  • 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 ...

  • 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, ...

  • Residential spill in VA

    Laboratory analysis of soil samples showed high values of TPH/DRO showing an initial value of 18,800 and 8,300 ppm and the samples of soil analyzed after treatment with VaporRemed showed a value of 290 ppm and 210 ppm. Both these values are below the stipulated 500 ppm of TPH/DRO. The TPH in the drain water after flushing with the product showed values below the detection levels. The project was ...

  • 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 ...

  • Understanding urban residential end uses of water

    The ‘end use’ of water is a breakdown of the total household water usage such as water used for toilets, showers, washing machines, taps, lawn watering, etc. Understanding end uses of water will enable water planners, water authorities and household owners determine where water is used/wasted, how much and how often. This paper describes the end uses of water from a number of single-family homes ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Micro-component survey of residential water consumption in Hanoi

    Daily total water consumption per capita has been used as a basic unit for the future planning of water supply for domestic use. However, for innovative water utilization designs that consider various scenarios, including the effects of policy direction and global warming, and more strategic and efficient water use, it is absolutely essential to consider water usage divided by residential ...

  • 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 ...

  • 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 ...

  • Evaluation of statistical sampling for the assessment of residential consumption totals in water distribution networks

    The paper provides insights into stratified sampling, a standard statistical technique that may be employed to assess domestic water use in water distribution networks. The basic idea is to use only a few meters to provide inference on the total water consumption of a network or of a district metered area through the knowledge of some additional stratification variables, such as household ...

  • Using smart meters to identify social and technological impacts on residential water consumption

    Studies have shown that householders' perceptions of their water use are often not well matched with their actual water use. There has been less research, however, investigating whether this bias is related to specific types of end use and/or specific types of socio-demographic and socio-demographic household profiles. A high resolution smart metering study producing a detailed end use event ...

  • Examining the effectiveness of residential water demand-side management policies in Israel

    Increasing global water shortage is enhancing the need for water management policies, such as water demand policies. This study presents the main water demand-side management policies implemented in Israel, designed to reduce water demand in the urban sector, and subsequently examines their effectiveness by an econometric model, based on residential water consumption data. The main findings ...

  • 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, ...

  • Residential water treatment - the next big class action litigation

    TTHM, MTBE, and Perchlorate. Mention these potential water contaminants around municipal water and wastewater supervisors, the Department of Defense, or the major U.S. oil producers, and see how fast the room clears! The major oil companies are back in litigation after the failure of current treatment technologies to remove MTBE contamination in residential drinking water supplies, the Department ...

  • Biowaste collection in residential areas with dense population

    Because of legal regulations in Germany the biological treatment of organic residues is becoming more and more important. Following the regulations of the Waste Avoidance, Recycling and Disposal Act (KrW-/AbfG) and the TASi (Technical Data Sheet of Urban Wastes) biowaste has to be collected and treated separately. The waste management objective of the separate collection and biological treatment ...
