Major break through for Veligonda project, MEIL completes 2nd tunnel excavation
  • The Poola Subbaiah Veligonda irrigation project crossed a significant milestone on Tuesday. Contractors, the Megha Engineering and Infrastructures Ltd (MEIL), completed the excavation works on the 7.5-km-long second tunnel, using advanced tunnel boring machines (TBMs).
  • The tunnel excavation works for the mega irrigation project started 15 years ago. The project progressed slowly.
  •  A review was done in 2020 when the YSRC government assigned MEIL to undertake the pending works on both tunnels.
  • MEIL completed the 3.6-km-long first tunnel in 13 months by January 2021. With the breakthrough for the second tunnel now, the project is on the verge of completion.
