INVITATION �+ on behalf of the Danish ministry of Foreign Affairs the Water Technology Alliance is proud to invite you on a Wastewater Fact Finding trip to Denmark in March 2017. 4 Jakob Andersen Danish Consul General WASTEWATER FACT FINDING TRIP TO DENMARK A unique opportunity to experience first-hand how Denmark is working to optimize wastewater treatment,energy efficiency,resource recovery and water quality. From March T.to March 9'the Danish Water Technology Alliances in Chicago and California is hosting a focused week long Fact Finding trip to Denmark for carefully selected US stakeholders.Apart from the airfare to Denmark the trip is paid for in full by the organizers. We are delighted to include you in a small group of carefully selected utilities and key stakeholders who areformally invited to participate in the trip. The Fact Finding trip will be an intense week long sleep dive into specific solutions and innovative projects.We have put together a tight packed program with a combination of on-site visits,visits to key innovators and projects showcasing what Denmark will implement tomorrow and the years ahead.As a participant you should expect lung days dedicated to professional discussions.In other words-this i's not a leisure trip,but an educational journey that hopefully will leave both you and the people you visit wiser and inspired to take action. You will be part of a small group of dedicated water professionals and we expect to dedicate a fall day of the program to share and discuss the challenges you are working with to ensure you not only get new knowledge and inspiration but also specific action points for implementation upon return to the US. r With consideration to the very limited number of available spots,the further planning of the trip and our ability to maximize the output for all participants we would greatly appreciate a committing RSVP from you no later than(and preferably before)February 15t 2017 to maland um.dk. �Ir r All participants will receive a fact finding program package a few weeks prior to departure. r We look forward to hear from you.

By having representatives from the leading Danish utilities spread the story about Denmark having had the same challenges that the American utilities are presently facing,there is a strong belief that the cooperation between the American utilities and the Danish eater Industry will blossom and gain advantages through the efforts made by WTA.

Thorough understanding of the invntved processes alimvs for their optimisation A better solution is to optimise the operation and processes of the existing WWTP through using on-tine sensors,data tanks.
