“…Policymakers clearly stated that currently, the wastewater reuse regulations in Oman are not differentiating grey water and black water, and no specific standards are available for greywater. In practice, many households throughout Oman successfully use untreated greywater for irrigation purposes (Prathapar et al, 2005;Jamrah et al, 2008). Legal standards need to be developed to address the use of grey water based on practical factors.…”

“…All reported previous studies on mosques assess the quantity of ablution water and generation of ablution greywater by assuming the mosque capacity (rather than measuring the quantity of water like in this study). No actual measurements with detailed methodology have been reported (Jamrah et al, 2006;Prathapar et al, 2005;Jamrah et al, 2008;Prathapar et al, 2004) nor was an accurate figure for water consumption in mosques provided. Also, most of the previous studies on ablution water investigated issues of water quality of reused/recycled water and/or different ways of recycling (Radin Mohamed et al, 2017;AL-Washali et al, 2020).…”

“…It was found that Jatropha plants irrigated with treated wastewater gave the best growth in term of plant height and green yield compared to groundwater (Al-Busaidi, 2014a). Treatment of graywater and reuse have been extensive studied by researchers in Oman (Ahmed et al, 2008;Jamrah et al, 2008;Prathapar et al, 2005;Ahmed et al, 2005;Ahmed et al, 2004;Prathapar et al, 2004;Ahmed et al, 2003;Ahmed et al, 2012). These studies convincingly showed that graywater in individual households can be utilized in Oman, considering technical, economic, and environmental aspects.…”

Wastewater treatment and sludge management in Oman have been evolving over the years. Sludge utilization has been a challenge due to its association with human waste. Therefore, composting of sewage sludge is the best option in agriculture activities. Sludge and wastewater utilization can add up positively in the economic aspects of the country in terms of creating jobs and improving annual income rate. The number of research projects done on wastewater reuse and other ongoing ones related to the land application of sewage sludge should encourage revision of existing standards, regulations, and policies for the management and beneficial use of sewage sludge in Oman.

The use of treated grey water (GW) for home gardens, peri-urban agriculture and landscaping is becoming popular in many water stressed countries such as Oman. This study aims to investigate the treatment efficacy, health and chemical concerns, cost-benefits and maintenance protocol of a GW treatment system as well as the effect of irrigation with GW on crop yield. Therefore, a decentralized homemade GW treatment system was installed in a newly constructed house in Muscat, Oman and studied over a 2-year period. The treated GW was found to be suitable for irrigation as per Omani standards. GW when mixed with kitchen effluent substituted the use of nutrient supplements for plants and did not show any harmful chemical or biological contamination. The capital cost of the system was around US $980, and the annual operating cost was US $78 with annual income and savings from the system being around US $572 indicating a payback period of nearly 2 years. It was found that the system required simple but regular maintenance particularly cleaning of the top layer of the filter. It can be concluded from this study that such a GW system should be technically, economically and environmentally feasible in Oman. Also, wider acceptance by the general public to the idea of GW reuse will help in mitigating the water shortage problem of the country to some extent.
