Water, Sewage & Effluent May June 2019 - Page 8

6 International water experts will meet at the IWA Water and Development Congress & Exhibition in Colombo, Sri Lanka, from 1 to 5 December 2019, to progress solutions and the uptake of innovation needed to achieve the United Nations Sustainable Development Goals (SDGs) with the dedicated water goal SDG6 by 2030. Developing and emerging economies face the greatest threat to their water security where increasing water scarcity and deteriorating water quality remain critical issues. Global changes such as rapid urbanisation and climate change amplify these concerns. The need for safe treatment of wastewater is fundamental to the well-being of societies, economies and the environment. In a globalised and connected world, such issues cannot be dealt with separately but must be tackled together. “With 2.1 billion people globally still lacking access to safely managed water supplies and 4.5 billion without safe sanitation, there is an urgent need to accelerate the diffusion of knowledge, innovation and sustainable water solutions,” says Diane d’Arras, president of the International Water Association (IWA). “Transformational change is required to deliver water and sanitation for all within the upcoming 11 years under the Sustainable Development Goals agenda.” It is in response to these needs and opportunities that more than 3 000 water experts from around the world will meet in Colombo, Sri Lanka in December this year. The IWA Water and Development Congress & Exhibition series focuses on the transition to new ways of managing water resources and delivering water services in emerging economies. This 2019 edition, organised by IWA together with the host country Sri Lanka and the National Water Supply & Drainage Board, deals in particular with drinking water treatment supply, faecal sludge and wastewater treatment for resource recovery, urban and city water services, integrated water management solutions at city and basin scale and cross-cutting areas that contribute to the achievement of dedicated water goal SDG 6. "We need to transition to a circular economy approach, where we try to reuse water as many times as possible and where we endeavour to generate value from the waste streams, particularly energy and nutrients,” says Kala Vairavamoorthy, executive director of the IWA. Global water experts to tackle SDG6 According to the World Bank, the most polluted river in the world is Indonesia’s Citarum river, which has more than 200 textile factories along its bank. The IWA Water and Development Congress & Exhibition in Asia In the Asia Pacific region, home to two-thirds of the world’s poor, water quality is at a critical stage, as growing volumes of untreated wastewater from households, cities, agriculture and industry continue to be released into the natural environment. This links to the region’s role in IWA (International Water Association: www. iwa-network.org / www.iwa-connect.org) and the globalised world. As an example, 20% of our global wastewater comes from the textile industry and the dyeing industry is the second largest water polluter worldwide, according to UN Environment. The fashion industry in Asia continues to grow to meet global demand. According to the World Bank, the most polluted river in the world is Indonesia’s Citarum river, which has more than 200 textile factories along its bank. Over the years, the Indonesian government has established several ongoing clean-up efforts as a clean river brings countless benefits to the ecosystem, economies and societies. “Unprecedented challenges offer opportunities to implement a new paradigm for sustainable water and wastewater management,” comments Vairavamoorthy. “This is particularly the case in emerging economies, where more than 85% of wastewater is discharged untreated into rivers, lakes and oceans. The next 10 to 20 years will be the Water Sewage & Effluent May/June 2019 golden age for solutions for wastewater and sanitation provision in emerging economies. The potential to innovate and implement a step change in approach is great and will result in improved health of our societies and the environment.” In Asian countries, as with emerging economies in general, there is an urgent need to accelerate diffusion of innovation and uptake of sustainable water solutions, products and services. This can catalyse the transformation required to deliver water and sanitation for all by 2030 under the Sustainable Development Goals agenda. The 2019 IWA Water and Development Congress & Exhibition in Colombo, Sri Lanka is the international biennial water event with a special focus on developing and emerging economies – some countries with the most significant water challenges now and in the future. The 2019 congress is the second of the congress series organised by the International Water Association taking place in the Asia region. Congress participants and exhibitors will explore how policies, regulation, new financial models, innovative research and best practices from around the world can help meet the growing threats to both water availability and water quality and make progress towards achieving the human rights to water and sanitation.
