Abstract:

<p>Greywater is domestic household wastewater without inputfrom the toilet, i.e. wastewater from sinks, the shower,washing machine and dishwasher in a home. Source separation ofgreywater can be a strategy to enhance recirculation of plantnutrients and/or improve water use. The risk for transmissionof disease when reusing greywater is largely dependent on thecross-contamination by faeces. High levels of faecalindicators, mainly thermotolerant coliform bacteria, have beenreported in greywater, indicating substantial faecal pollution.However, growth of indicator bacteria within the system leadsto

<p>The purpose of this study was to investigate the various types of onsite greywater treatment facilities available at two housing communities (Hull Street and Moshoeshoe Eco Village) in Kimberley, South Africa. The objective was to undertake a close observation through personal experience of the installations, measure water consumption and greywater produced, do an inventory of household cleaning chemicals and conduct interviews of different stake-holders of the Housing Project to find out their views on greywater and Ecosan issues. The study was conducted between June and August 2006.</p><p

Abstract:

Though Canada has a perceived abundance of fresh water resources, they can be affected by localized drought, changing weather patterns and aging infrastructure. Greywater collected from sinks, baths, showers and washing machines can provide an alternate source of non-potable water, improving the security of fresh water resources in Canada. The agriculture sector is one area where greywater could be put to beneficial use. Farming at the rural-urban interface has been growing in popularity within North America, and provides farmers with new opportunities as they attract more visitors to the far

Australia is one of the driest continents in the world with changing climatic conditions continuing to put a strain on potable water sources.

To this end, Master Builders Association Victoria with the assistance of RMIT University investigated the current barriers that builders face with regard to the installation of greywater systems in residential properties.

The potential of four pilot-scale wastewater treatment processes for in-building greywater recycling has been assessed. The evaluation of three membrane bioreactors (MBRs) and a biological aerated filter (BAF) was principally with reference to the non-potable water reuse quality standards. In the steady-state trials the feedwater quality was changed from synthetic greywater to blackwater (primary sewage influent) simulating the variability of domestic wastewater. The submerged MBR met both the chemical and microbiological water reuse quality standards independent of the feedwater strength. The

Aggravation of water scarcity, eutrophication and pollution, has led to treatment and/or recycling of the major fraction of domestic wastewater, which is grey wastewater, for non‒potable options.

In the present study, a novel synthetic greywater composition has been proposed with respect to the composition of organics, nutrients, heavy metals and other trace elements.

In the past decade, the world has witnessed a huge expansion at a progressive rate of its population, its urban density, and its water use. As the world’s population steadily grows, so too does global understanding of finite resources, with society increasingly looking towards technology to facilitate the epic task of managing natural resource usage. This increasing pressure on finite water resources clearly manifests itself in today’s context of increasing water restrictions and rising water costs.

Abstract:

This study focuses on the feasibility and environmental impacts of using raw domestic greywater from laundry and bathroom after only primary treatment, e.g. coarse filtration for irrigating lawns and gardens.

There is the possibility that excessive nutrients and other contaminants will leach into surrounding water bodies.

Abstract:

The intent of this project is to provide tools for public administrators to implement and evaluate the cost of an alternative on-site residential water supply using rainwater harvesting and greywater reuse in their jurisdiction. These tools are then applied to the city of San Luis Obispo (SLO), California as a case study to demonstrate how rainwater harvesting and greywater reuse could be implemented to supply all residential potable and non-potable water needs, completely replacing the current centralized publicly-managed water system. Further, energy and direct fiscal costs of the alternativ

Abstract:

Of the total amount of domestic potable water used in Perth, 43% is used for irrigation (MWA, 1985). Some people have suggested the reuse of greywater to reduce the use of potable water. Greywater is wastewater that originates from bathroom and laundry sinks, showers, and in some cases, the kitchen sink (Rose et al., 1987). A community garden project in South Fremantle called King William Park (KWP) was begun in 1994. Part of the project involves the sub-surface irrigation of two areas in the park by greywater from two nearby houses. My project therefore involved assessing the environmental

Abstract:

In Perth, domestic irrigation constitutes over 50% of the total urban scheme water demand and at a time when urban water resources are diminishing, greywater reuse has the potential to enable significant reductions in scheme water consumption to be achieved. Greywater technology has been slow on the uptake in Western Australia as there has been greater focus from State government and Water Corporation on large scale water supply augmentation, such as seawater desalination. Some debate exists as to how useful greywater reuse can be in contributing to scheme water savings as limited studies have

The widespread practice in Latin America of separating greywater from blackwater at the domestic level lends itself to the application of Ecological Sanitation, or Ecosan. In this research simple, low-cost subsurface flow wetlands, or reedbeds, were investigated not only for their potential in treating the greywater component but also to evaluate their acceptance as an appropriate Ecosan technology in rural Central America. The hypothesis for this thesis is that Ecological Sanitation, namely via reedbeds for the treatment of greywater can improve sanitation in rural Central America. The firs

Thesis (MScEng)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: South African water service providers experience major problems with providing adequate water services to consumers. Water service providers in South African urban areas rely on traditional centralised infrastructure, such as bulk supply networks, to provide water services. Alternative supply and stormwater drainage methods should be encouraged to help mitigate these problems. The researcher thus aims to quantify the potential impact that three alternative methods may have on a given dwelling in terms of its dependence o

For sustainable water management, here is a necessity to consider alternatives, in addition to conventional systems. The aim of this research is to develop and demonstrate a sustainables, from and greywater reclamation system for WC flushing and it was started in 1994. In the UK there are no water quality standards for WC flushing water use. There were no design guidelines for greywater water reclamation and no published study on the supply-dernandb alance, in detail, for water recycling in institutions such as universities. The research has shown the feasibility of planned direct grey and sto
