Settle in to your favorite chair, get comfortable, and start turning the pages of this issue to traverse the globe and learn about the world of water. From the qanats of the Sahara to the gold-rush-inspired water systems of Australia, this month's articles provide a panoramic view into such issues as water delivery, management techniques, innovation, wastewater treatment, and wastewater operator training along the US-Mexico border. Let's start in Algeria where Remini and Achour (page 104) take us on a journey through a type of ancient system of water delivery first developed in Iran more than 3,000 years ago. Although dated, the qanat-an underground system of hand-dug tunnels that deliver water-continues to bring water to arid regions today. Highlighting a specific area in Algeria known as the Greatest Western Erg (or sand sea), the authors explain how a slight modification to this type of hydraulic technology could help to keep water flowing to oasis towns in this region.
