Kevin Stent/Stuff Extensive repair work on pipes beneath Mt Albert at Island Bay ran for months in 2020, and now residents have been told there is more to come. (File Photo). Island Bay residents are being told to expect three months of foul odours due to maintenance work on a major sewerage pipe. It’s another kick in the guts for a community that suffered through months of the “overpowering” stench of sewage after extensive damage was found in a pipe deep beneath Wellington in 2020. Two four-metre-deep excavations will be dug into the road at the corner of Adelaide Rd and Dover St, so crews can remove, refurbish, and reinstall valves on a large sewerage pipe.
