipment and solutions) should attend the conference as it is one of the key international events in waste water management and re-use efficiency. The technical, institutional, legal, environmental, economic and service quality perspectives will be comprehensively examined in order to identify the main driving factors, problems and solutions to the efficient re-use and management of waste water in rural and urban areas. Topics covered will include: This conference will focus on techniques for the delivery of the maximum volumes of clean, environmentally safe, treated waste water for amenity and agricultural purposes, using minimal energy inputs and having low maintenance requirements. It is envisaged that presentations could fit specific topics under the following headings: • Performance of WSP • Biology • WSP applications for smaller communities • WSP and sustainability issues - carbon, energy reduction - bio energy production • Public health microbiology • WSP case studies • WSPs and their integration with other treatment technologies
