Sediment and detention basin drainage system and method

摘要

A fluid drainage system configured for draining a basin impounding fluid and sediment, solids or the like of varying density and turbidity. The system includes a first conduit and a second conduit within or adjacent to the first conduit to form a fluid receiving chamber between the first and second conduits, each conduit having apertures therethrough, with the apertures of the first and second conduits being sized and arranged relative to one another and so configured as to preferentially discharge fluid from the top of a basin, thus providing flow conditions which inhibit the entry of sediment into the system so as to maximize the retention of sediment within the basin and reduce turbidity and Total Suspended Sediment in the discharged fluid.

1. A hydraulic transistor comprising a fluid inflow device which receives a fluid and a fluid outflow device, a differential pressure head applied between a first fluid pressure head before the fluid inflow device and a second fluid pressure head between the fluid inflow device and the fluid outflow device causing a flow rate of the fluid inflow device to vary inversely proportional to the applied differential pressure head, wherein the fluid in flow device comprising a first vertical conduit and the fluid outflow device comprising a second vertical conduit within or subsequent to the first vertical conduit, the fluid outflow device being integral with or connected to a downstream outlet of the hydraulic transistor.
