Porirua water is leaving a bad taste in residents' mouths.
Aotea resident Annette Flett said she noticed her water tasted strange last week.
"You could taste it straight away. It tasted like you had added a bit of dirt to your water," she said.
She thought it was caused by a burst pipe on the street, but after talking to her sister realised it was a widespread problem.
"I assumed that because we had three weeks of rain the reservoir had unsettled."
Flett considered buying a water filter after she became concerned for her family's safety.
"Every time I drink it I'm thinking, 'I hope this is safe'. It really tastes like you're drinking dirt."
Flett said the water had not tasted that way in the five years her family had lived in Aotea and she was concerned how long it would last.
Wellington Regional Council water marketing adviser Andrew Samuel said the taste was caused by a change in the water supply, but said it was safe to drink.
He said the regional council had to switch to using a storage lake because of heavy rainfall stirring up the usual river supply.
An organic compound found in the storage lakes could cause an earthy taste and smell, Samuel said.
He said the water supply had been moved back to the rivers and the dirt taste should be gone shortly.
