Fit a trash-catching filter insert into a storm drain before the rains hit

Ecatepec's lower colonias flood repeatedly in the rainy season, and a fast, cheap way to cut how much street trash reaches the drain system is a simple filter insert that catches debris at the inlet. A fitted insert is far easier to clean than an unfiltered drain that backs up. This is public-space work ahead of the rainy season. Standard: UN-Habitat urban drainage guidance; SDG 11 (Sustainable Cities and Communities) Proof: Photo of the installed filter insert seated under the grate Method (UN-Habitat urban drainage guidance; SDG 11 (Sustainable Cities and Communities)): 1. Locate the storm drain inlet and confirm it is a public, accessible grate. 2. Measure the inlet opening for the filter insert. 3. Fit the mesh filter insert under the grate, seated securely. 4. Test that water still drains freely through the filtered opening. 5. Photograph the installed filter insert and record the date, ahead of the rainy season. Done when: Photo of the installed filter insert seated under the grate

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 30–75 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.
