Abstract
System for drainage of surface water, the system comprises a number of tanks being connected to a main pipeline leading water to a recipient. Each tank has at least one outlet for leading water from the tank to the main pipeline, and a corresponding lid, the lid is limiting the outlet until the water is at a predetermined level in the tank. The system further comprises a check valve arranged downstream of the outlet of each tank, preventing water from entering the tank from the main pipeline, and at least one air bleeder valve and at least one siphonic drainage regulator arranged between a tank and the recipient.

A system for drainage of surface water, the system, comprising:
- a plurality of manholes connected to a main pipeline for providing water to a recipient, each manhole having at least one outlet for leading water from the manhole to the main pipeline, the at least one outlet comprising a corresponding lid for limiting the outlet until water is at a predetermined level within the manhole, wherein
- a check valve is arranged on a pipeline connected to the at least one outlet of the manhole downstream of the outlet of the respective outlet for preventing water from entering the manhole from the main pipeline,
- the pipeline is arranged as an inverted U-shaped pipeline within a manhole downstream of the outlet, and
- at least one air bleeder valve is arranged on the inverted U-shaped pipeline, the bleeder valve configured to let air out from the inverted U-shaped pipeline while preventing air from entering into the U-shaped pipeline.
Use of a system for draining surface water, wherein the system comprises:
- a plurality of manholes connected to a main pipeline for providing water to a recipient, each manhole having at least one outlet for leading water from the manhole to the main pipeline, the at least one outlet comprising a corresponding lid for limiting the outlet until water is at a predetermined level within the manhole, wherein
- a check valve is arranged on a pipeline connected to the at least one outlet of the manhole downstream of the outlet of the respective outlet for preventing water from entering the manhole from the main pipeline,
- the pipeline is arranged as an inverted U-shaped pipeline within a manhole downstream of the outlet, and
- at least one air bleeder valve is arranged on the inverted U-shaped pipeline, the bleeder valve configured to let air out from the inverted U-shaped pipeline while preventing air from entering into the U-shaped pipeline.
