  • 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 ...

  • 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 ...

  • 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 ...

  • 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, ...

  • 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 ...

  • Analysis of domestic water demand variables of a residential colony in Ajmer, Rajasthan (India)

    In this paper, significant variables of domestic urban water demand required for the purpose of estimation of urban water supply in five planned colonies of the City of Ajmer, Rajasthan, India, are identified. The data for these 16 variables are entered in the multiple linear regression (MLR) (stepwise) models in SPSS software, and domestic water demand models are developed. Based on these ...

  • Pearl river valley water supply district case study

    Performance History and Discussion In-Pipe Technology implemented the first phase of a collection system Professional Services Program in 2001. Beginning in 2002, additional collection system basins were added to the services program. Currently, the treated areas include the North and South shore of the Pelahatchie Bay, the Main Harbor, and two Lagoon Waste Water Treatment Plant (WWTP) ...

  • Water rate to manage residential water demand with seasonality: peak-load pricing and increasing block rates approach

    A strong seasonal demand for water occurs in many tourist areas, which might exacerbate the water shortage problems. Water pricing is a key instrument for water use management; therefore, the objective of this work was to design a variable water rate to examine the seasonal water demand in water-scarce regions. The proposed water rate combines the peak-load pricing (PLP) and increasing block ...

  • Quantitative assessment of residential water end uses and greywater generation in the City of Al Ain

    Diversification of water sources and water demand reduction are two vital tools in maintaining the security of urban water supplies in the United Arab Emirates (UAE). Reuse of greywater for non-potable end uses can be an effective alternative, but this resource has not yet received much attention in the UAE. Since the generation of greywater significantly differs from country to country – ...

  • Assessing the impact of property size on residential water use for selected neighbourhoods in Lilongwe, Malawi

    Malawi has one of the highest urbanisation rates in Africa, with an urban housing approach that favours large residential plot sizes. The impact of plot size on residential water use was evaluated by examining water use records, obtained for the period between January 2009 and December 2014, for formal residential properties in the city of Lilongwe. Water use increased with plot size in line ...

  • Development of residential water demand model for a densely populated area of Jaipur City, India

    Water demand forecasting has become an essential ingredient in effective water resource planning and management. In water-scare urban areas of developing countries, this emphasis on accurate forecasting is particularly important for effective water resource planning and management. This paper presents an econometric water demand model for forecasting future residential water requirements for a ...

  • How supply system design can reduce the energy footprint of rainwater supply in urban areas in Australia

    In Australia rainwater tanks are used in cities to reduce demand of mains water and increase the resilience of cities to drought. Rainwater is collected in a tank and supplied to a dwelling through a small pump. Typically the energy footprint for rainwater supply (in kWh/kL) is higher than for centralised water supply, but it can also vary markedly from dwelling to dwelling (0.4–11 ...

  • Decentralized Water Reuse

    Water is an integral part of our society today. This vital resource is used in the operations of many industrial processes, human consumption, and for food production to name just a few. The increasing demands for water for agricultural, drinking and industrial processes has put significant strain on global fresh water supplies as the world's population continues to grow. In many parts of the ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Water balance modelling of alternate water sources at the household scale

    Alternate water sources are being implemented in urban areas to augment scheme water supplied by a water utility to homes. These sources include residential wells, rainwater tanks and greywater systems. Greater water efficiency can be achieved when these systems are designed to match a water source to a given demand based on both water quantity and quality parameters. In this way the use of an ...

  • Case study - Halifax Water

    A section of the 30" diameter LCP Halifax-Bedford connector pipeline was identified by the client as being high-risk as it operated at a relatively high pressure (over 170psi), supplied a rapidly growing community and ran past residential areas along side of a highway. It would have been difficult to remove the line from service so Halifax Water selected PipeDiver to carry out a condition ...
