Anyone who has visited Mueang Uthai Thani remembers the floating raft houses along the Sakae Krang River and the old riverside temple locals simply call Wat Bot, officially Wat Upothatharam. In early October 2026, the view was very different. River water spread across the temple grounds and the houses around it, standing roughly 50 centimetres to 1 metre deep and rising every day, until a temporary wooden walkway about 800 metres long had to be built so that residents and monks could move around. One day that water will fall. What it leaves behind in monks' quarters, preaching halls and riverside homes is a layer of germs, mold and damp, sewage-like odour that you cannot see. This article explains what a slow river flood like this leaves inside buildings, the right order of recovery, and where ozone disinfection in Uthai Thani fits into that plan.
A typical scenario (an illustrative example, not a statement from any real person)
Auntie Sri lives in a small two-storey wooden house less than a hundred steps from the wall of Wat Bot. Every morning she walks to the temple gate to offer food to the monks, then buys a few side dishes from a riverside stall on the way home. For her, life on the Sakae Krang has always been calm. The river rises and falls with the seasons, and riverside families have lived with that rhythm all their lives.
This year the water behaved differently. On the first day it only touched the lowest step. The next day the yard in front of the house had become a canal. A few days later the water reached the ground floor. Auntie Sri and her son carried the food cabinet, the rice cooker and a box of documents upstairs. The old mattress and the heavy wooden sofa had to stay where they were. The only way to the temple was the wooden walkway that neighbours and local agencies had put together.
When the level finally steadied, she went downstairs and found the floorboards slick with slime, brown tide lines across the wooden walls, and a smell like river mud mixed with stale wastewater. At night her small grandson started coughing and sneezing. Her son said a good wash would sort it out once the water was gone. Auntie Sri was not so sure. The smell was inside the wood, in the air, and in every corner of the house.
According to TNews on 1 October 2026, the situation at Wat Upothatharam (Wat Bot) and the riverside community in Mueang Uthai Thani was as follows:
At national level, the Department of Disaster Prevention and Mitigation (DDPM), as reported by Thai PBS on 4 October 2026, said flooding was still affecting 27 provinces plus Bangkok, covering 154 districts, 1,171,165 households and 3,262,676 people, and warned of renewed heavy rain from 4 to 7 October. These figures change daily. Before planning to move back in or start a deep clean, always check the latest announcements from Uthai Thani province, the municipality and local agencies.
What makes the flood around Wat Bot different from a flash flood in a big city is that it is river water that rises gradually and stays. Water like this has time to soak into timber, brick, plaster and everything stored on the ground floor. The longer it stays, the more moisture builds up inside the structure, and the more opportunity mold and bacteria have to grow once the water is gone.
The community around Wat Bot has features that need careful thought before recovery begins: religious buildings, old timber houses, and a way of life tied to the river. These are the places where germs and odours usually settle after the water recedes.
The sala is where people gather on Buddhist holy days and for merit-making. Soaked floors, mats, carpets, cushions and wooden altar tables hold water deep inside. The surface dries first while the core stays damp, so the musty smell returns every time the day turns hot or it rains again. When many elderly worshippers sit together in an enclosed hall that smells of mold, the risk to their airways rises.
Wooden kuti and temple storerooms often hold robes, chanting books and donated goods stored together. Fabric that was soaked and not dried completely develops black spots and a sour smell within days. Paper and books are an ideal food source for mold, and if everything stays piled in a closed room, mold can spread to items the water never touched.
Many riverside houses in Uthai Thani are older homes built from solid timber, with gaps between floorboards and joints in the wall panels. Muddy water easily flows into these gaps. After the flood, the silt inside them stays damp for a long time and becomes a breeding ground for bacteria and mold that plain rinsing will not remove.
Raft houses float, but their walkways, bathrooms and edge storage still get soaked. Homes right on the riverbank usually flood first and dry last, so moisture stays in their structure longer than in homes further back from the river.
When the river rises, water from drains and septic tanks can back up and mix with the floodwater. This is where the sewage smell and faecal germs in the silt on the floor come from, and it is the main reason all mud must be removed before any other step.
Old temples often contain murals, artworks or historic objects that need specialist care. These should never be washed, scrubbed or treated with chemicals or equipment on impulse, and that includes ozone. If damage or damp appears in parts of historic value, consult the temple and the Fine Arts authorities first. What WHD can help with is ordinary working space: newer halls, monks' quarters, storerooms, kitchens and the homes of the surrounding community.
Floodwater that has run across fields, roads, markets, drains and septic tanks is not clean water. It carries several groups of germs into the house at once, and when it recedes, those germs remain in the mud, the timber gaps, the fabrics and the humid air of each room.
E. coli is the bacterium used as an indicator of faecal contamination. When septic tank and drain water mixes with floodwater, E. coli ends up on floors, kitchen counters, plates and children's toys. Anyone who touches these surfaces and then eats without washing their hands may develop diarrhoea, stomach cramps or nausea. Salmonella spreads through contaminated food and surfaces and can cause gut inflammation, fever and loose stools.
Another disease riverside residents must take seriously is leptospirosis. The Leptospira bacteria live in the urine of animals such as rats and can enter the body through cuts or skin that has been soaked for a long time. People who wade to the temple, to the market, or along parts of the temporary walkway that dip into the water are at risk. Anyone who develops high fever, headache, muscle pain especially in the calves, or red eyes after wading should see a doctor straight away and mention that they walked through floodwater. Do not self-medicate.
Norovirus and rotavirus cause vomiting and diarrhoea and spread easily through hands, surfaces and contaminated food. RSV and influenza spread through droplets and the surfaces hands touch. During floods, people tend to gather in larger groups at temple halls, shelters and relatives' houses. Humid air and exhaustion weaken immunity, so respiratory infections can travel quickly.
Mold can start growing within 24 to 48 hours on wet materials that are not dried, which is guidance health agencies such as the CDC and the World Health Organization repeat often. The timber houses and halls around Wat Bot are full of materials mold loves: wood, curtains, mattresses, mats, paper and books. Airborne spores can trigger allergies, asthma, a blocked nose, coughing, sneezing and eye irritation, particularly in older people, children and anyone with a chronic illness.
The smell riverside families describe as being "stuck in the house" comes partly from compounds released by mold and bacteria as they break down damp materials, and partly from wastewater sediment trapped in floor gaps and pipes. Air freshener or incense only covers the smell for a while. It does not remove the source, and when the heat or humidity returns, so does the odour.
Health. Coughs, sneezing, a blocked nose, rashes, diarrhoea and fever tend to rise after a flood, because everyone moves back at the same time while homes are still damp and silt remains. People who have spent days on heavy cleaning are exhausted, and their defences drop.
Money. If mold is allowed to settle into timber and walls, repair costs climb fast: lifting floors, replacing panels, repainting, and throwing away furniture that could have been saved.
Faith and community. The temple is the heart of the neighbourhood. If halls and quarters still smell damp, merit-making ceremonies and gatherings have to be postponed, and elderly worshippers may hesitate to sit in a space that does not feel clean.
What these methods miss is a step that deals with germs and odour in the air and every corner of the room after cleaning and drying. That is where ozone treatment helps.
The residential and building ozone disinfection service from World Health Disinfection (WHD) uses ozone gas (O3), a strong oxidiser. Ozone breaks down the cell structures of viruses, bacteria and mold and destroys odour molecules, then reverts to oxygen (O2), so no chemical residue is left. Because it is a gas, it spreads through the whole room, into corners, behind cabinets, under beds and into gaps that cloths and brushes cannot reach.
According to test results certified for the company by Thailand's Department of Medical Sciences and Intertek (UK), WHD's ozone system eliminates viruses, bacteria and mold by 99.99%. Details are on the company's certification page.
What everyone should understand: ozone treatment comes after mud removal, washing and drying. It does not replace cleaning, it does not make rotten timber sound again, and it does not replace medical care. Anyone who is unwell must see a doctor.
Key rule: ozone is only used in an empty, closed space. No people, pets or plants inside, and nobody re-enters until the rest and ventilation period is complete.
Service outside Bangkok: WHD is based in Bang Khae, Bangkok, and has no branch in Uthai Thani. Jobs in Mueang Uthai Thani are planned together by phone at 065-556-6294 or LINE @whd268, where the area, date, time and travel cost are confirmed in advance. Same-day arrival cannot be promised, and work only starts once the area is safe, the water has gone and the house is dry enough.
(An illustrative example, not a real customer review)
Tom owns a two-storey timber house his parents built near a temple on the Sakae Krang. The ground floor stayed underwater for several days before the level began to fall. Afterwards, Tom and his relatives spent two full days shovelling mud, hosing down floors and walls, throwing out a soaked mattress and a fabric sofa, and then opening every door and window with fans running for several more days until the floor was dry.
The house looked clean, yet every evening when the windows were shut the musty smell came back. His mother's bedroom upstairs smelled damp from the moisture that had risen for days. Tom sent photos and room sizes to the WHD team on LINE. The team asked him to confirm every room was truly dry, to move the family's Buddha images and keepsakes out first, and then booked a date that fitted the travel plan.
On the day, the family took Tom's mother and the cat to a relative's house. The team treated one zone at a time: the ground floor, the kitchen and the upstairs bedroom. After the rest and ventilation period, the family returned. The evening smell had clearly dropped.
Q: There is still water around Wat Bot. Can we do ozone now?
A: Not yet. Wait until the water recedes, the mud is removed and the space is dry. Ozone works best on clean surfaces with no standing water, and while rain warnings are still active it is wise to follow local announcements first.
Q: Can we stay inside during treatment?
A: No. No people, pets or plants may be in the space, and you return only after the rest and ventilation period.
Q: Can ozone be used in an ordination hall with old murals?
A: We do not recommend it without first consulting conservation specialists and the responsible authority. WHD focuses on ordinary working spaces such as monks' quarters, halls, storerooms and homes.
Q: How long does it take?
A: Typically about 30 minutes per zone, plus preparation and ventilation time. The total depends on the size of the house and the number of rooms.
Q: Does WHD have a team based in Uthai Thani?
A: No. WHD is in Bangkok. Jobs in Uthai Thani are booked in advance by phone at 065-556-6294 or LINE @whd268, with date, time and travel costs confirmed beforehand.
Q: If my house has been treated, do I still need a doctor for a fever after wading?
A: Yes. Ozone deals with germs in the house, not illness in the body. Fever, calf pain, red eyes or diarrhoea after wading need prompt medical attention.
Once the water has gone and the house is dry, the WHD team can help assess and plan ozone treatment for the Sakae Krang riverside community. Send photos and room sizes first for advice.
