Sylhet City Corporation (SCC) has gone one step further towards building a modern and smart digital city by doing away with the lumber of wires and overhead cables and introducing underground electricity transmission system.   The Hazrat Shahjalal mazar area of Ward number–1 of SCC has been completely brought under the system whereby all the electrical pillars and wiring of other services have been removed from view.   Local Power Development Board (PDB) has been installing the underground electric wiring system under its “Power Distribution System Development Project, Sylhet Division”, said a press statement of PDB on Tuesday.   The statement signed by the project director MM Siddik said that the power supply under the new system commenced successfully on January 5 after moving all the overhead electric lines into underground in the Shahjalal mazar area.   Sylhet City Corporation also provided assistance in the project, it said.
