The dam is equipped with canal headworks, located on its left bank, which divert water into a canal. When water levels in the reservoir are low, three pumps move water into the canal.

The main portion of the dam is an earthen embankment; the spillway and irrigation headworks sections are concrete gravity.{{cite web|last=Ahmad |first=Siyam |title=Assessment of The Current State of The Nile Basin Reservoir Sedimentation Problems |url=http://www.nbcbn.com/Project_Documents/Progress_Reports/RM-G1.pdf |publisher=Nile Basin Capacity Building Network |accessdate=16 February 2013 |page=A3 |url-status=dead |archiveurl=https://web.archive.org/web/20101009041327/http://www.nbcbn.com/Project_Documents/Progress_Reports/RM-G1.pdf |archivedate= 9 October 2010 }} The dam has a small hydroelectric power station, which was upgraded during the period 2002–04 to its current installed capacity of {{convert|10|MW}}.{{cite web|title=Khashm Algirba Dam |url=http://www.shgc-sd.com/khashm-dam.html |archive-url=https://archive.today/20130411191603/http://www.shgc-sd.com/khashm-dam.html |url-status=dead |archive-date=11 April 2013 |publisher=Sudanese Hydro Generation Co Ltd. |accessdate=16 February 2013 }}{{cite web |title=Khashm El Girba Hydro Power Station Rehabilitation (2002-04) |url=http://heavyengineering.co.ke/KhashmHEPP200204.php |publisher=Heavy Engineering Ltd. |accessdate=16 February 2013}}
