Abstract
In an inverted siphon (4) in a sewer (1, 1a) where the approaching flow of sewage is insufficient for producing self-rinsing, a fluid reservoir (5) is arranged upstream of the inverted siphon which has sufficient volume for effecting rinsing, and the fluid content of the reservoir intermittently by means of driving members (6, 8, 9) is emptied through the inverted siphon at a velocity which corresponds to and at least during a certain time exceeds the required rinsing velocity.
Claims10
A method for effecting rinsing of an inverted siphon which forms part of a sewer by interconnecting two separated sections of a sewer line comprising, arranging upstream of the inverted siphon a fluid reservoir having a volume which at least corresponds to the volume of the siphon for the length thereof requiring rinsing, and at least once every twenty-four hours applying a jet force in said siphon to cause the fluid contents of the reservoir to flow through the inverted siphon with a flow velocity which at least corresponds to the rinsing velocity required for removing sludge which has accumulated in the inverted siphon.
In a sewer system having an inverted siphon between two conduit sections, a device for rinsing the inverted siphoncomprising one of said conduit sections, a fluid reservoir arranged upstream of the inverted siphon having a reservoir volume at least corresponding to the volume of the siphon for the length thereof requiring rinsing and means adapted to cause the contents of the fluid reservoir to be emptied through the inverted siphon at predetermined intervals and at a velocity at least corresponding to the required rinsing velocity to remove any sludge accumulated in the inverted siphon and discharged it through the other conduit.
