These are the supplies that matter most after a flood, whether you are stocking them at home or donating them to people who were hit.
Water Filters/Purification
After a flood, access to clean drinking water becomes the most critical need. Floodwaters are often contaminated with harmful bacteria, sewage, chemicals, and debris, which can lead to serious health problems like cholera, dysentery, and gastrointestinal diseases. Water filters and purification tablets handle germs, but neither removes chemicals, so leave floodwater itself alone, start from the cleanest source you can find, and pair a filter with boiling or disinfection. Bottled water comes first. Filters and tablets handle germs in clear water, but nothing you carry makes floodwater fouled with fuel, sewage, or chemicals safe to drink.

For long-term (storage) and effective water purification after a flood, calcium hypochlorite is an effective alternative to liquid bleach. Unlike bleach, which loses potency over time, calcium hypochlorite (commonly used in pool treatments) can be stored as a solid powder and mixed with water when needed to create a potent disinfectant solution. This solution can be used to purify large quantities of water for drinking over an extended period.

Non-Perishable Food Items
Food is essential for survival, especially during emergencies when access to cooking facilities or fresh groceries is limited. Non-perishable food items, such as canned goods, protein bars, and ready-to-eat meals, provide a reliable source of nutrition for those displaced by flooding. These items can be stored for long periods and require minimal preparation, ensuring that people have access to sustenance while recovering from the disaster.

Prescription Medications and Antibiotics
In flood-affected areas, medical conditions can quickly worsen if prescription medications are unavailable. It's important to ensure that people have access to their regular medications, including antibiotics for infection prevention and treatment. Floodwaters expose individuals to bacteria and other pathogens, increasing the risk of infections. Having antibiotics on hand can help prevent minor injuries from becoming life-threatening.

Generators
Generators provide essential backup power during outages, enabling people to run critical appliances such as refrigerators, medical devices, and lights. Generators also power cleanup tools. Run them outdoors only, at least 20 feet from any home or shelter with the exhaust pointed away, and keep a battery CO alarm inside. Having access to power allows people to charge devices, maintain some comfort, and keep their food and medicine properly stored.

Warm Clothing, Socks, and Underwear
Flooding often leads to prolonged exposure to cold and wet environments, which can cause hypothermia or other cold-related illnesses. Providing dry, warm clothing, including socks and underwear, is essential for protecting against the elements and maintaining hygiene. These items are also necessary for people staying in shelters where access to laundry facilities may be limited.
Blankets and Sleeping Bags
Warm blankets and sleeping bags are crucial for those displaced from their homes or living without heat. These items provide warmth and comfort, especially in shelters or temporary housing situations where heating may be inadequate. Offering quality sleep protection also helps reduce the risk of cold-related health issues.
First-Aid Kits
Flooding increases the risk of injuries, from minor cuts and scrapes to more serious wounds caused by debris. A well-stocked first-aid kit with bandages, antiseptics, and basic medical supplies allows people to treat minor injuries, reducing the chances of infection. Quick access to first-aid materials can be lifesaving in situations where medical care is delayed.

Flashlights and Batteries
In the aftermath of a flood, power outages can last for days or even weeks. Flashlights and extra batteries provide critical lighting in darkened homes, shelters, and streets, ensuring safety and visibility. Reliable lighting is essential for navigating through damaged areas and for night-time recovery work.

Camp Stove and Propane
With the potential for extended power outages, a camp stove allows people to prepare meals and boil water for sanitation. Propane-powered stoves offer a portable, reliable cooking solution, especially when traditional gas or electric appliances are unusable. These stoves are easy to transport, which suits them to camps and cooking outside a temporary shelter. Never run one inside a home, shelter, or tent.

Fuel Cans
Fuel is essential for running generators and other equipment during recovery efforts. Gasoline or diesel fuel can power everything from vehicles to tools needed for cleanup. Providing fuel cans ensures that those with generators can maintain their power supply or access transportation when roadways are cleared.

Space Heaters
Space heaters provide critical warmth in homes, shelters, or temporary housing when central heating systems are unavailable due to flooding. These heaters hold off hypothermia on cold nights. A propane heater must be rated for indoor use, with a window cracked and a CO alarm running, and it goes off before you sleep.

Shovels, Saws, Tools
After the floodwaters recede, many areas will require significant cleanup. Shovels and other basic tools, such as hammers, saws, and chainsaws, allow people to begin clearing debris, repairing minor damage, and restoring their homes. Chainsaws are particularly useful for cutting through fallen trees, large branches, and other heavy debris that may block roads or damage property. Saws, both hand and power varieties, help with cutting materials for repairs. Having access to these essential tools speeds up the recovery process and empowers individuals to take action in restoring their property and clearing pathways quickly.
GMRS Radios
In the aftermath of a flood, communication can become a critical challenge due to power outages, damaged infrastructure, or overloaded cellular networks. General Mobile Radio Service (GMRS) radios provide an effective solution for staying connected with family, neighbors, or emergency personnel in these situations. GMRS radios have a longer range than traditional walkie-talkies, with some capable of reaching up to several miles, depending on terrain and conditions. They can be especially useful for coordinating rescue efforts, reporting hazards, or maintaining communication with isolated communities.
GMRS radios are easy to use, but they need an FCC license. One license covers the whole family for ten years, and there is no exam. Equipped with multiple channels, these radios allow for clear and uninterrupted communication, even in busy emergency zones. Having GMRS radios on hand ensures a reliable form of communication when conventional systems fail, making them an essential tool for disaster recovery and survival.

Extension Cords
Extension cords become important when using generators or powering multiple devices from limited outlets. They allow for greater flexibility in distributing electricity to essential appliances, tools, or heaters during recovery efforts. Heavy-duty, weather-resistant extension cords are especially useful for outdoor work in disaster zones.
Towels
Towels are essential for staying dry and maintaining hygiene, especially after wading through floodwaters. Quick-drying microfiber towels are particularly useful, as they dry fast and resist mildew, providing warmth and comfort in challenging environments.
Waterproof Boots
Floodwaters carry contaminants, debris, and sharp objects that can cause injury or infection. Waterproof boots protect people as they move through flooded areas, keeping their feet dry and preventing exposure to hazardous materials. High-quality boots are essential for rescue and recovery efforts in wet conditions.
Tarps and Plastic Sheeting
Tarps and plastic sheeting provide temporary shelter and protection from the elements. They can cover damaged roofs, windows, or belongings that need to be shielded from rain or wind. These materials are also useful for creating makeshift shelters for displaced people or protecting critical supplies from further damage.
Disposable Gloves and Masks
During cleanup efforts, people can be exposed to hazardous materials such as mold, chemicals, and sewage. For mold and sewage cleanup the minimum is an N95 respirator, goggles, and protective gloves. A loose dust mask does not stop mold spores. These protective items are also important for preventing respiratory illnesses caused by mold exposure.

Bug Spray
Flooding often leads to stagnant water, which becomes a breeding ground for mosquitoes and other insects. This can increase the risk of insect-borne diseases such as West Nile Virus or Zika. Having bug spray on hand is essential for personal protection during recovery efforts. Repellents containing DEET, Picaridin, or oil of lemon eucalyptus are effective at keeping insects away and reducing the chances of bites and disease transmission.
Bug spray can be particularly useful for those working outside in areas affected by floodwaters, as well as for people staying in shelters or areas with minimal infrastructure. Ensuring that bug spray is part of your emergency kit helps protect against the discomfort and potential health risks associated with increased insect activity post-flood.
Body Wipes and Hand Sanitizer
In post-flood conditions, maintaining personal hygiene can become a challenge, especially if access to clean water is limited. Body wipes offer a practical solution for cleaning yourself when showers or running water are unavailable. These wipes help remove dirt, sweat, and bacteria from the skin, preventing infections and keeping you comfortable during prolonged periods without proper sanitation facilities. Body wipes are portable and easy to store, making them a must-have in any survival kit.
is equally important, especially after handling debris, contaminated water, or interacting with shared surfaces in shelters. With the risk of spreading germs and disease, particularly in close quarters, having hand sanitizer on hand helps reduce the risk of illness when soap and water aren't available. Look for alcohol-based sanitizers with at least 60% alcohol to ensure effectiveness in killing bacteria and viruses. These items are small but essential for preventing the spread of infection in disaster-stricken areas.
Questions this answers
Tap a question for the short answer.
What supplies do flood victims need most?
Clean drinking water is the most critical need, so bottled water comes first, backed by water filters or purification tablets. After that come non-perishable food, prescription medications and antibiotics, phone chargers and generators, dry warm clothing, blankets and sleeping bags, first-aid kits, and flashlights with extra batteries.
What should I donate after a flood?
Useful donations include water filters or purification tablets, non-perishable food, portable phone chargers, generators with fuel cans and extension cords, warm clothing, socks and underwear, blankets and sleeping bags, first-aid kits, flashlights and batteries, towels, waterproof boots, cleanup tools, and tarps or plastic sheeting.
How do I get clean drinking water after a flood?
Leave floodwater itself alone. It carries bacteria, sewage, chemicals, and debris, and filters and purification tablets handle germs but not chemicals. Start from the cleanest source you can find and pair a filter with boiling or disinfection. For long-term treatment, calcium hypochlorite stores as a solid powder and mixes with water into a disinfectant solution.
What gear do I need for flood cleanup?
Plan on shovels, hammers, hand and power saws, and a chainsaw for fallen trees and heavy debris. Add waterproof boots to protect your feet from contaminants and sharp objects, a generator with fuel cans and heavy-duty weather-resistant extension cords, and tarps or plastic sheeting for damaged roofs and windows.
How do I communicate after a flood when cell service is down?
GMRS radios are my answer. They have a longer range than traditional walkie-talkies, with some reaching up to several miles depending on terrain, are easy to use, and offer multiple channels. They need an FCC license, with no exam. Solar or high-capacity power banks keep phones charged for when networks come back.
Can I use pool shock to purify water after a flood?
Yes. Calcium hypochlorite, the compound commonly used in pool treatments, is an effective alternative to liquid bleach. It stores as a solid powder without losing potency the way bleach does, and you mix it with water as needed to make a disinfectant solution for purifying large amounts of drinking water.
