Product-contact system
Include treated-water tanks, product piping, pumps, valves, filler bowl or flow path, filling valves and any sampling or recirculation connections. Define drainability and cleaning boundaries.
Factory planning for water bottling projects
Make hygienic control part of plant design
Cleaning and sanitation are operating systems, not final commissioning tasks. Hygienic design, zoning, water and chemical conditions, safe access, drainage, procedures, verification and production release should be connected before the equipment and building layouts are frozen.

01
Different parts of the plant need different controls.
Include treated-water tanks, product piping, pumps, valves, filler bowl or flow path, filling valves and any sampling or recirculation connections. Define drainability and cleaning boundaries.
Review bottle rinsing, air conveyors, cap storage and feeding, exposed closures, filler enclosure and the controls that protect cleaned packaging before sealing.
Separate wet processing, packaging, chemical storage, waste, maintenance, staff access and warehouse activities. Provide cleanable finishes, drainage, ventilation and pest-control interfaces.
02
The method follows the equipment, soil, product and validated operating requirement.
| Method | Typical application | Design needs | Records to retain |
|---|---|---|---|
| Clean-in-place | Closed tanks and piping designed for circulation | Flow, concentration, temperature, time, return and complete drainage | Cycle parameters and verification result |
| Clean-out-of-place | Removable product-contact or format components | Safe disassembly, identified parts, wash area, protection and reassembly | Part identity and release check |
| Manual cleaning | External machine and room surfaces | Accessible surfaces, tools, chemical control, safe isolation and drainage | Area completion and inspection |
| Sanitation step | Microbial control after effective cleaning | Approved agent or method, contact conditions and residue control | Application conditions and release evidence |
03
A written recipe cannot compensate for unstable inputs or unsafe handling.
Define approved chemicals, concentration preparation and verification, compatibility, dosing or mixing, labeling, storage, spill control, protective equipment and disposal requirements.
Specify rinse-water quality, available flow, pressure and temperature; heating and cooling limits; recovery or discharge route; and how final rinse conditions are checked.
Provide isolation, lockout, confined-space review where applicable, ventilation, guards, safe access, hose and tool control, and a response method for exposure or incorrect chemical use.
04
Verification demonstrates that the defined method was completed and remained effective.
Use relevant visual inspection, cycle records, concentration checks, rinse conditions, swabs or microbiological methods according to the site quality plan and local requirements.
Define what happens after an incomplete cycle, failed verification, long shutdown, maintenance intrusion, utility interruption or suspected contamination.
Reassess the method when equipment, chemicals, water conditions, product, bottle, operating schedule or regulatory requirements change. Preserve approved versions and training records.
Buyer questions
Not every system uses the same method. The need depends on process design, hygienic risk, equipment cleanability, product and applicable requirements. The cleaning boundary must still be defined.
Not as a universal rule. Effective cleaning and microbial control require a defined, verified method compatible with the equipment, soil, water and target conditions.
Qualified site production, quality, sanitation, safety and technical roles should approve them with equipment and chemical information and applicable local requirements.
Request hygienic design details, cleaning boundaries, compatible agents and limits, cycle requirements, drainability, dismantling instructions, safety needs, verification points and training.
