Improvement of the pressurization station SPP 41 from the irrigation system of Ograda, Ialomita County, Romania

Abstract

Abstract The water supply of the arrangement is made from the Danube through the I.M.Gheorghiu base station and is pumped into the CA Lunca Canal. The outlet of the floating station is on the Crcome arm of the Danube River at 221 + 650 km. The flow required for the Ialomiţa Călmăţui terrace is 110mc / sec. The 6.7 km long Lunca CA channel runs water through the Călmăţui-Gropeni meadow to the base of Mihai Bravu terrace to the north of Spiru Haret locality, from where through the SRPA1 Spiru Haret repacking station, it is raised on the terrace and directed on the AC adduction channel. This channel is dimensioned in 3 sections: the first section with a length of 12.445 km crosses the area from the discharge basin of the SRPA1 Spiru Haret refueling station to DN21 Slobozia-Brăila, which it intersects south of the town of Inssuraţa; the second section is between DN21 (km12 + 445) from the channel and the SRPA4 station at km30 + 835; the third section with a length of 2690 m is between km30 + 835 and km33 + 525. From the main channel of adduction CA Terasa derives in the following channels: CD1 at km2 + 285, CD3 at km10 + 750, CD7 near the SRPA3A station and CD9 fed from the downstream end of the channel CA Terasa. The total length of the channels of adduction and distribution in the perimeter of Ialomiţa Călmăţui is 318,886 km, the net surface of 137291 ha arranged for irrigation and is composed of 512 plots generally rectangular in shape. From the CD3 channel, the CD5 channel is formed stage 1 in the length of 14.3km from which SRPA4 Bucşa is fed. This refueling station supplies 13.1km long CD5 channels and CD4B, CD4C. The latter channel feeds the SPP41 pressurizing station serving 1692 ha belonging to OUAI Ograda. The proposed works will be limited to the refurbishment and consolidation of the SPP41 pressure pumping station.
