Water consumption for last week stood at 576m litres per day which was, on average, 18m litres per day more than the week before.
The hot weather is also likely to see an increase in the number of tourists visiting the city although some local residents leave town during peak holiday season.
In a press statement the city pleaded with water users to be water-wise and to “build on the good conservation practices they adopted to beat the drought”.
Visitors to the city unsure about water restrictions are encouraged to visit the city’s website.
