Grease traps and kitchen wastewater protection
Passway™ grease traps for kitchens, drains and wastewater protection
Passway™ is a practical grease-trap range for capturing fats, oils, grease and food-related solids before they travel further into drainage pipework or downstream wastewater systems.
Passway™ grease traps help reduce FOG loading on downstream pipework by creating an accessible capture point close to the kitchen, where retained grease and solids can be inspected and removed during routine servicing.
The range uses solids interception, controlled wastewater flow, internal baffles and gravity separation. Lower-density fats, oils and grease rise within the chamber while heavier material can settle or be retained before the wastewater continues through the outlet.
Built from durable polypropylene and designed around accessible servicing, Passway™ grease traps provide a practical grease-management option for domestic, off-grid and commercial kitchen applications.
Best suited for: commercial kitchens, food-preparation areas, cafés, domestic kitchens, staff facilities, small food-service sites and kitchen wastewater protection projects.
- Captures fats, oils, grease and food-related solids before they travel further through drainage pipework.
- Helps reduce FOG loading on downstream drainage, septic and wastewater systems.
- Useful where kitchen wastewater feeds grease-sensitive greywater systems, pumps or wastewater treatment equipment.
- Accessible internal components support routine inspection and cleaning.
- Different product and connection configurations are available to suit different kitchen and plumbing requirements.
- The Passway™ range is supported by independent product testing against BS EN 1825-1, with model-specific evidence applying to the product supplied.
Selection and New Zealand compliance: the correct grease trap should be selected from the connected fixtures, expected peak wastewater flow, grease and solids loading, plumbing arrangement and servicing requirements. BS EN 1825-1 product evidence may support a New Zealand Alternative Solution where required, together with the applicable G13, sanitary plumbing, drainage and wastewater-network requirements.
The outlet from a grease trap remains wastewater. A Passway™ unit reduces fats, oils, grease and retained solids but does not produce potable or purified water.
