Hamilton City Council is asking residents to cut back on non-essential water use to reduce the need for additional water restrictions.
Currently Hamilton is on Water Alert 2, which means sprinklers and watering systems can only be used on alternate days between 6 and 8am and 6 and 8pm.
Waipa District Council has moved to Water Alert 3 after water use increased and water availability decreased, due to lack of rain in the region. Waikato District Council is currently at Water Alert 1.
Hamilton City Council water compliance manager Trent Fowles said the council's focus is on educating and assisting Hamilton residents to be mindful of their water use.
"We need people to stick to our current sprinkler restrictions, and to generally be smart about their non-essential water use, especially outside.
