2019 has been a successful year for Water Supply. We have witnessed improvements on all fronts – increases in the number and quality of submissions, growth in our Impact Factor, with an increase in Open Access papers, and a faster turnaround of manuscripts. We have been making continuous efforts to improve not only the speed of peer-review but also the thoroughness and fairness of this process, which can only be achieved through a balanced and well-informed and qualified assessment of papers. As always, the reviewers’ generously volunteered time is to be acknowledged – their expertise is absolutely essential for the production of scientific journals. I would like to thank all those who reviewed Water Supply manuscripts this year and I hope that they found this experience intellectually rewarding and would be prepared to support us in the future. My gratitude also goes to authors of all the papers we published this year and to members of the Editorial Board who worked hard to meet our targets.

In order to recognise the quality of research presented in the journal, we are introducing an annual Best Paper Award. It was not an easy task to select the highest quality contributions from over two hundred papers we published last year. A shortlist of outstanding papers was formed following the Editors’ recommendations and marks, and these were assessed with regard to scientific excellence, relevance to practice, and overall presentation. Congratulations for the Inaugural Best Paper Award goes to Sandis Dejus, Alīna Neščerecka, Ģirts Kurcalts and Tălis Juhna from Riga Technical University in Latvia, for their contribution entitled ‘Detection of drinking water contamination event with Mahalanobis distance method, using on-line monitoring sensors and manual measurement data’. This paper – published in 2018 Volume 18 Issue 6 of Water Supply – introduced a seemingly simple yet novel and elegant method. Its practical applicability was nicely demonstrated and performance evaluated using real-world data, with clearly argued conclusions. The paper is freely available to download at the journal website.

We look forward to receiving top quality manuscripts and furthering knowledge in all aspects of water supply through our forthcoming issues.
