Incidents of flytipping in England have fallen by 9% this year, according to the latest figures.
Defra has reported that local authorities dealt with over 744,000 flytipping incidents in 2011/12, compared to 2010/11.
Official analysis indicates that nearly two thirds of fly-tips involved household waste and most were loads from a small van or less.
The estimated cost of clearance to local authorities was £37.4m, again about 9% down on the previous year.
The number of enforcement actions by councils was down 14% year-on-year: 490,000 cases cost a total of £17.6m. There were nearly 2,800 prosecutions, of which 99.6% resulted in a conviction.
The ability of local authorities to use surveillance cameras to identify flytippers under the Protection of Freedoms Act 2012 was raised in a Parliamentary question from Liberal Democrat MP Sir Bob Russell.
Communities secretary Eric Pickles said permitted surveillance was restricted to serious crimes and required a warrant. But Pickles said a council could apply for a warrant to install a surveillance camera to try to catch flytippers.
