Businesses and households in the area were affected by the problem on Saturday.
Scottish Water confirmed on Sunday it has resolved the issue as normal supply to the town’s water network via the repaired main was resumed overnight.
Engineers have since been monitoring the recovery of the local network.
On Saturday afternoon and evening, teams from Scottish Water worked to restore and sustain water supplies for around 2000 homes and businesses that had initially experienced disruption. Water was re-routed through unaffected parts of the network and a fleet of tankers brought extra supplies into the area by road.
A spokesman for Scottish Water said: “We are sorry for the significant disruption that customers in Denny experienced to their water supply on Saturday, resulting from a secondary burst which required a challenging repair.
“Our initial focus yesterday was to restore supply via the water network to all affected customers as quickly as possible, while providing additional support to those who needed it.
“Our team on site then worked into the night to complete a challenging repair, so that we could recharge the trunk main and restore normal service. We would like to thank customers for their patience while this work took place.”
Following the return to normal operation, some customers may experience discoloured or cloudy water. If this occurs, they are advised to run their cold kitchen tap at half pressure until the water runs clear.
