Equipments needed to start a water refill business and where to buy them in Kenya?
The Right Machine Makes the Business
You have chosen your location. You have studied the competition. You are ready to start your portable water refill business in Kenya.
But the machine you choose will make or break you.
A cheap, undersized system will fail within weeks – leaving you with angry customers and a broken investment. A well-chosen commercial system will give you years of reliable service and steady income.
This guide lists every piece of equipment you need, explains what each one does, and tells you where to buy them in Kenya – starting with the best partner for your core purification system.
The Core Equipment List for a Water Refill Business
Here is the complete equipment list, from the heart of your operation to the finishing touches.
1. Water Purification System (The Heart of Your Business)
This is your most critical purchase. It treats raw water (borehole or municipal) into safe, great-tasting drinking water.
For borehole water or high TDS: A commercial reverse osmosis machine is the gold standard. It removes 99% of contaminants – salts, heavy metals, bacteria, and dissolved solids .
For municipal water (low TDS): An ultrafiltration (UF) system may be sufficient, removing bacteria and sediment while preserving healthy minerals .
What to look for in a commercial RO machine:
- Daily output matching your expected sales (e.g., 500–1,000 litres per hour) .
- Multi-stage filtration: sediment filter, carbon filter, and RO membrane .
- Commercial-grade components built for continuous daily operation.
- Local availability of spare parts and servicing.
Estimated cost: Ksh 150,000 – 500,000+ depending on capacity .
Where to buy in Kenya:
- House of Maji (https://houseofmaji.com/) – Your best partner. They offer custom-designed commercial reverse osmosis machines, certified water analysis, professional installation, and nationwide servicing. They have already helped 44+ refill businesses get started.
2. Raw Water Storage Tank
You need a tank to store untreated water before purification, ensuring you never run out of stock during peak demand .
Recommended: Food-grade plastic or stainless steel tank, preferably 3,000 litres or larger .
Estimated cost: Ksh 15,000 – 50,000 .
Where to buy: Hardware stores, tank manufacturers (e.g., Kentank, Roto Tanks), or your purification system supplier can often source one.

3. Treated Water Storage Tank
Purified water must be stored in a clean, enclosed tank before dispensing to customers.
Recommended: Food-grade clear tank (so you can monitor water level) or stainless steel tank. Needs to be connected to your filling station or ATM .
Estimated cost: Ksh 30,000 – 100,000 .
Where to buy: Same suppliers as raw water tanks. Ensure the tank is new and food-grade.
4. Water Vending Station / Filling Line (The Dispensing Unit)
This is where customers pay and fill their containers. It can be a simple manual filling line or an automated “water ATM”.
Manual Filling Line: A table with several taps where an attendant fills bottles manually. Good for high-volume, low-cost setups .
Water Vending ATM: An automated, coin or token-operated machine (often with M-Pesa integration) that dispenses a precise amount of water . It includes features like bottle rinsing, UV sterilization, and a PLC system that records daily sales .
Estimated cost: Ksh 80,000 – 250,000 depending on taps and automation .
Where to buy:
- Phynetech Limited – Specialises in water vending stations, offering various configurations (cabinet, table type, manual) with KEBS compliance .
- Saset Ltd – Provides water ATMs with M-Pesa integration .
- Trivon Trading – Offers complete refill station setups, including bottle rinsers and filling lines .
5. Bottle Rinser
A simple device that cleans the inside of customer containers before filling. Essential for hygiene and customer trust .
Estimated cost: Ksh 20,000 – 60,000 .
Where to buy: Often bundled with vending stations or filling lines from suppliers like Phynetech or Trivon Trading .
6. UV Sterilization System
An extra layer of protection that neutralises bacteria and viruses in the treated water before it reaches the customer .
Estimated cost: Often integrated into the RO machine or vending station.
Where to buy: Part of a complete system from a water treatment specialist.
7. Seals, Caps, and Bottles
You will need tamper-evident seals and caps for bottles (especially 20-litre jerrycans) to prevent spillage and tampering during transport . You may also sell empty bottles.
Estimated cost: Ksh 20,000 – 50,000 initial stock .
Where to buy: Plastic manufacturers and packaging suppliers across Kenya.
8. Branding, Signage, and Consumables
A bright, readable sign is essential for attracting customers. You will also need cleaning supplies, wipers, and a clean working environment .
Estimated cost: Ksh 10,000 – 30,000 .
Where to buy: Local sign writers and hardware stores.
Licenses and Permits (Critical for Operation)
Remember that the equipment is only half the picture. You must also secure:
- Single Business Permit (County Government)
- Health/Food Handling Permit (County Health Department)
- Water Quality License (Ministry of Health)
- NEMA Compliance (for wastewater disposal)
- KEBS Certification (for equipment and water quality) .
Good news: Companies like House of Maji can help you acquire these licences as part of their service package, ensuring you start legally.

Beyond Refill Businesses: Equipment for Schools, Institutions, and NGOs
The same commercial water treatment systems used for refill businesses are often exactly what larger organisations need for their own water supply. They require high-volume output for hundreds of students, staff, or beneficiaries.
For boarding schools, universities, and hospitals: A commercial reverse osmosis machine (e.g., RO500L) can be scaled up or down to serve a campus, providing centralised, high-purity water for drinking, cooking, and sterilisation .
For NGOs in remote areas: Look for containerised or solar-powered reverse osmosis machines that are self-contained and easy to deploy.
Where to buy: House of Maji is an excellent partner for these institutions, offering custom system design and nationwide support based on your specific water quality results.
