What Happened at Soi Khlong Song and Soi Khlong Luang 50

According to a report by the Thai newspaper Naewna on 28 September 2026 at 08.00, water in Khlong Rangsit had risen above the critical level and overflowed onto roads in Khlong Luang district, Pathum Thani, particularly Soi Khlong Song and Soi Khlong Luang 50.

The report described these sois as a pan-shaped dip, with the road lower than the surrounding land. When the canal spilled over, water ran down into the low point, pooled deeply and drained away slowly. Several motorbikes that tried to ride through stalled mid-water, leaving riders to climb off and push.

The report time, eight in the morning, was rush hour, as people were leaving for work and school. That meant many residents were in direct contact with floodwater from the start of the day. These details reflect the situation at the time of the report. Water levels change constantly, so residents should keep following announcements from Khlong Luang district, Pathum Thani province and local authorities.

A Low-Lying Soi Plus an Overflowing Canal: Why the Germ Risk Is High

A pan-shaped soi turns a flood into a bigger hygiene problem than it first appears.

• Water flows in and stays. Everything carried by the water, including rubbish, food waste, dead animals and drain water, collects at the lowest point, which is exactly where people walk.
• Canal water mixes with drain water. When the canal overflows, soi drains cannot cope or flow backwards, so household wastewater and septic overflow can mix into the water on the road.
• It lingers. Because it drains slowly, the water goes stagnant and warm, becoming a breeding ground for germs and smelling worse each day.
• People cross it daily. Unlike a flooded house that the family evacuates, a soi is a route residents still use every morning and evening, so exposure repeats for days.
• Pushing stalled bikes. When an engine dies, the rider has to stand in deep water and push, so legs, feet and hands stay in contact longer, with a risk of slipping or stepping on something sharp.

The result is that germs do not stay in the soi. They ride home on people, shoes, clothes and vehicles into houses, rented rooms and workplaces. Any plan has to deal with both the person and the things that went through the water.

Example Case: One Morning for a Commuter in a Flooded Soi

The following is an illustrative scenario based on common situations in flooded sois. It is not about any real person in the news report.

Ton is a 28-year-old office worker renting a room in a Khlong Luang soi with his wife and their eighteen-month-old son. He rides a motorbike to work every morning. On the day the canal spilled into the soi, he thought he could make it, but at the lowest point the water reached almost to the seat and the engine died. He had to push the bike through murky, foul-smelling water for dozens of metres, and along the way his foot struck something underwater, leaving a scrape.

He came back to the room soaked to the thighs, his canvas shoes waterlogged and his hands wet from the handlebars. His son ran straight over to hug his legs. His wife handed him a towel. His helmet sat on the table next to the baby's bottle, his shoes by the door, and wet footprints trailed across the floor.

This ordinary scene plays out in many homes during floods. From a hygiene point of view, though, it is exactly the moment germs from the soi arrive in the room where a toddler crawls every day.

Germs That Follow Waders Home

The WHO, the US CDC and Thailand's Department of Disease Control agree that contact with floodwater raises the risk of several groups of illness. People who wade through a soi regularly should know these.

Leptospirosis: a leading risk for waders

Leptospira bacteria live in the urine of rats and some other animals. In floods they spread through water and mud and enter the body through cuts, scrapes, skin softened by long soaking, and the eyes and mouth. People who push bikes or walk through water to work every day are directly at risk. The Department of Disease Control advises that if, in the days or weeks after wading, you develop a sudden high fever, headache, muscle pain especially in the calves, or red eyes, see a doctor promptly, mention the wading, and do not self-medicate.

Wound infections and skin problems

Water in a low soi hides broken glass, nails, open drain covers and debris. Small wounds exposed to dirty water can become infected, swollen, hot and pus-filled. Long soaking also causes athlete's-foot-type problems, softened skin and fungal infections between the toes. Wash feet with soap and dry them after every wade.

Faecal bacteria: E. coli and Salmonella

When drain and septic water mix with the flood, gut bacteria end up on hands, shoes, handlebars and clothes. Eating without washing hands, or a toddler touching wet footprints and then their mouth, can cause diarrhoea, stomach pain, vomiting and fever.

Viruses in crowded homes and rooms

During floods, families spend longer in one room or move in with relatives. Norovirus and rotavirus, respiratory viruses such as influenza and RSV, and hand, foot and mouth disease in small children all pass easily through hands and shared surfaces.

Mould from things that never dry

Shoes soaked every day, damp clothes piled up, seats that absorb water and dripping floors breed mould and musty smells. WHO and CDC advise cleaning and drying within 24 to 48 hours to limit mould.

Who is most at risk

• Daily commuters who wade, especially motorbike riders who have to push stalled bikes.
• Toddlers at home, who crawl on floors, hug parents' wet legs and put hands in mouths.
• Older people, with weaker immunity and often chronic conditions.
• People with diabetes, whose foot wounds heal slowly and can become seriously infected.
• Pregnant women, who should avoid wading whenever possible.

Before Any Product: Cut Down Contact with Soi Water

• Where possible, avoid riding through deep water; besides stalling, you risk falling and soaking for longer.
• Wear tall rubber boots rather than canvas shoes or sandals.
• Cover leg and foot wounds with waterproof plasters before leaving.
• Carry dry work shoes in a plastic bag to change into at your destination.
• Avoid spots where you cannot see the ground; there may be open drains or holes.
• Stay away from poles and cables near the water.
• Follow local notices, and consider alternative routes or working from home if you can.

Why Soap or Bleach Alone Is Not Enough for Daily Waders

• Soap is right for skin but does nothing for your belongings. Washing and showering right after wading is essential, yet helmets, handlebars, shoes, door handles and floors touched afterwards remain untreated.
• Bleach is a poor fit for personal gear and vehicles. It can fade or embrittle some materials and corrode metal parts, and in a small rented room with poor ventilation the fumes sting a toddler's nose.
• Mixing risks. Using bleach together with toilet cleaners or ammonia can release dangerous gas.
• It has to be repeated daily. People wading morning and evening need something easy to reuse that does not damage belongings or bother the household with odour.
• No lasting protection. Once dry, surfaces pick up germs again from the next set of wet footprints.

The Solution: CHEMGENE HLD4H, a Medical-Grade Disinfectant for Your Doorstep

According to the product information, CHEMGENE HLD4H is a medical-grade high-level disinfectant made in England and used in hospitals, clinics, laboratories, schools, offices, airports, homes and elderly and child care settings.

Organisms listed: bacteria, fungi and mould, mycobacteria, Salmonella and viruses including influenza H1N1, RSV, norovirus, hand, foot and mouth disease virus and SARS-CoV-2. The product page states it kills within 1 minute, is 99.85% effective against COVID-19, and provides residual surface protection for up to 14 days.

Suited to gear that went through water: per the product information it is non-corrosive to stainless steel, aluminium, rubber, plastic and fibreglass, which covers rubber boots, helmet shells, handlebars and plastic bike parts, aluminium doors and storage boxes. It is biodegradable and stated to be safe for people, pets and medical equipment when used as directed.

Tests and approvals cited: Mahidol University, NHS England, ISO 9001:2015, ISO 13485, SGS, Intertek, CE, and EN 13727, EN 14348, EN 13624 and EN 14476.

Dilution: 1:30, 1:50, 1:60, 1:100 and up to 1:200 per the product information. Choose according to the job and contact time on the label, and keep a ready-mixed, labelled spray bottle by the door.

A "Doorstep Checkpoint" for Khlong Luang Waders

The idea is simple: whatever went through the water stops at the door and never reaches where children play or where people eat and sleep. Every step follows one rule: wash off the dirt first, then apply CHEMGENE HLD4H to cleaned surfaces at the label dilution and contact time.

1. Set up the zone. Place a plastic tray for wet shoes, a separate bucket for wet clothes, soap, clean water, a foot towel and a labelled spray bottle of CHEMGENE HLD4H mixed per the label, out of children's reach.

2. People first. Remove wet shoes and clothes at the door, wash hands, feet and legs with soap and clean water straight away, and shower before picking up children. Check for wounds, clean and cover them. If a wound turns red and swollen or you develop a fever in the following days, see a doctor.

3. Rubber boots. Scrub mud off the outside and soles with soapy water, rinse, then spray CHEMGENE HLD4H all over, leave for the contact time and stand them upside down to dry. Because it does not corrode rubber, per the product information, you can repeat this daily. Canvas shoes soaked in dirty water need a thorough wash and full drying; if smell or mould persists, consider replacing them.

4. Helmets. Wipe the wet outer shell with a soapy cloth, then clean water, then a cloth dampened with CHEMGENE HLD4H mixed per the label over the shell and chin strap. For the inner padding, follow the helmet maker's instructions. Never leave a wet helmet on the dining table or near children's things.

5. Stalled motorbikes. The engine, electrics and oil need a mechanic first; do not keep trying to restart it. For hand-contact parts such as grips, handlebars, the seat and plastic panels, wash off mud with soapy water, wipe with clean water, then wipe with CHEMGENE HLD4H per the label. Never spray into electrics, switches or the engine bay. Lift a soaked seat to air-dry.

6. Flood-soaked clothes. Wash separately from babies' clothes using detergent and clean water, and dry fully in the sun. Do not leave wet clothes overnight, as they breed mould and odour. Wash the bucket, then spray it with CHEMGENE HLD4H per the label.

7. Floors and touch points. Once everyone is in, mop the path from the door with detergent water, then follow with CHEMGENE HLD4H per the label. Wipe door handles, the outside of switches (with a damp cloth, never spraying into them), keys and the table where things are put down. Leave for the contact time and let the floor dry before the toddler crawls on it.

8. If water entered the home. For soi-side houses or rooms where water reached the floor, check electrics first when it recedes, discard food that touched the water, shovel out mud, wash with detergent, then disinfect floors, flooded wall sections, table legs and cupboards with CHEMGENE HLD4H per the label, and ventilate to dry quickly.

10 Reasons Khlong Luang Commuters Keep CHEMGENE HLD4H by the Door

1. High-level, medical-grade, made in England and used in hospitals, per the product information.
2. Broad coverage of bacteria, Salmonella, viruses and mould per the listed organisms. See details.
3. Fast enough for daily life: the product page states it kills within 1 minute, ideal when you are tired and must repeat it every day.
4. Residual protection for up to 14 days per the product information, helpful while the soi stays flooded and wet footprints keep coming in.
5. Non-corrosive to rubber, so boots can be treated again and again.
6. Non-corrosive to plastic and aluminium, suiting helmets, bike parts, doors and windows.
7. Mild smell, far easier than bleach in a small rented room with a toddler.
8. Stated safe for people and pets when used as directed.
9. Biodegradable, so rinse water entering drains and the canal adds less burden.
10. Dilutes up to 1:200, so one bottle lasts a long time for a family using it daily. Order CHEMGENE HLD4H.

Before and After: A Wader's Rented Room

Example Case, Continued: Ton's Room with a Doorstep Checkpoint

Illustrative scenario to explain the steps, not a real customer review.

After that morning, Ton and his wife rearranged the entrance: a plastic tray for a new pair of rubber boots, a bucket for wet clothes, soap, and a spray bottle of CHEMGENE HLD4H mixed per the label on a high shelf away from their son. Each evening Ton strips off wet shoes and clothes at the door, washes his hands and feet, and showers before picking up his son.

He then scrubs his boots with soapy water, sprays them and stands them to dry, and wipes his helmet and handlebars with a cloth dampened with the solution. His wife mops the entry path and follows with disinfectant per the label. The stalled bike went to a mechanic for an engine check. Ton cleaned the scrape on his foot daily until it healed, knowing that fever or calf pain would mean a doctor's visit straight away, and their son keeps playing on a clean floor.
