Waterford City and County Council took the case when inspectors discovered that the farmer had dumped waste from a septic tank he had emptied into a stream on his land.
The farmer pled guilty to the offence at the earliest opportunity.
The incident was also cross reported to the Department of Agriculture, Food and the Marine, which resulted in the farmer being penalised 20% of his farm payments.
Septic tank owners are reminded on the requirement to use an authorised waste collector to empty their septic tanks.
Always ask to see a copy of their permit or check it at the National Waste Collection Permit Office at www.nwcpo.ie
