24 2.6 Conclusions Treated wastewater reuse in Jordan, a water strained country, has been practiced as part <strong>of</strong> public water policy. Government organizations cater for such reuse. Irrigation projects were implemented in the Jordan Valley using treated wastewater blended with storm water impounded by the King Talal Dam. While treated wastewater reuse has been formalized, no attempts have been made to regulate through legislation the reuse <strong>of</strong> greywater at the household level. Limited projects were implemented in the greywater reuse at the household level in Jordan and appraisal <strong>of</strong> them indicated the viability <strong>of</strong> expansion. The socio-economic impacts and environmentally protective practices encourage the expansion <strong>of</strong> greywater reuse. Recommendations are made to enhance greywater reuse outside the centralized wastewater collection and treatment systems. 2.7 References • CSBE (Center for the Study <strong>of</strong> Built Environment) (2006). http://www.csbe.org/ about_csbe.htm Site accessed on 20 December 2006. • Faruqui N. and Al-Jayyousi O.

25 3. Financial and Economic Analysis Report 2 3.1 Introduction Any wastewater generated at home, except water from toilets, is called greywater. Dish washing, shower, sink, and laundry greywater comprise 50–80% <strong>of</strong> residential wastewater. Greywater may be reused for irrigation, especially landscape irrigation. Contaminated or difficult-to-handle greywater, such as solids-laden kitchen sink water or water used to washing diapers, “dark greywater”; is considered as black water by most regulators. However, the level <strong>of</strong> pathogens in even the darkest greywater is less than <strong>of</strong> that in black water. Wastewater without added solids, such as warm-up water from the hot water faucet, reverse-osmosis purifier drain water, or refrigerator compressor drip, is called clear water. The society in Jordan is becoming more water conscious due to shortage, population growth and drought. At the same time, there is concern about the impact and waste <strong>of</strong> sewage and effluent disposed from sewage treatment plants into our environments. Greywater is becoming a valuable commodity that could be used efficiently at dwelling basis in many regions around the world.
