Reeder/Garret/Johnson takeoff will be supplied by smaller pipe that will leave the main pipe <br />near the exit and continue north along 2700 Road to the existing distribution box. <br />Once mining moves west of 2700 Road and the area is restored to its approximate original <br />contour, the temporary line can be moved into the permanent location in the winter of 2004- <br />2005. The permanent pipeline will be ready for use in the irrigation season of 2005. <br />1. Design Details <br />1. The pipeline will be a continuous fused polyethylene pipe of 28 inch outside diameter <br />with no joints that will roll with the terrain. This pipe is the best choice for tough <br />applications and long term durability. <br />2. The pipe wall thickness of 1.33 inches is resistant to weather and wear and will remain <br />flexible. The polyethylene material is made to last indefinitely. <br />3. Other specifications: 80 psi rating (more than adequate), inside diameter 26.33 inches, <br />length of approximately 4000 feet. <br />4. The pipe has excellent flow characteristics and will handle 25 cfs during the 6 years of <br />temporary installation and will pass 38 cfs for the permanent location. All takeoffs for <br />irrigation in the permanent line will be based on a main pipe flow of 38 cfs. <br />5. Each takeoff will have a valve and weir for control and measurement of the outflow. <br />6. The pipe is extremely durable and will avoid many pitfalls of other pipe types. <br />7. The temporary pipe will be laid on the surface while the permanent pipe will be buried. <br />The permanent line will not interfere with any post -reclamation land uses. <br />8. A pressure regulator will be placed in the line near the exit to control flow in the entire <br />pipe. <br />9. During the temporary pipe time frame, the Reeder/Garret/Johnson distribution box will <br />be supplied from an 8" diameter SDR 26 pipe leading from the main pipe. <br />Section 2.05.3(3) Page 44 February 2017 (TR -78) <br />
