Maintenance Considerations for Drip Irrigation Systems

Design Considerations for Subsurface Drip Irrigation (SDI) Systems

Gary A. Clark Research Irrigation Engineer Quick Facts Subsurface drip irrigation (SDI) is a low-pressure irrigation system that uses polyethylene driplines that are permanently buried below the soil surface. Water drips to the surrounding soil through built-in emitters (specialized small openings). SDI places water directly into the root zone of the crop. It may improve yield due to high appli...

Management Considerations for Operating a Subsurface Drip Irrigation (SDI) System

Gary A. Clark Research Agricultural Engineer Subsurface drip irrigation (SDI) systems deliver water to the root zone of crops using polyethylene drip tubing that is permanently buried below the soil surface. In properly designed and operated systems, little or no wetting of the soil surface occurs, nor is there visual evidence of the system performance. Because SDI systems apply water different...

Optimize Above–ground Drip Irrigation Systems for Small Areas

Drip irrigation systems offer the potential for efficient irrigation of high value crops and have proven feasible from engineering and agronomic standpoints in the northern Great Plains. However, little information is available in this region regarding the optimum design and economics of these systems. The objective of this study was to develop a computerized model for design and economic optim...

Condition Based Maintenance for Two-Component Systems with Reliability and Cost Considerations

This paper studies a maintenance policy for a system composed of two components, which are subject to continuous deterioration and consequently stochastic failure. The failure of each component results in the failure of the system. The components are inspected periodically and their deterioration degrees are monitored. The components can be maintained using different maintenance actions (repair...
