Dubbo residents are being asked to help water meter readers gain entry to their properties.
Residents may have to "self-read" their meters if the readers can't get to them.
On Thursday, Dubbo Regional Council (DRC) advised that water meter reading had begun in the city.
It takes place four times a year.
"Under the Local Government Act, DRC can enter private property to carry out water supply work, including meter reading," a DRC spokeswoman said.
"It would be appreciated if residents could assist with providing access."
The spokeswoman said if the meter was in a locked area, or there was a dog in the yard when the meter reader called, residents might receive a card in their letterbox asking them to self-read the meter.
"The card provides instructions on how to do this, and doubles as a reply paid letter, which can be posted back to council without a stamp, she said.
