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 method 200 for priming a drainage apparatus 100 comprises directing liquid into the conduit arrangement at 202 via the liquid injection inlet 106b12 to fill up most of the conduit arrangement as controlled by the valves' configuration; directing liquid into the first reservoir 102 at 206 to enable more liquid to enter into the conduit arrangement via the first opening 112 and at 208, to flood the conduit arrangement to form a continuous liquid flow path which extends from the first opening 112 up to at least the second opening 114, the continuous liquid flow path creating a siphon; and with the first opening 112 kept below the liquid's surface level in the first reservoir 102, stopping the flow of liquid into the first reservoir 102 to achieve a state of equilibrium of the siphon at 210 to prime the conduit arrangement.

The disclosure discloses an integrated riparian system for river/lake silt on-site treatment and application thereof, belonging to the technical field of silt treatment. The integrated riparian system includes three subsystems, namely a silt ecological treatment subsystem, a siphon drainage subsystem and a silt leachate advanced treatment subsystem. The silt ecological treatment subsystem is provided with plants, fillers, an aeration pipe and a water collection pipe from top to bottom, and a vent pipe is connected to the water collection pipe. A siphon in the siphon drainage subsystem is retractable and hump-shaped. The silt leachate advanced treatment subsystem includes a first-stage ecological treatment unit upflow wetland and a second-stage ecological treatment unit surface flow wetland. According to the disclosure, dewatering and harmlessness of silt, advanced treatment of silt leachate and purification of part of river/lake water are effectively realized through transpiration and absorption of the plants, filtration and adsorption of the fillers and degradation of microorganisms.
