How to Launch a Water Refilling Business From Scratch

A Practical Startup Guide to a Water Refilling Business:

Business Overview

A water refilling business treats potable supply, usually municipal, and dispenses drinking water by the gallon. Customers bring their own containers or buy jugs in-store. The core is a compact treatment line—typically reverse osmosis, carbon filtration, and UV—connected to clean, easy-to-use dispensers.

Many operators add simple options. You might mineralize or alkalize the finished water, sell ice made from treated water, and offer jugs, caps, pumps, and stands. Some jurisdictions require specific permits for water or ice vending machines, so you’ll confirm that early.

This guide keeps you on the startup track only. You’ll decide if the business fits, plan the launch, secure permits, build the space, install compliant equipment, and complete final inspections. Ongoing operations are outside this guide.

Starting a Business Foundation

Start by testing fit. Do you want day-to-day customer service work? Are you prepared for health inspections, cleaning routines, and simple equipment maintenance? Consider time, savings, credit, and family support. These points matter before you spend.

Study the model you want. You can run a staffed refill shop or place one or more vending heads within a store. You might build from scratch, buy an existing shop, or look at franchise systems. Each path has different costs, controls, and timelines.

Use these primers to think clearly before you commit: Points to consider before starting a business, Inside look at the business you’re considering, Business startup steps, New business checklist, Owning a franchise, and Buy a business or build from scratch.

Requirements for permits and taxes vary by jurisdiction; you will verify them where indicated in this guide.

Step 1: Research the Local Opportunity

Map where people already buy refills. Visit supermarkets, vending kiosks, and independent water stores. Count parking spots and watch how customers handle heavy jugs. Note which locations feel easy to access with a car and cart.

Check the site basics. You need a reliable potable water source, a sanitary drain for RO reject/waste lines, and enough power for pumps and UV. You also need a layout that keeps the refill area clean and separate from dirt and splash.

Visit the city zoning portal to confirm a retail use at the address.
Check the local health department site to see if your model is “retail food” or “vending.”
Call the water utility to ask about required backflow prevention.
Find the Weights & Measures office if you plan to charge per gallon.
Walk the space and note ADA customer routes and reach ranges you must meet.

Varies by jurisdiction. How to verify locally: City/County Planning & Zoning portal — search “zoning map” and your address; Local Health Department — search “retail food establishment permit” or “water vending machine”; Water Utility — search “backflow/cross-connection”; State/County Weights & Measures — search “commercial measuring device inspection.”

Step 2: Define Your Model and Pricing

Choose a staffed refill counter, self-serve vending options, or a mix. Decide whether you will offer ice made from treated water. Some states license each vending machine and require routine water testing and consumer notices at the machine. A staffed shop may be permitted as a retail food establishment with plan review and inspection.

Pick a simple pricing method. Charging per gallon may place your meter under Weights & Measures rules. Charging per container size can be simpler but still must be clear to the customer. Either way, post prices so customers know what to expect.

If multiple competitors sell “purified” water nearby, consider differentiation. Late hours, easy parking, clean counters, and fast, drip-free dispensing often matter more than complex upgrades. You can test add-ons, such as mineralized water, after opening.

Step 3: Build a Practical Plan

Write a plan that helps you decide, not one that sits in a drawer. Focus on location, permits, equipment, buildout, and the sequence to open. Use realistic timelines. Include cash needs until the shop pays for itself.

Use these guides to structure your thinking: Write a business plan, Create a Step statement, Understand supply and demand, and Set your pricing. A tight, short plan is better than a long, vague one.

List permits you will need, inspections you must pass, and the order they happen.
Get written quotes for equipment, installation, plumbing, and signage.
Add deposits, fees, and pre-opening testing costs.
Plan a small reserve for delays or re-inspections.

Varies by jurisdiction. How to verify locally: Health Department — search “plan review” and “retail food” or “water vending”; Building Department — search “tenant improvement” and “plumbing permit.”

Step 4: Line Up Funding

Decide how you will pay for the startup. Many owners mix savings with a small loan or supplier terms. Separate costs into equipment, tenant improvements, permits/fees, and working capital. That helps you see what can be financed and what must be paid in cash.

Collect documents your lender or partner will ask for. You will need your plan, quotes, timeline, and basic financial projections. Keep your assumptions simple and based on the local research you have done.

Confirm total cash needed to open, not just to buy equipment.
Ask vendors about lead times and payment schedules.
Set a target opening date and work backward to lock key steps.

Step 5: Choose Structure and Register

Pick a structure that fits your risk and tax needs. Many small owners choose an LLC, but the right choice depends on your situation. File with your Secretary of State and register a DBA if your trade name differs from your legal name.

Get an EIN from the IRS. If your state taxes retail water or ice, register for sales/use tax with the state revenue department. If you will have employees, set up employer accounts for withholding and unemployment insurance as required by your state.

Register your business with the Secretary of State (and DBA if needed).
Apply for an IRS EIN online.
Register for state sales/use tax if applicable to your products.
Open a business bank account after you have your documents.

Varies by jurisdiction. How to verify locally: Secretary of State business portal — search “register a business” and your entity type; IRS — search “Apply for an EIN”; State Department of Revenue — search “sales tax permit” and “bottled water” or “food/beverage.”

Step 6: Health, Weights & Measures, and Building Approvals

Identify your permit path. Many jurisdictions treat refilling as a retail food establishment with plan review, pre-opening inspection, and an annual permit. Some states also permit or license each water or ice vending machine. The permit type affects your drawings, equipment lists, and the inspector who visits you.

If you charge by the gallon, your meter may be regulated as a commercial measuring device. States and counties often follow NIST Handbook 44. That can mean device registration, inspection, and sealing before you sell. Ask your local office for steps and timing.

Coordinate early on plumbing. You may need a plumbing permit for new supply, drain, and RO reject lines, and a backflow prevention assembly approved by the water utility. Plan the installation so it is easy for the inspector to see and approve.

Submit health plan review drawings and equipment specs as required.
Contact Weights & Measures if selling per gallon; ask about inspection/sealing.
Apply for building and plumbing permits for the tenant improvement.
Confirm backflow device type and testing with the water utility.

Varies by jurisdiction. How to verify locally: Local Health Department — search “retail food permit” or “water vending machine”; Weights & Measures — search “commercial measuring device inspection” or “device sealing”; Building Department — search “plumbing permit food establishment”; Water Utility — search “backflow/cross-connection program.”

Step 7: Design the Space and Flow

Keep the refill area clean and easy to sanitize. Use smooth, non-absorbent finishes around dispensing points. Plan splash protection, good lighting, and a work surface for jug handling. Keep chemicals and tools away from the clean area.

Make access simple. Leave clear paths for customers carrying heavy jugs. Review ADA reach ranges for your counter, controls, and payment device. Post prices where customers can read them without blocking traffic.

Draw the floor plan with equipment, sinks, dispenser heads, and drains.
Plan for storage of new jugs, caps, and replacement filters.
Place a trash/recycle station near the exit to prevent spills and clutter.
Set a visible service/cleaning log location the inspector can check.

Varies by jurisdiction. How to verify locally: Health Department — search “food establishment plan review checklist”; ADA — see the public guidance on accessible design; Building Department — search “tenant improvement submittal checklist.”

Step 8: Choose, Document, and Install Equipment

Select treatment units and dispensers certified to relevant NSF/ANSI standards. Keep specification sheets and manuals for your submittal and for the inspector. Confirm your plumber and installer know the equipment connections, waste lines, and venting.

Document chemicals and sanitizers you will use. Keep Safety Data Sheets in a binder and label containers. Train staff on safe handling and your cleaning schedule. This preparation saves time during inspection and helps you run safe from day one.

File equipment spec sheets and NSF/ANSI certifications.
Record serial numbers, filter/membrane part numbers, and service intervals.
Keep SDS for sanitizers and cleaning agents in a visible location.
Create a one-page sanitation SOP for daily, weekly, and monthly tasks.

Step 9: Branding Basics—Name, Logo, Web, and Signage

Pick a clear name that signals what you sell. If you filed a DBA, use it across bank, website, and permits so customers see one identity. A simple logo and color palette help you look professional without slowing the launch.

Publish a basic website with hours, location, refill types, and parking tips. Add two or three photos that show the clean dispensing area. Order an exterior sign customers can see from the street and a price board customers can see from the counter.

Create a simple identity: name, logo, and color use (Corporate identity package).
Launch a basic site with map and hours (Build a business website).
Order cards for partners and vendors (Business cards).
Approve exterior/interior signs (Business signage).

Varies by jurisdiction. How to verify locally: City Sign Permit page — search “sign permit” and your zoning district; Confirm landlord sign criteria if in a plaza.

Step 10: Line Up Suppliers and Services

Secure steady sources for filters, membranes, UV lamps, and sanitizer. Add a supplier for new jugs and caps. Price lab services for bacteriological testing and any additional testing your health department requires. Ask for sample turnaround times.

Line up service providers who keep you moving. You may need a plumber for final adjustments, an electrician for outlets, a backflow tester, and a technician for ice machines if you offer ice. Keep their contacts near the phone for quick calls during pre-launch.

Approve terms with filter and jug suppliers; note lead times.
Open an account with a certified lab for required testing.
Schedule backflow installation and testing with the utility’s approved tester.
Arrange trash and recycling service sized for jugs and packaging.

Step 11: Insurance and Employer Setup

Speak with a broker about general liability, property, and product liability coverage. If you will hire, check whether your state requires workers’ compensation coverage at your headcount. Confirm what your lease requires before you sign it.

Prepare basic employer files if you will bring on staff. Post required labor notices. Set up payroll and keep employee training records for chemical safety and sanitation.

Request certificates of insurance that match your lease requirements.
Confirm state workers’ compensation thresholds and register if required.
Set up payroll and employee files with training sign-offs.

Varies by jurisdiction. How to verify locally: State workers’ compensation agency — search “employer coverage requirements”; State labor department — search “workplace posters” and “new employer.”

Step 12: Prepare Consumer Notices, SOPs, and Testing

Some jurisdictions require notices at each machine or dispensing point. The notice may include operator name and contact, treatment method, last service date, and water test results or schedule. Draft the notice now so you can post it right after installation.

Set your testing calendar. Many jurisdictions require periodic bacteriological testing for each dispensing device. Your health department will tell you what to test, how often, and where to send samples. Put those dates on your calendar and with your lab’s contact.

Create required consumer notices and place holders where they will be posted.
Confirm test frequency and parameters with the health department and your lab.
Print a sanitation and filter-change schedule for the inspector to review.

Varies by jurisdiction. How to verify locally: Health Department — search “water vending testing” or “retail water sampling” and your county; Ask for the “plan review” checklist to confirm postings and records required.

Step 13: Final Pre-Launch—Dry Runs and Inspections

Install equipment and run it before the inspection. Check flow rates, look for drips, and confirm drains handle RO reject and rinse water. Flush the system as directed by the manufacturer. Clean and sanitize the dispensing area and log the work.

Set your price board. If selling per gallon, confirm the meter displays, the receipt reads clearly, and you know who to call for a device seal if required. Stage jugs, caps, and a cart so customers can move easily through the space.

Schedule health inspection; have logs, notices, and SOPs ready.
Schedule building/plumbing finals; uncover work so the inspector can see it.
Schedule Weights & Measures if required for your meter.
Place ADA routes and reach-range checks on your floor plan for quick review.

Varies by jurisdiction. How to verify locally: Health Department — search “pre-opening inspection”; Building Department — search “final inspection checklist”; Weights & Measures — search “device sealing appointment.”

Products and Services You Can Offer

Your core product is purified water refills. Most systems use RO plus carbon and UV to produce clean, good-tasting water. You can offer basic, mineralized, or alkaline options if you install the right post-treatment cartridges. Keep the menu short at launch.

You can also sell distilled water if you install a distillation unit. Many customers buy jugs and caps, manual or electric pumps, and ceramic or countertop dispensers. If permitted, you can add ice made from your treated water. That may require a separate permit, so confirm during your research step.

Delivery to homes and offices is possible later. It often changes permit scope and insurance. Start simple with in-store refills and add services after you understand local demand and rules.

Pros and Cons to Weigh Before You Commit

Refill water has steady demand. It uses a small footprint and a simple product line. Certified equipment and a clean design can satisfy regulators and customers. Once set up, the system is straightforward to operate.

The rules can be strict. Expect plan review, inspections, and ongoing testing based on your jurisdiction. You may need backflow protection, plumbing permits, and Weights & Measures oversight if you sell by the gallon. Permitting steps add time and cost to the launch.

Decide with facts. Use the foundation links above to test your fit, confirm local requirements, and estimate real costs. A clear plan and patient sequencing reduce surprises.

Marketing Basics for Launch

Keep marketing simple at first. Make it easy for people to find you, park, and refill quickly. A clean counter, bright lighting, and a clear price board go further than complex offers. Publish your hours and a map on your site and show photos of the dispensing area.

As you get ready to open, line up a few low-cost actions. Create a short marketing plan with your target neighborhoods and simple messages. Show why your location is easy and your water is clean. Keep the tone factual and practical.

Draft a one-page plan (Create a marketing plan).
Publish your site and map (Build a business website).
Place your exterior sign and price board (Business signage).
Carry a few cards for local introductions (Business cards).

Risk Controls Before Opening Day

Address basic risks now. Confirm your insurance binder dates match your inspection dates. Walk the ADA route with a tape measure. Check labels on chemicals and keep Safety Data Sheets on site. Make sure your team knows the sanitation steps and can show the log to inspectors.

If you will hire, confirm employer registrations and post required notices. Practice customer flow with a cart and two jugs. Fix any trip points, drips, or bottlenecks before the public sees them.

Review coverage with your broker (Business insurance).
Plan staffing and timing (How and when to hire).
Do a final self-audit (Startup mistakes to avoid).

Varies by jurisdiction. How to verify locally: State workers’ compensation board — search “employer coverage”; State labor department — search “workplace posters”; Local health department — search “sanitation log” or “food safety plan” guidance.

Your Opening Sequence

Once plan review is approved, complete the tenant improvement and install equipment. Flush, sanitize, and document the process. Post notices and prices. Stock jugs and caps. Stage a cart and a mat to keep floors dry.

Book final inspections in this order if possible: building and plumbing, Weights & Measures (if applicable), then health. After approvals, run a soft opening for a few days. Use that time to confirm flow, restock parts, and answer early customer questions. Then announce your full opening.

If any requirement in this guide varies where you live, verify it before you spend. How to verify locally: Health Department — “retail food permit” or “water vending machine permit”; Secretary of State — “register a business”; State Department of Revenue — “sales tax permit”; Water Utility — “backflow/cross-connection”; Weights & Measures — “commercial measuring device inspection.”

101 Tips for Running Your Water Refilling Business

A water refilling business treats potable supply and dispenses drinking water into customer containers. Your success rests on clean design, compliant permits, and a smooth refill experience. Use these tips to plan, launch, and run a reliable shop without guesswork.

Rules and terminology can vary by state and city. Always verify local requirements with your health department, building officials, water utility, and Weights & Measures office before you spend money.

What to Do Before Starting

Confirm zoning for your address and verify that a retail food or vending use is allowed at your site.
Call your local health department to confirm whether your model is permitted as a retail food establishment, as vending, or both.
Contact your water utility to learn which backflow prevention device is required and how testing is handled.
Ask your State or County Weights & Measures office if charging by the gallon requires device registration and sealing.
Walk the store with a tape measure to plan ADA routes, reach ranges, and counter heights before you draw plans.
Estimate total cash to open, including equipment, permits, tenant improvements, testing, and a reserve for delays.
Visit competitors at different times of day and note parking, flow rate, and cleanliness standards customers expect.
Choose your model—staffed refill counter, self-serve vending heads, or a mix—based on local rules and demand.
Create a one-page launch timeline that lists plan review, permits, inspections, and the order they occur.
