With another dry year setting in across the West, the challenges of meeting the water supply needs of a growing population while maintaining our rural communities and a healthy environment are again being thrown in sharp relief. The continuing decline of Lake Mead has become a symbol of deepening problems, but there are also less-noticed examples of success – in conserving water and sharing in times of scarcity – which we need to understand in order to craft solutions.
Scarce Water Resources and Development of Appropriate Decentralized Technologies for Sustainable Water Supply in the Negev Desert

Water scarcity has been the driving force for Israel’s search for ‘new water resources.” The use of marginal water has grown significantly over the past 20 years (more than 80 percent reuse of wastewater nationally). The main sources of marginal water in the Negev Desert in Israel are: Geothermal brackish water, recycled wastewater and graywater. Current use of these waters includes: Irrigation of a variety of agricultural crops, brackish-water aquaculture, landscape irrigation, recreation parks and tourism. Although marginal waters seem like a promising resource, their use has quite a few mid- and long-term negative effects. These include: Negative environmental effects on soils and plants, possible contamination of groundwater, and health risks. In addition, reuse treatments should be decentralized and kept low-cost to benefit sparsely populated areas, small remote villages and farms. Continuous research efforts are currently conducted to utilize marginal waters and sludge efficiently in a way that will maximize the outcome of its use with minimal negative environmental effects. Prof. Amit Gross will present an overview of several such studies with respect to the status of Israeli water resources.
Brown Bag Seminar - How myths and misinformation stand in the way of solving our water problems
Brown Bag Seminar - Salt River Project and HydroLogics
HydroLogics uses water resources modeling tools to facilitate planning, operations, and conflict resolution on the scale of single-reservoir systems all the way up to large multi-state river basins. The conjunctive management of surface and groundwater resources at SRP has historically created a very reliable and sustainable supply of water for SRP's shareholders and customers.
WRRC Conference 2018 - The Business of Water
Water is everyone’s business and the business of water affects everyone. On Wednesday, March 28, 2018, The Business of Water will be front and center at the University of Arizona (UA) Water Resources Research Center’s Annual Conference, which will be held at the University of Arizona Student Union in Tucson, Arizona.
