Where Bo Rai, Khao Saming and Khlong Yai Flooded

According to a Matichon report dated 25 September 2026, continuous heavy rain flooded roads in the Moo 4 and Moo 7 lanes of Bo Phloi subdistrict and in Nong Bon subdistrict, Bo Rai district, as well as Moo 7 of Sato subdistrict, Khao Saming district. The report said about 30 households were cut off and had to be evacuated by flat-bottomed boat. At the Sato bridge, the water level stood at 8 metres, only 1 metre below the critical point. Sukhumvit Road in Khlong Yai district was also flooded to a depth of around 60 to 80 centimetres.

These figures describe the situation on the date of the report only. The report does not list damaged homes by village or give water depths inside individual houses, so this article does not guess at further numbers. Please follow the latest announcements from the Bo Rai and Khao Saming district offices, subdistrict administrative organisations and Trat's disaster prevention and mitigation office, because flood conditions change constantly.

For the national picture, Daily News reported DDPM data as of 06:00 on 5 October 2026: 26 provinces plus Bangkok affected, 1,270,151 households and 3,519,416 people. Thai PBS reported that ONWR warned of heavy rain and flash floods from 5 to 7 October in the north and parts of the south. That warning did not name Trat, but it shows the rainy season is not over, so home recovery plans should allow for another round of rain.

What Families Cut Off in Bo Rai and Khao Saming Face When They Return

Bo Rai and Khao Saming are districts where many families grow fruit and rubber. Homes are spread along village roads and canals: wooden houses, single-storey and two-storey concrete houses, and houses with a small grocery shop at the front. When the road into a village goes under water and cars cannot get through, families who are cut off often leave in a hurry, taking only essentials and important documents. Everything else stays behind in a sealed house: food in a fridge that has lost power, damp laundry, rubbish bins and anything left on the floor.

That makes the problems after the water recedes more complicated than in a home where someone stayed. Food rotting in the fridge and kitchen produces a strong smell and becomes a breeding ground for bacteria. A closed house with no airflow traps moisture, so mold grows quickly. If water entered the house, the silt left on the floor carries flood germs with it. For anyone running a small shop, goods on lower shelves may be damaged and need sorting before the shop can reopen.

In Khlong Yai, Sukhumvit Road is the main route lined with shops, homes and businesses. Water of 60 to 80 centimetres on that road, as reported, means low buildings along it could take water inside. Road runoff often carries oil, dust and dirt from drains, which leaves more staining and odour than plain rainwater.

Every Kind of Germ the Trat Flood Can Carry

The WHO, the CDC and Thailand's Department of Disease Control all warn that after a flood people should watch for water and food borne illness, skin infections and breathing problems caused by mold. Here are the groups of germs residents of Bo Rai, Khao Saming and Khlong Yai should know about.

Bacteria From Water and Sewage

Floodwater that runs across roads, orchards and drains is often contaminated with bacteria from human and animal waste, such as E. coli and Salmonella, which cause diarrhoea, stomach pain, vomiting and food poisoning. They cling to floors, kitchen counters and dishes that touched the water. Another important disease in orchards and rural areas is leptospirosis, known locally as rat urine disease. The bacteria come from the urine of rats and some other animals and enter through cuts or skin that has been soaked for a long time. Typical signs are a sudden high fever, headache and muscle pain, especially in the calves. Anyone with these symptoms after wading must see a doctor quickly and say they waded through floodwater.

Stomach and Respiratory Viruses

Norovirus and rotavirus spread through contaminated food and water and cause vomiting and severe diarrhoea. Young children are especially at risk of dehydration. Influenza and RSV spread easily when many people stay together at evacuation points or in crowded relatives' homes. When families go home, viruses can travel on clothing, blankets and personal belongings, so cleaning what comes back from the evacuation point matters too.

Mold in a House Left Closed

Health agencies advise cleaning and drying a home within about 24 to 48 hours after the water recedes to reduce mold growth. Houses that were cut off and could not be reached for days usually miss that window. Mold then grows on walls, ceilings, wooden cupboards, curtains and mattresses. Airborne spores make people sneeze, block their noses, irritate their eyes and can trigger asthma and allergy flare-ups.

Musty, Rotting Food and Sewage Odours

A house closed for days usually has layers of smell: musty odour from mold, rotting food from a fridge without power, mud and sewage from pipes or septic tanks. Odour molecules soak into porous materials such as fabric, wood and tile grout, so washing the floor alone leaves a smell that returns every time the doors and windows are closed.

Who in Bo Rai and Khao Saming Households Needs Extra Care

Older people, whose immunity is weaker and who often have chronic conditions; young children, who play on the floor and put things in their mouths; pregnant women, who should avoid mud and strong cleaning chemicals; and anyone with a chronic illness or weakened immune system should return only once the house is clean and dry. They should not be the ones doing the early clean-up.

Equally at risk are the people who wade in first to clear the house, and those who head straight back to orchards and rubber plots, often with small cuts on their hands and feet. Wear rubber boots and gloves, wash hands and feet with soap after every contact with floodwater, and pay attention to your own health for two weeks afterwards.

The Impact on Families in Bo Rai, Khao Saming and Khlong Yai, Trat

Health: Diarrhoea, rashes, athlete's foot, infected cuts and mold allergies are common in the first week back. A damp, smelly house means poor sleep, lingering coughs and fatigue.

Cost: Besides home repairs, orchard families may need to invest in their plots at the same time, and shops must throw away damaged stock. If mold spreads until ceilings or furniture must be replaced, the bill rises again.

Time and access: While village roads are still wet or damaged, carrying out waste and bringing in cleaning equipment is harder. Recovery drags on, and repeating work because the smell will not go away wastes even more time.

Shops on Sukhumvit Road, Khlong Yai: Restaurants, shops and guesthouses on the main road rely on passing customers. Reopening with a musty smell or flood stains directly affects customer confidence.

Family and wellbeing: Leaving your own home by boat and then returning to damp rooms and ruined belongings is hard. Making the home pleasant and easy to breathe in again helps everyone get back on their feet sooner.

Why Common Fixes Fall Short in a House Left Closed for Days

Bleach everywhere: Bleach works on hard surfaces once the mud is gone, but it does not penetrate wood, fabric or foam, and it does nothing for odours trapped in materials. Never mix it with ammonia or some toilet cleaners, because dangerous gas is released.

Fans alone: The surface may dry, but moisture remains in walls, under floors and inside mattresses, and fans spread mold spores to other rooms.

Air freshener: A pleasant scent hides a musty smell for a while but does not remove its source, so the old smell soon returns.

Painting over mold: The wall looks new, but if it is still damp, mold pushes stains through again and the paint blisters or peels.

Washing the fridge and using it straight away: A fridge that sat without power with rotting food inside needs all food thrown out, every part washed and time to air dry. Odour trapped in the door seals takes time to deal with, so do not rush to restock it.

Ozone Disinfection in Bo Rai and Khao Saming, Trat with WHD: The Step After Cleaning and Drying

World Health Disinfection (WHD) provides residential and building ozone disinfection for homes, condominiums, shops, offices, guesthouses, schools and factories. Ozone (O3) is released into a closed, empty space. As a strong oxidiser, it spreads throughout the room, reaches corners and gaps that wiping cannot, breaks down the structures of viruses, bacteria and mold, and breaks down odour molecules. It then reverts to oxygen (O2), leaving no chemical residue.

According to test results certified for the company, carried out by the Department of Medical Sciences and Intertek (UK), the process eliminates viruses, bacteria and mold by 99.99%. Even so, ozone must come only after the mud is removed, the house washed, spoiled items discarded and the space dried. Ozone does not replace cleaning, does not dry soaked materials and does not replace a doctor's care.

How the Work Is Done

1. Contact and assessment: Tell us by phone or LINE where your home is in Bo Rai, Khao Saming or Khlong Yai, its size, number of rooms and condition, with photos.
2. Room preparation: People, pets and plants leave the area. Doors and windows are closed, and food and medicines are removed.
3. Ozone release: The team sets up the equipment and controls concentration in each zone.
4. Contact time: Typically about 30 minutes per zone, depending on room size and condition.
5. Rest and ventilation: The ozone breaks down, the space is ventilated as the technician advises, and only then do people go back in.

WHD is based in Bang Khae, Bangkok 10160, and has no branch in Trat. Service in Bo Rai, Khao Saming and Khlong Yai is arranged by phone at 065-556-6294 or LINE @whd268. The team confirms travel, coverage and dates when you get in touch. We do not promise same-day arrival, so contact us as soon as you start cleaning so that planning can begin in time.

When Is a House Ready for Ozone After the Road Reopens?

A house you have only just been able to reach should not be treated on the first day. The right order is to check that the structure and electrics are safe, throw out rotten food and anything that cannot be saved, shovel out mud, wash surfaces and ventilate until dry. Once the house reaches that state, ozone can deal with lingering germs and smells in a way that is worth the money. Treating a house that still has mud and standing water leaves the source of the problem in place, and the smell comes back.

Because the water at the Sato bridge came close to its critical level according to the report, families living near the river should check official warnings before booking. If heavy rain is forecast, start with the rooms used every day and finish the rest when conditions settle. The WHD team can help plan the order of rooms and the timing for each home.

Example Case: A Home With a Grocery Shop in Bo Phloi After Evacuation

Note: this example case is put together from situations that commonly follow floods. It is not about a real person and it is not a customer review.

Picture Sunee, who runs a small grocery shop at the front of her house in a village in Bo Phloi subdistrict. When heavy rain floods the lane and cars can no longer get in or out, Sunee, her primary-school son and her father, who has diabetes, are evacuated by flat-bottomed boat with their neighbours, leaving stock and belongings behind.

Several days later, when the road is usable again, Sunee opens the house. The shop fridge has been without power for a long time, milk and fresh food have spoiled and the smell fills the house. Silt covers the floor, boxes on the bottom shelves are wet and the storeroom wall is showing mold spots. Sunee leaves her father and son with relatives and asks two cousins to help. They switch off the power so an electrician can check it, throw out food and any stock that touched water, shovel out silt, wash floors and shelves, wash every part of the fridge and leave doors and windows open for several days.

The house is dry, but the storeroom and bedroom still smell musty. Sunee could contact WHD on LINE, send photos and give her location in Bo Rai. The team would advise her to wipe off visible mold first and then plan ozone treatment for the shop, storeroom and bedroom. Everyone stays outside during treatment and the rest period, and the house is ventilated as the technician advises before the shop reopens. If her son develops diarrhoea or her father a fever, Sunee takes them to a doctor at once, because ozone is not a treatment for illness.
