Dirty water caused quite a stir in Raglan St, Masterton, yesterday.
Resident Frank O'Cain was contacted by a neighbour, who was about to bathe his grandchildren, and warned that the water was discoloured.
Mr O'Cain said he was frustrated the council had failed to advise residents their water would be affected by work in the area.
"They didn't give us any warning," he said. "Why didn't they drop a note in?"
His wife, Margaret, had put a load of white delicates on to wash, after finishing her voluntary shift at the hospital, and discovered they had been stained.
