"It will not be until at least early next week before the pump will be brought back into service," Mr Cawte said.
"The standby bore and pump has been coping well with the reduced demand, and the rain several days ago really reduced demand even further so we managed to fill the reservoir yesterday."
However, because somebody vandalised a shed and managed to shut a valve feeding water to the reservoir 40 per cent of the storage water was lost this morning, before flow was restored to the reservoir.
Mr Cawte said it was exactly the wrong time fore this to happen.
"Needless to say, very disappointing news for us this morning. We have arranged for several tanker loads of water today into the reservoir to restore some of the storage lost," said Mr Cawte.
The council are asking residents to keep conserving water and if anyone has any information about who might have vandalised the shed, please contact the police on (07) 3480099
