More than one million incidents of fly-tipping were dealt with by councils in England in 2016-17, costing taxpayers £58m to clear up.
It was the fourth year in a row that incidents increased.
About 56,000 fixed penalty notices were handed out by councils to people caught illegally dumping.
The Department for the Environment, Food and Rural Affairs (Defra) said two-thirds of fly-tipping was household waste.
There were about 1,002,000 cases of fly-tipping handled by councils in England between April 2016 and March 2017, equivalent to 114 every hour.
This was 66,000 (7%) more than the year before.
