摘要
A sewerage system comprises in addition to straight pipes - mainly bent pieces (24, 13, 14) wherein the cleaning holes (3) or cleaning tubes (4) of a private sewer (8), the service connection (6) with a bent piece (7), and the collecting or service main (5) are unified into a single universal cleaning hole or universal cleaning tube located advantageously e.g. in the park area instead of being located on the road (9) which enables unimpeded, easy cleaning of the sewerage system by means of cleaning machines. Also disclosed is a cover especially for the above sewerage system, wherein in addition to the bearing surfaces due to its recessed position, the cover (17) has a further bearing surface (23) supported at one or more points and the cover (17) is contained in a combined cover (16) having a rubber ring (18) sealing at its lower end executed as a spigot- and-socket joint.
