How to Keep Rainwater Out of an Outdoor Trash Can
A trash can that keeps collecting rainwater usually has a straightforward cause. The lid may be open or blocked by an overfilled bag, the can may sit beneath concentrated roof runoff, or the storage location may leave it exposed to more water than necessary.
Start with those basics before looking for modifications. Keep waste below the rim, clear anything caught along the lid edge, store the can upright, and move it away from downspouts or other concentrated water where possible.
Quick Answer: What to Do When Your Trash Can Fills With Water
Check the lid, fill level, rim, and storage location first. Those four things explain many recurring rainwater problems.
- Close the lid after use.
- Keep bags, boxes, and packaging below the rim.
- Remove bag corners or debris caught along the lid edge.
- Keep the can upright on stable ground.
- Move it away from gutters, roof drip lines, and downspouts.
- Use covered storage where it works for the property.
- If water has already collected, remove it appropriately and clean the can if it has mixed with garbage residue.
An attached lid covers the normal opening, but an ordinary outdoor trash can should not be treated as a watertight container.
Key Facts at a Glance
- Lid position matters: an open or obstructed lid gives rain a direct path into the can.
- Overfilling matters: bags and boxes above the rim can hold the lid open.
- Placement matters: downspouts and roof runoff can expose one container to far more water than normal rainfall.
- Low spots create another problem: the can may sit in pooled water after a storm.
- Standing water makes waste messier: it can soak cardboard, wet bags, and mix with food residue.
- Permanent modifications are not the first fix: for EcoGuard cans, address lid use, fill level, placement, and shelter rather than drilling drainage holes.
Why Is My Trash Can Filling With Water?
Start by figuring out whether the moisture is actually coming from rainfall. A lid left open, garbage above the rim, debris trapped along the edge, wind-driven rain, a damaged lid, or a downspout aimed at the storage area can all let water in.
Internal moisture can have other sources too. Wet organic waste, a leaking garbage bag, high humidity, or condensation may leave the inside damp even when little rain entered through the lid.
The distinction matters. Moving the can will not fix a leaking garbage bag, and replacing a bag will not solve a downspout that pours onto the lid every time it rains.
Does Closing the Lid Keep Rain Out?
A closed lid removes the large opening that an uncovered trash can presents to the rain. That alone can make a substantial difference.
Water can still reach the interior around lid edges, hinge areas, small obstructions, or during wind-driven weather. Keep the lid in its normal closed position whenever the can is not being loaded or emptied.
For more on lid formats, see our guide to attached vs removable trash can lids.
How Does Overfilling Let Water Into a Trash Can?
When bags or boxes rise above the rim, the lid rests on the waste instead of closing normally against the container.
Tied bag tops, bulky cardboard, loose plastic film, and oversized packaging are common offenders. Even a small opening can admit water during a long storm.
If this happens every collection cycle, the issue may be capacity rather than lid use. Compare the household's normal waste volume with the container sizes or additional-cart options permitted by the waste provider.
Why Should I Check the Lid and Rim Before Closing?
A bag corner, drawstring, leaf, piece of cardboard, or loose plastic can keep one section of the lid raised without being obvious from a distance.
Clear anything caught along the rim and let the lid lower normally. There is no need to force it down or try to create an airtight fit.
Does Trash Can Placement Affect How Much Rainwater Gets In?
Yes. Two identical cans can see very different exposure depending on where they are stored.
| Storage Location | Typical Rain Exposure | Main Consideration |
|---|---|---|
| Open driveway | More direct exposure | Keep lid closed and rim clear |
| Beside a house wall | May reduce some direct rain | Watch for roof runoff |
| Under an overhang | Usually less direct rainfall | Make sure runoff is directed elsewhere |
| Covered enclosure | Adds an overhead barrier | Roof openings and drainage still matter |
| Garage or shed | Strong physical shelter where suitable | Consider sanitation, ventilation, and local rules |
A stable surface that does not routinely collect standing water is preferable to a low depression in the driveway or yard.
How Do Roof Runoff and Downspouts Affect a Trash Can?
Concentrated runoff can matter much more than ordinary rainfall. A downspout or roof edge can send a steady stream toward the same part of the lid throughout a storm.
Look at the area during rain if you can do so safely. Is water simply falling around the container, or is a gutter, downspout, roof drip line, drainage channel, or sprinkler directing water at it?
If the can sits in that concentrated flow, changing its position can make a noticeable difference without modifying the container at all.
Do Overhangs, Enclosures, or Covered Storage Help Keep Trash Cans Drier?
An overhead barrier can reduce direct rainfall. A roof overhang, carport, covered side yard, shed, or roofed trash enclosure may all work depending on the property.
Good shelter still needs sensible drainage. Wind-driven rain can reach open sides, and a poorly placed roof edge can concentrate water onto the can instead of protecting it.
If garbage is stored in a garage or shed, also consider sanitation, ventilation, odor, building rules, and the normal collection routine.
What Should I Do if Water Is Already Inside the Trash Can?
Remove the pooled water before adding fresh dry garbage, then deal with whatever the water has been sitting in.
If the water is relatively clean rainwater, remove it in a way appropriate for the property. If it has mixed with food residue, household cleaners, oil, chemicals, or other contaminants, follow applicable local wastewater or disposal guidance.
Inspect the bottom afterward. If it is dirty, wash the can and let it dry before normal reuse. Then correct the lid, fill-level, runoff, or storage issue that allowed the water to collect.
Do not automatically direct dirty trash-can water into a storm drain. Contaminated runoff can carry food residue, chemicals, litter, and other pollutants. Local stormwater and wastewater rules differ.
How Does Standing Water Affect Garbage Bags and Loose Waste?
Water at the bottom of a garbage can quickly turns an ordinary load into a messier one. Cardboard softens, paper packaging gets soaked, damaged bags may sit partly submerged, and leaking food can mix with the pooled water.
Keep household waste securely bagged and avoid leaving loose food at the bottom of the container.
If moisture has already contributed to odor, see how to keep an outdoor trash can from smelling. For washing instructions, see How to Clean an Outdoor Trash Can.
Can Standing Water Attract Pests or Animals?
Clean rainwater is usually less important than what it mixes with. Food residue, leaking bags, exposed garbage, and dirty packaging can make a wet storage area more attractive to insects or animals.
Remove pooled dirty water, clean food residue, and keep waste contained. For more detailed wildlife guidance, see How to Keep Animals Out of Outdoor Trash Cans.
Should I Drill Drainage Holes in My Trash Can?
Do not drill drainage holes in an EcoGuard trash can.
A hole that lets rainwater out can also let garbage liquid, food residue, and contaminated water leak onto the ground. It permanently alters the container as well.
If another trash-can model includes a factory-designed drain or drain plug, follow that manufacturer's instructions. For EcoGuard cans, address the source of the water instead: lid closure, overfilling, placement, concentrated runoff, or shelter.
Should I Add Silicone, Caulk, or Weather Stripping?
Permanent aftermarket seals are not part of the EcoGuard rainwater-management approach described here.
Silicone, caulk, adhesive foam, weather stripping, or drilled hardware can alter lid movement or interfere with normal use. Start by correcting the exposure problem before modifying the container.
Should I Leave the Lid Open to Help the Trash Can Dry?
A drained or freshly washed can can be left open briefly during suitable dry weather so the interior can air out.
Once it is dry enough for normal use, close the lid again. Leaving it open outdoors for long periods invites the next rainstorm, leaves, insects, and debris back inside.
Do Tarps or Temporary Covers Help Keep Water Out?
A temporary cover can reduce direct rain during a particular storm, but it adds another object to manage.
Loose tarps can collect water, blow out of place, create handling problems, or interfere with collection if left on the container. For recurring exposure, a purpose-built overhang or covered storage area is usually easier to live with.
What Should I Do With My Trash Can on Collection Day When It's Raining?
Follow the provider's normal placement instructions and keep the lid closed without bags or boxes protruding above the rim.
Remove tarps, covers, or accessories that would interfere with workers or collection equipment. After pickup, return the can to its usual storage location and check for pooled water before loading new garbage.

EcoGuard Trash Cans and Rain: How the Product Design Fits Into This Guide
EcoGuard offers wheeled outdoor trash cans in 32-, 45-, 48-, and 64-gallon capacities. The 32/45 family uses polypropylene, while the 48/64 family uses polyethylene. Both families have attached hinged lids and rear wheels.
The 48/64 family also includes a documented steel stop bar intended for applicable automated and semi-automated collection lifters. That is a collection-interface feature unrelated to rain protection.
EcoGuard's attached lids cover the normal trash opening, but they are not documented as watertight seals. Wind-driven rain or water reaching gaps around the lid can still enter.
If rainwater is collecting repeatedly, troubleshoot the source: lid position, overfilling, rim obstruction, storage placement, or concentrated runoff.

Troubleshooting Table: Why Water Gets In and What to Do
| What You Notice | Likely Cause | First Thing to Try |
|---|---|---|
| Water after lid was left open | Direct rainfall through opening | Keep lid closed after use |
| Lid sits on top of bags | Can is overfilled | Keep waste below the rim |
| One side of lid stays raised | Bag or debris caught at rim | Clear the lid edge |
| Water appears after every storm in one location | Roof or downspout runoff | Move can away from concentrated flow |
| Can sits in water after rain | Low storage spot | Move to better-drained stable ground |
| Water still appears despite normal lid closure | Wind-driven rain, damage, or lid gaps | Inspect the can and consider better shelter |
The pattern usually points to the cause. A can that gets wet only beneath a downspout needs a different fix from one whose lid is held open by an overflowing bag.
FAQs About Rainwater in Outdoor Trash Cans
How Do I Keep Rain Out of My Trash Can?
Keep the lid closed, waste below the rim, and the lid edge clear. If possible, move the can away from concentrated roof runoff and use sheltered storage.
Why Does Water Still Get in When the Lid Is Closed?
Wind-driven rain can reach gaps around the lid or hinge, and a small piece of debris may prevent full closure. Concentrated roof runoff can also overwhelm an otherwise reasonable storage position.
Should Outdoor Trash Cans Be Stored Under Cover?
Covered storage can reduce direct rain exposure where it fits the property. Make sure the shelter itself does not direct runoff onto the container.
What Should I Do if Rainwater Pools Inside My Garbage Can?
Remove the water appropriately, clean the container if it has mixed with garbage residue, let it dry, and correct the source of the water before loading fresh waste.
Should I Drill Holes in the Bottom of My Trash Can?
Not in an EcoGuard trash can. The holes would also allow dirty garbage liquid to escape and would permanently modify the container.
Does an Attached Lid Make a Trash Can Waterproof?
No. An attached lid stays connected to the container and covers the normal opening, but that does not establish watertight performance.
Can a Downspout Cause a Trash Can to Fill With Water?
Yes. A downspout can direct far more water toward one part of the can than ordinary rainfall. Moving the container away from the discharge can reduce that exposure.
Final Takeaway: A Simple Routine to Keep Your Trash Can Drier
Most recurring rainwater problems come down to lid closure, overfilling, or storage location. Keep waste below the rim, clear anything caught along the lid edge, and move the container away from concentrated roof runoff or low spots where water pools.
If water is already inside, remove it appropriately, clean the can if it has mixed with food or garbage residue, and let the container dry before loading it again. Covered storage can help when the property allows it.
EcoGuard's attached lids cover the normal opening, but they are not documented as watertight seals. Fix the source of the water rather than drilling or permanently modifying the can.
