In this talk the class of multi-fields reductions of the KP and super-KP hierarchies (leading to non-purely differential Lax operators) is revisited from the point of view of coset construction. This means in particular that all the Hamiltonian densities of the infinite tower belong to a coset algebra of a given Poisson brackets structure.
