WERRIS Creek residents have been urged to avoid using town water where possible after major flooding washed away critical water pipes.
Friday night's storm has damaged the train tracks, washed away parts of roads along with the pipeline that connects Quipolly Dam to the town's water treatment plant.
On Sunday morning, Liverpool Plains Shire Council issued an urgent water warning, urging residents to stop using water unless it was drinking or flushing toilets.
The council enforced Level 5 water restrictions immediately, with repairs under way.
Australian Community Media (ACM) has been told crews are on scene at the pipeline trying to repair and restore services after the dam to treatment plant pipe was damaged.
"Please limit water usage to drinking and flushing toilets only. Do not hose down the debris until the repairs are made," council said in the warning to residents.
Crews are stretched trying to get to the damage scattered across town that has seen roads and walkway bridges washed away.
Major flooding impacted parts of the town after Friday night's torrential downpour that saw more than 120mm recorded in the area in just a few hours.
Flooding stops trains on tracks
The Sydney-to-Moree and Armidale train services have stopped.
Tracks have been flooded on the outskirts of Werris Creek and crews are again on scene on Sunday trying to repair the damage.
Train services were stopped on Saturday and were not operating again on Sunday.
Transport NSW said train services were stopped at Muswellbrook and buses would replace the service to and from Muswellbrook for any Moree, Tamworth and Armidale passengers.
Delays are expected.
"At Muswellbrook passengers will transfer to a road coach service for the remainder of their journey. Some delays are anticipated," the travel alert said.
"NSW TrainLink apologises for the inconvenience."
The Gap Road is the only road that remains closed on Sunday morning, with the water levels and damage still to unsafe for motorists.
Telstra phoneline services have also been restored after they were cut off for about 24 hours.
Landlines and internet outages were reported, but crews managed to restore the services to locals.
Wild weather shuts roads, cancels events
The council is urging locals to be patient with crews trying to get to all jobs.
The Australia Day activities planned for Werris Creek on Sunday afternoon have also been cancelled, the council has advised.
On Saturday, the SES said it had been a huge week for local crews who had been slammed with jobs across the Namoi region.
On Saturday night, flooding closed several roads in Tamworth, Werris Creek and Wallabadah.
The New England Highway was closed at both Willow Tree and Wallabadah because of water and debris across the road.
It reopened within hours.
There was also water across Appleby Lane and Goddard Lane in Tamworth on Saturday night, while The Gap Road was still closed on Sunday because of the water levels, damaged guard rails and the debris still stuck on the roadway.
In the early hours of Saturday morning, two men and six dogs had to be rescued from a flooded causeway after their car and trailer was washed off the road in the Caroona/Spring Ridge area.
About 2am, SES, the VRA, police and paramedics were called to Coonabarabran Road after the stationwagon, with two men and six greyhounds rescued without injury.
SES call outs surpass 100 jobs
On Saturday, the SES confirmed it has received 38 calls for help across the Namoi zone after Friday night's huge storm.
In the Liverpool Plains area, there were 14 calls for assistance including for a car floating down the street, and several houses flooded in the Werris Creek area.
No one was trapped, and no one was injured.
In Tamworth, SES crews had nine call outs for help for jobs like sandbagging homes, trees down and roof damage from the storm.
A spokesperson for the SES said crews helped to sandbag homes, repair damaged roofs, and help after homes were inundated.
The New England SES Deputy Zone Commander Katrina Miegel said crews had had 122 call outs for help across the zone for the week.
Ms Miegel said crews had been called to assist after roofs had been blown off houses and felled trees.
The SES also helped with animal rescues, flooded housed; damaged windows damaged, road crash rescues, as well as flood rescues.
She said the callouts had included jobs in Tamworth, Werris Creek, Quirindi, Caroona Manilla, Tingha, Inverell, Armidale, Wee Waa, Gunnedah, Tenterfield, Narrabri, Moree and Walcha.
"This is on top of months of support work to our fellow RFS, fulfilling incident management roles where many volunteers have assisted in logistics, catering and delivery of supplies," she said.
"This is just a snapshot of the great work that the volunteers train so hard for, so that they can help the community when needed."
But there might not be any rest with more wild weather and severe thunderstorms expected to hit the region on Sunday and into the start of the week.
