The growing demand for clean, safe drinking water in the Philippines has created strong opportunities for businesses that sell purified water. While complying with national sanitation standards, neighborhood water refilling stations often provide cheaper potable water than bottled mineral water from supermarkets, especially as the cost of home water filters continues to rise.
Why water refilling stations are growing
A combination of high urban population, rising demand for safe drinking water, and easy accessibility makes the water refilling station business a popular option that can generate a steady stream of income.
Before starting, aspiring owners must assess demand, competition, growth opportunities, and overall feasibility. This includes shop location and rent, utilities, customer foot traffic, equipment, water supply, and the cost of hiring and training staff.
Like many businesses, you can either buy a franchise or build your own brand from scratch. Each option has its own pros and cons in terms of cost, control, and support.
The current water refilling landscape
There are now more than 3,000 water refilling stations nationwide. They sell purified water with quality comparable to bottled water at a lower price.
In Metro Manila, most stations are connected to Maynilad Water Company or Manila Water Company as their raw water source. In other areas, stations may rely on local water utilities or deep wells.
Typical stations produce 3,000 to 12,000 liters of purified water daily. Customers usually bring 5-gallon containers, and many shops now offer delivery services, which are convenient but add costs for vehicles, fuel, and drivers.
How to start your own water refilling station
1. Create a business plan
A solid business plan helps you understand if the business is viable and sustainable.
- How much do you need for equipment, permits and licenses, manpower, shop lease, utilities, and marketing?
- Do you have enough capital? If not, can you service bank loans until the business becomes profitable?
- What type of product will you sell: alkaline, purified, or mineral water?
- Is there room to enter the market given existing competitors?
- When do you expect to break even and start making profit?
- What risks might you face (equipment breakdown, water supply issues, etc.)?
2. Choose a suitable location
Pick a location that is visible to your target customers and appropriate for a clean water business. Avoid areas near garbage dumps or other sources of contamination.
Ideal sites are close to apartments, subdivisions, schools, and business districts, where residents and offices will likely need regular refills.
3. Find a reliable equipment supplier
If you are franchising, the franchisor usually supplies the equipment. If not, choose a supplier that can design a layout for your space and advise on access to water and electrical supply, as well as workflow for staff and customers.
Check the supplier’s relationship with manufacturers, spare parts availability, and access to trained technicians for troubleshooting and maintenance.
4. Register your water distribution business
Legal registration proves your business is authorized to sell drinking water.
- Secure a business name from the Department of Trade and Industry (DTI).
- Apply at your municipal or city hall for a mayor’s permit and sanitary inspection.
- Expect inspection of your water source and lab analysis (physical, chemical, bacteriological).
- Have building and electrical plans signed by authorized professionals such as sanitary engineers.
- Apply with the BIR (Form 0506) to authorize printing of official receipts and pay the required fees.
5. Buy additional equipment and supplies
Beyond the main purification system, prepare complementary supplies before opening:
- Water containers and gallon bottles
- Sanitizing soap and cleaning materials
- Cap seals and heat gun
- Sticker labels and basic shop tools
6. Hire and train your staff
Hire staff early enough to train them on equipment operation, daily tasks, sanitation procedures, and customer service. A well-trained team helps prevent errors and ensures consistent water quality.
7. Promote your business
Reach out to nearby businesses such as carinderias, restaurants, and offices and offer bulk discounts.
Consider value-added services like free pickup and delivery for bulk orders or extended operating hours. Anticipate peak demand periods such as summer or town fiestas and prepare sufficient supply and delivery capacity.
Water purification process
Customers choose water refilling stations for one main reason: clean, safe drinking water. To achieve this, stations use high-performance machines with multiple treatment steps:
- Multi-media sediment filter – Removes sediments such as rust, sand, and other fine particles using multiple filters.
- Ion exchanger – Replaces hard minerals with softer ones to reduce water hardness.
- Activated carbon filter – Removes organic chemicals, herbicides, pesticides, bad odors, and unpleasant taste.
- Reverse osmosis membrane – The core of the system; removes inorganic minerals, bacteria, and viruses while retaining oxygen content. With a pore size of less than 0.05 micrometre, it can produce water with total dissolved solids (TDS) below 10 ppm but rejects about 50% of the raw water volume.
- Post-carbon filter – Further polishes and improves the taste of water.
- Ultraviolet lamp – Kills disease-causing micro-organisms.
- Ozone generator – Inhibits bacterial growth in the storage tank and extends the product’s shelf life.
Regulatory bodies and industry organizations
Several government agencies and private organizations oversee licensing, monitoring, and standards for water refilling stations.
- Department of Health (DOH) – Main government agency responsible for public health. The Sanitation Code mandates DOH to protect drinking water quality and issue implementing rules and regulations, including sanitary standards for water refilling stations.
- Center for Health Development (CHD) – DOH’s regional arm. Provides technical assistance to LGUs and monitors DOH program implementation, including water quality and sanitation. Issues initial and operational permits for water refilling stations.
- Local Government Units (LGUs) – Under Presidential Decree 856, LGUs issue sanitary permits, sanitary clearances, health certificates, certificates of potability, drinking water site clearances, and closure orders when necessary, and conduct sanitary inspections.
- Water Quality Association of the Philippines Inc. (WQAP) – A private association of firms engaged in manufacturing and distributing water refilling station equipment and water treatment technologies for various applications. Around 85% of its 250 members operate water refilling stations.
- Association of Water Refilling Entrepreneurs (AWARE) – Focuses on business management concerns of its member water refilling entrepreneurs.
Quality control requirements
Source water and product water are regularly monitored by local health offices. National standards for drinking water define 54 parameters that must be met.
Only DOH-accredited laboratories can conduct water testing and analysis. Monitoring frequency typically includes:
- Bacteriological quality – at least monthly
- Physical quality – at least every six months
- Chemical quality – at least every six months
- Biological quality – at least once a year
- Radioactive contaminants – monitored only when there is significant radiation input from the environment
Space and manpower requirements
Space requirements
Water refilling stations do not need large areas, which helps reduce rental costs. A space of 20–25 square meters is often enough for:
- Refilling and selling area
- Enclosed water purification room
- Container washing and sanitizing area
- Storage for empty and refilled containers
- Source water storage facility
- Toilet and small office
About five employees are usually sufficient to operate a typical station.
Manpower requirements
A basic staffing setup can include:
- Manager – Oversees daily operations, customer service, and adherence to purification standards (often part-time, around four hours a day).
- Accountant/Bookkeeper – Handles finances, tax compliance, and sales records.
- Front-liners/Store Assistants – Receive orders, refill containers, handle payments, and coordinate deliveries. The number depends on workload.
- Technical Personnel – Maintains and services the purification equipment.
- Delivery Personnel – Handles product delivery for customers if the business offers this service.
