五大道历史文化街区, 天津市 / the Wudadao historic district, Tianjin, CN
公共建筑用水器具流量与中水回用可行性调查（五大道历史文化街区） / Fixture flow-rate and greywater-readiness survey of the public building (the Wudadao historic district, Tianjin, CN).
五大道历史文化街区的公共服务用房从没量过龙头与冲厕流量，也没人查过洗手废水能否就近回用于绿地；这两件事都只是没被测过。 / Nobody has ever measured the tap and cistern flow rates at the public service building at the Wudadao historic district Read all of it
Not payable in cash on this rail. Settles as earned credit, $300 proposed.
Proof it takes, the deadline, the level
- Proof逐器具流量数据＋静置计量记录＋排水布置照片＋排序改造清单 / per-fixture flow data + quiet-period meter record + drainage layout photos + ranked retrofit list
- Open until2026-10-18
- Levelintermediate
All of it: the words, the place, the proof
五大道历史文化街区的公共服务用房从没量过龙头与冲厕流量，也没人查过洗手废水能否就近回用于绿地；这两件事都只是没被测过。 / Nobody has ever measured the tap and cistern flow rates at the public service building at the Wudadao historic district, and nobody has checked whether its handwash water could be reused on the adjacent green space. Neither has been measured, that is all.
Fund it for $300. Proof lands onchain when it's done.
How this work is done
How this work is done
A documented method, so this packet comes out the same whoever does it.
Steps
- 逐个器具用量杯与秒表实测流量。 / Measure every fixture's flow with a measuring jug and a stopwatch.
- 静置计量法检查冲厕与管路是否有持续渗漏。 / Use a quiet-period meter read to check for continuous leakage in cisterns and pipework.
- 目视记录排水管路布置，判断能否分流洗手废水。 / Record the drainage layout by eye and judge whether handwash water could be separated.
- 记录就近绿地面积与可承接的回用水量。 / Record the adjacent green area and the reuse volume it could accept.
- 出具按节水量排序的改造清单与中水可行性结论。 / Produce a ranked retrofit list with the greywater-readiness conclusion.
What counts as done
- 逐个器具的实测流量记录 / Measured flow rate recorded for every fixture
- 静置计量前后读数（渗漏判定） / Quiet-period meter readings before and after for the leak finding
- 排水管路布置照片与分流可行性判断 / Drainage layout photos with the separation feasibility finding
- 按年节水量排序的改造清单 / Retrofit list ranked by estimated annual water saved
Proof is measured against these, not judged by taste.
The standard this serves
Water Efficiency. Water efficiency is the quiet discipline of wasting nothing indoors. The EPA's WaterSense program sets the marks: how many gallons a minute a faucet should pass, how to find the leak that runs a toilet all night, how a household's water bill tells a story. Mastery looks like an auditor who can walk a home in an hour and find every hidden gallon. The skill is built one fixture at a time, which is exactly what this packet asks: measure one flow, find one leak, record one truth about where the water goes.
What is promised, and what is not
Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1789693586996_daoxe53","funderWallet":"0xYOU"}.
Open, but not claimable yet. restricted: china-region-gps. This packet requires GPS location proof from a worker in mainland China, and the cross-border data-transfer safeguards that kind of location data needs are not in place on this protocol yet. It stays readable; voting and pledging are free, and funding is separate from claiming.
An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.
Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.
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.
Other acts: vote, pledge, fund
