Set up a rooftop rain barrel for a water-scarce Iztapalapa home

Iztapalapa's hillside colonias like San Miguel Teotongo often receive piped water only once a week, so families rely on trucked water stored in open drums that lose volume to evaporation and breed mosquitoes. A sealed, screened rooftop rain barrel catches roof runoff during Mexico City's rainy season and stretches the days a household can go between water-truck deliveries. This is simple, ground-level work at a home that has invited the install. Standard: UN-Habitat urban water resilience guidance; SDG 6 (Clean Water and Sanitation) Proof: Photo of the sealed barrel connected to roof runoff plus host confirmation Method (UN-Habitat urban water resilience guidance; SDG 6 (Clean Water and Sanitation)): 1. Confirm with the host that the install is invited and find a roof edge or downspout with clear runoff. 2. Mount a food-grade barrel with a tight, screened lid on a stable, leveled stand at ground level. 3. Run a simple gutter or funnel from the roof edge into the barrel inlet. 4. Fit a mosquito screen over the inlet and the overflow outlet. 5. Photograph the finished barrel with the host present and record the install date.

$160 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.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: EPA WaterSense fixture flow-rate + leak audit

Bring

• flow-rate measurement bag + timer
• toilet dye tablets
• moisture meter
• GPS / address
• camera
• tablet / data sheet

Steps

1. 1. Confirm the address; get a staff escort; photograph each fixture group.
2. 2. Measure flow rate at each faucet/shower with the bag-and-timer method; record gallons per minute (gpm).
3. 3. Test each toilet for leaks with a dye tablet (wait 10 min, check for color in the bowl); record flush volume.
4. 4. Inspect fixtures, meters, and irrigation for visible leaks/drips; note each.
5. 5. Read the water meter with all fixtures off; note any movement (indicates a hidden leak).
6. 6. Rank WaterSense fixture upgrades + leak repairs by estimated water/cost savings.
7. 7. Record flow rates, leak results, meter check, ranked measures, and photos into the proof record; sign.

If it does not match the plan

• Meter moving with all fixtures off AND active water damage (wet drywall, ceiling stain, pooling near electrical) -> STOP: possible electrical exposure; keep clear, route to a licensed plumber (and electrician if water contacts wiring). The agent documents, never opens walls.
• Suspected cross-connection / backflow risk (hose-bib, irrigation, boiler makeup) -> flag for a licensed plumber backflow test; potable-water contamination is a health hazard — do not test-operate the connection.
• Toilet dye migrates into the bowl -> flag a leaking flapper/valve for repair.
• Meter moves with all fixtures off -> flag a hidden leak for investigation.
• Faucet > 2.2 gpm or showerhead > 2.0 gpm -> recommend a WaterSense upgrade.
• No electrical/gas work; documentation only — flag suspected pipe damage, do not disassemble.

What counts as done

• Flow rate (gpm) recorded per fixture
• Toilet leak result + flush volume recorded per toilet
• Meter-with-all-off check recorded
• Ranked upgrade/repair measures + photos + address confirm

Proof is measured against these, not judged by taste.
