Irrigation 8 — Installing, commissioning and auditing the system
Trenching depths, laying and joining pipe, flushing before you fit heads, setting arcs, and the audit that tells you whether the system you just built does what you designed. Then how to re-audit it every year.
Not planted yet — but the plan for it is final
The practical task and the checklist below are exactly what this lesson will teach. What is missing is the written explanation and the curated links, each one fetched and verified before it ships.
In the meantime the checklist is genuinely usable on its own. Take it outside.
Do this on your own block
Field journal entry
Irrigation as-built and audit
Record the as-built layout — mainline route, valve positions, station numbers and what each covers — and the results of your commissioning audit: pressure at the furthest head on each station, catch-cup uniformity, and final run times.

- Run times set from the audit, not from a guess
