Water rationing may be avoided in Gisborne with conservation efforts reaching targets, the council says.
The pipe from the city's Mangapoike Dams burst on Monday afternoon when the hillside around it slipped.
Gisborne District Council deputy chief executive Peter Higgs said the target for water consumption was less than 14,000 cubic metres per day, which was achieved yesterday.
Contractors were working on the site 24/7 to complete the repairs, he said.
"We are now expecting that the pipe will be repaired and the water flowing again by mid next week," he said.
"In the meantime it is vital that we all keep our water use to a minimum."
Until the pipe could reliably bring water from the Mangapoike Dams into the Waingake treatment plant, emergency supplies from the Waipoa treatment plant would be relied on, Higgs said.
Extra pressure would be put on the water supply next week when major food processors would ramp up production, Higgs said.
Council chief executive Judy Campbell said that even when the pipe was up and running, it would be a while before it was running at capacity.
"We will need people to be careful with water until the end of summer," Campbell said.
Until the water is flowing again, the council has imposed a fire ban, forbidden the use of sprinklers or hoses, and the Olympic pool closes 2 hours early each day.
