  • Assessment of domestic consumption in intermittent water supply networks: case study of Puerto Ayora (Galápagos Islands)

    Intermittent water distribution systems are a stark reality in developing countries. Puerto Ayora, the centre of tourism of the Galápagos Archipelago, is not an exception, with its population and tourists suffering from scarce water resources. However, the extreme per capita consumptions, well above those in 24/7 supply situations in many other countries, contradict the (sense of) scarcity. In ...

  • Sound recording to characterize outdoor tap water use events

    Obtaining disaggregated water use at the home typically involves expensive smart metering. In this study, water use events at the outdoor tap were captured using recorded sound. Outdoor taps at 10 homes were fitted with small-sized microphones and digital sound recorders. Sound files recorded over a 1-month period were used in the analysis. In the preliminary analysis, a human operator browsed ...

  • Water budget analysis and management for Bangkok Metropolis, Thailand

    The water budget of the Bangkok Metropolis system was analyzed using a material flow analysis model. Total imported flows into the system were 80,080 million m3 per year (Mm3 y–1) including inflows from the Chao Phraya and Mae Klong rivers and rainwater. Total exported flows out of the system were 78,528 Mm3 y–1 including outflow into the lower Chao ...

  • 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 ...

  • Statistical assessment of water quality of a Ramsar site wetland

    This study was conducted to evaluate the wetland water quality (WWQ) over a period of 3 years and establish relationships between these qualities using Ramsar site Uchali Wetland, Pakistan (32 °33′N, 72 °01′E). WWQ data obtained were subjected to summary statistics, generalized linear model (glm), correlation, covariance and cluster analysis. The glm of the monthly mean water indices showed ...

  • 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 ...
