Assess site-specific buried drip design, preserve access and an installed map, measure commissioning performance, and plan monitoring and maintenance.
Record crops, root patterns, soil layers, slopes, water source, field operations and access needs. Discuss the proposed system with an irrigation designer, including germination needs, drainage, maintenance and the consequences of an inaccessible line failure.
Obtain a plan with product-specific burial depth, spacing, hydraulic calculations, filtration, pressure control, air/vacuum protection and flush access. Review water-quality evidence and how the system will be monitored and repaired. Compare the design’s emitter inventory with the planned zone flow.
Arrange utility location and installation by suitable operators. Record actual line routes, depth, joints, access points and protective setbacks before covering. Verify accessible flushing and isolation points and keep a clear map for later cultivation or repair.
Follow the system commissioning procedure, including flushing, leak checks and pressure/flow measurements at designed test points. Compare accessible representative discharge measurements and zone meter use with the specified performance. Confirm root-zone wetting with the crop/soil monitoring method.
Track water use, pressure, crop response and filter service using the baseline method. Use the installed map before tillage or excavation. Investigate changes in delivery or wetting before increasing runtime; arrange supported maintenance or repair and update the map after any work.
Keep the site assessment, crop operations and questions for the designer. · Save the as-built line map, component identifiers and installation changes. · Record commissioned zone flow/pressure and root-zone observations against the design criteria. · Keep performance trends, maintenance actions, repaired locations and the next inspection trigger.
Cross-check nominal flow for equal-rated emitter groups; use the designer’s hydraulic plan for all pressure and layout decisions. · Use equal-duration emitter collections where accessible and appropriate; keep the sampling limits explicit.

K-State describes SDI design as depending on crop, soil, topography, field configuration and supply. Burial depth and spacing must fit the actual design and field operations.
A nominal flow total checks the specified emitter inventory. Accessible pressure and timed flow measurements provide a separate commissioning record, with its sampling limitations.
Retain the installed line map, component instructions, water analysis, hydraulic plan, flush/isolation access, baseline readings and maintenance responsibilities. A buried system needs a repair plan before those details become inaccessible.
Give every later field operation access to the current line locations and safe working limits.
Locate isolation and flush access before a buried failure requires them.
