Dumping the waste they had each been planning to drop off at the tip, cost two Sunderland residents dear after they were both issued with £350 fixed penalty notices.
In the first case, after arriving at the household waste reception site in Beach Street to find a queue rather than wait, a Millfield resident chose to dump a load of carpets down by the riverside near The Ropery .
In the second, the boyfriend of a Grindon resident dumped a load of black bags in a wooded area off Ropery Road after getting to the tip after it had closed.
After noticing one of the bags had begun spilling into his car, rather than taking the rubbish back home, he drove the car to an area nearby and decided to dump it instead.
Councillor Amy Wilson, Portfolio Holder for Environment and Transport, said: "Our Beach Street Household Waste site is open from 8am until 8pm, seven days a week between April and September and from 8am until 5pm on weekdays and until 6pm at weekends the rest of the year.
"In fact the only two days it closes are Christmas Day and New Year's Day, so there really is no excuse for people thinking it's ok to dump their rubbish rather than taking it to the tip another time.
"Fortunately the vast majority of our residents dispose of their waste responsibly but there are always a few who think it is acceptable to blight their community. We can and will take action when these cases come to light."
