Y--Leavenworth Fish Hatchery SWISP Phase II

The Leavenworth National Fish Hatchery Surface Water Intake Fish Screens and Fish Passage Project, Phase II, involves the rehabilitation of a pipeline. The project includes the installation of HDPE pressure pipe, concrete thrust restraint blocking, and other related work. The contractor will be responsible for flushing, filling, and testing the pipe, as well as performing quality control tests. The project requires compliance with various standards and regulations, including ASTM and ACI standards. The contractor must also ensure that the pipe is properly bedded and embedded, and that the backfill is done in accordance with the specifications. • The project involves the installation of approximately 1,768 linear feet of HDPE pressure pipe. • The contractor must perform fusion quality testing on the HDPE pressure pipe. • The project requires the use of a pre-placed aggregate and a controlled low strength material (CLSM) for pipe bedding and embedment. • The contractor must ensure that the pipe is properly flushed and filled before testing. • The project involves the use of a tracer wire system to locate leaks in the pipe.
