IRRIGATION PIPELINE (Ft.) 430 A pipeline and appurtenances installed to convey water for storage or application, as part of an irrigation water system. This practice may be applied as part of a resource management system to achieve one or more of the following purposes: Conveyance of water from a source of supply to an irrigation system or storage reservoir. Reduce energy use. Develop renewable energy systems (i.e., in-pipe hydropower). This standard applies to water conveyance and distribution pipelines installed above or below ground. This standard does not apply to multiple outlet irrigation system components (e.g., surface gated pipes, sprinkler lines, or micro irrigation tubing). General Criteria Applicable to All Purposes The installation and operation of this practice shall comply with all federal, state and local laws, rules, and regulations. All permitting authorities such as Tennessee Department of Environment and Conservation (TDEC), U.S. Army Corps of Engineers (USACE), Tennessee Valley Authority (TVA), etc. shall be consulted or polices reviewed in order to check requirements for permit coverage (i.e. TDEC-ARAP, USACE 404, TVA 26a). The water supply, quality, and rate of irrigation delivery for the area served by the pipeline shall be sufficient to make irrigation practical and feasible, for the crops to be grown and the irrigation water application methods to be used. Pipelines shall be placed only in soils and environmental conditions suitable for the material type being selected. Pipelines shall be designed to meet all service requirements such that internal pressure, including hydraulic transients or static pressure at any point is less than the pressure rating of the pipe. Capacity. Capacity shall be sufficient to convey the design delivery flow rate for the planned conservation practices. Design capacity of the pipeline conveyance or distribution system for irrigation systems shall be sufficient to meet the requirements for efficient application based on one of the following: Adequate to meet the moisture demands of all crops to be irrigated in the design area. Sufficient to meet the requirements of selected irrigation events during critical crop growth periods when less than full irrigation is planned. For special-purpose irrigation systems, sufficient to apply a specified amount of
