MIDCOAST Water says water usage has increased 15 per cent across the region since the start of September.
The service provider says it is monitoring water levels in the Barrington River as well as all other waterways in the region and could start enforcing restrictions if customers do not start to rein in their usage.
“Water use has been climbing slowly since the start of September, with last week’s usage almost 188 million litres,” MidCoast Water chairman David West said.
“We are currently using 15 per cent more water than average usage over the last seven years.”
River levels are low, with just 66 megalitres recorded flowing in the Barrington River on October 1.
“However the figure is changing daily,” a spokeswoman for MidCoast Water said.
“On October 3 it was 83 mega-litres so it can and does fluctuate.”
The Manning River has fallen and if dry conditions continue could be at critical levels by early to mid-November.
The water authority’s summer water saving program came into force with the introduction of daylight saving on the October long weekend.
The program applies throughout daylight saving to reduce the amount of water used during the warmer months.
It applies to households, businesses, parks, gardens and sporting grounds across the local government areas of Gloucester, Great Lakes and Greater Taree.
“The program’s main message is simple - don’t spray in the middle of the day,” MidCoast Water general manager Robert Loadsman said.
All fixed hoses, sprinklers and microspray systems should not be used during the hottest part of the day between 10am and 4pm.
“We hope to once again be able to get through the hot weather without the need for water restrictions,” Mr Loadsman said.
