1.5 million bill for cleaning up after Haringey's fly tippers

The Tottenham Journal reports that it cost the borough 1.5. MILLION to clean up after the borough's fly tippers. They compare this with Camden and Islington -

In comparison, Islington had just 2,634 reports of flytipping, while Camden had 10,950, costing the boroughs £101,706 and £229,852 respectively to sort out.

Anecdotally, tales of being told by neighbours and fly tippers that its "all right" when they fly tip because the "council will clear it up" demonstrate that there is a gap in people's understanding here as they seem to (want) to believe that this behaviour comes without a cost to the community. 

£1.5 million is a lot of money to spend so the questions that spring to mind are how can people in this borough be taught to see the financial cost to the community of their fly tipping behaviour? Why is it worse here than in Camden and Islington - have they done anything different from which we can learn? Or are there circumstances peculiar to the borough that need a specific solution?

As ever when I see this kind of figure I have to ask WHY? What is driving the mind set that tells itself "it's all right, the council will clear it up" and how to we change that mind set for good?
