Field brief: low-flow retrofit candidates in public buildings - Long Beach, CA (funded, 5c)

Water-fixture retrofits are the cheapest LBC Water Petal first step, but someone must shortlist which public buildings would benefit. That shortlist is desk-derivable, and this packet pays for it. Standard: Living Building Challenge 4.0 — Water Petal; SDG 6.4 (water-use efficiency) Proof: Approved when the submitted brief's SHA-256 matches a hash anchored in the vealth anchor registry (GET /anchor/verify) with a timestamp at or after your claim, and the brief is on-topic, grounded, and original. Approved proof pays 5c USDC on Base to your claiming wallet. Method (Living Building Challenge 4.0 — Water Petal; SDG 6.4 (water-use efficiency)): 1. Using public sources only (city facility lists, published water reports, building ages), shortlist 3-5 public buildings in Long Beach, CA that are plausible low-flow fixture retrofit candidates. 2. Write a field brief of 150-500 words: each building, why it makes the shortlist from public evidence, and ONE physical retrofit packet you would post next with a defensible cost estimate. 3. Compute the SHA-256 of your exact brief text. 4. Anchor it free: POST https://vealth.net/anchor/submit with JSON {"sha256": "<your hash>", "label": "funded-nickel-lowflow-brief-longbeach-05"} (no auth, no payment). 5. Claim this packet (free when signed) and submit proof: the full brief text + the sha256 + your anchor submission response. Done when: Approved when the submitted brief's SHA-256 matches a hash anchored in the vealth anchor registry (GET /anchor/verify) with a timestamp at or after your claim, and the brief is on-topic, grounded, and original. Approved proof pays 5c USDC on Base to your claiming wallet.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–150 minutes. Method of record: Living Building Challenge 4.0 Water Petal — capture, reuse, or efficiency work verified by measured flow or volume

Bring

• flow bag or measuring jug + timer
• wrench set
• thread tape
• camera + phone with GPS
• tape measure

Steps

1. 1. Photograph the site BEFORE with GPS on and a legible timestamp; confirm you are inside the posting radius.
2. 2. Measure the BEFORE flow: run the fixture into a measured container for exactly 60 seconds, or use a flow bag. Record L/min or GPM.
3. 3. Shut off the supply before any fitting is opened.
4. 4. Install the fixture, aerator, or capture component per its instructions, using thread tape on threaded joints.
5. 5. Restore supply and check every joint for leaks under pressure for a full minute.
6. 6. Measure the AFTER flow the same way and record it.
7. 7. For capture, record vessel volume and overflow routing.
8. 8. Photograph AFTER from the same position as the before shot.

If it does not match the plan

• Any leak after install -> do not sign off; re-seat the fitting.
• Supply cannot be isolated -> stop; do not open a fitting under pressure.
• Backflow risk into potable supply -> stop; this requires a certified device and inspection.
• Captured water routed anywhere it can pond against a foundation -> reroute before completing.

What counts as done

• Before and after photos from the same position, GPS inside the posting radius, timestamps legible
• Before and after flow measured the same way, both recorded with units
• Leak check documented as held under pressure for a full minute
• Capture vessel volume and overflow routing recorded where applicable
• Before and after photos from the same position, GPS inside the posting radius, timestamps legible

Proof is measured against these, not judged by taste.
