This study aims to evaluate the potential of greywater availability in Muscat Governorate in the Sultanate of Oman, to establish a methodology for greywater quantity estimation, to test greywater quality in order to assess reuse potential, and to examine public acceptance for reuse.Total fresh water consumption and greywater generation from different household sources were measured by water meters in five selected households during summer and winter. Additionally, a survey was designed and conducted in five administrative areas of Muscat Governorate, with the objective of testing a methodology for estimating greywater generation potential in these areas. Collected data were compared with that used by the Ministry of Housing, Electricity and Water, Sultanate of Oman. The survey covered a total of 169 houses and 1,365 people. Greywater samples were collected and analyzed from showers, laundries, kitchens and sinks in some of these households to determine their water quality parameters. Statistical analysis results indicated that there is no significant variance in the total fresh water consumption between data used by the ministry and those measured and estimated during this study, highlighting the applicability of the tested method.

The physical, chemical, and biological analyses of the grab samples revealed that greywater contains significant levels of suspended solids, inorganic constituents, total organic carbon, chemical and biochemical oxygen demands, total Coliforms and Escherichia Coliform bacteria. The public acceptance survey illustrated that approximately 76% of the respondents accepted the reuse of greywater for gardening, 53% for car washing and 66% for toilet flushing. PMID: 17562209 [PubMed - as supplied by publisher] City codes (and fines) may impact your use of grey water. Best systems have plants to filter the running water and sand to cover the standing water in order to avoid providing mosquito habitat ($5,000). Biggest bang for your buck would come with drip irrigation with either standard drip lines or modified PVC. -- FB - FFF Billy http://angryarab.blogspot.com/ |

Most don't have a toilet, as we know it, in Oman. Considering all the chemical oddities in laundry detergent, sink/toilet cleaning chemicals, people cleaning chemicals, and so forth; I would reconsider that thought about reuse of grey water. Really a smorgasbord of who knows what. If one can revert to lye soap and herbs for smell, go for it. Dave |
