The Flood Situation in Bang Bon: What the Official Reports Say

• Bangkok overall: on 25 to 26 September 2026 Bangkok received more than 300 mm of rain in about 48 hours, and on 26 September all 50 districts were declared disaster areas, according to Thai PBS and Malay Mail.
• All four Bang Bon subdistricts: on 29 September 2026 the DDPM declared Khlong Bang Bon, Khlong Bang Phran, Bang Bon Nuea and Bang Bon Tai as flood assistance zones, with the hazard dated from 25 September, according to Thai PBS.
• The wider picture: the same day the DDPM listed 38 districts and 118 subdistricts of Bangkok as assistance zones, and on 6 October 2026 it reported 329,000 Bangkok households affected.

To be clear: in the sources we checked there were no street-level water depth reports for Bang Bon, and reports suggested the Thonburi side overall was hit less hard than the east. We are not saying every school in Bang Bon was deeply flooded. But all four subdistricts being listed shows the area was genuinely affected by the heavy rain. What can realistically happen to school buildings in a district of canals and low ground is water standing in yards and the soi outside, drains backing up into toilets and kitchens, seepage into ground-floor classrooms, and humidity trapped in buildings closed for days. Information changes daily, so check notices from the BMA, the DDPM and your school's supervising agency.

Why Kindergartens and Nurseries in Bang Bon Need More Care Than Ordinary Buildings

Bang Bon has canal-side communities, housing estates, small factories and many working families. Community childcare centres, private kindergartens and small nurseries in the sois are essential for parents who leave for work early. When a centre stays closed, parents cannot work; when it reopens before the building is ready, children are at risk.

Buildings that care for young children differ from homes and offices. Many children spend all day together in one room, eating, napping and playing in the same space, so germs from one child reach many others quickly. Children this age put things in their mouths, crawl, sit on the floor and cannot wash their hands well. Kindergarten rooms are full of absorbent items: nap mats, mattresses, blankets, rugs, rubber floor tiles, plush toys, foam blocks, reading corners and paper artwork. And many centres are converted shophouses or homes with few windows and limited ventilation.

When such a building meets heavy rain, standing water and lasting humidity, the result is not just a smell but an environment that suits mold and many germs, in a space shared by the most vulnerable people. That is why a search for ozone for kindergartens and nurseries in Bang Bon should come with a complete plan, not just a quick spray before reopening.

Germs Kindergartens and Nurseries Must Watch After Waterlogging

Hand, foot and mouth disease

Hand, foot and mouth disease is caused by enteroviruses and is common in young children, especially during the rainy season. It spreads through saliva, nasal discharge, blister fluid and stool, as well as contaminated toys and surfaces. Children develop fever, mouth sores and spots on the hands, feet or bottom. It is a main reason childcare centres close for cleaning during outbreaks. Thailand's Department of Disease Control advises regular cleaning of toys and surfaces and keeping sick children home until they recover.

RSV and influenza

RSV circulates heavily in the rainy season and is an important cause of respiratory infection in young children. It spreads through droplets and by touching contaminated surfaces and then the nose or eyes. Influenza circulates at the same time, so closed, air-conditioned classrooms with many children are a transmission point to watch.

Gut viruses and bacteria

Norovirus and rotavirus cause diarrhoea and vomiting and spread very easily through hands and surfaces. Water that backs up from drains or stands in the school yard may carry faecal bacteria such as E. coli and Salmonella, so kitchens and toilets that took drain water need thorough cleaning and disinfection before reopening. Water mixed with rat urine also carries a leptospirosis risk for teachers and caretakers who wade while cleaning.

Mold and musty odours

Mold can grow within 24 to 48 hours after materials get wet, as WHO and CDC guidance notes. In nurseries it typically appears on stacked nap mats, under rubber floor tiles, along ground-floor walls, on bookshelves and inside air conditioners. Spores trigger allergies and asthma in children, and the musty smell teachers and parents notice when opening the classroom door is a sign the source is still there.

Which Children Are Most at Risk, and What Centres Should Do When a Child Is Ill

Children under three, those born prematurely, those with heart or lung conditions, asthma or allergies, and children recently recovered from illness may get sicker than others. Pregnant teachers and older carers should take care too.

Centres should screen children every morning for fever, mouth sores, spots on hands and feet, coughing or fast breathing. If found, ask parents to take the child to a doctor and keep them home as advised. A child who is breathing hard, wheezing, drowsy, refusing fluids or having a seizure needs a doctor immediately. Teachers or caretakers who waded and then develop fever or calf pain must tell the doctor about the wading. Ozone treatment manages the building environment; it is not medical treatment and does not replace screening or seeing a doctor.

The Impact on Schools, Teachers and Families in Bang Bon if a Centre Reopens Too Soon

Children's health: a cluster of colds, diarrhoea or hand, foot and mouth cases after reopening may force the centre to close again, which is harder on everyone.

Parent confidence: parents notice quickly and share in LINE groups. A musty classroom or a single mold patch on a wall can become the topic of the whole group.

Income and costs: private kindergartens and nurseries lose income while closed and still pay for new mats, toys, rugs and repairs. A second closure adds to the burden.

Teacher workload: teachers clean, care for children and answer parents at the same time. Without a clear plan, all of it falls on a few people.

Working families: many Bang Bon parents work in factories or for daily wages. A long closure means lost income straight away.

Why Washing and Spraying Alone Is Not Enough for a Childcare Centre

Mopping with disinfectant: essential and must be done, but it covers only reachable surfaces, not under shelves, behind mat cupboards, ceiling corners or the air.

Using strong bleach to be sure: chlorine lingering in a closed room irritates children's airways, and mixed with toilet cleaners or ammonia it forms dangerous gases. Use it only at the correct dilution.

Fans and air conditioning to dry the room: they help drying, but fans spread spores and an uncleaned air conditioner blows mold from its coil into the room every school day.

Air freshener before parents arrive: it masks the smell for minutes and fragrance can trigger allergies in children.

Repainting over mold: the room looks bright, but if the wall is still damp mold returns within weeks, and fresh paint fumes in a closed room are not ideal for young children.

Surface cleaning is the foundation, but a childcare centre needs one more step that covers the air and every corner of the room. That is where ozone adds value, after cleaning and drying are complete.

Ozone for Kindergartens and Nurseries in Bang Bon With WHD: Process and Timing With No Children Present

Ozone (O3) is a reactive gas. Released in a closed room it spreads through the air, under shelves, behind cupboards, around tables and chairs and over toys, breaking down viruses, bacteria and mold and splitting odour molecules, then reverting to oxygen (O2) with no chemical residue on desks or toys. According to the test results the company has certified, from Thailand's Department of Medical Sciences and Intertek (UK), WHD's ozone system eliminates viruses, bacteria and mold by 99.99%, and WHD serves many building types including schools.

The rule that always applies: during ozone treatment the building or zone must contain no children, no teachers, no caretakers, no pets and no plants. Ozone at disinfecting concentrations irritates the lungs and airways. Children must not be in the building, and may return only after the rest and ventilation period set by the technician.

The right timing for a childcare centre

• Before reopening for the first time after the water recedes: the best moment, because the building is empty and can be cleaned, dried and ozone-treated room by room in one day.
• Weekends and holidays: for centres already open, book on a day with no children at all.
• After school in the evening: possible if every child has gone home and there is enough time for rest and ventilation before the next morning.
• After a contagious illness case: once the centre has closed as advised by health authorities, clean according to Department of Disease Control guidance first, then add ozone.

The process

1. Assessment by phone or LINE: send the floor plan, number of rooms, photos of smelly or moldy spots and which rooms took water.
2. Prepare: remove mats, mattresses and heavily contaminated items; wash floors, lower walls, toilets and kitchen; have air conditioners cleaned; dry the building as much as possible.
3. Open cupboards, drawers and toy boxes so ozone reaches every corner.
4. Confirm the building is empty of people, pets and plants.
5. Treat zone by zone: a typical cycle takes about 30 minutes per zone, depending on room size.
6. Rest and ventilate: open windows and doors for the time set by the technician; teachers check first, then children return.

Ozone always comes after mud removal, washing and drying. It does not replace standard cleaning, discarding soaked mats or fixing pipes and leaks.

Kindergarten Equipment: What to Wash and What to Discard Before Ozone

Nap mats and mattresses: if standing water or drain water reached the foam inside, throw them away. Mats with vinyl or plastic covers that stayed dry can be wiped, air-dried and laid out flat, not stacked, during treatment.

Plastic toys and building blocks: wash with soapy water, rinse and air-dry. After ozone and ventilation, rinse mouthed toys again with clean water.

Plush toys, blankets and pillows: wash hot per the label and dry until the filling is completely dry. Discard items soaked in dirty water that cannot be washed.

Rubber floor tiles and rugs: lift every tile, wash both sides and dry; the floor beneath must be dry before relaying. Large rugs that were submerged should be replaced.

Storybooks and paper work: discard books wet enough to grow mold.

Kitchen and food containers: clean and sanitise to food hygiene standards, discard food touched by floodwater and check fridges if power was cut.

Children's toilets: clean toilets, basins and floors thoroughly and check drains that backed up.

10 Reasons Bang Bon Childcare Centres Should Use Ozone Before Children Return

1. It covers the whole room, air and corners that mopping and wiping cannot reach.
2. It deals with viruses, bacteria and mold, 99.99% according to the company's certified tests. See the ozone service details
3. It removes musty odours at the source, so parents open the classroom door to fresh air.
4. No chemical residue on desks, toys or mats, because ozone reverts to oxygen.
5. A whole building in one day, about 30 minutes per zone plus ventilation.
6. It can be booked on holidays or after school, so children are never present and no extra closure days are needed.
7. It supports hand, foot and mouth and RSV prevention alongside screening and handwashing.
8. It builds parent confidence that both surfaces and air were handled.
9. Clear safety steps: empty building, sealed, rest and ventilate before entry. Plan ozone for your school

Before and After Ozone at a Childcare Centre

Example Case: A Nursery in a Two-Unit Shophouse in Bang Bon Tai

A typical scenario. Names and details are illustrative, not a verified customer review.

Teacher Oy runs a small nursery in a two-unit shophouse in a soi of Bang Bon Tai, caring for about twenty children aged one to three. The ground floor holds the play and nap rooms; upstairs is the activity room. On a night of heavy rain at the end of September, water stood in the soi and backed up through the children's toilet drain. Only a little entered the ground floor, but it seeped under every rubber floor tile, and Teacher Oy closed temporarily.

The teachers swept and mopped, but three days later, lifting the tiles revealed dark stains along almost every seam, stacked nap mats smelled musty and the air conditioner smelled sour. Parents asked in the LINE group when the nursery would reopen and wanted confirmation the rooms were safe.

After talking with WHD on LINE, Teacher Oy reorganised the work. She discarded the stained tiles and the mats with wet foam, washed floors and lower walls, washed every toy, laundered blankets and plush toys, had all air conditioners cleaned and a plumber check the toilet drain, and ran windows and a dehumidifier for two days. She then booked ozone for both floors on a Sunday when no children or teachers were in the building.

On Monday morning the teachers checked first and the musty smell was gone. Teacher Oy laid out new mats, rinsed mouthed toys again with clean water and posted a step-by-step explanation in the LINE group, adding that every child would be screened each morning. Most parents brought their children back that week. Her lesson: being transparent about the steps matters as much as the cleaning itself.

Checklist for Reopening a Bang Bon Childcare Centre, Before and After Ozone

Before ozone

• Photograph damage and keep repair receipts in case you apply for help in a DDPM assistance zone
• Teachers and caretakers wear rubber gloves, boots and masks while cleaning
• Discard mats, mattresses, rugs and toys soaked in dirty water that cannot be cleaned
• Wash floors, lower walls, toilets and kitchen, then dry completely
• Wash every toy and launder fabrics and plush toys
• Clean all air conditioners and check drains that backed up
• Open cupboards, drawers and toy boxes and lay stored mats flat
• Confirm no children, teachers, pets or plants will be inside on treatment day

After ozone

• Wait for the full rest and ventilation period; teachers check first
• Rinse mouthed toys with clean water again

FAQ: Ozone for Kindergartens and Nurseries in Bang Bon

Q: Can we run ozone while children are in another room?
A: Not recommended. Treat only when the building or zone is completely empty of children, teachers, pets and plants, with no way for ozone to leak into occupied areas. The best times are before reopening, on holidays, or after every child has gone home.

Q: After ozone, can we skip cleaning according to Department of Disease Control guidance?
A: No. Cleaning surfaces and toys according to public health guidance is always required. Ozone is an extra step that covers the air and corners after cleaning.

Q: Does ozone prevent hand, foot and mouth disease?
A: It reduces germs in the air and on surfaces at the time of treatment, but it cannot stop infection brought in by a newly sick child. Morning screening, keeping sick children home and handwashing remain the most important measures.

Q: How long does it take? Can we open the next day?
A: About 30 minutes per zone plus rest and ventilation. Most small centres finish in a day, provided cleaning and drying are complete beforehand. The team will confirm timing when booking.

Q: Can community childcare centres use the service?
A: Yes. WHD serves homes, condos, offices and schools. Contact us for a quotation and supporting documents.
