01 Answer first
How should dirty and clean zones be separated in a 5-gallon water plant?
Map returned-bottle receiving, inspection, decapping and external soil handling on the uncontrolled side; define the validated wash transition; then protect cleaned containers, filling and closing from return traffic, waste, chemical handling and uncontrolled personnel. Coordinate drainage, air movement, access, rejects and maintenance with local design review.
02 Where it fits
Position in the project journey
Factory zoning - after process definition and before building, drainage and equipment-layout approval.
03 Buyer inputs
What the buyer should prepare
- Verified building, doors, columns, levels, drains and vehicle access
- Return volumes, storage policy, inspection, reject and dispatch operations
- Personnel, visitor, chemical, waste, forklift and maintenance routes
- Applicable local food, building, fire, environmental and worker-safety review route
04 Allot Tech and manufacturing-resource inputs
What should be clarified or provided
- Equipment footprints, elevations, guards, doors and maintenance clearances
- Bottle flow and defined point where clean-container protection begins
- Utility, chemical, drainage, ventilation and reject connection requirements
- Installation access, clean transfer and operating-interface assumptions
Allot Tech coordinates requirement, quotation and project communication. Detailed engineering, manufacture, testing, documentation and confirmed service are performed by selected manufacturing resources according to the signed scope.
05 Technical scope
Questions and work to control
Map the Return Route Before Placing Machines
Returned containers arrive with uncertain external condition and require storage, inspection, closure removal, rejection and washing. Define those flows and capacities before arranging the filler so dirty inventory and handling do not surround the protected process.
- Return unloading and staging
- Inspection, quarantine and reject storage
- Decapping and external-soil control
- Washer feed without reverse traffic
Protect the Clean-Container Transfer
Identify the validated final-rinse discharge and the route to filling and closing. Control distance, exposure, operator access, conveyor returns, cap supply and maintenance intervention according to the project hygiene assessment.
- Defined hygiene-transition point
- Protected washer-to-filler transfer
- Controlled cap and operator access
- Restart and container-disposition method after stops
Design Utilities and Waste Around the Boundary
Chemical make-up, washer drains, rejected bottles, wastewater, ventilation and floor cleaning can undermine zoning if routed late. Coordinate gradients, drain capacity, utility points, service clearance and local environmental responsibilities with the actual equipment.
- Chemical receiving and safe preparation
- Wash-water and wastewater routes
- Floor drainage and splash control
- Waste removal without clean-zone crossing
Buyer questions answered
Practical answers before you request a quotation
Is a wall always required between every dirty and clean activity?
The final physical controls depend on the process, risk assessment and local requirements. The project must still define and protect the transition.
Where should rejected bottles go?
To a controlled quarantine or reject area outside the clean route, with status identification and disposition responsibility.
Can a supplier layout be used for construction?
A supplier concept is an input. Qualified local parties must verify building, structural, drainage, fire, safety and regulatory requirements.
Why overlay maintenance flow?
Technicians, tools and removed parts can cross hygiene boundaries unless access and isolation routes are planned.
06 Responsibility
Assign the owner before the work is due
Land, building and civil work, permits, import and customs, local taxes, site utilities, unloading, lifting, local labor, travel support and commissioning materials are not automatically included. Confirm every responsibility before order.
07 Common risks
What commonly creates avoidable uncertainty
- Returned bottles or waste cross the protected clean-container route
- Drainage or aerosols move from dirty operations toward filling
- Maintenance access bypasses the intended hygiene transition
- A generic drawing is treated as a local construction or compliance plan
08 Acceptance or completion
How to know the stage is complete
The concept layout is approved when container, people, waste, chemical, maintenance and forklift flows are overlaid on verified building data, the dirty-to-clean transition is explicit, drainage and utilities support it, crossings are controlled, and local qualified designers own final compliance.
09 Required documents
Records that support the decision
- Verified building and site-constraint drawing
- Dirty, transition and protected-zone layout
- Material, people, waste and maintenance flow overlays
- Drainage, utility and local-design action register
Evidence basis
Official references and project limits
These primary sources support the general planning principles used in this guide. The rules, evidence and responsible authority for the actual project country must still be confirmed locally.
