The Mount Isa Water Board says it is waiting on replacement parts from Brisbane to fix the problem that caused a critical failure in water supply on Friday.
MIWB Chief Executive Stephen Farrelly said overnight Thursday an incident damaged electrical infrastructure necessary for the filtration process.
"There is sufficient water available for all essential uses for the present time," Mr Farrelly said.
"Full restoration of the treatment capacity is pending the arrival of replacement parts from Brisbane, however the team has made excellent progress today (Friday) in completing partial repairs which will limit any risk of water running low next week.
"We thank the community for their co-operation with the precautionary water conservation measures over the weekend."
Earlier Mount Isa City Council had urged residents to conserve water after MIWB slashed their daily allocation from 20 to 15 megalitres.
Council has now stopped park and public space irrigation and are looking at measures to conserve water throughout all council services and residents may experience a reduction in water flow outside of peak hours to assist with the conservation efforts.
"We urge the community to please reduce water consumption and conserve water wherever possible throughout the weekend, and until the services can be fully restored," Council said.
Mount Isa Water Board apologised for any inconvenience caused by the request to reduce water use.
"I want to assure the community that all actions are being taken to avoid any interruption of residential water supplies," Mr Farrelly said.
"Supply of unfiltered water to the Mine remains unaffected."
