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.
Robust systems for optimal treatment - Case Study
Big Park Domestic Wastewater Improvement District in Arizona had constructed a new 500,000 gallons per day biological wastewater treatment system in 1997. As time passed, the aging plant was unable to keep up with increasing demands.ChallengesIn 2012, the District started working with Sunrise Engineering to find a solution that would work in their existing plant. Sunrise Engineering partnered with Aeration Industries International to upgrade the equalization basin, as well as the sludge digester/thickener.SolutionI...
Reasons You Should Invest in an Arsenic Water Treatment System
In many areas of the U.S., the element arsenic makes its way into the water supply. This element can have adverse health effects. Although it’s rare that it shows up in large enough concentrations to be fatal, it can still cause problems and should be eliminated. Health Effects Many studies have been done to determine the specific effects of consuming water tainted by arsenic. One of the most common health ailments is lesions. Regularly consuming water with traces of arsenic can cause skin problems. This...
5 Reasons to Use Eductor Systems for Complex Rehabilitation
Rehabilitation of dams and levees present complex geotechnical conditions. Contractors require dry, safe and stable working environments in order to carry out an effective rehabilitation project. As our national dam and levee infrastructure ages, the pressure to stabilize construction sites and lower costs will rise. Eductor systems provide a safe, cost-effective dewatering solution for these high-risk projects. First, a series of eductor wells are drilled and connected to a common header. High pressure water...
Meeting Water Needs With Desalination
As demand for fresh water increases, communities look to the sea and to previously unusable aquifers With the world’s population consuming water in record amounts and water scarcity causing a host of geopolitical and humanitarian problems, technology can be harnessed to help meet the demand. One increasingly important solution to freshwater scarcity is treating saline water through a process known as desalination, or desalinization. Many areas already are turning to desalination to stave off shortages of...
How to Choose the Right Biological Water Filtration System
There are many different biological treatments of water available. They’re all similar in a number of ways, but share key differences in the specific ways the water is filtered. This article is an informative breakdown of all the different biological water treatment systems that are available and how they work. Slow Sand Filtration This system supports the growth and maintenance of microorganisms that eventually become its primary filtering mechanism. Its layers work to get rid of any potential contaminants...
