About LET

With 14th IWA LET Conferences successfully held worldwide since 2003, LET 2018 will represent a remarkable milestone that it will come to Mainland China for the first time. As the Conference President, I would like to invite the experts from academia and water industry from all over the world to participate in the LET Conference 2018 in Nanjing, to exchange ideas on water technologies and inspire innovations and implementations.

China now is recognized as the most dynamic and largest market for water sector in the world. With the rapid economic growth in the past decades, water issues have presented critical challenges for the sustainable urban development in China, including drinking water supply, municipal wastewater treatment, industrial wastewater treatment and basin management. Opportunities, however, always coexist with challenges. The principle “lucid waters and lush mountains are invaluable assets” raised by Chinese President Xi Jinping, along with the eco-civilization construction, demonstrates the resolution from the central government to tackle water problems in China. Under such background, both public and private funded water projects are blooming and the demands on innovative technologies of water and wastewater treatment are experiencing unprecedented upsurge.

Nanjing is the capital city of Jiangsu Province. As a developed region rich in freshwater resources, Jiangsu Province, the home to over 2,000 environmental companies, is leading the technology innovations on water and wastewater treatment and, is proactive in developing novel water and wastewater technologies to achieve the goals and plays a leading role in water and wastewater technology innovation at the global level.

I am confident that the IWA LET Conference 2018 will offer all the delegates a unique opportunity to discover China’s ideas and experiences in water management and to share knowledge on the development of cutting-edge water and wastewater technologies.

I look forward to meeting you in Nanjing, the historic and dynamic city in China!

Jiuhui Qu, Conference President

No other resource is as important for life as is water, and the importance of clean water for global health and economic development cannot be overstated. For example, over 650 million people worldwide currently lack access to safe water, and water remains a major limiting factor for food and energy production in many parts of the world.  Furthermore, frequent detection of priority pollutants and contaminants of emerging concern in drinking water sources, sewage treatment plant effluents and natural waters underscore the need to enhance water treatment infrastructure. Accordingly, technological innovation to economically treat and reuse water, recover resources from used water, and make clean water more accessible to more people is of the greatest challenges (and opportunities) of this century.

On behalf of the Programme Committee, I invite researchers and practitioners worldwide to submit abstracts for the 15th LET conference in the beautiful historic city of Nanjing, China. Your participation – as presenters and delegates – will ensure that LET maintains its hallmarks: the highest quality for a technical content that reflects scientific rigor and societal relevance (r2), and the greatest opportunity for networking. The programme will be organized by themes, which are described in this Call. The Programme Committee is inviting recognized world leaders to anchor each theme, and it seeks additional platform speakers, workshop leaders, and poster presenters to complement the invited speakers. All abstracts are peer reviewed to ensure high quality and thematic consistency. Indeed, the programme will feature only the “best of the best.” I encourage your participation and look forward to welcoming you to this beautiful center of culture, education, research, and tourism.

The IWA Leading Edge Conference on Water and Wastewater Technologies (LET) has built a world-class reputation as the forum for leading researchers to share and debate the pioneering science, technological innovation and leading practices that will provide solutions to water challenges, old and new. Those challenges are immense.

Fast growing cities, with rapidly expanding populations and industrial bases, are challenging the traditional model of large-scale centralised technology and infrastructure solutions; wastewater, the majority of which is discharged untreated into nature, presents a significant opportunity for building a circular, green economy; the increased presence of chemical micro-pollutants, including pharmaceuticals, pathogenic microorganisms and antibiotic resistant bacteria, threatens the quality of water around the globe.

This 15th LET, taking place in Nanjing, China, will be a window into the potential of the water sector to innovate for a sustainable, water-wise future. Nanjing’s economy is mainly based on electronics, cars, petrochemicals, iron and steel, and power, the “five pillar industries”. Coupled with Nanjing’s commitment to the national Sponge City Initiative, it makes an ideal venue to discuss research for municipal and industrial applications.

Over recent years, China has invested significantly in the water sector, and delivered rapid technological innovation in advanced materials. Nanjing provide’s the perfect backdrop for discussions on anticipating future developments for the water sector, fostering ground-breaking ideas, and enabling their rapid practical application.

LET is the place where individuals who share a passion and commitment to delivering technological innovation come to be inspired. I look forward to seeing you there.
