Study of the Reuse of Greywater in the Irrigation of the Home Garden in Rural Areas
Ali Hadi Ghawi
Abstract: Greywater is an important water resource at the household level. It includes water from household operations such as cooking, washing, cleaning and other household processes. The reuse of greywater is one of the most promising ways of conserving water because it has an important role in increasing plant productivity at the garden level. It is an important option for increasing the efficiency of water use at the household level in rural Iraq as well as treating water scarcity. Many homes in Iraq are drained of wastewater through cesspits, especially in the countryside and urban areas, leading to groundwater and surface pollution. A greywater treatment compact plant has been designed and implemented at the household level and used to irrigate the home gardens because we have seen a benefit that can be achieved for the family, especially, the community at large. This project, through the implementation of a greywater treatment unit in the rural areas of Al Diwaniyah governorate has sought to develop the treatment technology and exit the local community in rural areas to encourage their reuse. The aim of this study is to highlight the rationalization of the uses of water resources through the use of greywater. It aims to deepen the knowledge and transfer of the relevant expertise in this field and to define the interested parties in this field and to build their capacities in the greywater issue and how they can be separated of the use of greywater in Iraq. The greywater treatment unit in the village of Khairi in Al Diwaniyah Province consists of a septic tank, up-flow anaerobic filter, a multi-layer aerobic filter amd a storage tank. To ensure the quality of treated greywater used in irrigation, a periodic water monitoring program was implemented before entering and after treatment. The percentage of removal of suspended solids reached 94% and the nitrogen removal rate was 85 %. This results are encouraging and excellent. The results of the test and analysis that the plant has a high processing efficiency of up to 97% for BOD and conform to the specifications of water used for irrigation.
