The Clutha District Council has imposed summer water restrictions which apply across the region.
Chief executive Charles Hakkaart said the stage one "summer mode" restriction, imposed on Friday, meant watering was restricted to between 8pm and 8am.
Watering systems and sprinklers could be used during these times, but must not be left unattended.
The council might grant exemptions on a case-by-case basis to commercial properties and for irrigation, depending on the level of restrictions in place, the extent of the dry period, and the time of the year.
Mr Hakkaart said the minor restrictions were designed to ensure there was sufficient water throughout the summer and more severe restrictions could be avoided.
