Flood-irrigation basin distribution-uniformity audit -- an ornamental date-palm grove at the edge of town, Desert Hot Springs, CA 92240

This grove's individual date palms are watered by flood-irrigation basins that have never had a distribution-uniformity check; eroded or breached basin walls waste real water in a valley drawing on a shared groundwater basin. Standard: Mobile Irrigation Lab catch-can distribution-uniformity audit (agricultural/landscape irrigation); SDG 6.4/2.4 water-use efficiency Proof: catch-can/basin-fill photos + GPS + per-basin condition log + ranked repair list Method (Mobile Irrigation Lab catch-can distribution-uniformity audit, ~60-120 min): 1. Confirm the site/zone; record GPS; identify the system type (sprinkler / drip / micro). 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. Compute distribution uniformity (low-quarter DU) from the catch-can depths. 4. Drip/micro zones: measure emitter flow at several points (fill a container over a fixed time) and inspect for clogs and leaks. 5. Read operating pressure at the zone; note leaks, broken/misaligned heads, and overspray onto pavement. 6. Review the run schedule against plant/soil need (over/under-watering, runoff). 7. Rank fixes (head repair, pressure regulation, schedule change) by water savings; record DU/emitter flow, pressure, leaks, schedule note, photos; sign. Equipment: matched catch cans (or cups), measuring cylinder / ruler, pressure gauge, stopwatch, GPS phone, camera, data sheet Done when: Distribution uniformity (or drip emitter-flow) recorded; Operating pressure recorded; Broken/leaking components + overspray noted; Schedule-vs-need note + ranked fixes + GPS + photos

Pay
$85 proposed

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
catch-can/basin-fill photos + GPS + per-basin condition log + ranked repair list

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

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.

What counts as done

Proof is measured against these, not judged by taste.

Claim it on the board

Claiming is free. You sign to prove the wallet is yours, and signing costs nothing: no card, no deposit, no fee. An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.

Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
