LHWP tunnel closure won’t have significant impact on water supplies, assures DWS

The upcoming six-month closure of the Lesotho Highlands tunnel, from October 1, 2024, to March 31, 2025, for scheduled maintenance is not expected to have a significant impact or disruption on Gauteng’s water supply. The shutdown will result in an 80-million-cubic-metre shortfall during 2024 in the water supply from the critical Lesotho Highlands Water Project (LHWP) to the Integrated Vaal River System (IVRS).
