With a brief description of the physical setting and institutional history of the Australian water sector, this paper reviews the water institutional reforms in Australia focusing especially on the nature and extent of reforms initiated since 1995 and provides a few case studies to highlight the issues and challenges in effecting changes in some key reform components. The reforms initiated in 1995 are notable for their comprehensiveness, fiscal incentives and clear and time-bound targets to be achieved. Although water institutions in Australia have undergone remarkable changes, thanks to the reforms, there are still issues and challenges inherent in reforming maturing water institutions. Regional diversity in legal systems and quality standards as well as conflicts between private interest and public welfare are still serious to constraining market-based water allocation and management. While Australia still needs further reforms, its recent reform experience provides considerable insights into the understanding of both the theory and the practice of water institutional reforms.
Worst Water Weeds #1: Hydrilla
The Center for Invasive Species and Ecosystem Health lists a total of 79 different invasive and exotic aquatic plants that can be found in various parts of the United States. Some are wreaking more havoc than others, but one of the worst of all is hydrilla. It has invaded across much of the southern United States, and is beginning to make its way northward. Below are the basics of this invasive exotic water weed that the USDA Forest Service calls “…one of the most troublesome aquatic plants in the...
Closer Look at the Capacity of SLA Batteries and Solar Energy Systems
Sealed lead acid (SLA) batteries have a reputation for being durable when used to support portable electronic devices. They require minimal maintenance and offer leak-proof capabilities. But when used with solar energy systems, the units present issues that can hinder the potential and performance of the machines. For example, general purpose SLA batteries should not be deep cycled, as continuously discharging below 50-70 percent of its rated capacity could damage the units. In application, this would mean that...

Case study - Well monitoring for a water supplier
The municipality company, in city of Luebek, Germany, provides potable water for approximately 120,000 households, all pumped from more than 30 wells. These wells have water levels as deep as 160 meters. The water levels of these groundwater wells must be measured with the highest possible accuracy. Previously, the pressure probe`s analogue output signals (4…20mA) that had been used did not fulfill the required specifications and were replaced with OTT systems in 2014. The OTT Pressure Level Sensor was...
5 ways to conserve water this winter
Water conservation is something we harp on during the summertime, but what about during the winter? When the irrigation systems shut down, it’s easy toput conservation on the back burner while indoor water waste continues to occur. According to the U.S. Geological Survey, the average person uses 80-100 gallons per day for everything from cooking, to showering and flushing the toilet. While there are a number of ways to integrate water conservation into your daily routine, here are five tips that will...
