\noindent {\bf Abstract:} 
Constructing preconditioners for the diffusion equation in highly 
heterogeneous media is a complex task. In this presentation, we will show one
approach to construct a multilevel preconditioner for such media. 
The equation is discretized using the finite volume method. The 
constructed preconditioner is spectrally equivalent to the original 
matrix. Numerical results will be presented.
