Sewer blockage caused by screwdriver and rags
Flooding from a sewer was caused by someone putting a screwdriver and a ball of rags down the drain.
The firm's interim director of operations, David Dangerfield, said: "Blockages can have a dramatic impact not only on individual customers, but also on the environment and community.
"We're playing an active role in educating the public on the benefits of disposing of their waste in a bin.
"This will help improve the efficiency of the drainage system as well as safeguarding the environment.
"Our sewerage system was only designed to cope with human waste and small volumes of toilet roll.
"Other items such as cotton buds, nappies, tampons and baby wipes which people flush down the toilet do not break up and usually clump together to form a ball of rags."
Mr Dangerfield said NI water was continuing to run its Bag It and Bin Itcampaign to educate the public on the dangers of flushing inappropriate items down the toilet.
