“…The average counts were higher than that of the fecal bacteria, especially in the TGW + Cl 2 ( Table 2). This confirms the findings of Benami et al (2015) who showed that P. aeruginosa seemed less susceptible to chlorination than enteric and indicator bacteria. Nevertheless, P. aeruginosa is rarely mentioned in existing wastewater effluent and GW reuse guidelines (Maimon et al, 2010;WHO, 2006).…”

“…Studies conducted by Eriksson et al (2002) and Ottoson and Stenstrom (2003) revealed a large collection of excreta-related pathogens associated with greywater . Other studies have further identified a number of pathogens in greywater, and these are Pseudomonas (Benami et al 2015a; Khalaphallah and Andres 2012), Legionella (Birks et al 2004), Giardia (Birks et al 2004; Birks and Hills 2007), Cryptosporidium (Birks et al 2004) and Staphylococcus aureus (Benami et al 2015a; Kim et al 2009; Maimon et al 2014; Shoults and Ashbolt 2017) in greywater. Table 3 presents some selected biological parameters with their concentrations as reported in other studies.…”

This paper presents a literature review of the quality of greywater generated in different, especially developing, countries, constituents found in greywater, some treatment systems, natural materials for treatment, some reuse strategies and public perception regarding greywater reuse. The review shows that generation rates are mostly influenced by lifestyle, types of fixtures used and climatic conditions. Contaminants found in greywater are largely associated with the type of detergent used and influenced by other household practices. Many of the treatment systems reviewed were unable to provide total treatment as each system has its unique strength in removing a group of targeted pollutants. The review revealed that some naturally occurring materials such as Moringa oleifera, sawdust, can be used to remove targeted pollutants in greywater. The study further showed that user perceptions towards greywater treatment and reuse were only favourable towards non-potable purposes, mostly due to perceived contamination or lack of trust in the level of treatment offered by the treatment system.

“…This allows pathogens to enter the greywater system and therefore provide a risk of infection to those who come into contact with the greywater, for example, following garden irrigation (Casanova et al 2001;Ottosan and Stenstr€ om 2003). Greywater has been shown to contain multiple micro-organisms, including Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, Shigella spp., Klebsiella pneumoniae and Salmonella enterica (Winward et al 2008;Benami et al 2015). Although variable and highly dependent on the household from which the greywater originates, the potential presence of such pathogens is a major impediment for greywater reuse (Benami et al 2015).…”

Potential for microbial contamination is one of the limiting factors for domestic greywater reuse. Although subsurface irrigation is considered to be one of the lowest risk applications, there is still a possibility of microbes reaching the soil surface if the environmental conditions are not favourable or if soil movement inadvertently exposes the irrigation line. In these circumstances, the soil cover layer may be contaminated by greywater microbes. This study assesses the survival rates of the pathogen indicator organism Escherichia coli in three soil cover materials commonly used worldwide and makes clear recommendations to facilitate the safe reuse of domestic greywater.
