Drinking water is commonly sold in:
Clear plastic bottles
Opaque plastic containers
Consumers generally prefer clear plastic bottles because they can visually inspect the water, which increases confidence in cleanliness and safety.
Product labels must clearly display:
Brand name
Manufacturer address
Net volume
Regulatory registration number
Production details
Compliance with food safety regulations is mandatory.
How Much Investment Is Required?
Starting a bottled water business typically requires an investment of:
THB 300,000 – 1,000,000+
The final budget depends on:
Production capacity
Machinery quality
Automation level
Factory size
Higher output capacity requires larger systems and more advanced equipment.
Step-by-Step Guide to Starting a Drinking Water Business
1. Register with Government Authorities
You must obtain required licenses from relevant regulatory agencies before production.
2. Prepare Production Facility
The facility must meet hygiene and safety standards, including:
Clean processing area
Proper drainage system
Controlled environment
3. Install Water Treatment and Production Equipment
This is the most critical investment part.
4. Prepare Workforce
Staff requirements include:
Production operators
Quality control personnel
Distribution team
5. Develop Marketing and Distribution Plan
Identify:
Target customers
Retail channels
Wholesale partners
Local delivery network
Essential Equipment for Bottled Water Production
Minimum equipment includes:
Water treatment system
Bottle washing machine
Filling machine
Sealing machine
Filling tables for different bottle sizes
PVC or food-grade piping system
Raw Materials
Main water sources:
Tap water
Groundwater
Water must pass quality testing before use.
Bottled Water Production Process (FDA Standard)
According to regulatory guidelines, the production process typically includes:
1. Filtration Process
Sand filter
Resin filter
Activated carbon filter
Reverse Osmosis (RO) system
2. Disinfection Process
Ultraviolet (UV) sterilization
Ozone system
These processes eliminate bacteria and microorganisms.
Example: Household-Scale Water Production Process
Small-scale systems usually follow these steps:
Water passes through Sand Filter
Then to Base Exchange Unit (Resin Filter) to remove hardness
Then through Activated Carbon Filter to remove odor and color
Through Ceramic Bacteria Filter
Finally, through UV sterilization before bottling
RO Drinking Water System
Reverse Osmosis (RO) systems are widely used in modern drinking water factories.
RO systems:
Remove dissolved solids
Eliminate heavy metals
Improve taste
Increase product safety
Example Investment in Equipment Package
Typical starter package (THB 300,000–400,000) may include:
2 water transfer pumps
Manganese filter
Carbon filter
Resin filter
Ceramic filter
UV sterilizer set
Reverse Osmosis (RO) system
Filling heads for 500 ml and 950 ml bottles
Filling system for 20-liter gallons
Tank washing machine
3,000-liter storage tank
Professional water pumps from manufacturers such as LEO are commonly used in water treatment and transfer systems.
Example Cost and Profit Calculation
Fixed Costs (Estimated)
Includes:
Machinery depreciation
Factory rent
Labor cost
Electricity
Assume total fixed cost per year:
THB 600,000
Estimated Annual Production
300,000 bottles per year
Fixed cost per bottle:
600,000 ÷ 300,000 = THB 2 per bottle
Variable Costs
Water cost per bottle:
THB 0.20
Total cost per bottle:
2 + 0.20 = THB 2.20
Revenue Estimation
Selling price per bottle:
THB 4
Annual revenue:
300,000 × 4 = THB 1,200,000
Total production cost:
300,000 × 2.20 = THB 660,000
Estimated net profit before tax:
THB 540,000 per year
Why the Bottled Water Business Remains Attractive in 2026
Essential daily consumption product
Growing health awareness

Scalable production capacity
Strong local distribution opportunities
However, success depends on:
Quality control
Proper water treatment system
Efficient pump and RO design
Strong brand positioning
