Residents in Chorley were left without running water for two days because of a broken water pump.
Around 19 people living in Gillibrand House in Lancaster Court had no means of showering, washing their hands or flushing their toilets as a result.
The housing association which oversees the homes, Places for People, has confirmed that the water supply has been back on since 10am this morning.
Residents Denise Hartley and Lynn-Marie Williams had contacted the Guardian today individually fearing that they would find themselves without water over the weekend.
Denise said: "Eventually last night United Utilities delivered some bottled water so at least we could get a drink."
A spokesperson for Places for People said: “We understand the frustration our customers have felt during this brief time without running water and apologise for any inconvenience.
"We worked closely with United Utilities and our specialist contractors to fix the problem, which was caused by a split in the water pump.
"Residents were provided with bottled water as soon as the mains supply was switched off.
"The specialist parts needed to complete the repairs are due to be fitted on Monday.
"A temporary fix was put in place on Thursday and following testing, has allowed the water to be switched back on this morning.”
If any residents are concerned or experience any problems they are advised to contact Places for People’s 24 hour customer service team on 0845 850 9571 or 01772 667002.
