For families and temple-goers around Wat Ton Son in Talat Luang subdistrict and Moo 4 in Ban Hae subdistrict, Mueang Ang Thong district, Ang Thong province, the turn from September to October 2026 meant watching the Chao Phraya River almost hour by hour. According to Daily News, an earth dike in Moo 4, Ban Hae gave way on 30 September 2026 after the Chao Phraya Dam increased its discharge, and a few days later river water flowed into Wat Ton Son itself. When the water drops, what stays behind in homes, temple halls and monks' quarters is a mix of germs, mold and damp, musty smells. This article explains what a slow river overflow leaves inside a building, why rinsing the floor and running a fan is not enough, and where ozone disinfection in Ang Thong fits into a safe recovery.
A typical scenario
Aunt La-iad lives in a two-storey wooden house not far from the riverbank in Mueang Ang Thong. Every rainy season she is used to the Chao Phraya rising, but this year felt different. News that the dike at Ban Hae had failed sent neighbours rushing to carry refrigerators, rice bins and mattresses upstairs. Her grandchildren stacked sandbags at the gate, while she kept worrying about the temple where she makes merit, because she had heard the water was already spreading across the temple grounds.
Days later, once the water had drained from under the house, she opened the ground-floor storeroom. The first thing she noticed was the smell: river mud mixed with a stale, closed-in odour that had never been part of her home. A clear tide line ran along the lower wooden walls. A cabinet she had not managed to lift had swollen so badly its doors would not close. Three weeks on, small black spots began to appear in the wall corners and behind the furniture, and her grandson, who has allergies, started coughing and sneezing every time he came downstairs.
The information below comes from dated news reports. Water levels and figures change every day, so readers should always check the latest announcements from local authorities as well.
The 1,523-household figure is a provincial total on the reporting date, not a count for Ban Hae or Talat Luang alone. This article therefore does not give water depths for individual houses and does not estimate any number beyond what was reported. What is clear is that this was overbank flooding from a major river, which usually stands longer than a flash flood and carries fine silt, debris and wastewater from many sources into buildings.
At Wat Ton Son, 20 to 30 centimetres may not sound deep. But in shared buildings such as the main preaching hall, the kitchen, monks' quarters, storerooms for ceremony equipment and public toilets, ankle-to-shin water is enough to soak carpets, mats, floor cushions, curtains, plywood and the lower part of plastered walls, leaving damp that lingers for weeks.
The flooding in Ang Thong is different from the flash floods in the northern hills. The Chao Phraya rises slowly, spills over its banks or seeps through dikes, and then stands on low, flat land for days or weeks. That pattern changes the kind of damage a building suffers.
Ang Thong's life is tied to the Chao Phraya and the Noi rivers. Many communities live along the water, with traditional raised wooden houses, shophouses near the market, single-storey concrete homes and rice fields. Because of this variety, each home needs a recovery plan based on its own materials and ventilation. No single formula fits every house.
When people hear "germs after a flood," many think only of skin rashes or athlete's foot. In reality, floodwater brings several groups of microbes into the home at once, and each causes a different problem.
E. coli is a bacterium that often signals faecal contamination. When floodwater passes through septic tanks and sewer lines, E. coli settles on surfaces, containers and kitchen items. Swallowed through unwashed hands, it can cause diarrhoea, stomach cramps and vomiting. Salmonella is another bacterium linked to contaminated food and water. Leptospira causes leptospirosis, found in water and soil contaminated with animal urine. It enters the body through cuts or skin that has been soaked for a long time, so people who waded for days helping move items out of the temple or cleaning houses face a higher risk.
Norovirus and rotavirus cause diarrhoea and vomiting and spread easily through hands, dishes and contaminated surfaces, especially where people gather, such as evacuation centres or temple kitchens cooking for flood victims. RSV and influenza are respiratory viruses that spread well in rainy, humid weather and crowded settings. Young children and older adults are more likely to become seriously ill.
Public health agencies such as the CDC advise cleaning and drying wet items within 24 to 48 hours to limit mold. In areas where water stands for a long time, as along the Chao Phraya, drying within that window is almost impossible. Mold spores then grow on wooden walls, plaster, ceilings, curtains, mattresses, pillows and wardrobes. Mold does more than make a house look dirty. It can trigger allergies, asthma, a blocked nose, and eye and skin irritation.
Post-flood mustiness comes from volatile compounds released by mold and bacteria as they break down organic matter in the mud, combined with sewage smells soaked into porous materials. These odours lodge inside wood, fabric and foam. Air freshener only hides them for a while. It does not remove the cause.
Older adults, young children, pregnant women, people with chronic illness, allergies or asthma, and anyone with weak immunity should stay away from areas that have not yet been cleaned. In a temple setting, elderly monks who sleep in ground-floor quarters and older devotees who sit in the hall regularly also deserve extra care.
Important: If you develop a high fever, headache, muscle pain (especially in the calves) or red eyes a few days after wading, or have severe diarrhoea or vomiting, see a doctor immediately and mention your flood exposure. Ozone treatment cares for the indoor environment. It is not medical treatment.
Health: Coughing, sneezing, a blocked nose, itchy rashes and diarrhoea often rise in the two or three weeks after the water drops, because people move back into homes that are still damp and still carry germs.
Money: Wooden furniture, mattresses, mats and appliances damaged by water must be replaced. If mold returns after repairs, the household pays a second time.
Time: Many families in Ang Thong farm rice, trade or work in town. Taking days off to scrub a house cuts directly into income.
Community: The temple is the centre of community life, from merit-making to funerals and school activities. If the hall and kitchen still smell musty or show mold, people hesitate to come, or come and feel uneasy.
World Health Disinfection (WHD) provides residential and building ozone disinfection. Ozone (O3) is a strongly oxidising gas. Released into a sealed room, it spreads everywhere, including behind cabinets, under beds and into fabric, and breaks down the structures of viruses, bacteria and mold, as well as odour molecules. Afterwards it reverts to oxygen (O2), so no chemical residue is left behind.
According to the test results the company holds, from Thailand's Department of Medical Sciences and Intertek (UK), ozone treatment eliminated viruses, bacteria and mold at 99.99%.
Empty-room rule: During ozone treatment the room must be empty of people, pets and plants. Re-enter only after the rest and ventilation period the technician gives you.
About travel: WHD is based in Bang Khae, Bangkok 10160, and has no branch in Ang Thong. Service in Mueang Ang Thong and nearby areas is arranged by phone at 065-556-6294 or LINE @whd268. The team confirms the date, time and travel terms when you get in touch. Same-day arrival is not guaranteed.
In addition, ozone jobs worth 15,000 baht or more receive a free medical-grade disinfectant spray under the company's current promotion.
This example case is an illustrative scenario based on common problems. It is not a real customer review.
Somchai owns a raised wooden house in Ban Hae. The open space underneath holds his farming tools, fertiliser sacks and a wooden platform where the family sits in the evening. When the Moo 4 dike failed, water filled the space under the house and stood for several days. The upper floor was never flooded directly, but damp rose through the gaps in the floorboards, and before long a musty smell spread into the bedrooms.
Once the water receded, the family shovelled mud out from under the house, hosed down the posts and ground, threw away wet fertiliser sacks and let sun and wind dry the area for several days. Upstairs they carried mattresses out to air, washed the curtains and wiped the wooden floor with cleaner. Still, the bedroom smell would not go away completely.
Somchai contacted WHD on LINE, sent photos of the rooms and described the size of the house. The team set a date when travel was possible. On the day, the family stayed with relatives while the technician sealed and treated each zone in turn: the bedrooms, the storeroom and the upstairs living area. The rooms then rested and were ventilated as the technician advised before the family returned.
The key point is that ozone came after the mud removal, washing and drying. The family still needed to air the house, control humidity and watch for new mold afterwards.
A riverside temple like Wat Ton Son has several types of building in one compound, and each needs different care. The guidance below is general and can be adapted by temple committees, lay stewards or community volunteers, always after consulting the abbot and those responsible for the temple.
Ozone treatment in temple buildings follows the same rules as a home. The area must be sealed, with no monks, devotees or animals, such as temple dogs and cats, inside during treatment, and the building must rest and be ventilated as the technician advises before reopening. It is best scheduled on a day with no religious duties or ceremonies in that building.
Q: Water entered Wat Ton Son at only 20 to 30 cm. Is ozone really needed?
A: It depends on the condition after cleaning. If everything is washed and dry with no mustiness or mold, it may not be necessary. If carpets, mats, wooden walls or poorly ventilated rooms still smell, ozone can deal with what you cannot see.
Q: Can ozone replace washing the house?
A: No. Ozone is a step after mud removal, washing and drying. If mud or standing water remains, germs can return.
Q: Can we stay inside during treatment?
A: No. The room must be empty of people, pets and plants, and you can return only after the rest and ventilation period the technician gives.
Q: Does WHD have a branch in Ang Thong?
A: No. WHD is based in Bang Khae, Bangkok. Service in Ang Thong is booked by phone at 065-556-6294 or LINE @whd268, and travel is confirmed when you contact the team.
Q: Will mold never come back after ozone?
A: Ozone reduces the germs present at the time of treatment. If the house stays damp or has leaks, mold can return, so humidity control must continue.
Q: I waded for days and now have a fever and calf pain. What should I do?
A: See a doctor immediately and mention your flood exposure, as this may point to leptospirosis. Ozone treatment is not medical care.
Send photos of your rooms and the size of the space to the WHD team for a first assessment. The team will explain the steps, the dates travel is possible and the terms for service in Ang Thong.
