About LET

Water-technology innovations for emerging challenges

As head of the local organizer committee is my pleasure to invite you to the 16th IWA Leading Edge Conference on Water and Wastewater Treatment 2019 that will take place in the beautiful city of Edinburgh, in Scotland in the United Kingdom.

The UK water Industry market is one of opportunities. There are many issues that need to be addressed, such as: ageing infrastructure; compliance with ever stringent regulation; fast growth of urban centres and need to develop sustainable solutions for rural communities; energy and carbon prices; reduction of quality of water sources; variable weather patterns leading to severe draughts and floods; the need to engage with local communities and governments promoting circular economy; etc. are forcing water professionals to think creatively and move innovation to full-scale implementation at an unprecedented rate. The key to the success of the LET conference series, and very strong reputation, is the excellent scientific programme that has a perfect blend of academic research and implementation of novel technologies. The LET2019 will attract key water professionals and stakeholders from the UK and around the world to delivery an inspiring programme and a memorable conference.

Cranfield University, the lead LET2019 organiser, has partnered with two key water utilities in the UK. Scottish Water is the publicly owned utility providing water and wastewater services to 2.5 million households and 156,000 businesses and Thames Water, the UK’s largest water and wastewater services provider.

Edinburgh is one of Europe’s most beautiful cities, surrounded by rocky hills overlooking the sea, renowned for its heritage, culture and festivals. With walking distance you can visit and explore World Heritage Sites, as well as all the area’s museums and galleries. On behalf of the local organizing committee it is a pleasure to welcome you in Edinburgh in June 2019.

This is the 16th year of the LET and it has grown to be an important forum for presenting and discussing the most significant global technology developments in water. New critical water technology developments are emerging continuously and it’s important to be aware of these. Every year the committee attempts to focus on the issues that are receiving globally and regionally the most attention. Bringing innovations, novel technology developments, and leading edge applications from across the industry is key to this conference. Each session is developed to create a cohesive and interesting discussion. This is accomplished by inviting some of the most impactful water technology leaders in the industry On behalf of the Program Committee, we strongly encourage you to actively participate in this conference through the submission of your papers on innovative and sustainable technology approaches. We hope to again attract exciting and novel contributions that have made the LET conferences such a high level event in the past decade. The success of this conference will largely depend on your participation, so please join us in Edinburgh in 2019. We are confident we will have a stimulating and invigorating exchange on all these ideas and solutions you have come up with.
