Box 856 Warsaw, NC 28398 Phone: (910) 293-3434 Required Documentation The following details of design and Materials must accompany all irrigation designs: • 1. A"scale drawing,.of the proposed irrigation system which" includes hydrant locations, pipelines, thrust.biock locations and buffer areas where applicable.. 2. Assumptions and computations for determining total. dynamic' head and horsepower requirements. 3. Computations used to determine all mainline andlateral•pipe sizes. 4. Sources and/or calculations used for determining application rates. 5. Computations used to determine the size of thrust blocks and illustrations of all thrust block configurations required in the system 6. .Manufacturer'sspecifications for the irrigation pump, traveler and sprinkler(s). 7. Manufacturer's specifications'for the irrigation pipe and/or USDA-NRCS.standard for IRRIGATION'WATER CONVEYANCE. 8. The information required by this form are the minimum requirements. It is the responsibility of the designer to considerall relevant factors at a particular site and address them as appropriate. - .9. Irrigation pipes should not be installed in, lagoon or storage pond embankments without the approval of the designer. NOTE: A buffer strip of 25' or wider must bemaintained between the limits of the irrigation system and all perennial streams and surface waters per NC Statutes. Sheet6 •.Narrative of Irrigation System Operation This design dated 11/4/2020 is for an addition of pulls and a "wetted acreage" determinationfor an existing. facility. The acres were calculatedbased on, the equipment specified and the charts created by NCSU for calculating Area Allowances for Hard Hose Traveler Systems. This irrigation system is designed to use 6".above-ground aluminum pipe and the two existing 6" hydrants.. The system is designed to accommodate the flow velocities, .flow -rates and pressure requirements associated with an Ocmis R211 traveler with 1150' hose: The design -of the traveler system requires the use of a 0.87 nozzle in the gun. Each pull has a specific arc setting and: travel speed which must be usedto achieve.the desired application This information is given in. Table 2 of this design. A detail of the pull layout is also included: Referto owner's manual and irrigation dealer for informationon_maintenance, winterization, and operation of system.
