摘要

The catchment reservoir acting as a street or pavement waste material receptacle comprises a concrete housing (2) with at least one vertical wall (3), on which is a cast iron outlet piece (4) with a virtually flat wall part (5), and a connecting stub piece (6,9). The outlet piece has a connecting stub with the greatest diameter. The outlet piece is rendered suitable for connection to it of pipes with the smallest diameter. The outlet piece comprises a single cast piece and concentrically within the greatest connecting stump a smaller connecting stump (9) is fitted, which is connected with the greatest connecting stump by an outwardly connected edge.
