  • Hydrochemical and multivariate analysis of groundwater quality in the northwest of Sinai, Egypt

    The northwestern coast of Sinai is home to many economic activities and development programs, thus evaluation of the potentiality and vulnerability of water resources is important. The present work has been conducted on the groundwater resources of this area for describing the major features of groundwater quality and the principal factors that control salinity evolution. The major ionic ...

  • How important are water, snow and ice layers for the friction?

    A recent research project of the Technical University of Berlin (TU Berlin) aimed to develop a method for predicting the friction coefficient on the road. To achieve this, the team of the university’s automotive engineering section carried out extensive braking tests. For this, an important technical aid from Lufft mustn’t be left ...

  • Variability of water residence time and free chlorine and disinfection by-product concentrations within a residential neighborhood

    Sampling campaigns at several points in a sector of a distribution network were conducted during several months to study the spatial and temporal variation of the free chlorine concentration (FCC) and disinfection by-product concentrations (DBPC) at the scale of a residential neighborhood. The water residence times (RT) at these sampling points and for the same period were also simulated using ...

  • Systematic risk management approach of household drinking water from the source to point of use

    The water safety plan (WSP) approach is being widely adopted as a systematic approach to improving the safety of drinking water. However, to date, the approach has not been widely used for improving the safety of drinking water in those settings where people have to collect water away from their home. Most rural areas in South Africa still consume unsafe water despite WSP implementation and ...

  • Developing a Culture of “Revulsion”: Singapore Tackles Water Wastage

    Singapore is an interesting place. As a city-state it occupies a very small amount of land area, about 700 square kilometers. Packed into this space are 5.6 million people working in one of the world’s strongest economies. A big part of the economy is based on manufacturing and oil refining. Both of these sectors are intensive water users. Because of this, water availability is a big issue. ...

  • 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 to put 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 ...

  • Reducing the burden of rural water supply through greywater reuse: a case study from northern Malawi

    Greywater reuse has potential for non-potable applications that conserve freshwater resources in water-stressed areas especially in sub-Saharan Africa. The feasibility of reusing greywater for domestic activities in a rural area of Malawi, Africa, was evaluated from microbiological and public acceptance perspectives. Median Escherichia coli concentrations for eight domestic greywater sources ...

  • Biological monitoring system, iTOXcontrol, continues in Scarlino - Case Study

    The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these ...

  • Ten Ways to Conserve Water This Holiday Season

    The holiday season is almost here, which to us at WaterSignal means even more opportunities to conserve water! As you gear up for the holidays, save water and money with these ten water saving tips: 1.) Buy recycled paper products: Products made from 100 percent recycled paper require much less water in their manufacturing than those made from virgin paper. 2.) Inspect bathroom ...

  • Anglian Water selects Proam ammonia monitor

    Anglian Water (AWS) has selected the Proam ammonia monitor to provide continuous ammonia measurement on final effluent discharge where accurate and reliable measurement is required. One of the most recent installations is at Stanningfield WwTW situated near Bury St. Edmunds, in Suffolk. This is a small rural site receiving primarily domestic sewage. The site performs aerobic ...

  • A water balance approach for assessing the potential source of water in Dohuk Dam for agricultural, domestic and tourism purposes

    Water balance approaches have been widely used to stimulate and forecast the average runoff and river discharge in small- and medium-sized basins. The analysis of water balance for Feesh Khabour River and Dohuk Dam catchment areas needs to be verified. This study used 24 alternative scenarios for assessing the robustness of adaptation decisions to water management practices. The discharge of ...

  • Study of hydraulics and mixing in roof tanks used in intermittent water supply

    Roof tanks are common in low and middle income countries, due to the intermittent water supply. Their hydraulic and water mixing behaviour has not been studied. This paper presents the results of a study on mixing and water demand in roof tanks, based on physical and numerical models. Tracer tests were carried out on a real scale transparent wall laboratory model of a roof tank, and a ...

  • Exploring the effects of domestic water management measures to water conservation attitudes using agent based modelling

    The urban water system's sustainable evolution requires managing both water supply and water demand within a complete urban water cycle framework. Such an approach, however, requires tools to analyse and simulate the complete system including both physical and cultural environments. One of the main challenges, in this regard, is the design and development of tools able to simulate the ...

  • PAHs in Parking Lot Sealcoats - Case Study

    There is growing concern - and regulations in the works - over the use of sealcoating products due to their high PAH content.  In the United States and elsewhere, most sealcoats are made from coal tar which can be toxic to aquatic life and threaten public water supplies from rain and runoff.  Sample was collected from a freshly treated parking lot in Seabrook, New Hampshire. The ...

  • A stochastic model for daily residential water demand

    Residential water demand is a random variable which influences greatly the performance of municipal water distribution systems (WDSs). The water request at network nodes reflects the behavior of the residential users, and a proper characterization of their water use habits is vital for the hydraulic system modeling. This study presents a stochastic approach for the characterization of the ...

  • Does the risk of Legionnaire’s Disease rise when there’s lead in your water?

    Ongoing monitoring shows that lead levels in Flint, Michigan’s water are dropping and getting closer to meeting federal safety standards. That’s some much-needed positive news for the community. But there’s still work to be done. Now, researchers are starting to check residential hot water heaters in Flint homes for Legionella. Legionella grows best in warm water and hot water ...

  • A case study of the conversion of grey water to a flush water source in a Turkish student residence hall

    A case study of the conversion to grey water to a flush water source in a student residence hall of the Turkish megacity Istanbul is presented. Grey water from bathtubs/showers and washbasins is treated and reused for flushing toilets. Raw and membrane bio-reactor (MBR) treated grey water quality was monitored throughout one academic year using parameters to characterize organic matter ...

  • Occurrence of toxic cyanobacteria and microcystin toxin in domestic water storage reservoirs, Egypt

    Residents in many developing countries store treated drinking water in tanks or reservoirs because of intermittent and infrequent water supplies. Many studies have focused on bacterial contamination of domestic reservoir waters, the cyanobacterial and algal contamination is largely unexplored. Therefore, the present study investigates toxic cyanobacteria and their microcystin (MC) toxins in ...
