Activities » Graywater Reuse Project
Support for the CSBE graywater reuse project has been provided by a grant from the Enhanced Productivity Program at the Jordanian Ministry of Planning . Additional support has been provided by the Small Grants Scheme at the British Embassy in Amman .
It is widely agreed that Jordan will face increasingly acute water difficulties during the coming years. Recognition is growing that a ‘business as usual' approach is no longer an option, and that issues related to both increasing supply and reducing demand must be seriously addressed.
The Center for the Study of the Built Environment (CSBE) is implementing a project that aims at investigating, implementing, and promoting graywater reuse at the small and medium scales in the domestic and service sector context. Graywater is the output from bathtubs, showers, sinks, and washing machines, which although soiled, is not as contaminated as toilet water. As such it can be relatively easily treated on-site for reuse in non-potable contexts such as toilet flushing and garden irrigation. Any graywater that can be recovered and reused reduces the overall water demand accordingly, and saves on water bills. Studies in other countries have estimated that the domestic graywater resource could amount to as much as 35% of the total domestic demand.
The project was initiated in September 2002 and will continue until June 2004. The project will consist of several components. It will examine existing applications of graywater reuse in other countries, and evaluate their technical, social, and economic feasibility. Also, it will investigate the social, economic, climatic, and other environmental factors that may have a bearing on the implementation of graywater reuse systems in Jordan, and will develop, in conjunction with Jordanian professionals, graywater solutions suited to the particular context of Jordan. The results will allow CSBE to provide technical advice that would support the implementation of a number of graywater reuse systems and schemes in both urban and rural areas in Jordan. The project also will include the dissemination of practical information on graywater reuse to developers, construction professionals, and the interested public through printed materials and through the CSBE web site.

CSBE would like to thank Richard G. Brittain, Assistant Research Professor at the School of Architecture at the University of Arizona in Tucson, and Val L. Little, Manager of the Water Conservation Alliance of Southern Arizona, for the invaluable help and support they have provided for this project.
Also, special thanks are due to Mr. Shuja' al-Asad for his invaluable help in editing the Arabic-language publications for the project on a pro bono basis.
