[[Image:Water4iconsWater Portal.png|right|120px100px]][[Image:akvopedia logo.png|right|100px|link=http://akvopedia.org/wiki/Main_Page]]The water portal illustrates a selection of smart water technologies. We are working on making this portal comprehensive and contain full explanations on how to implement these technologies, complete with lots of reference manuals and links. In For help with selecting the meantime we hope the site can be right water technologies below, try our new [[Water Compass | Water Compass]]! It is a source of inspiration for those who are trying to improve access to clean waterdecision support tool.<br><br><br>To help manage drought, using water resource technologies and other strategies: [[Resilient WASH systems in drought-prone areas]].
