Karachi:
The Karachi Water & Swerage Corporation (KWSC) engineer (KWSC), ASADULLAH KHAN, published a detailed video declaration on the causes and repair measures linked to Rafale water lines in Siphon 19 near the University of Karachi.
He explained that the water pipes in the region have several decades, with one installed in 1956 and the other in 1971 – which made them respectively 69 and 54. Their designated lifespan has expired for a long time. He said that Siphon 19, located near the University of Karachi, has two 84 -inch reinforced concrete cylinder pipelines, one of which is 16,000 feet (about five kilometers) long. Siphon 19 begins in the city of Saadi and extends to University Road.
COO noted that U -U pipelines to the siphon increased water pressure considerably. The water flowing through these U -shaped sections generates much more pressure compared to the straight duct lines. As a result, old and weakened pipes are unable to withstand additional pressure, which makes them burst.
He said that Dhabeji’s operating pipelines in Karachi are direct conduits and do not undergo this increased pressure, which is why they remain intact. He also shared that the damaged PRCC line at Siphon 19 is replaced by a soft steel pipe (MS). To ensure sustainability, four tonnes of melted lead, heated to 300 ° C, will be paid to the two ends of the pipe. The process is called to pour the lead. He expressed the hope that the repair work would be completed by Saturday evening, after which the water supply should return to normal. He apologized to citizens for the inconvenience caused.
Gap
Meanwhile, experts said that repairs from the seven -footed pipeline, initially expected on Saturday, were now to continue until Sunday. They said that even if, by chance, KWSC manages to complete the repair work by Sunday, an additional period of three days would be necessary to normalize the supply of water to the city.
