Audit the irrigation distribution uniformity on a farm served by the Enterprise Canal, Clovis

Canal-delivered water on this farm has never had a distribution-uniformity check — an uneven system wastes exactly the water the canal worked to deliver. Standard: undefined Proof: catch-can readings + photo set + compiled findings + GPS Method (undefined): 1. Walk the irrigation system with the grower and photograph the delivery method (drip, micro-spray, flood) as found. 2. Run a catch-can distribution-uniformity test across 2+ representative zones. 3. Check for leaks, clogged emitters or pressure imbalance along the mainline. 4. Compile the findings naming the priority efficiency fixes. Done when: catch-can readings + photo set + compiled findings + GPS

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–120 minutes. Method of record: Mobile Irrigation Lab catch-can distribution-uniformity audit

Bring

• matched catch cans (or cups)
• measuring cylinder / ruler
• pressure gauge
• stopwatch
• GPS phone
• camera
• data sheet

Steps

1. 1. Confirm the site/zone; record GPS; identify the system type (sprinkler / drip / micro).
2. 2. Sprinkler zones: lay catch cans on a grid across the zone, run the zone a fixed time, and measure the water depth in each can.
3. 3. Compute distribution uniformity (low-quarter DU) from the catch-can depths.
4. 4. Drip/micro zones: measure emitter flow at several points (fill a container over a fixed time) and inspect for clogs and leaks.
5. 5. Read operating pressure at the zone; note leaks, broken/misaligned heads, and overspray onto pavement.
6. 6. Review the run schedule against plant/soil need (over/under-watering, runoff).
7. 7. Rank fixes (head repair, pressure regulation, schedule change) by water savings; record DU/emitter flow, pressure, leaks, schedule note, photos; sign.

If it does not match the plan

• Low-quarter DU < 0.65 (sprinkler) -> flag poor uniformity for repair/redesign.
• Visible runoff or overspray onto pavement -> flag schedule/head correction.
• Emitter clogging or line leaks (drip) -> flag maintenance.
• Broken/misaligned head -> flag for repair. Documentation only; no repairs by surveyor.

What counts as done

• Distribution uniformity (or drip emitter-flow) recorded
• Operating pressure recorded
• Broken/leaking components + overspray noted
• Schedule-vs-need note + ranked fixes + GPS + photos

Proof is measured against these, not judged by taste.
