GWMWater’s Andrew Rose said there was a problem with the main pipeline from Halls Gap to Pomonal and crews could not get into the area to repair it.
“We are aware there are some residents who have chosen not to evacuate and we have referred the matter to the Incident Control Centre in Horsham and they will be in touch with those people,” he said.
“We don’t know what has caused it but the pipeline is about a kilometre long and where don’t know where the fault is, and it is far too dangerous to go in and fix it.”
Mr Rose said he did not know when crews might be able to get to the pipeline to repair it.

Towns in the Grampians are currently facing the most severe bushfire conditions, with the expected cool change coming through on Friday afternoon. Intense wind fire conditions have been created, which is making the task of controlling the 32,000 hectare fire even harder.
The fire has already burnt much of nearby Wartook Valley.
Residents have been told it is too late to leave and to take shelter immediately.
Kookaburra Motor Lodge owner Stephen Odgers told Fairfax Media he chose to stay and defend his Halls Gap business. Just before 5pm, Mr Odgers said it appeared the town had been spared, for now.
He said the air was thick with smoke and could see the glow in the horizon.
‘‘It doesn’t look too good towards some other parts. The helicopters have been filing up water,’’ he said.

Staff did not have to evacuate the Halls Gap zoo depsite a CFA order being issued earlier on Friday and the animals remained safe.
Zoo owner Greg Culell said in the worst-case scenario staff had been prepared to evacuate to a dam on the property and that the animals were never abandoned.
With the cool change, a warm south-westerly wind created chaotic conditions for the CFA.
The intensity of the blaze is creating its own microclimate, with lighting and storms now occurring.
Erratic wind conditions, including gusts, have been created and are a point of concern for the CFA if the bushfire spreads any further.
A CFA spokeswoman said 621 firefighters are at the scene and are supported by 88 trucks and eight bulldozers.

"Predicting what's happening is fraught. We are not able to say when you can return," he said.
“When the wind comes through it is really going to swing around towards Halls Gap,” CFA media officer Melissa Douglas said.
Emergency text messages are also being sent to those in the area, although the CFA said not all of them are getting through because of “reception difficulties”.
Ms Douglas said police would direct residents and visitors to the safest route to evacuate the town.
Police have been travelling to homes and business around Halls Gap, telling people they should leave.
More than 40,000 hectares have been burnt in the state’s north-west region, with no relief in sight for fire-fighters hoping to contain the blaze. Several out-of-control bushfires across Mallee could get worse thanks to Friday afternoon’s wind change.

Nine aircraft are supporting about 250 firefighters in the battle to control the blazes occurring mainly in parkland and reserves.
