Northern Ireland Water has been fined £1,000 for allowing untreated sewage to spill into a Co Down river.
The source of the discharge into a tributary of the Enler River was traced to Moneyreagh wastewater treatment works, a DoE spokesman told Newtownards Magistrates Court.
In a statement, the DoE said a water quality inspector noticed extensive sewage fungus growing on the bed of the waterway and traced the pollution back to the treatment works.
“The inspector revisited the treatment works on January 16 2009 and observed that the storm tank was full and that untreated sewage was discharging from the outlet overflow weir,” a spokesman said.
“A further visit was made on April 17, 2009 when it was observed that the storm tank was full and overflowing.
“A sample confirmed that the discharge contained poisonous, noxious or polluting matter which was potentially harmful to fish life in the waterway.”
After NI Water pleaded guilty, a spokesperson said the pollution incident was linked to an underlying problem with capacity to treat all the flows to the treatment works.
