Build a household cistern so captured rain covers more of the dry weeks.

Once a household already runs a rain barrel, the real fix for Iztapalapa's weekly water-truck cycle is more storage, a larger sealed cistern that banks rainy-season capture for the weeks between deliveries. Many families currently store water in uncovered tanks that lose volume and collect debris. A proper cistern with a tap and overflow line multiplies how long stored water lasts and keeps it cleaner.

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 — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Steps

1. Confirm the host invites the work and walk the roof runoff and existing storage setup together.
2. Set the cistern tank on a stable, leveled base at ground level, never elevated on unsupported blocks.
3. Connect the roof runoff line and any existing rain barrel as a first-flush feed into the cistern inlet.
4. Install a tap near the base and a screened overflow so excess water drains away from the foundation.
5. Photograph the completed cistern, tap, and overflow with the host present and record the capture-ready date.

What counts as done

• Photo of the cistern set on its stable base
• Photo of the connected roof-runoff inlet and screened overflow
• Photo of the host confirming the finished install

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.
