The Western Bay of Plenty District Council is asking Katikati residents to conserve water.
A large water mains break in the area was placing a very large demand on the water system, the council said in a statement on its website.
Due to the large scale of the leak, water was turned off at the top end of Busby Rd to avoid running out of water.
"The mains break is in a stream and cannot be repaired due to the flow in the steam and depth," the statement said.
"We are going to install a temporary water main which will be suspended over the steam and have commenced work at the site."
