Record Orangi Town lane drain condition from the dry lane surface (2026-07-18)

Orangi's self-built sanitary lane drains, developed through the community-financed Orangi Pilot Project starting in the 1980s, remain one of the world's most studied low-cost sanitation models — but their day-to-day condition is rarely documented block by block. A photo record from the dry lane surface, without touching or entering any drain, tracks where maintenance is most needed. Standard: UN-Habitat urban drainage guidance + SDG 11.5 / SDG 6.6. Proof: Photo + GPS + written condition log from the dry lane surface Method (UN-Habitat urban drainage guidance + SDG 11.5 / SDG 6.6.): 1. Walk only the dry lane surface — never enter, open, or touch any drain. 2. Photograph the drain cover and surrounding lane condition from a safe standing position. 3. Record GPS coordinates, date, and a plain-language description of visible condition. 4. Note any overflow or blockage without approaching or touching it. 5. Submit the photos and notes as your proof — a trained crew handles any drain work. Done when: Photo + GPS + written condition log from the dry lane surface

$80 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.

Proof

Photo + GPS + written condition log from the dry lane surface

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 30–75 minutes. Method of record: EPA green-infrastructure inspection (bioretention / bioswale / permeable pavement function + maintenance)

Bring

• measuring tape
• GPS phone
• camera
• trowel / probe
• data sheet
• gloves

Steps

1. 1. Locate the GI asset; record GPS; identify the type (rain garden / bioswale / permeable pavement / tree filter).
2. 2. Photograph the asset, its inlet, and its outlet/overflow.
3. 3. Check the inlet and outlet for blockage (sediment, trash, mulch) and note whether flow can enter/leave freely.
4. 4. Check for standing water and estimate whether it drains within the design window (typically <24-48h after rain); probe media if dry.
5. 5. Assess vegetation/media condition and estimate sediment/trash accumulation depth.
6. 6. Note erosion, bypass, or structural damage and list the maintenance needed.
7. 7. Enter asset type, condition, inlet/outlet status, drainage observation, sediment level, maintenance needs, GPS, photos; sign.

If it does not match the plan

• Standing water persists > 48h after rain -> flag failed infiltration (clogged media) for rehab.
• Inlet or outlet blocked -> flag for cleaning; the asset isn't capturing runoff.
• Erosion, undercutting, or flow bypassing the asset -> flag for repair.
• Documentation only — no digging out media or altering structures.

What counts as done

• Asset type + overall condition recorded
• Inlet + outlet clear/blocked status recorded
• Standing-water / infiltration observation recorded
• Sediment/trash level + maintenance recommendations + GPS + photos

Proof is measured against these, not judged by taste.
