Abstract: Aspects of a detention pond retrofit device for detention basin outlet control provide structures designed to throttle stormwater flow and maintain the rate at which water is discharged from the system below Qcritical, the flow rate at which erosion and down cutting of the receiving stream would begin, based on channel morphology and bed material resistance. The primary goal of the device is to induce increased flow detention during low to moderate rain events, while providing similar hydraulic performance during large events to that of the detention basin performance prior to the installation of the retrofit unit. This is achieved through a “T” or “Y” design with split flow paths, in which the lower path is hydraulically restricted through the installation of structures while the upper path is unrestricted.

Abstract: A method lays lined pipeline which actively and successfully removes air pockets which might be trapped in the annulus between the liner and the host pipe by progressively flooding the lined pipeline. Further, the liner is brought into closer contact and engagement with the host pipe. The removal of air in the annulus enables the pipeline test pressure to stabilize more quickly and avoids the risk of potential collapse during operational service life in the event the pipeline pressures fluctuate or a vacuum is created during an emergency shutdown.
