Residents living in Wellington's CBD are asked to flush the toilet only if essential and minimise the use of inside drains, due to a burst water pipe.
Wellington City Council advised of the burst pipe, at the intersection of Victoria and Mercer Sts, yesterday.
Work to fix the pipe was likely to affect traffic on Victoria St and Jervois Quay on Tuesday, and Mercer St remained closed.
Wellington Water said there was no indication wastewater had gone into Wellington Harbour but the public were asked to stay out of Whairepo lagoon in the meantime.
