Potentiality of waste water reusing in Iraq

الملخص EN

Reusing of treated wastewate r effluent, which is normally disc harge d to the environment from munic ipal waste water treatment plants, is re ceiving an increasing attention as a reliable water resource.

The volume of this re source may be worthily taken into consideration in the planning and implementations of water re source s projects.

Currently most of the Middle East countries have developed their own expe rience in this fie ld, however, among these countries Iraq has nothing to do in this field, a case whic h make one feels sorrowful.

Therefore , in this work, suc h te chniques have be en analy tically discussed, and handy sy stems of drip irrigation methods for using treate d waste water in Iraq have bee n proposed.

Moreover, in this pape r, a pioneer research study has been carried out as a leading effort on this promising field of recycling wastewater usage in Iraq.

For the time being, it has been detected that about 1 million cubic meters in the city of Baghdad only is disposed every day to Tigris river after getting secondary treatment, It has been shown that in 2020 the amount of wastewater in the city of Baghdad may increased to as much as (4388264) m3/day , which (if treate d) may irrigate as muc h as (43882)hectare of industrial crops, or to be use d for planting a green belt of tre es surrounding the whole city of Baghdad, this could help in damping the dust storms which became a predominant phe nomena in the last few y ears.

It is also shown that the concept of dece ntralization sewage treatment plants and se paration of gray water in source may be the most dare ste ps to be taken by the authorities to compl y with the new era of wate r reuse management in Iraq.
