Install a certified water filter for a Makoko stilt household

Makoko's stilt homes sit over the Lagos Lagoon, and most households rely on sachet water or untreated lagoon water for cooking and washing because no piped mains reach the stilt sections. Contaminated water drives diarrheal illness in children here every rainy season. A host-invited household filter turns unsafe water into a daily safety habit without any contact with the lagoon itself. Standard: WHO Guidelines for Drinking-water Quality; SDG 6.1 Proof: photo of installed filter + host sign-off Method (WHO Guidelines for Drinking-water Quality; SDG 6.1): 1. Meet the host family and confirm they invited the filter install. 2. Inspect the household's current water storage container for cracks or an open top. 3. Mount the certified point-of-use filter unit at the household's water station. 4. Flush the new filter per the manufacturer's start-up instructions using clean supplied water. 5. Walk the household through daily cleaning and cartridge-check steps. 6. Photograph the installed filter and record the household's confirmation. Done when: photo of installed filter + host sign-off

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 30–60 minutes. Method of record: EPA drinking-water sampling (3Ts / LCR first-draw where lead is in scope)

Bring

• GPS-capable phone
• test kit for each named analyte (nitrate/coliform/arsenic/lead as specified)
• clean sample bottle + label
• nitrile gloves
• camera

Steps

1. 1. Navigate to the sampling point; confirm GPS is inside the posting radius; record the waypoint.
2. 2. Photograph the tap or wellhead with a legible timestamp.
3. 3. If first-draw is required, sample after >=6h stagnation; if flushed, run the tap 2-3 minutes first, then sample.
4. 4. Fill the bottle without touching the inside; cap immediately.
5. 5. Run each test per kit instructions; wait the exact develop/incubation time; read and record every value with units.
6. 6. Record coliform as present/absent after the stated incubation window.
7. 7. Enter all readings, units, GPS, time, and photos into the proof record; sign it.

If it does not match the plan

• Nitrate > 10 mg/L -> tag 'exceeds EPA MCL'; advise no infant consumption pending certified-lab confirmation.
• Total coliform present -> advise disinfection + retest; recommend lab confirmation.
• Arsenic > 10 ppb or Lead > 15 ppb -> tag exceedance; recommend certified-lab confirmation before any consumption guidance.

What counts as done

• GPS waypoint recorded inside the posting radius
• Timestamped photo of the exact sampling point
• Each required analyte recorded with a numeric value + units (or present/absent)
• Sampling type (first-draw vs flushed) explicitly noted

Proof is measured against these, not judged by taste.
