residential water system Articles

  • Residential system design

    Rainwater systems can be as simple as placing a rain barrel beneath a downspout or they can be complex – engineered multi-tank systems with pumping stations and automated computer controls for supplying commercial and industrial process applications. Consider that in one installation in the Sumo arena in Japan, rainwater is supplied for flushing toilets and the cistern’s excess ...

  • 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 ...

  • Price elasticity of residential water demand in California

    This study used meta-analysis to assess the influence of price/price structures on residential water demand in two selected urban areas in California: East Los Angeles and South San Francisco. Monthly usage data for the years 2002–2011 were utilized to determine and compare price elasticities for periods when uniform and tiered rates were charged using fixed effects panel regression and ...

  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...

  • Estimating residential water demand in the absence of volumetric water pricing

    Rapid population growth has significantly increased the magnitude of water shortages in California. Although water shortages already exist, some of the state's utility systems are still not providing their residents with financial incentives for water conservation. Instead of using water meters to charge households according to their actual water usage, they are charging a flat fee for unlimited ...

  • Analysing the dynamics of transitions in residential water consumption in the Netherlands

    Water infrastructure is inherently a socio-technical system. Rapidly changing urban trends and long-term uncertainties make water infrastructure management complex. This paper analyses the dynamics of residential water consumption in the Netherlands since 1900. During this period, different drivers for change had an influence on residential water use. Results show that different (f)actors and ...

  • Understanding residential rainwater harvesting

    We use the phrases rainwater harvesting, rainwater utilization, and rainwater collection to describe the process of collecting and using rainwater as an alternative or supplemental water source.  Rainwater harvesting is typically restricted to non-potable (Not for Drinking) applications like: landscape irrigation, vehicle washing, toilet flushing, laundry, cleaning and custodial services, ...

  • ThyssenKrupp Residential, Germany - case study

    Overview ThyssenKrupp, a German industry leader in residential property management, managed 48,000 apartments and had a market worth of $2.9 billion Euro when it was sold in late 2004. Water System Challenges Originally, water was fed to every housing unit through pipes that were 30 to 40 years old. These pipes were corroded with significant rust and calcification ...

  • Impact of water source management practices in residential areas on sewer networks – a review

    Prolonged drought which has occurred everywhere around the world has caused water shortages, leading many countries to consider more sustainable practices, which are called source management practices (SMPs) to ensure water availability for the future. SMPs include the practices of water use reduction, potable water substitution and wastewater volume reduction such as water demand management, ...

  • Characteristics of small residential and commercial water systems that influence their likelihood of being on drinking water advisories in rural British Columbia, Canada: a cross-sectional study using administrative data

    Health officials often lack information about characteristics that predict which water systems are most likely to be placed on and to persist on drinking water advisories (e.g. health warnings offering advice or information). This study uses data collected by the Interior Health Authority in British Columbia to characterize water systems on advisory for microbiological threats and to identify ...

  • Simulating residential indoor water demand by means of a probability based end-use model

    A probability based end-use model was constructed as part of this study to derive diurnal residential indoor water demand patterns on a temporal scale of 10 seconds. The end-use model derived the water demand patterns by aggregating the synthesised end-use events of six residential indoor end-uses of water in terms of the water volume required, duration and the time of occurrence of each event. ...

  • Redistributive impact of increasing block residential water rates: some empirical evidence from Mauritius

    This paper presents empirical results on progressive incidence of water charges that contradict conventional wisdom in developing and many developed countries. Family size in Mauritius is larger among high-income categories relative to low-income groups. Because of this unusual demographic dimension, increasing block tariffs coupled with lifeline rates below long-term marginal costs applicable to ...

    Garness Engineering Group, Ltd. (GEG) based out of Anchorage, Alaska was contracted by the Alaska Native Tribal Health Consortium (ANTHC) to provide engineering services associated with the design and installation of septic systems throughout their Southcentral region. In 2009, GEG was tasked with providing a septic system for one of ANTHC’s residential customers located in Glennallen, ...

  • Conventional and alternative water supply systems: a life cycle study

    Research on urban development to date has tended to focus on buildings and their performance in terms of associated energy and environmental impacts. Although, many detailed studies of residential buildings have been carried out, these studies usually concentrate on the house itself without consideration of the infrastructure systems. Alternatives to traditional infrastructure systems are ...

  • What water filtration system do I need?

    Water is abundantly available on the surface of the Earth. But do you know only 10% of the water is consumable, and the rest of the water is not usable? As the population is rapidly growing, the need for the consumable water is also growing. This increasing need for water has resulted in a scarcity of water in different regions. In such cases, the only solution is to reuse the ...
