PRIVATE home pool owners are required to register their pools online by October 29.
Failure to do so could result in a $220 fine and the possibility of a maximum court-imposed fine of $2200.
Under new pool safety laws, it is mandatory for pool owners to register and check their compliance online.
As part of the self-assessment, owners must determine whether their fencing complies with new legislation.
The legislative changes were introduced in 2009 after a comprehensive review into the high non-compliance rate of pool gates and continuing incidents of preventable drowning.
In the past year, one Liverpool child was the victim of preventable drowning.
Liverpool Council will be required to implement an inspection program under the new laws, with mandatory inspections of tourist, visitor and multi-occupancy developments to start in April next year.
The council will charge an inspection fee of up to $150 for the first visit and $100 for re-inspection.
Cecil Park resident and pool owner Sonia Lopreiato said she was angered at the fee amount, claiming it was just another way for the government to make money.
"We are now being punished with fees just because we own a pool," she said.
"I've had my pool for more than 15 years and we've never had a drowning. Why are they enforcing this now?
"Kids can drown in a bathtub if they are left unattended.
"If they really care about children's safety, they wouldn't worry about charging people a fee. They would do it for free."
The 41-year-old said she would rather complete a first-aid course than upgrade the safety of her pool.
She said she it could cost her and others more than $500 in fines if their pool doesn't comply.
"And that makes me angry," she said.
There are about 7500 known pools in the local government area, which a council report states could generate an estimated $200,000 a year for council coffers.
But Liverpool Council general manager Farooq Portelli said it was more likely that the council would incur additional costs by implementing the inspection program and the estimated revenue would not cover the full costs of delivering the service.
"At this stage, inspections for residential properties will only be on request or in response to a complaint," he said.
"Swimming pool compliance certificates are only mandatory when a domestic property, tourist, visitor and multi-occupancy development is sold or leased from April 29 next year.
"While the council understands there might be an additional cost for residents, pool safety and the prevention of child drowning is paramount."
