1.3 Pump Houses\n\n## 1.3.1 Present Status\n\nBoth the Hurga and Nur El Din pumping stations situate at the concave right bank of theBlue Nile where the water flows along the right bank.These pumping stations are said to bebuilt in approximately 1958,about 30 years back.The maintenance and repair works during thoseyears seem to have not been done satisfactorily due to difficulty in supply of spare parts andappropriate technical support.The superstructures of both pumping stations have beendeteriorated severely in comparison with other pumping stations constructed at almost the sametime along the Blue Nile such as Wad EI Nau and Hag Abdalla pumping stations.The presentstructural conditions of both pumping stations are outlined hereunder:  \n(1)  \nHurga Pumping Station  \nThree suction pits are built into the river bank with a brick made building for placingthree diesel engines.According to the geological analysis conducted by the JICA Study Team,these suction pits are assumed to be on stiff clay of2-8m or a stratum underlying thereof.  \nThe building is made of steel framed brick masonry walls and corrugated slate roof,whilethe suction chambers are made of reinforced concrete.The materials of the main structures areenumerated as follows:  \nSuperstructure  \nRoof  \nCorrugated slate  \nWallBrick masonry and slate  \n-  Roof frame  \nStructure Steel  \n-  Column  \nStructure Steel  \n-  Foundation  \nReinforced concrete  \nSubstructure  \n-  Suction chamber  \nReinforced concrete  \n-  Intake structure  \nReinforced concrete  \nDischarge chamber :  \nBrick masonry  \nPlain round bars(9-19 mm in diameter)were observed on some parts of the walls of thesuction pits and retaining walls of the intake structure where reinforcing bars were exposedbecause spalling of cover concrete has occurred or cover concrete has not been casted adequately.The reinforcing bars exposed have been corroded seriously.The state of those embedded in theconcrete is quite good in condition according to observation by tipping cover concrete on the insidewall and the floor of the suction pit during the current study period.The bar arrangement of thesaid floor is:main bars with 19 mm in diameter at 10cm intervals and distribution bars with 13mm in diameter at 20cm intervals.The same at the said wall is:vertical bars with 10 mm indiameter at 10cm intervals and horizontal ones with 10 mm in diameters at 20cm intervals.No  \ncracks have been developed in any of reinforced concrete members.A slight seepage wereobserved on the walls at lowermost part of a suction chamber during the study period.It is likelyto increase when river water goes up.The river bank at both upstream and downstream sides ofthe pump house is protected by mortar stone masonry,whose condition is fairly good.  \n(2)   Nur EI Din Pumping Station  \nThe pump house consists of a pump room with two partition walls built into the river bankand a building for placing three diesel engines.The floor slab of the pump room is concrete made,and most of other structures are of brick masonry.The floor elevation of the pump room is 8.15mbelow the diesel engine fioor.The walls of the pump room are made of brick masonry and becomesthicker stepwise towards the bottom,forming a sort of gravity type retaining walls.Many tracesof seepage were observed on the walls especially on the river side wall durign the study period.Each partition wall of the pump room is made of brick masonry at its upper portion,whilereinforced concrete at the lower portion.Round reinforcing bars with 9 mm in diameter are onlyhorizontally arranged at a 30cm interval in the brick walls of the pump room.The building ismade of steel framed brick masonry walls and corrugated slate roof supported by steel frames.Theriver side wall of the pump room is covered by earth surfaced with dry stone masonry,however,considerable part of the stone masonry at center of the slope has been collapsed.  \n##
