A number of homes around Ipswich have woken up to brown or yellow water coming from their taps.
Homes in Kesgrave and surrounding villages have been effected by the discoloured water.
Last month people in Ipswich also woke up to brown water coming from their taps.
A statement on Anglian Water's website reads: "We're really sorry but some customers in Kesgrave may be experiencing brown, orange or yellow discoloured water due to to a disturbance of iron sediments in the water main.
"Iron in the water is harmless and is usually short-lived but we are carrying out localised flushing to remove the discolouration."
