"Hamilton's levels of water use are close to triggering further restrictions. We are currently using significant amounts of water every day in Hamilton, at a much higher level than what we've seen at this time of year in the past. If this level of use increases, or continues for too long, Hamilton will need to consider moving to Water Alert 3, which means handheld hosing only."
"Small changes to outdoor water use can make a big difference overall. If your sprinkler is on a timer, reduce its running time, or if you don't have a timer, set an alarm on your phone to remind yourself to turn it off sooner," says Mr Fowles.
Waipa District Council's water services manager Tony Hale echoes these warnings.
"In Waipa we are facing a serious shortage of water due to an increase in demand from residents, but also with the lack of rain affecting our supply.
"If people don't cut back on non-essential water use for their gardens and swimming pools there is less available for essential services such as water for drinking, showers and toilets."
The 'Smart Water Starts with You!' sub-regional summer campaign, a joint venture between the Waikato District, Hamilton City and Waipa District Councils, aims to bring about long-term change in how we use water.
