摘要

The water build up basin is esp. for the main connection in mixed water sewerage. It has a base enclosed by side walls with a feed opening and a deeper outlet opening. The pipeline passing to the feed opening runs in the extension of a top side wall which extends along a top base edge. The basin base (1) is in the form of a sloping plane with a drop, whose direction with the in-flow direction includes a max. angle of 90 deg. There is a drain channel (16) inclined to the drain hole (22) along a bottom base-side edge.
