Tauranga City Council is urging residents to watch their water usage after demand reached a record high, yesterday.
City waters manager Steve Burton said if nothing changed, the council would need to restrict outdoor water use.
"There's enough for everyone if we're mindful of how much we use and where we use it," Burton said.
"Please avoid using sprinklers and if you have a garden hose, make sure you're using it only where it's needed."
With more people living in Tauranga than ever before, the city's water supply is under increasing pressure, particularly over the summer months, Burton said.
