The present invention addresses this by providing a drainage system (1) comprising:
- a reservoir (2), having an inlet opening and at least one outlet opening (11),
- a flap gate (4) arranged on the inner side of the reservoir (2) capable of covering the inlet opening, when the flap gate (4) is arranged in a closed position, and when the flap gate is in an open position, water is capable of running into the reservoir,
- at least one gate valve arranged relative to said at least one outlet opening (11), such that said at least one gate valve is capable of covering said at least one outlet opening, when the gate valve is arranged in a closed position, and when the gate valve is in an open position, water is capable of running out of the reservoir through the at least one outlet opening,
- at least one outlet pipe (6) having a first end opening and a second end opening, wherein the first end opening is arranged in fluid connection to the at least one outlet opening (11) in the reservoir (2),
- a flush gate (7) arranged relative to said at least one outlet pipe's (6) second end opening where the flush gate (7) is capable of covering said second end opening, when the flush gate is arranged in a closed position, and when the flush gate is in an open position, water is capable of running out of the at least one outlet pipe 's second end opening.
