A typical scenario (an illustrative story, not a review from any specific customer)

The morning the water left the space under a stilt house in Khlong Khlung

Uncle Sompong is a rice farmer in his sixties in Khlong Khlung district, Kamphaeng Phet. He lives with his wife and seven-year-old granddaughter in a traditional wooden house raised on stilts, not far from the Ping River. This year the rain fell hard for days on end. Water from the surrounding fields and side channels spread beneath the house until it lapped at the bottom step. Part of the paddy stored in the granary got wet, the walking tractor sat half submerged, and the concrete kitchen extension built on the ground floor stood in water for several days.

On the morning the water began to fall, Uncle Sompong was the first one down the stairs. He found brown mud lines painted around every wooden post, bags of fertiliser giving off a sour stench, and an old mattress stored under the house so soaked he could not lift it. In the kitchen, a smell like a drain hung in the air all day. His wife, Aunt Boonruean, poured bleach across the floor, scrubbed it until it looked clean, and kept an electric fan running day and night.

Three days later the floor looked dry, yet a musty odour still drifted up from beneath the house whenever the breeze died down. White specks appeared in the corners of the wooden food cabinet. Tiny black dots spread across the kitchen's plastered wall. Their granddaughter began sneezing and rubbing her nose every morning, and Uncle Sompong had a scrape on his shin from wading out to help a neighbour carry belongings. When their son came home from his job in Kamphaeng Phet town, he took his father to the hospital first and then started looking for a proper way to recover a flooded house: a way that made it actually safe, not just clean-looking.

Stories like this one are playing out across Khanu Woralaksaburi and Khlong Khlung this year, because a flood brings far more than water. It carries invisible passengers that settle into wood, plaster and furniture.

The 2026 Kamphaeng Phet Flood Situation and the National Picture

According to the DDPM report dated 2 October 2026, Kamphaeng Phet had flood-affected areas in two districts, Khanu Woralaksaburi and Khlong Khlung, covering 3,128 households, with water levels reported as falling. Nationally, the DDPM reported on the same day that flooding was affecting 31 provinces plus Bangkok, a total of 1,245,581 households and about 3,535,206 people. The main causes were heavy to very heavy rain combined with runoff flowing down from the north. All of these numbers are updated daily, so always check the latest announcements from local authorities as well.

The Ping River runs through the heart of Kamphaeng Phet. Many homes in Khanu Woralaksaburi and Khlong Khlung sit among farmland: rice paddies, sugarcane, cassava fields and orchards. Older homes are often wooden houses on stilts, while newer ones tend to be single-storey concrete homes or half-wood, half-concrete houses with a kitchen and bathroom added on the ground floor. Each type suffers differently when water stands for days. Stilt houses deal with water-logged timber and musty air rising from below. Concrete homes deal with moisture wicking into walls and mold growing behind wallpaper or under floor tiles.

The good news is that falling water means families can start going home. But this is also the moment that calls for the most care, because people often move straight back in while the house is still damp, with mud still in corners and plenty of invisible germs still around. Planning a step-by-step recovery from the very first day the water drops matters a great deal for everyone's health.

Every Kind of Contamination a Kamphaeng Phet Flood Brings: Bacteria, Viruses, Mold and Odour

Floodwater that has crossed rice fields, animal pens, toilets, septic tanks and drains is not clean water. It carries contamination from many sources at once. Both the World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC) advise treating all floodwater as contaminated and cleaning anything it touched properly. Here is what to watch for, group by group.

1. Faecal bacteria and sewage

The most common group is bacteria from human and animal faeces, such as E. coli, Salmonella and Shigella. When septic tanks and latrines in a village flood, their contents spread with the water and settle on floors, walls, furniture and kitchenware. Someone who touches a contaminated surface and then their mouth, or who eats food placed on it, can develop diarrhoea, stomach cramps, nausea, vomiting and fever.

2. Leptospirosis

Farming areas like Khanu Woralaksaburi and Khlong Khlung have large populations of field rats. When fields flood, Leptospira bacteria shed in rat urine mix into the water and mud. The bacteria enter the body through cuts, scrapes or skin that has softened after long soaking. Warning signs include a sudden high fever, headache, severe muscle pain especially in the calves, and red eyes. Anyone who has waded through water or mud and develops these symptoms should see a doctor immediately and mention the wading. Do not wait to see if it passes. Thailand's Department of Disease Control repeats this warning every flood season.

3. Viruses carried by contaminated water

Norovirus and rotavirus are major causes of acute diarrhoea. They spread very easily via contaminated surfaces and unwashed hands, especially in homes with small children who put things in their mouths. In the weeks after a flood, people are often exhausted and short on sleep, which also makes respiratory infections more likely.

4. Mold, the problem that grows after the water goes

Mold does not always arrive with the water. Its spores are everywhere in the air already. But when they land on wood, fabric, mattresses, paper or walls that stay wet for more than 24 to 48 hours, they germinate into threads and spread quickly. The late rainy season in lower northern Thailand is still humid, so water-logged wooden houses dry slowly and become ideal mold habitat. Airborne spores trigger allergies, coughing, sneezing, a blocked nose and itchy eyes, and can set off asthma attacks.

5. Musty and sewage odours

The musty smell rising from under a house or from the corner of a room is more than a nuisance. It comes from volatile compounds released by mold and bacteria as they break down organic matter such as mud, leaves, wet paddy and food scraps. The smell is a signal that microbes are still active inside the home, even when the surfaces look clean.

Who is most at risk

The people who need extra protection are older adults, young children, pregnant women, people with chronic conditions such as diabetes, kidney disease, lung disease, asthma or allergies, and anyone with weakened immunity. In rural Kamphaeng Phet households, grandparents often look after grandchildren at home, so the most vulnerable people frequently live under the same roof. Making the house genuinely clean is therefore a health decision for the whole family, not a cosmetic one.

What Kamphaeng Phet Families Carry After the Water Recedes

Health. When someone in the house gets diarrhoea, has an allergy flare-up or runs a fever after wading, the burden falls on whoever has to take them to hospital, take time off work and nurse them, at a time when everyone is already worn out from days of moving belongings away from the water.

Money. Many farming families in Khanu Woralaksaburi and Khlong Khlung have lost crops and household property in one blow. If a house is not restored properly, mold eats into wooden furniture, wardrobes and mattresses, forcing families to throw away more and more, or to strip and repaint walls again and again. Those spiralling costs usually exceed the cost of doing it right the first time.

Time. The weeks after a flood are when farmers must get back to their paddies and cane fields and workers must return to their jobs. Scrubbing the same mold every week because the smell will not go away eats time that should go into rebuilding a livelihood.

Shops and small businesses. Community grocery stores, food stalls and homestays that took on water will lose customers if they reopen with a lingering musty smell. A shop's reputation depends on how well it recovers.

Family and peace of mind. Coming home to a house that still smells of floodwater and shows water lines every day leaves many people stressed and sleepless. Getting the home fresh again is part of emotional recovery, too.

Why the Usual Fixes Are Not Enough

Bleach only works on the surface. Properly diluted bleach can disinfect smooth surfaces like tiles, but it barely reaches into wood grain, porous plaster, bare earth under a stilt house, or gaps your hand cannot reach. Chlorine fumes also irritate the airways, and bleach must never be mixed with products containing ammonia or acids.

Fans speed up drying but do not kill germs. Running fans is good and necessary. But moving air alone does not destroy microbes clinging to surfaces, and it can blow mold spores throughout the house.

Air fresheners only mask the smell. Sprays and scent blocks feel pleasant for a while, but the source of the odour remains. When the fragrance fades, the musty smell returns.

Painting over mold. Many families rush to repaint so the house looks normal again while the walls are still damp and mold remains inside. Within weeks the paint bubbles and black mold reappears.

Sunlight only helps with what you can carry outside. The sun works wonders on small items, but you cannot carry a whole house, its ceilings, walls, built-in cabinets or the space under it into the sunshine. You need a step that reaches the air in every corner of a room.

Post-Flood Ozone Disinfection for Homes in Kamphaeng Phet

World Health Disinfection (WHD) provides residential and building ozone disinfection. WHD is based in Bang Khae, Bangkok 10160, and does not have a branch in Kamphaeng Phet. Homeowners in Khanu Woralaksaburi, Khlong Khlung, Kamphaeng Phet town or other districts can contact the team to plan a service; travel and coverage are confirmed by phone on 065-556-6294 or LINE @whd268, based on the actual job schedule at the time.

How ozone works

Ozone (O3) is oxygen with one extra atom, and it is a strong oxidiser. When a generator releases ozone into a sealed room, the gas spreads into every corner air can reach. It breaks down the structures of viruses, bacteria and mold, and breaks apart odour molecules. Ozone then reverts to ordinary oxygen (O2), so it leaves no chemical residue on surfaces. According to test results certified for the company by Thailand's Department of Medical Sciences and Intertek (UK), the system eliminates viruses, bacteria and mold by 99.99%. See the certification documents for details.

Service steps

1. Assessment. The team asks about house size, number of rooms, how high the water rose and the current condition, by phone or LINE. You can send photos.
2. Preparation. The homeowner removes mud, washes and dries the house and takes out badly damaged items first. The team advises which cabinets, drawers and doors to open.
3. Seal and release ozone. Everyone, including pets and plants, leaves the area. The team closes doors and windows and runs the generator, typically about 30 minutes per zone.
4. Contact time. Ozone is left to work on surfaces and room air for the set period.
5. Rest and ventilation. Doors and windows are opened so ozone can revert to oxygen before anyone re-enters, as instructed by the team.

Key safety rule: ozone treatment is carried out only in an empty, closed space. People, pets and plants must all leave and may return only after the rest and ventilation period. Ozone comes after mud removal, washing and drying; it does not replace cleaning and it does not replace medical care. If anyone has a fever, calf pain, diarrhoea or any unusual symptom after wading through floodwater, see a doctor right away.

10 Reasons Kamphaeng Phet Homes Should Consider Ozone After the Water Drops

1. It reaches where hands cannot. Ozone gas drifts into cabinet gaps, behind furniture, under beds and above ceiling panels, places wiping never fully covers.
2. It tackles odour rising from stilt houses. Wooden houses on stilts, common in Khlong Khlung, often smell from below. Ozone breaks down odour molecules inside sealed rooms.
3. No chemical residue. Ozone turns back into oxygen, which suits homes with young children and older adults. Read more about ozone and chemical residue.
4. It covers bacteria, viruses and mold in a single treatment, according to test results certified for the company.
5. It reduces airborne mold spores, lowering allergy triggers in bedrooms used by children and older relatives.
6. It helps with washed or sun-dried clothes, blankets and books that still smell, when they are spread out inside the treated room.
7. It is quick. Typically about 30 minutes per zone plus ventilation, so families can move back in on schedule.
8. It suits community businesses. Grocery shops, eateries and homestays can reopen without a flood smell. See the ozone service.
9. It is backed by certification from the Department of Medical Sciences and Intertek, as received by the company.
10. A useful promotion. Ozone jobs of 15,000 baht or more come with a free medical-grade disinfectant spray to keep using at home. Ask on the service page.

Before and After a Complete Recovery

Example Case: A Grocery Shop in Khanu Woralaksaburi Ready to Reopen

Example case (an illustrative scenario, not a real customer review)

Nid runs a two-unit wooden shophouse grocery in a community in Khanu Woralaksaburi district. Floodwater came in about knee high and ruined almost everything on the lower shelves. Once it dropped, Nid and her husband spent two days throwing out spoiled stock, shovelling mud, scrubbing the floor with cleaner and leaving the doors open for a through-breeze.

The problem was that the shop is downstairs and the family sleeps upstairs. The musty smell from the wooden floor and shelving drifted up into the bedrooms, and regular customers mentioned that the shop still smelled of floodwater. Nid contacted WHD on LINE, sent photos and gave the floor area. The team advised her to let the wooden floor dry fully for another two or three days, remove food stock and anything sensitive to ozone, and set a date once travel could be confirmed.

On the day, the team split the building into three zones: the shopfront, the storeroom and the upstairs bedrooms. The family went to a relative's house during treatment. Each zone took about 30 minutes, followed by ventilation. "When we came back in, the musty smell that used to hit us at the door was mostly gone, and sleeping upstairs felt easier to breathe," Nid says in this example. The shop reopened with the confidence that every step had been done properly.

Kamphaeng Phet Flood Recovery Checklist: Before and After Ozone

Safety before going in

• Switch off power at the main before entering. If sockets or wiring were under water, have an electrician check before turning anything on.
• Watch for snakes, centipedes and other animals that fled the water into the space under the house, wood piles or the rice granary.
• Wear rubber boots, rubber gloves and a mask, and cover any cuts before cleaning.
• If posts or beams of a wooden house look like they have shifted, have the structure checked first.

Mud out, wash and dry

• Shovel mud out as soon as possible, before it dries hard.
• Wash surfaces with clean water and detergent, then disinfect hard surfaces as public health agencies advise.
• Throw away food, medicine and cosmetics that touched floodwater, including wet rice.
• Mattresses, pillows, rugs and heavily soaked items usually have to go, because they cannot dry before mold sets in.
• Open doors and windows and use fans to push out moisture. Aim to dry things within 24 to 48 hours, as WHO and CDC advise.
• Sweep mud and plant debris from beneath stilt houses to remove odour sources and breeding grounds.

On ozone day

• Everyone leaves, along with pets, chickens, dogs, cats and potted plants.
• Open cabinets, drawers and inner doors as the team advises so ozone spreads evenly.
• Keep windows and vents closed during treatment.
• Return only when the team confirms ventilation is complete.

After ozone

• Keep the house aired out on the first day and watch for spots that stay damp.
• Fix any roof or pipe leaks first, or mold can return.
• Wash hands with soap before every meal and drink clean or boiled water.
• Keep watching everyone's health for several weeks, especially anyone who waded. Fever or calf pain means a trip to the doctor.

FAQ: Ozone Disinfection in Kamphaeng Phet

Does WHD have a branch in Kamphaeng Phet?
No. The office is in Bang Khae, Bangkok, but you can contact the team to plan a service in Khanu Woralaksaburi, Khlong Khlung and other districts of Kamphaeng Phet. Travel and timing are confirmed by phone on 065-556-6294 or LINE @whd268. Same-day arrival cannot be promised.

The water just dropped. Should we do ozone right away?
Not yet. Remove the mud, wash and dry the house first. Ozone is the final step of recovery and does not replace cleaning. If the house is still very wet, mold can come back because the moisture that feeds it is still there.

Can we stay inside during treatment?
No. People, pets and plants must all leave and return only after the rest and ventilation period the team specifies.

How long does it take?
Typically about 30 minutes per zone, plus preparation and ventilation time. Larger homes are divided into several zones.

If we do ozone, do we still need to see a doctor?
Yes, if anyone is unwell. Ozone treats the home, not people. Fever, calf pain, red eyes, diarrhoea or any unusual symptom after wading needs a doctor straight away.

Can a wooden stilt house be treated?
Rooms that can be closed, such as bedrooms, storerooms or an enclosed kitchen extension, can be treated. The open space under the house is handled mainly by clearing mud, washing and sun-drying. The team assesses each house individually.

Is there a promotion?
Ozone jobs of 15,000 baht or more come with a free medical-grade disinfectant spray. Ask on LINE @whd268 for current details.

Ready to Make Your Kamphaeng Phet Home Clean and Easy to Breathe In Again?

Once the mud is out and the house is dry, the next step is dealing with the germs, mold and odour you cannot see. Talk to the WHD team about planning ozone treatment for your home, shop or building.
