  • Crumbling Concrete Water Networks Linked to Common Water Treatment Additive

    Concrete distribution and sewer networks are being corroded at an alarming rate partly because of a commonly used additive in the domestic drinking water and wastewater treatment process according to published reports in the journal Science. In countries throughout the world from industrialized nations like Australia and the USA to developing nations like Colombia, Ghana and the Philippines, the ...

  • Get more out of Water Resources Engineering Models

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public. This approach might serve ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • Optimizing Wind and Solar Power in Africa

    Editor's Note: The following is a news release authored by Julie Chao and issued by Lawrence Berkeley National Laboratory on April 5, 2017 To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence ...

  • Understanding the True Cost of Water

    Overcoming Barriers to Corporate Water Stewardship For companies pursuing corporate water stewardship strategies, a common barrier to action is the perceived low cost of water “at the tap.” Water reduction, reuse, and recycling projects often do not meet investment hurdle rates or compare positively to other investments. This also acts to limit community and watershed ...

  • Sinking Costs

    Today there is more pressure than ever for businesses to minimize costs and increase productivity. Companies are always looking for ways to reduce overall costs. Unfortunately, these efforts are often hampered when a company is faced with an environmental investigation. Regulatory agency requirements, such as determining the full horizontal and vertical extent of contamination in soil and/or ...


  • Decrease Operating Costs with Water Recycling

    Compliments to the growing competition from NAFTA, tighter environmental regulations, and increasing demand for higher quality finished products, the profits for Fresh Cut Food processors has decreased over the years. Profits canbe as low as a few cents per pound of finished product. Plant managers and engineers are scrambling to find methods of decreasing the processing operating costs and still ...

  • Impact of water volume on operating cost

    Sustainable water management relies on the ability to control operating cost which relies in turn on a working knowledge of factors which can affect this ability. The impact of water volume on operating cost is investigated for water utilities using data from the International Benchmarking Network for Water and Sanitation Utilities (IBNET) online database. Econometric models are estimated for ...

  • Review and evaluation of desalination cost and costing methodologies

    Recently, desalination is becoming a viable alternative for supplying potable water due to new developments in desalination technologies. At present, the cost of desalinated water is about US$0.5/m³ by RO and US$ 1.0/m³ by thermal processes. But these costs are location dependent. Thus the selection of an appropriate desalination technology for any location needs a reliable and accurate costing ...

  • Estimated Costs to Utilities for Issuing A Boil Water Advisory

    The United States Safe Drinking Water Act (SDWA) has stringent standards in place to ensure the safe distribution of water. However, water quality problems (e.g. water main breaks, elevated turbidity, microbiological non-compliance, etc.) can result in these standards not being met. The consequence of this is often a boil water advisory to inform the public that the water is unsafe to drink. ...

  • Nanofiltration technology in water treatment and reuse: applications and costs

    Nanofiltration (NF) is a relatively recent development in membrane technology with characteristics that fall between ultrafiltration and reverse osmosis (RO). While RO membranes dominate the seawater desalination industry, NF is employed in a variety of water and wastewater treatment and industrial applications for the selective removal of ions and organic substances, as well as certain niche ...

  • The energy cost of water independence: the case of Singapore

    Finding alternative resources to secure or increase water availability is a key issue in most urban areas. This makes the research of alternative and local water resources of increasing importance. In the context of political tension with its main water provider (Malaysia), Singapore has been implementing a comprehensive water policy for some decades, which relies on water demand management and ...

  • Assessment of cost recovery through water pricing

    Setting the scene The environmental resources situation is shaped by changes in climatic conditions, coupled with pressures exerted by a rapidly growing global population, its increasing demands and the subsequent impacts on the environment. Current practices across the economy sectors are still not sufficiently ambitious in terms of sustainability; they fail to ameliorate the stress ...

  • Cost-Effective Control of Interdependent Water Pollutants

    Abstract  Excess nutrient loads to coastal waters lead to increased production of algae, which when decaying cause oxygen depletion in bottom sediments, which in turn leads to major changes in marine ecosystems. A cost-minimization model was investigated in which nitrogen and phosphorus were assumed to interact with respect to algae production. It was investigated under what conditions only ...
