"This is well short of our current demand requirements for this time of the year of 1100m3/hr," said Mr Koll.
"Important water stakeholders have been informed of the crisis and are implementing water restriction plans."
Mr Koll said there was no quick-fix to the problem. It could take two weeks before it was repaired, however, engineers and contractors were working on solutions.
While staff are sorting the problem, the council has imposed a ban on using hoses for non-essential water usage such as car washing, irrigation and filling of swimming pools.
"We also ask all other water users to conserve their water use as much as possible to avoid further water restrictions being imposed."
Updates will be posted on the council's website.
