Every year hundreds of entrepreneurs across India look at the packaged drinking water business and decide it is a safe bet. Demand is steady, the product is simple and the market is huge. What surprises many first-time owners is how much equipment sits between a borewell and a sealed bottle on a shop shelf. Getting the machinery list right at the start saves money, space and a lot of frustration during licensing and commissioning.
Here is a practical checklist, grouped by stage, that you can use when planning a small to medium packaged drinking water plant.
Stage 1: Raw Water Treatment
Before anything is bottled, water has to meet the standard your licence requires. A typical treatment train includes:
- Raw water storage tank and transfer pump
- Pressure sand filter to remove suspended particles
- Activated carbon filter to remove chlorine, odour and organic matter
- Antiscalant or softener depending on water hardness
- Micron cartridge filters (usually 5 micron and 1 micron)
- Reverse osmosis unit sized for your daily output with some margin
- Mineral dosing system to restore taste and meet mineral requirements
- UV steriliser and ozone generator with a contact tank
The size of each unit depends on your raw water report, so get a full chemical and microbiological test done before ordering anything.
Stage 2: Bottle Preparation
Most plants either buy ready PET bottles or blow them in-house from preforms. If you blow your own, you need a blow moulding machine, an air compressor (high pressure for blowing, low pressure for pneumatics), an air dryer and a chiller. In-house blowing reduces bottle cost and storage space, but it adds power load and maintenance.
Stage 3: Rinsing, Filling and Capping
This is the heart of the plant. For outputs below roughly 1,000 bottles per hour, a semi-automatic or linear automatic filler can work. Above that, a rotary rinsing-filling-capping monoblock is the sensible choice because it keeps bottles under control from rinse to cap and minimises human contact. Look for:
- Stainless steel contact parts (SS 304 minimum, SS 316 preferred for wetted parts)
- Gravity or level-sensing fill valves suited to still water
- A capping turret that matches your cap type and neck size
- Easy changeover parts if you plan multiple bottle sizes
Stage 4: Labelling and Coding
A BOPP or shrink-sleeve labelling machine gives bottles their shelf identity. For shrink sleeves you also need a steam or hot-air shrink tunnel. A batch coding machine, typically an inkjet printer, prints the batch number, packing date and best-before date, which are mandatory declarations.
Stage 5: Secondary Packing
Bottles are usually shrink-wrapped into packs of 12 or 24 using a web sealer or automatic shrink wrapper. Larger plants add case packers and palletisers later as volumes grow.
Utilities and Infrastructure People Forget
- Adequate three-phase power with a backup generator
- An in-house laboratory with equipment for the tests your licence demands
- Separate raw material, production and finished goods areas with proper flooring and drainage
- Conveyors linking each machine, sized for your target speed
Planning for Growth
The most common regret we hear is buying a line that is exactly the right size for year one. If your market grows, an undersized filler becomes a bottleneck, and replacing it costs far more than buying slightly bigger in the first place. Discuss realistic three-year volumes with your machinery supplier and choose equipment with some headroom.
Getting Help With the Layout
A good layout keeps bottle flow in a straight line, separates clean and unclean zones and leaves room for maintenance. Hilden helps new water plants plan machinery and line layout together, so that each machine is matched to the next and the plant is ready for inspection from day one.
