Testing of the Lindfield Park Road fire ground is showing the rehydration plan using reclaimed water is proving effective.
Already some 20 megalitres of water has been piped onto the peat moss fire.
The joint operation is between Port Macquarie-Hastings Council, the Rural Fire Service, Environment Protection Authority, department of planning, industry and environment and NSW Health.
There were several health warnings raised regarding smoke and impacts on residents' health including from air quality concerns.
Continued monitoring of air quality affected by smoke from the Lindfield Park Road bushfire, private burn offs and domestic fireplaces is indicating readings ranging between fair and very poor in the Port Macquarie area.
The use of reclaimed water to combat the bush fire is a first.
The Environment Protection Authority (EPA) described the use of the reclaimed water as "appropriate", according to a spokesperson.
"The EPA is satisfied with the use of reclaimed water on the Lindfield Park Road peat moss fire," the spokesperson said.
"We anticipate the operation to continue for a further two months.
"Using reclaimed water is an appropriate solution given the ongoing drought conditions in the area.
"Testing to monitor the depth of the water recharge is being undertaken by the department of planning, industry and environment (DPIE) and will continue until the fire is extinguished."
The department of primary industry and environment was also supportive of the rehydration program. The DPI and Port Macquarie-Hastings Council were contacted for comment.
The RFS says it is not aware of a similar use of reclaimed water to extinguish a fire.
"The "rehydration" process is unique is so far as the use of reclaimed water, a spokesperson said.
"We are not aware of reclaimed water being used for such purchase previously
"Of the 30 megalitres of water planned to be used about 20 megalitres - as of last Thursday evening - had so far been used on the fire ground."
The spokesperson said no two peat fires are the same and each peat fire is assessed on it unique conditions.
