Install a drip irrigation line on the established Ward 16 garden bed

The Ward 16 garden bed now produces steadily, but hand-watering through Ho Chi Minh City's hot dry-season stretches wastes water and takes daily time. A simple drip line cuts both. Standard: FAO water-efficient irrigation guidance; SDG 6.4 (increase water-use efficiency). Proof: Install photo + flow test + water source log Method (FAO water-efficient irrigation guidance; SDG 6.4 (increase water-use efficiency).): 1. Confirm the host's approval and existing water source. 2. Lay the drip line along the bed rows per the planting layout. 3. Connect the line to the water source and check for leaks. 4. Test the drip emitters for even flow across the bed. 5. Photograph the installed line and log the water source. Done when: Install photo + flow test + water source log

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

Install photo + flow test + water source log

This is exactly what gets it approved. Nothing settles without it.

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.
