3 WSAA Product Appraisal Overview of WSAA The Water Services Association of Australia (WSAA) is the peak industry body representing the urban water industry. Our members provide water and sewerage services to over 20 million customers in Australia and New Zealand and many of Australia's largest industrial and commercial enterprises. Based around our vision of 'customer driven, enriching life', WSAA facilitates collaboration, knowledge sharing, networking and cooperation within the urban water industry. We are proud of the collegiate attitude of our members which has led to industry-wide approaches to national water issues. WSAA can demonstrate success in the standardisation of industry performance monitoring and benchmarking, as well as many research outcomes of national significance. The WSAA Executive retains strong links with policy makers and legislative bodies and their influencers, to monitor emerging issues of importance to the urban water industry. WSAA was formed in 1995 as a non-profit organisation to foster the exchange of information between industry, government and the community, and to promote sustainable water resource management. The urban water industry is committed to anchoring its services to customers' values, and to enrich communities where water services have broad economic, environmental and social values. In line with this our main activities focus on four areas: 1. influencing national and state policies on the provision of urban water services and sustainable water resource management 2. promoting debate on environmentally sustainable development and management of water resources and the community health requirements of public water supplies 3. improving industry performance and establishing benchmarks and industry leading practices for water service processes; and 4. fostering the exchange of information on education, training, research, water and wastewater management and treatment and other matters of common interest.
