ubulu-uku is situated some thirty kilometres (30kms) west of the river niger in aniocha south local government area of delta state. eastwards it shares a boundary with ogwashi-uku, westwards with obior; northwards with issele-uku and southwards with ubulu-unor. ubulu uku is sited in an undulating environment with its enugu-iyi and abuedo end at the top of a long stretch of hills, while its centre,
fanning out from the ubulu tree, to isho, akwu, ogbeofu, idumu-osume etc are located in a valley. rolling down these hills are rivers which run through the entire clan to the sea through other neighbouring clans. topograhically it is a hilly town that could be easily compared to agbor in delta state, auchi in edo state and ibadan in oyo state. this hilly nature of the town accounts for the serious problem of erosion which it faces. the problem has made some of the streets impassable especially the street leading from the major road to ogbeofu. on the other hand when one looks at the town from any of the hilly spots especially at night, one sees a beautiful scenery that could be said to be one of the best that nature has bestowed on this part of the earth. the town has one major stream called iyi-agor which was the main source of water supply before the advent of pipe-borne water. a few other minor streams like nkpitime-isho, iyi-nta, iyi-eko and iyi-ozala also serve people in various parts of the town. three major roads run through the town . one runs from asaba via ibusa to ogwashi-uku then through ubulu-uku to obior and umunede. the second road branches out from ubulu-uku to umunede road at idumu-osume village via akwu village and then to issele-uku. the third road branches out from ubulu-uku to umunede road at the post office junction and runs through akpama, agbonta-udogwu and isho village to ubulu-unor.
