Nakhon Sawan Flood Update: 9 Districts, 8,995 Households, Water Falling

According to the DDPM situation report with data as of 06:00 on 7 October 2026, published by the Government Public Relations Department and Thai PBS, Nakhon Sawan still had 9 affected districts: Phayuha Khiri, Takhli, Banphot Phisai, Kao Liao, Mueang Nakhon Sawan, Chum Saeng, Tha Tako, Krok Phra and Nong Bua. In total that was 73 sub-districts, 345 villages and 8,995 households, and the report said the water level was falling.

Compared with earlier reports, the trend is clear. On 4 October 2026 the province had 14 affected districts and 13,013 households. On 6 October it was 12 districts and 10,905 households. On 7 October it was 9 districts and 8,995 households. Over the same days, news reports gave the flow at the C.2 gauging station in Nakhon Sawan as 2,119 cubic metres per second on 4 October, 2,038 on 5 October and 1,951 at 06:00 on 6 October, a downward trend.

Nationally, the DDPM reported at 06:00 on 7 October 2026 that floods covered 27 provinces plus Bangkok, 123 districts, 984 sub-districts and 1,154,875 households, affecting more than 3.1 million people (3,160,972). The DDPM gave the cause as heavy to very heavy rain in many areas together with water flowing down from the North. These figures change daily, so readers should follow the latest announcements from the DDPM and Nakhon Sawan province.

The key point is simple: falling water does not mean a home is ready to live in. The days right after the water drops are when families face the heaviest work: shovelling mud, scrubbing floors, throwing out damaged items and deciding how to deal with the germs the flood left behind. Homes in districts that have dropped off the DDPM list still need the same recovery steps, because their walls, floors and furniture sat in water for days.

Example Case: A Riverside Rice-and-Curry Shop in Chum Saeng

The story below is a typical scenario built from situations that are common after floods. It is not a review from any specific customer.

Auntie Daeng has run a rice-and-curry shop from a two-storey wooden shophouse near the riverbank in Chum Saeng for more than twenty years. Downstairs is the shopfront, the kitchen and a storeroom. Upstairs is where she sleeps with her two grandchildren. This year the water came into the shop, so she carried the food cabinet upstairs, but the rice bins, chopping boards and wooden tables had to sit in water for days.

On the day the water fell enough to show the concrete floor, she was up at dawn. Her son, who works in Bangkok, drove home to help. The family shovelled out dozens of buckets of mud, hosed the floor, scrubbed the walls and wiped everything with the floor cleaner they had. Auntie Daeng wanted to reopen as quickly as possible. Regular customers from the neighbourhood and the workers repairing nearby houses kept asking, and the shop is the family's only income.

Three days after the cleanup, problems started to appear one by one. Her younger grandchild had diarrhoea and vomiting. Her son, who had waded through water carrying furniture, had a scrape on his shin that was turning red and swollen. Black spots reappeared on the wooden wall behind the kitchen, even though it had just been scrubbed. And the storeroom still had a damp, musty smell that a fan running all day could not shift. She began to wonder how she could sell food to anyone if her own kitchen was not clean enough.

The family took the grandchild and the son to the hospital first. Then the son called WHD to ask about disinfection spraying for a food shop after a flood. What the family learned was that washing is only the first half of the job. The second half is dealing with the many kinds of germs that floodwater brings and that still cling to places you cannot see.

The Many Germs After the Nakhon Sawan Flood, Group by Group

Floodwater does not bring only water. It mixes what was in drains, septic tanks, animal pens, rice fields and rubbish heaps and spreads it across every floor. When the water recedes, these contaminants stay in the mud and in the film left on surfaces. The World Health Organization (WHO), the US Centers for Disease Control and Prevention (CDC) and Thailand's Department of Disease Control all advise cleaning and then disinfecting surfaces that floodwater has touched. The common germs fall into several broad groups.

Group 1: Bacteria from sewage and faeces

• E. coli (Escherichia coli): a gut bacterium used as the indicator of faecal contamination. Overflowing septic tanks spread it onto floors, lower walls and kitchen tools; some types cause diarrhoea and cramps.
• Salmonella: carried from poultry pens, ponds and animals; causes fever, diarrhoea and cramps, a key risk for food businesses.
• Shigella: causes bacillary dysentery and spreads easily on hands, so it moves fast through families with young children.
• Campylobacter: from poultry and contaminated water; causes diarrhoea, fever and abdominal pain.
• Cholera and other Vibrio bacteria: watched closely by health agencies during floods because they spread through unsafe water and food.

Group 2: Bacteria from soil, standing water and animals

• Leptospira (leptospirosis, rat-urine fever): enters through cuts or soaked skin. Sudden high fever, headache, calf pain and red eyes after wading mean a prompt visit to a doctor.
• Melioidosis (Burkholderia pseudomallei): lives in Thai soil and standing water; people with diabetes or kidney disease are at higher risk.
• Aeromonas and Pseudomonas: freshwater bacteria that can infect soaked wounds.
• Staphylococcus and Streptococcus: skin bacteria that invade scrapes from cleanup work, causing boils and skin infections.
• Legionella: grows in warm still water in tanks and idle pipework; reopened commercial buildings should check their water systems.

Group 3: Gut and liver viruses

• Norovirus: sudden vomiting and diarrhoea; survives well on surfaces and spreads fast in shelters, schools and restaurants.
• Rotavirus: severe diarrhoea and dehydration in young children.
• Hepatitis A: spread through contaminated food and water; an infected food handler can pass it to customers.
• Adenovirus: conjunctivitis, fever, sore throat or diarrhoea in crowded conditions.

Group 4: Respiratory viruses and childhood illnesses

• Influenza, including H1N1, and RSV: spread in damp, crowded spaces among tired people; RSV is riskiest for small children and older adults.
• Hand, foot and mouth disease: passes through toys, tables and shared surfaces in childcare centres.
• COVID-19 (SARS-CoV-2): still worth guarding against when many people clean up or shelter together.

Group 5: Moulds, yeasts and skin fungi

• Aspergillus, Penicillium and Cladosporium: green, grey or black spots on walls, wood and curtains whose spores trigger allergies and asthma.
• Stachybotrys (black mould): grows on gypsum board, wallpaper and plywood that stay wet, a sign of long-term moisture.
• Dermatophytes and Candida: athlete's foot, flood-water foot rot and rashes in people who stand in water all day.

Besides germs, floods leave a musty smell caused by mould and bacteria breaking down organic matter in wet materials. The smell is a warning that moisture and microbes are still present, not just an unpleasant feeling.

Note: this is general information, not a medical diagnosis. Anyone with a fever, muscle pain after wading, severe diarrhoea, a red swollen wound or difficulty breathing should see a doctor promptly.

What Homes and Shops in Nakhon Sawan Face After the Water Drops

Health: young children, older adults, pregnant women and people with diabetes, kidney or lung disease or weak immunity are most at risk, and cleanup workers pick up scrapes that let germs in. Income: every closed day costs a shop money, yet reopening with an unclean kitchen risks sick customers and a reputation built over years. Time and property: scrubbing the same rooms again because smell or mould returns wastes effort, while damp wood and fabric rot faster. Peace of mind: a clear process helps families stop worrying and return to normal life.

Why Washing Alone Is Not Enough

Removing mud and washing with water and detergent must always come first, but washing alone leaves gaps.

1. Washing removes dirt; it is not designed to disinfect. Health agencies say clean first, then disinfect.
2. Brushes miss hidden spots under cabinets, behind counters, in grout and in floorboard joints.
3. Bleach misused. Mud weakens it, and mixing it with toilet cleaner creates irritating gas.
4. Painting over mould on a damp wall only hides it until the paint peels.
5. Air freshener masks the musty smell without fixing the moisture and microbes behind it.
6. A fan dries only the surface; timber cores and plaster stay wet for days.
7. Shared touch points such as handles, switches, rails and the cash counter get forgotten.

For these reasons, systematic disinfection spraying after a thorough wash is a useful extra step that helps make sure surfaces in the home and shop are covered properly.

Post-Flood Disinfection Spraying in Nakhon Sawan by World Health Disinfection

World Health Disinfection (WHD) provides disinfection spraying for homes, buildings and businesses. According to the service information, trained technicians use spraying and/or ULV (Ultra Low Volume) fogging, a very fine mist that helps the disinfectant cover surfaces evenly, including corners that ordinary wiping misses.

The disinfectant is CHEMGENE HLD4H, a medical-grade disinfectant from the United Kingdom containing Benzalkonium Chloride and Didecyldimethylammonium Chloride. According to the service and product information, it is broad-spectrum, covering viruses, bacteria and fungi. The organisms listed on WHD's pages include COVID-19 (SARS-CoV-2), Human Coronavirus 229E, RSV, influenza H1N1 and H5N1, HIV, norovirus, hand, foot and mouth virus, vaccinia virus, mycobacteria, Salmonella and whooping cough (Bordetella pertussis), as well as bacteria and fungi in general. The service page states 99.99% effectiveness, and the product page states 99.85% against COVID-19 within one minute.

For the other organisms mentioned in this article, such as E. coli, Leptospira, Shigella, Vibrio, hepatitis A, rotavirus, melioidosis or black mould, we do not claim organism-specific test results. They belong to the bacteria, virus and fungi groups the product says it covers, and WHO and the CDC advise cleaning and then disinfecting flood-contaminated surfaces. If you need test documents for a specific organism, you can ask WHD directly.

The WHD service page also lists approvals and endorsements from the Department of Medical Sciences, Mahidol University, NHS England and the EN 14476:2013+A2:2019 standard, and names customer types including hospitals, schools, shopping malls, airports, offices, airlines, banks and residential buildings.

How the job works for homes and shops after a flood

1. Enquiry and survey. Call 065-556-6294 or add LINE @whd268. Describe the space, its size, the number of rooms and how high the water came, and send photos so the team can assess it.
2. Finish mud removal and washing first. Spraying comes after shovelling out mud, washing surfaces and discarding damaged materials. The team will tell you what still needs doing before the appointment.
3. Zoning. The space is divided into zones such as kitchen, shopfront, storeroom, bathroom and upstairs, so spraying follows a complete order.
4. People and pets leave. During spraying, residents and pets must leave the zone being treated. Food, dishes and personal items should be packed away.
5. Technicians spray. The team sprays or ULV-fogs the risk points identified in the survey.
6. Wait, then re-enter when the technicians say so. According to the service information, the usual wait is about 30 minutes before the space can be used normally. Always follow the re-entry time the technicians give for your job. Food-contact surfaces in the kitchen should be rinsed with clean water as advised before cooking.

WHD is based in Bang Khae district, Bangkok 10160, and has no branch in Nakhon Sawan. Upcountry jobs are arranged by phone or LINE according to site readiness and the work schedule, so same-day service cannot be guaranteed. It is best to get in touch while you are still clearing mud. Pricing depends on the size and type of the job, and the team will quote after receiving your details. According to the service information, customers also receive a free CHEMGENE spray bottle and WELLGIENIC wet tissues, and a tax invoice is available.

If a musty smell lingers in the air after surface disinfection, you can consider the residential ozone disinfection service as an add-on, which is carried out in a closed space with no people, pets or plants inside.

Post-Flood Disinfection in Bueng Kum: The Latest Situation

Many families in Nakhon Sawan have children working or studying in Bangkok, and quite a few live in the eastern districts such as Bueng Kum, which was also hit by flooding this year. Here is what news reports confirm.

• On 26 September 2026, Bangkok declared all 50 districts disaster zones after continuous heavy rain.
• At 09:27 on 28 September 2026, Siamrath reported 39.0 cm of standing water on Nawamin Road at Soi Santisuk (Nawamin 46), the third highest in Bangkok in that report, with three waterlogged points in Bueng Kum.
• On 29 September 2026, Thai PBS reported 19.3 cm on Nawamin Road Soi 46 (Santisuk) and listed Nawamin Road between Prasert Manukitch and Bang Kapi as a flood point.
• According to the Bangkok Metropolitan Administration on 29 to 30 September 2026, Bueng Kum was one of 15 districts with a high level of impact, together affecting 748 communities. Data from Rocket Media Lab published by Prachatai on 7 October 2026 showed Bueng Kum moving from moderate to high impact.
• For Bangkok as a whole, the DDPM report of 7 October 2026 counted 329,000 affected households, a falling figure. On 5 October, Khlong Saen Saep, Khlong Prawet Burirom and Khlong Prem Prachakorn had dropped somewhat but remained high, and Bangkok was preparing for a new round of rain on 10 to 13 October.

The sources we used do not include a Bueng Kum water reading for 3 to 7 October, so we cannot say whether the area is still flooded or fully dry. Please follow announcements from the Bueng Kum district office and the BMA directly.

Homes in Bueng Kum share the same post-flood risk pattern as homes in Nakhon Sawan. Townhouses, shophouses and dormitories along Nawamin Road where water entered the ground floor need the same sequence: remove mud, wash, dry, then disinfect. Because WHD is based in Bangkok, Bueng Kum jobs can be booked through the same channels: call 065-556-6294 or LINE @whd268.

• Wear rubber boots, gloves, a mask and eye protection, and cover any cuts.
• Watch for snakes, centipedes and scorpions sheltering indoors.

While cleaning

• Shovel out mud, then wash floors and lower walls with detergent.
• Discard food, medicines, cosmetics and soaked wooden chopping boards.
• Remove soaked gypsum, insulation, carpets and cushions; ventilate and dehumidify.
• Never mix bleach with ammonia or toilet cleaners. Drink bottled or boiled water.

Around spraying day

• Pack food, dishes, toys and personal items away; people and pets leave the sprayed zone until the technicians say to return.
• Ventilate afterwards, rinse food-contact surfaces as advised and check idle water tanks and pipes.
• Watch everyone's health for two weeks; fever after wading, diarrhoea or an inflamed wound means seeing a doctor.

FAQ: Post-Flood Disinfection Spraying in Nakhon Sawan

Q: The water in Nakhon Sawan has dropped. Do I still need disinfection?
A: Falling water does not remove germs from the mud and residue. WHO and the CDC advise cleaning and then disinfecting flood-contaminated surfaces. Spraying helps cover hidden spots more evenly than wiping by hand.

Q: Do I need to finish washing first?
A: Yes, always. Mud and organic matter weaken disinfectants, so spraying follows washing; it does not replace it.

Q: How long must we stay out after spraying?
A: People and pets leave the zone during spraying. According to the service information, the usual wait is about 30 minutes, but always follow the time the technicians give for your job.

Q: Does it work against leptospirosis or E. coli?
A: The product is stated to cover bacteria in general, but WHD's pages do not show test results specifically for Leptospira or E. coli. Ask WHD for test data on a particular organism. Either way, anyone with symptoms must see a doctor.

Q: Does WHD have a branch in Nakhon Sawan?
A: No. WHD is based in Bang Khae, Bangkok. Upcountry jobs are scheduled by phone or LINE depending on site readiness and the team's calendar.

Q: Can a restaurant reopen right after spraying?
A: After the re-entry time, rinse food-contact surfaces as advised, check the water supply and discard any ingredients that touched floodwater, then start cooking.

Q: My relatives live in Bueng Kum. Can they book too?
A: Yes. Bueng Kum is in Bangkok; book through 065-556-6294 or LINE @whd268.
