  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • Development of a model for activated sludge aeration systems: linking air supply, distribution, and demand

    During the design of a water resource recovery facility, it is becoming industry practice to use simulation software to assist with process design. Aeration is one of the key components of the activated sludge process, and is one of the most important aspects of modelling wastewater treatment systems. However, aeration systems are typically not modelled in detail in most wastewater treatment ...

  • Hybrid genetic algorithm in the optimization of energy costs in water supply networks

    Efficient operation of water distribution systems is linked with the assurance of water availability to the population. In general, the operational rules applied to water distribution networks have as a sole objective the continuity of the water supply and disregards saving energy costs related to the operation of the pumps. The task of determining optimal operational procedures involves several ...

  • Integrating water distribution system efficiency into the water conservation strategy for California: a Los Angeles perspective

    Improving water management in California requires a transition from imported to local water resources used efficiently. To assess this transitional capacity of water retailers in metropolitan Los Angeles County, we focused on a key water management metric: the water distribution efficiency. We traced the evolution of water loss reduction policy and practices globally with emphasis on ...

  • A simulation tool for life cycle costing of water supply infrastructure in seismically active zones

    In the face of increased development, civil infrastructure systems are increasingly vulnerable to catastrophic failures as a result of ageing, overuse and poor planning when disasters such as earthquakes strike. Water supply systems are among the most vulnerable infrastructure systems and arguably, the most essential for human existence. Investment decisions regarding the retrofitting or ...

  • Getting Started with Distributed Data Logging

    In the first part of this series, I talked about how I see distributed data logging as an evolving trend in the field of general purpose data logging. I discussed what it is, the parts that make up distributed data logging systems, and some of the technology for connecting and communicating between the different pieces of the ...

  • What are Distributed States and When are they Important? New Strategies to Improve EBPR Performance

    ABSTRACTComputer simulation of activated sludge processes is a critical tool for design, operation, and troubleshooting, but simulating enhanced biological phosphorus removal (EBPR) systems has proven to be particularly challenging. This may be due in part to uncertainties in biokinetic models, but new research suggests it may also be due to deficiencies in conventional “lumped state” approaches ...

  • Rold Model Water Recycling Program

    ABSTRACTThe Viejas Band of Kumeyaay Indians, a federally recognized tribe, vested with authority by the U.S. Environmental Protection Agency (USEPA), form the Tribal Government to regulate all activities concerning water quality issues within the reservation boundaries. The Reservation has 400 non-transient residents and an average of 5,000 transient residents. The transient population visits the ...

  • An integrated energy, carbon, water, and economic analysis of reclaimed water use in urban settings: a case study of Austin, Texas

    As water supplies become strained, some municipalities have turned to reclaimed water as a potential source to meet non-potable needs. Such reclaimed water – wastewater effluent treated to appropriate quality standards – is not suitable for human consumption without additional treatment, but can be used for purposes such as irrigation and cooling. One reclaimed water distribution system of ...

  • A comparison between different techniques for water network sectorization

    Water network partitioning represents one of the best methodologies for improving water balance and pressure control of a water distribution system in order to reduce water leakage. These techniques can be applied with greater effectiveness defining a smaller permanent network district, called a District Meter Area (DMA), achieved by the insertion of gate valves and flow meters. If the DMAs are ...

  • Anglian water Cryptosoridium outbreak - Case Study

    Pitsford Drinking Water Site, England In June 2008, a rabbit was located in the wash water tank at the Pitsford Drinking Water Plant of Anglian Water, leading to contamination of the treatment works with Cryptosporidum, a chlorine resistant parasitic micro-organism. The parasite was detected on June 24 and, following consultation with health and local authorities, a notice to boil ...

  • On the weaknesses and limitations of EPANET as regards energy

    With more than 1,500 citations in ranked journals and hundreds of thousands of downloads, EPANET is the benchmark software for analysis and design of pressurized water distribution networks. User-friendly, powerful and reliable, its public domain use has spread throughout the world. However, from an energy standpoint its capacity is limited to the point at which, in certain circumstances it ...

  • Flexible data management helps in regulatory compliance, by Colin Thurston, director of product strategy, process industries, thermo fisher scientific

    In the US state of Florida, the public regional wholesale water provider Tampa Bay Water and Veolia Water North America completed a 454,000 cubic meters (120 million gallons per day) water treatment plant that exceeds federal and state drinking water quality standards. The design, build, and operate (DBO) approach helped to save US$80 million and kept the project on schedule.The Tampa Bay Water ...

  • Pulsar`s Blackbox 136 Level CSO Controller provides an immediate view of sewage overflow events in Ljubljana, Slovenia

    Slovenia's largest water distribution and waste water disposal company, Javno podjetje Vodovod-Kanalizacija d.o.o. Ljubljana, invited Pulsar distributor, MIMOS, to help gather information of sewage overflow events along local rivers. By using a combination of MIMOS software, ...

  • Effective fight against unpleasant smell

    As part of a project for the neutralisation of hydrogen sulphide in the sewage system of a medium-size municipality, sera has started over ten innovative dosing systems in September 2008. An effective solution was developed in cooperation with an internationally operating water technology company. A municipality of approximately 50.000 citizens in the German state of North Rhine Westphalia was ...

  • The future of leak detection starts today

    For many water engineers the day in the office begins with a look at the screen. They can analyse the results of the nightly measurements of their fresh water pipelines in a few minutes and make important decisions for the day. Are there any new leaks in the system? Using the information found, the water engineer can send his workers to precisely those points that the leak detection system has ...

  • UV set to dominate the municipal industry

    The use of Ultra Violet (UV) light has now become standard practice in most municipal waste water treatment processes. Effluent is now starting to be recognised as a valuable resource, not a problem that needs to be dumped.  Many waste water facilities are being renamed as water reclamation facilities, and whether the waste water is being discharged into a river, being used to irrigate ...
