HUDDERSFIELD GPs have been put on alert after it was feared untreated water could have polluted the town's supply.
Tests have been carried out in the Holme Valley after Holmbridge treatment works was affected by a power cut.
The power surge last Thursday - which lasted several hours - interrupted vital cleaning processes at the plant on Brownhill Lane.
The water works supplies homes in Holme, Honley, Brockholes and Kirkheaton.
Today Huddersfield's health bosses confirmed they had been warned about the fault but said there had been no reports of infections as a result.
A spokeswoman for Huddersfield Central and South Huddersfield primary care trusts said: "There is viral gastroenteritis in the district which is usual for this time of year.
"But we have had no results from any local residents that would suggest they have an infection as a result of problems with the water supply."
She said Yorkshire Water - responsible for the works - had reported that some water had bypassed the full treatment process during the power cut.
But it was still chlorinated.
A spokesman for Yorkshire Water said: "We have been doing tests and taking samples and can confirm that it did not have any impact on what was going into the public supply.
"However, as a matter of course we always inform a number of different agencies."
He said the company was required to report faults to the Drinking Water Inspectorate, Environmental Health and the Health Protection Agency.
He added: "It seems the treatment process did not work but we managed to get it sorted by the time the water went out into the supply."
