Where would you construct a garbage dump in your constituency?

Sometime back I wondered in A billion-dollar question about the decision-framework of a corporation to locate its production site in a "flat" world. The political context of the question is even more interesting.

Suppose you are the MP of a constituency and you have to construct a garbage dump. Where would you construct it?

Garbage dumps are an example of the Not-In-My-Back-Yard or NIMBY allocation. Is it only a coincidence that most garbage dumps in cities are located near slums or public places?

There is a way to circumvent the above problem. But I must incubate it first.
