  • Assessing sustainability of community management of rural water systems in the developing world

    An alarmingly high percentage of drinking water systems in the developing world do not provide design service, or may even fail. This has health implications for vulnerable populations forced to consume water from alternative, often unimproved sources. The Sustainability Assessment Tool developed in this research serves as a diagnostic to inform decision-making, characterize specific needs of ...

  • Drinking Water Analysis Guide

    Public Water Systems (PWS), regulated by the United States Environmental Protection Agency (USEPA), provide drinking water to 90% of Americans. Water systems and laboratories testing drinking water for Safe Drinking Water Act (SDWA) compliance must be certified and must use USEPA approved methods, which are developed by the USEPA, other government agencies, universities, consensus method ...

  • Water testing 101: TDS

    According to Wikipedia, total dissolved solids (TDS) is defined as “the combined content of all inorganic and organic substances contained in a liquid that are present in a molecular, ionized or microgranular suspended form.” The article goes on to state that “total dissolved solids are differentiated from total suspended solids (TSS) in that the latter cannot pass through a ...

  • Chemical pollutants in water emerge

    Recent advances in contaminant identification methodologies, sampling instrumentation, and analytical chemistry have caused an explosion of knowledge about the presence of previously undetected organic micropollutants. While it doesn"t follow that the mere presence of chemical contaminants results in harm, public health experts, regulators, and others aren"t sitting idly by. Given the necessity ...

  • Pressure transfer modeling for an urban water supply system based on Pearson correlation analysis

    This paper presents an approach to modeling the water pressure transfer among nodes in an urban water supply network for the purpose of pressure control. The network is divided into different sub-networks based on the Pearson correlation analysis of the nodal pressure measurements. The Pearson correlation analysis is performed to find out the set of nodes, whose water pressures are highly ...

  • Policy recommendation for drinking water supply cross-border networking in the Adriatic region

    Cross-border water resources and drinking water supply management are among the basic concerns for almost all Adriatic Sea countries. Adopting measures such as developing common methodologies, tools and techniques addressing water quality and quantity issues, water losses and pricing policies is a top priority. Regarding the harmonization of procedures and legislative framework, the ...

  • 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 ...

  • Genetic algorithm-based optimization of water resources allocation under drought conditions

    The efficient allocation of increasingly scarce water resources is a growing challenge worldwide, particularly during times of drought. This paper describes the development and application of an innovative technique to optimize the allocation of raw water supply to the city of London, UK during a period of drought in 2006. Using genetic algorithms, an optimization tool was developed to derive ...

  • A simple forecast technique for estimating the statistical characteristics of water consumption

    The forecast water consumption values are the most critical input data in the pump schedule optimization of water distribution systems. The aim of this paper is to present a simple technique which is able to estimate the mean consumption and its distribution for a given demand zone with an hourly resolution. Simplicity (low computational cost) is advantageous since the forecast model needs to be ...
