  • Times are changing: Wastewater as a resource

    Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like ...

  • Water quality management for domestic rainwater harvesting systems in Fiji

    Health risks from drinking rainwater are relatively small in the developing world context, but action is needed to ensure water safety. Water safety plans (WSPs) use an approach to manage water quality that has shown signs of success with public and communal water supplies, but relatively little research has been done to investigate the application of WSPs to self-supply systems. The aim of this ...

  • Domestic heating systems are more efficient with Scalewatcher

    In hard water areas plumbing, hot water systems and appliances quickly become encrusted with limescale resulting in increasing energy bills and the early renewal of boilers and appliances.  The award-winning, patented, Scalewatcher water-conditioner, from Scalewatcher North America, offers a simple and permanent solution to limescale thereby reducing energy bills and making heating systems ...

  • Taming the waters: strategies to domesticate the wicked problems of water resource management

    Increasing demands on water resource organisations are explored in three large US river basins: the Columbia River, Southern California, and the Potomac River Basin/Chesapeake Bay in the Washington DC metropolitan area. Interviews with staff of water management organisations revealed a strong preference for strategies that consolidate resources and over-build systems in order to provide reliable, ...

  • Applicability of domestic grey water reuse for alleviation of water crisis in Dhaka City

    Overdependency on ground water resources for meeting the daily water demand in Dhaka City is leading to excessive pressure on ground water aquifer systems and is deepening the ground water table every year. This paper focuses on how reuse of grey water generated from different sources of domestic purposes every day can alter the considerable daily water demand in this city. Sampling and ...

  • An analysis of domestic water management performance across regions in Taiwan

    This study presents an indicator to measure the performance of domestic water management that focuses on raw water consumption and sewage treatment by using the data envelopment analysis (DEA) technique. The data are extracted from twenty-two counties/cities in Taiwan covering the period of 2009–2011, and eventually sixty-six observations are obtained. We compare the management ...

  • Aggregation and biofilm formation of bacteria isolated from domestic drinking water

    The objective of this study was to investigate the autoaggregation, coaggregation and biofilm formation of four bacteria namely Sphingobium, Xenophilus, Methylobacterium and Rhodococcus isolated from drinking water. Auto and coaggregation studies were performed by both qualitative (DAPI staining) and semi-quantitative (visual coaggregation) ...

  • Designing domestic rainwater harvesting systems under different climatic regimes in Italy

    Nowadays domestic rainwater harvesting practices are recognized as effective tools to improve the sustainability of drainage systems within the urban environment, by contributing to limiting the demand for potable water and, at the same time, by mitigating the generation of storm water runoff at the source. The final objective of this paper is to define regression curves to size domestic ...

  • Performance evaluation of subsurface wastewater infiltration system in treating domestic sewage

    This study was to investigate domestic treatment efficiency of a subsurface wastewater infiltration (SWI) system over time. The performances of a young SWI system (in Shenyang University, China, fully operated for one year) and a mature SWI system (in Shenyang Normal University, China, fully operated for seven years) under the same operation mode were contrasted through field-scale experiments ...

  • Domestic wastewater treatment by a constructed wetland system planted with rice

    The experiments were conducted in four concrete laboratory scale free water surface constructed wetland units 1 m wide, 1.5 m long and 0.8 m deep. Paddy field soil was added to a depth of 0.4 m and rice seedlings (Oryza sativa L.) were transplanted into the units at a density of 25 plants/m2. Domestic wastewater collected from Chiang Mai University was applied into each unit via two different ...

  • A comparative study of greywater from domestic and public buildings

    Greywater (GW) can be an important resource for urban water consumption, replacing potable water for purposes that do not require drinking water quality. If applied on a large scale, this practice will reduce the potable water demand and the wastewater produced in urban areas, minimizing the negative impacts and costs of water extraction and wastewater treatment. A correct characterization of GW ...

  • Challenges in addressing variability of lead in domestic plumbing

    Current data indicates that lead exposure is of concern even at low concentrations. Corrosion is an important problem in drinking water because it can affect public health due to leaching of lead or other metals into the drinking water. For this reason, a corrosion control program is an important measure to help mitigate exposure to lead in drinking water. The biggest challenge that remains in ...

  • Top Tips for Using Rainwater Domestically & Commercially

    Did you know that rainwater can be used (instead of mains water) for a huge number of activities and tasks domestically and commercially (inside and outside). As an alternative water source, rainwater recycling can help reduce typical household water usage by up to 70%, with hot water applications by as much as 85%. ...

  • Demand for domestic water from an innovative borehole system in rural Ghana: stated and revealed preference approaches

    This study investigates demand for domestic water supply from an innovative borehole system using the contingent valuation method (CVM). We further estimate demand for current service of domestic water supply in residences using the hedonic pricing method (HPM). This is achieved through a survey from rural districts of the Greater Accra Region, Ghana. Interval regression and ordinary least ...

  • An Infrastructure Grows · Decentralized Treatment and Recycling Domestic Wastewater

    THE TERM, “decentralized waste-water management,” refers to the process of treating and discharging treated wastewater in the local vicinity where it is generated. Decentralized systems typically use the soil as the final receptor of the treated wastewater instead of discharging to surface waters, which are generally the receptors of treated wastewater from larger centralized treatment plants. ...


  • Hydrodynamic characterisation of an airlift reactor for domestic wastewater treatment

    This study evaluates the hydrodynamic and mass–transfer behaviour of a 20–L airlift photobioreactor, employed for secondary wastewater treatment of domestic effluent. Gas hold–up (ε), as well as the volumetric mass transfer coefficient (kLa) was assessed as a function of superficial gas velocity (Ug) for both bi– and triphasic systems. In the experimental range of Ug ...

  • Sewage Treatment - Klargester is the market leader for small and medium-sized domestic treatment plant and waste water treatment systems in the UK

    Sewage treatment plant operate by providing an environment in which aerobic bacteria are cultured. These bacteria survive by using biological matter in the sewage as a food source. To provide optimum treatment the bacteria need free access to oxygen and immersion in the sewage effluent. The majority of package plant work by providing a fixed medium that the bacteria adhere to, and a means of ...

  • Floating treatment wetlands for domestic wastewater treatment

    Floating islands are a form of treatment wetland characterized by a mat of synthetic matrix at the water surface into which macrophytes can be planted and through which water passes. We evaluated two matrix materials for treating domestic wastewater, recycled plastic and recycled carpet fibers, for chemical oxygen demand (COD) and nitrogen removal. These materials were compared to pea gravel or ...
