Water & Wastewater Treatment

PUMPS AND PUMPING SYSTEMS the pump was installed in order to give greater suction. Coupled with all these engineering works was the need to equip each PS with secure control panels for the remote operation of the pumps. Commissioning On completion of the engineering and construction programme, KSB engineers had installed and commissioned 13 Amacan pumps with flows ranging from 0.5m³/s to 4m³/sec, increasing the drainage pumping capability of the Petit Camargue from 19.8m³/sec to 45.3m³/ sec. For KSB, this project proved to an exacting examination not just of its pumps, but also its hydraulic and civil engineering capabilities. As a result of this major investment, which was jointly financed by Europe, the French state, the region of Languedoc-Roussillon, the Department Garde and the Syndicat Mixte Départmental des Milieux Aquatiques, the SMCG now has a robust flood prevention scheme that is capable of handling the flood levels encountered in 2003. nnn At La Cave/Le Mole PS, a special 'tulip'- shaped cone was designed and constructed at the end of the tube in which the pump was installed to give greater suction chambers in the feed basin in which the pumps were installed to counter the vortex effects on the water surface which could damage the pumps. At the la Cave/Le Mole station, a special tulip-shaped cone was designed and constructed at the end of the tube in which Irrigation project demands mega motors Pumping water along the world's fifth largest tunnel required some serious pumping, says motor manufacturer WEG B razillian motor manufacturer WEG has supplied the Suruç Plain Irrigation project in Turkey, which includes construction of the fifth largest tunnel in the world. The project aims to provide drinking water and water for crop irrigation to Suruç City and its 135 residential areas. Work on an irrigation canal began in March 2009. It is currently in the excavation phase, which was expected to be completed by the end of 2013. Besides the irrigation canal, a 17km tunnel, designed to transport 90t/s of water, is under construction. The project needed robust pumps and equipment to move the water from the Atatürk dam in the Euphrates River to the irrigation canal. WEG has supplied eight medium-voltage asynchronous motors, to drive the pumps that transport water to the irrigation canal. Each motor is 4m tall and weighs 34t. wwtonline.co.uk Eight medium-voltage asynchronous motors in situ Drought Two years of drought has increased the deprivation of Turkey's poorest population. Without water to drink or irrigate crops, some 70,000 inhabitants of this agricultural district are suffering. The region has received funding for economic development as part of the £20Bn Southeastern Anatolia Program (GAP), which is focused on improving energy, irrigation, social infrastructure and international cooperation. The water resources development section of the programme involves the construction of 22 dams, 19 hydraulic power plants and the irrigation of 17,000 km2 of land. WEG says it has a 20-year relationship with distributor Dal-Group, who supplied the pumps to contractor, Ankarabased Samsun Makina Sanayi. Özer Ertokmac, sales & service manager of DalGroup, said, "This project is very important for Turkey since it aims at stimulating the migration to the north-east of the country, thus relieving big cities and improving the population's income and life quality in the region." nnn January 2014 Water & Wastewater Treatment 25
